How many times has a Webasto heater rescued you in difficult weather conditions? Caring for your family in summer and winter, now is the time for you to take care of him.

"Our company" carries out repairs and maintenance prestarting heaters Webasto. We will help you avoid costly replacement, we will repair the heater installed on the car, and removed from the car.

Let's start inspection ...

Comprehensive diagnostics will help you get a complete picture of the condition of your Webasto pre-heater:

  • technical condition of the working heater;
  • search for the causes of malfunctions in the idle "Webasto".

Only after a thorough research and scrupulous diagnostics, our employees will proceed to repair. At the same time, we will not reanimate the equipment, which is expedient and cost-effective to replace with a new one.

Types of faults

After several seasons of active use of the Webasto heater, malfunctions may occur such as:

  • self-shutdown;
  • auto-lock;
  • muffler breakage;
  • boiler breakdown;
  • failure of the timer;
  • lack of remote communication;
  • problems with the AO control unit;
  • and other.

Without proper care and regular cleaning, fail:

  • the combustion chamber;
  • glow plugs;
  • flame sensor;
  • water pump;
  • fuel pump.

The combustion chamber is often clogged with soot and must be cleaned periodically. special means for removing carbon deposits.

Whatever happens to your equipment, a minor breakdown or a major problