Emergency indication in carsRange. Rover

The car of this class as Renge Rover has a reliable light indication, which is displayed on the scoreboard, allowing to judge a malfunction of a particular node and perform the necessary actions or adopt the desired solution.

Possible malfunctions in the engine control system

The main indicator among the entire group of elements of the indication is "Check-Endin" (English Check-Engine) - check engine. This indicator lights up for a short time when the ignition is turned on when all indicators are tested. After that, he should go out. If he caught fire during the movement or works in flickering mode - this means the presence of a malfunction in the engine. The panel can also highlight the inscription - "engine malfunction" and this means that some kind of malfunction arose and it is necessary to contact the car service without delay.

The most likely reasons for sunbathing the "Check Engine" indicator on diesel engines

• In diesel models, Range Rover, versions of 3.0 TD, 3.6T. TD, 4.4 TD, the lighting of this indicator may be caused by the fault of the exhaust gas recycling valves - EGR. Also, the high pressure fuel pump (TNVD) or pump paging pump, which is located in the fuel tank can be faulty. Maybe one of the fuel injectors is faulty.
• Renja Rover 3.0 TD quite often fails the system of overhead streams through the bypass valve. This system includes vacuum highways, valve itself and control electromagnetic valve. Diagnostics are checked all highways, wiring and only then replace bypass.- Valve.
• Weak place of all models, and especially Renge Rover 3.6 TD are rubber superchard hoses. They are not very reliable and often torn, so the sensors are "see" an inappropriate amount of air in the highway and the system translates the engine into a limited mode, while the scoreboard lights up - "power limit". In order not to be in an unpleasant situation, it is necessary every 20-30 thousand km. Mileage, these hoses replace.

In places of connecting air hoses, oil stains can be observed, but it is not a problem, since the intake system sucks the surplus oil, which is burned in the combustion chamber, preventing them in the atmosphere. Why is the damage to the hoses. When working with diesel turbines of the car, Renge Rover, the hoses are constantly in the inflated state, and during the passage, the hoses pulsation occurs - they are filled with air, then compress. From this, their tightness is disturbed, and they are covered by cracks and rush.

When the tightness of air hoses, oil droplets flying out of the air nozzle fall on the cooling system hoses, and since the hoses of the antifreeze system are not oil-resistant, then they will buoy under the action of oil and can jump off the seats.

In practical operation of cars, this happens quite often, therefore, as soon as strong oil spots appear on air hoses, the nozzles must be changed immediately. Diesel engine car Renzh Rover 3.0 TD is a hose coming from an intercoulera (heat exchanger) to the throttle node. This hose is often rushing, which leads to the restriction of the power of the diesel engine.

The most serious trouble that "Check Engine" can be indicated is a malfunction of any of the turbines. The turbine turbines themselves are quite reliable, but they are equipped with an electron-mechanical actuator, a supercharging flow. The vacuum actuator is designed to protect the turbine from overloads on large revs. Over time, the rod rod or coking holes of the rod can occur, after which the controlling solenoid mechanism is not able to move the rod and the control system translates the engine into a limited mode. The first thing to be done is to try to develop the actuator rod manually. If it did not work, then the turbine replacement is required, since the actuator and electromagnetic control valve are not for sale separately, which eliminates its replacement. Sometimes an appeal to the service center can help, but there will not give 100% warranty.

The most likely causes of the lighting of the indicator "Check. Engine»On gasoline engines

On Renge cars, gasoline engines are installed on cars.

These are models:

• 4.2 SC (Supercharger)
• 4.4 Na (atmospheric)
• 5.0 SC (Supercharge) since 2010
• 5.0 Na (atmospheric) C 2010

The most common cause of the "Check Engine" indicator is a skipping ignition in any cylinder. This malfunction is eliminated by cleaning injectors or replacement of spark plugs. The following, very common cause of a malfunction of gasoline engines Renge rover is a submission of a refinement or receded mixture. This can be caused by the presence of leaks during air superstay from the air line or a decrease in the performance of the fuel pump itself directly in the fuel tank.

On the engines 4.2 SC and 5.0 SC on the error code, during diagnostics, it is clear that the fuel supply pump performance is clearly fixed. On the engine 4.4 Na, there is no pressure sensor, and it will not be possible to obtain data using the diagnostic system, but if the service service has transitional connections and pressure gauges, then this defect can be revealed.

A sufficiently frequent cause of a malfunction in gasoline engines Renge rover is the refusal of oxygen sensors in the system of catalytic neutralization of exhaust gases or a malfunction associated directly with catalysts. The cost of one branded catalyst is 90 000 rubles, and on the Renge car the rover is two, moreover, it is necessary to take into account the cost of oxygen sensors.

As a result, a sufficiently impressive amount is obtained, so many car owners prefer to put so-called "deceivers" or in general removed catalysts. This leads to the fact that the work of the entire logic of the gasoline engine control system is disturbed, since it is based on the testimony of oxygen sensors of the exhaust gas purification system. And when instead of standard catalysts, "Blits" or catalysts are completely removed - this leads to inadequate operation of the control system. A reasonable way out of this situation is to appeal to such service services that not only change catalysts to more cheap, but can also reprogram the control system.

On the engine 4.2 SC (Superchardger), such a malfunction is often found as a failure of an additional electric pump system of the supercharger. As a result, the supercharger overheats the thermal sensors, through the control system, limit the engine power. Of course, before changing the electric pump, it is necessary to check its power supply system.

On Renge cars, the rover with engines 5.0 SC and 5.0 Na very often occurs a malfunction associated with the chains of the gas distribution mechanism. It all begins with the fact that when running 50,000 km or more, noise can be observed in the front of the engine, which with an increase in the mileage are enhanced. This is caused by the weakening of the tension of the chains of gas distribution. This is the cause of the violation of the corners of the gas distribution, which causes the engine malfunction indicator.

Since 2010, all these engines began to install a VVT clutch (gas distributor phase change system) on all camshafts, which complicated the circuit circuit system. In addition, not quite a successful design of the chain tensioners causes a weakening of the tension and the tension of the chain with all the consequences that arise. In this case, it is necessary to change all the chains, tensioners and all additional items. In our services, the price of this service is within 110,000 rubles.

One of the full-time malfunctions, on Renge cars, equipped with gasoline engines, is the defect of the fuel vapor cleaning system in order to reduce their toxicity. To comply with environmental standards, fuel pairs are discharged through an adsorbing filter and when the removal and cleaning system is defective - the engine fault indicator is triggered. Although, as a rule, the power of the engine does not decrease, the fuel consumption does not increase. If such a fault is defined by the error code during diagnostics, it is required to replace the adsorbing filter and the check valve on the fuel line. Such a malfunction occurs on runs from 120,000 km and more.

Critical warning signal

A critical warning signal is indicated by red light and, in fact, warns of a critical situation associated with any vehicle. Together with the critical warning indicator, another indicator lights up, which allows us to specify the fault or an information text appears, which explains the cause of the critical warning. If the text is not visible, you must scroll through all messages by clicking the "OK" button, which is located on the steering wheel.

Oil pressure indicator

The oil pressure indicator in the system is one of the most important indicators on the Renge Rover's information panel. When you turn on the ignition, this indicator should be lit and go out after 2-3 seconds. If you are watching the "flicker" of this indicator, the luminescence of it for more than 3 seconds during startup or periodic signing it during the movement does not depend on the type of engine, you must immediately stop moving, and drown out the engine of your car.

First of all, it is necessary to check the oil level in the engine of your Renge Rover. With the help of an ordinary probe, this can be done quickly and simply, but if you are an electronic probe, then you need to wait 10-15 minutes after turning off the ignition. If the oil level fell below the minimum limit, it is necessary to look for the point of its leakage.

Practice shows that constantly topping the oil into the engine, and only in the case of a small leak, you can reach the car service. Such experiments are generally very dangerous - you can fully destroy the engine. Perennial practice has shown that the oil level indicator in any rover engine does not light up even when the oil level is minimal, and the display only works on the low oil pressure in the oil system, and this is too late. Consequently, as soon as the oil level indicator lit up or even flashed, it is necessary to immediately drown the engine and cause a technical assistance machine.

Brake system indicator

This indicator should light up when the ignition is turned on and a few seconds go out. If the engine of your Range Rover works, and this indicator lights red - this means the brake system defect. This, first of all, can mean a decrease in the level of brake fluid or "sticking" the float, which is extremely rare. Reducing the level of the brake fluid indicates a leakage of its Rometer Range system. The main reason is a breakdown or leakage of brake hoses. Frequently, there are problems with the electrolyney of the ABS electrolyne (anti-lock system), but then, together with the brake indicator, the ABS and DSC indicators light up. On the Early Cars Range Rover (2006-2009), this indicator glowed with bright orange light, if the brake pad sensor triggered, but the inscription was indicated on the panel: "Check the brake pads". True, it was not on all the equipment and which shoes: front or rear, was not indicated.

Parking brake indicator

This indicator lights up in red when the parking brake is turned on and goes out when the car is removed from the brake. If the "Flashing" indicator is a malfunction. All models of the car Range Rover parking brake is controlled by an electromagnetic mechanism, which pulls the cables, but the last Range Rover models since 2013 have an electromagnetic executive system, which is built into the calipers and clamps and squeezes the main root pads by performing the parking brake function.

You should know that on the most recent models of the Renge Rover car, the parking brake turns on and off automatically. You drown out the engine, and the car stood on the parking brake, you started the engine and the brake turned off. In addition, if some serious malfunction happened to the machine, the parking brake is also turned on automatically. Even if the battery is completely discharged, Renge Rover is equipped with a special backup battery for parking brakes.

For Russian conditions, it is not too convenient, since the car is even impossible to tow anyone, but the British has another mentality: to move a defective car there is a tow truck and service road services.

Parking Brake Malfunctions on Renge Rover Car

The causes of parking brake malfunctions in Renge cars Rover may be several:

• The mechanics of the parking brake pads are not adjusted and when the electromagnetic actuator pulls the cables - it occurs unevenly, which causes the triggering of the fault indicator. In this case, it is enough to adjust the mechanics of the parking brake of the car Renger Rover
• Pads of the parking brake of the car Renge Rover crumpled from wear. In the process of wear, the pads become thinner that disrupts the symmetric movement of cables and causes the troubleshooting indicator
• Fault of the parking brake cables themselves. Their external coating from friction is destroyed, dirt falls inside, moving the cable is hampered and as a result, the system is racking and the electron block failure
• The failure of the electronic control module

If the parking brake of the car's parking brake has occurred, all work must be carried out in a specific sequence. First, it is necessary to carefully inspect the parking brake cable system. If the cables of the car Renge rover is in perfect order, it is necessary to remove the brake discs and adjust the block of the parking brake. If the whole mechanical part is in perfect order, you can proceed to computer diagnostics of the electronic unit.

If the external inspection of the block gave nothing to reflash it and erase from the memory all the fault codes. If it did not help, it remains only to replace the electronic unit to the serviceable one. If on your car Range Rover has occurred with the parking brake, you always need to be ready for major expenses, because in this system everything is interconnected. First, it turns out that the cables are fluttered, then after the removal of the disks it turns out that the brake pads do not go anywhere, therefore, it is necessary to change the cable system and pads, and at the same time and drives.

In the end, it turns out that the electronic unit is also faulty, and it is located in a hard-to-reach place. Therefore, probably, it makes sense to replace everything at once, because wholesale cheaper, and ride calmly. It is important to know that the used electronic unit cannot be installed, since it is prescribed for a specific VIN (vehicle identification number) of the car and with computer diagnostics, all electronic devices of your Renge Rover can "get infected" by an outsider and the car will simply not go.

There may also be such a defect that, together with the flashing indicator of the parking brake, the brake system malfunction indicator is lit, but the parking brake works. This may be in the case when a short circuit between the individual conductors occurs from the drying of the insulation of the wires. To eliminate this defect, it is enough to find the location of the closure and exhibit the wires with poor insulation. If it happens that on your car Renge Rover, the parking brake is jammed, it can be easily removed manually. To do this, open the trunk, there, in a special pocket, there is a loop, pulling for which you can break the pads of the parking brake.

Battery charging indicator

This indicator lights up when the ignition is turned on on your car and goes out after the engine has earned. If the indicator does not go out or lights up while driving, this means that in the battery charging system of your Renge Rover is a malfunction. The most common fault, both diesel and gasoline engines, is the failure of the generator that will have to be replaced. You can give it to repair and put it again, but practice shows that repaired generators are very unreliable and in any case will have to buy a new generator.

Incandescent Candle Performance Indicator

This indicator is placed only on Renge Rover cars equipped with diesel engines. When the ignition is turned on, glows with orange, pointing to the work of the candles. You must wait to turn off this indicator and only then start the engine. Renge Rover cars Since 2010, the release is equipped with automatic, which, after pressing the "Run" button, wait for the heating of incandescent candles and only after that it will start the engine. The system exercises gas candle tests that exercise combustion chambers. True, this indicator does not signal the bad operation of the ignition candle. Even resistance measurements will not show a real picture.

The optimal check is to dismantle the candles and connect them to the voltage source. One candle is rare in 1 second second in 2 seconds, the third for an even greater period of time. They are all right, but when symptoms of cold start appear, it should be replaced with all the candles. It should also be taken into account that in the cold season, the candles continue to work at half-capacity approximately 30-40 seconds, providing sustainable ignition in all cylinders.

Dynamic suspension fault indicator

This indicator can glow orange or red. Orange glow determines the suspension malfunction, but the car can move on average (normal) or lower suspension position. The red color indicator speaks of a serious suspension malfunction, and move on the car with maximum caution, while there is no possibility to get qualified help.

If the indicator is on orangeThis signals the fault of the suspension pneumatic system. This malfunction is considered the most common rover rover car. This may be a compressor malfunction:

• Overheat
• Weak productivity
• Short circuit winding of the electric motor

Also, the pneumatic suspension may fail the electromagnetic pneumoclipan or suspension height sensors, as well as the entire electrical wiring of the elements of the pneumatic suspension system.

If the indicator burns in redThis indicates that the system of active stabilization of Renge Rover is faulty, installed on these cars since 2013. On the model since 2013 release, a system of hydraulic cylinders is mounted, which reduce the car roll to a minimum when performing steep turns. The most common malfunctions of the hydraulic system:

• Hydraulic fluid leak from the system
• Other elements of the hydroblock of active stabilization, electromagnetic solenoids
• Accelerometer

Active car stabilizers Renge rover can leak and lose hydraulic fluid. If it is not noticed on time, failure of the hydraulic pump itself is quite possible. The most common reason for the failures of the electromagnetic solenoids is a violation of electrical wiring, and the accelerometer may refuse with frequent and fast driving on the "humpback" roads

Malfunction in the ABS system

If the indicator is not going across the engine start when all indicators are tested, or lights up when the car moves, this means a malfunction of the anti-lock system. On Renge Rover cars, ABS can be blocked due to various faults. For example, the rear differential defect can cause the abs compactance of the ABS module. The electrical wiring of the ABS sensors is often disturbed, and the sensors themselves can fail due to the broken bearing of the hub.

Active security system

If this sensor caught fire while driving, therefore, the active safety system is faulty, and as a result of airbags may not work. The causes of this malfunction may be several:

• The belt tensioner malfunction, which is also a lock where the belt is fixed. Instant belt tension, in the event of an accident, due to the triggering of a pyropatron
• Malfunction of the passenger presence sensor
• Malfunction Wiring Airbags
• Fault of the subwoofer.

Most often in the malfunction of the active safety system is to blame the wiring.

Adaptive Front Lighting System

If during the movement of the car and does not go out this indicator, it indicates either the violation of the electrical wiring, or on the malfunction of the headlight itself. The headlight in the Range Rover is unbelievable and it must be changed entirely.

Tire pressure control system

This system is one of the weak links of the car Range Rover. The principle of its work is that it removes readings from each pressure sensor, which is installed on all wheel wheels Renge Rover, including and a spare wheel. Moreover, the pressure in the spare wheel should be more normal and is 3.5-4.0 atmosphere. And if the pressure in the spare wheel turns out to be reduced to normal - the system will turn on the pressure control indicator, signaling the need to check the tire pressure. This is the algorithm of the system. In addition, in the pressure control system, a pressure sensor, which is mounted in a rolling fitting, is faced, which is generally mounted in the tire pressure control system as a whole.

To replace the pressure sensor, you must perform a tire of the entire wheel with subsequent balancing. Therefore, if you give your Renge Rover to a car service that has no specific specialization according to cars, you need to warn the masters that you do not have an ordinary fitting, but combined with a pressure sensor and requires careful circulation.

Dynamic stabilization system DSC in the early (until 2010) car models Renge Rover

If the dynamic stabilization indicator blinks while driving, this means that the DSC is working properly both when driving a car and during slipping, and if the indicator is on constantly, it signals the system malfunction. The dynamic stabilization system is implemented on the laid out program, the algorithm of which is based on the engine control system, an automatic transmission switch, automatic transmission system and other rover systems, and is designed to achieve maximum car stabilization in any conditions of the road situation.

Therefore, the inclusion of a malfunction indicator of a dynamic stabilization system is accompanied by the inclusion of other indicators indicating other faults. For example, if Renger Rover has failed an activator of the rear differential lock activator, the DSC fault indicator will constantly burn. The same happens if an anti-lock block system or an adaptive suspension system is faulty. Very often, the wiring can be the cause of any malfunction, since the car Renge Rover has enough places where the wire isolation can be collapsed and the conductor is closed to the ground. Suppose the wire is also the same.

By car Renge Rover with shock absorbers with electrical control, a dynamic stabilization fault fault indicator can light up when a cut or short circuit of control wiring. And the wires that are summed up to the upper supports of the front shock absorbers, are out of order.

Dynamic stabilization system DSC on Range Rover car models, starting in 2010

The dynamic stabilization system indicator should flash during the car movement, as this means that the system works correctly. The constant illumination of the indicator indicates a system malfunction. In modern car models, Renger Rover uses an adaptive system of dynamic stabilization. Unlike traditional systems, the adaptive system controls the machine and in standard modes using an electronic adjustable suspension in the memory of the control unit, which is stored data on various road surfaces. The system is adapted to any pavement, using the principle of "fuzzy logic". The most common malfunction of the dynamic adaptive stabilization system is the electrical wiring fault.

by phone:

First of all, I wanted to notice that the following is an overview of the most disrupted faults. This does not mean that all this will certainly happen to your car. Also, over time, perhaps some sores can be added to the list.

Basic faults Range Rover Sport (2005-2013):

Engine 5.0l, gasoline, with supercharger:

The wear of the tensioner and the calm of the timing chain. If this fault occurs, quite recently had the need to replace including the timing chains. But in accordance with the recently recently. Bulletin, the need to replace the chain disappeared.
Symptoms - extraneous noises from DV-La.
--- Supercharger fault.
Symptoms - extraneous noise from the supercharger. Repair Method - Installation of a Special Rem.Komplekt (first time I had to change the supercharger assembly, later the manufacturer was released by rem.complekt).
--- Water pump fault.
Symptoms - extraneous noise, flow pump.

Engine 4.2l, gasoline, with supercharged (supercharged):

Additional cooling system pump. As a consequence - fixation of the error in the control unit and the forced capacity limit.
--- Thermostat fault.
Symptoms - the engine does not warm up to the operating temperature or quickly cools.
--- The radiator malfunction of the heater in the cabin.

Engine 4.4l, gasoline:

Valve of the ventilation system of crankcase gases. Symptoms - smoke from the muffler, high oil consumption in the engine.
--- Lambda probes, a problem with a toxicity reduction system - only when using non-high-quality fuel.

Engine 3.6l, Turbodizel:

The crack in the nozzle / nozzles from the intercoule to the intake manifold.
Symptoms - reduction in power.
--- Malfect valve EGR.
Symptoms - dips during acceleration, power loss.
--- The fault of fuel injectors (nozzles) appears when using poor-quality fuels. Cleaning / restoring injectors is impossible, when they are malfunction only replacing new ones.
--- With long parking, the drilling of the turbine is possible. Sometimes it is possible to restore their performance without replacing the turbine.

Engine 3.0, diesel:

The shut-off valve of the USR, which is between the first and second turbine.
Symptoms when its malfunction is the loss of power, an error in pressure pressure.
- To flow the coolers of the USR. The flow can be both out (which is more often) and inside the cooler, with no inclination, but the level of antifreeze falls. During the leaks inside the antifreeze enters the turbocharger, which adversely affects its durability.
- - wear the blades of the second turbine. It is extremely rare. The causes of the occurrence are still not clear, most likely the factory defect. Repair is not possible, only replacement of the turbine.
--- The fault of fuel injectors (nozzles) appears when using non-high-quality fuel. Cleaning / restoring injectors is impossible, when they are malfunction only replacing new ones.

Malfunction ACP. In 90% of cases, it is necessary to repair the ACP itself and the hydrotransformer. In 10% of cases and automatic transmission and hydrotransformato and hydroblock (valve block).
--- IMPORTANT! The need to replace oil - every 48,000 km (against 240,000 km as prescribed earlier).

Dispensing box (RK):

Stretching the chain (mainly with very active ride).
- To flow oils from the pallet and / or electrical connector of the ACP.

Suspension and pneumatic suspension:

Compressor Montevessing (malfunction almost does not occur at a / m after 2010 g / in)
--- Body position height sensors, sensor wiring.
--- Pneumatic valves of jumper (per. / Rear).

Restricting the engine power by car Freelander 2 may occur to prevent the driver about a malfunction associated with the air supply system or fuel system. This is a general type alert and cannot accurately indicate a problem.

There are many different elements in the fuel system and the air supply system, upon failover, the same message "Power restriction" will be displayed on the instrument panel. The difference may be the behavior of the car. A warning can burn, but the total dynamics remains. The speaker can partially worse. Either the car does not gain momentum at all and does not develop power. But even this is not enough to make a sure sentence.
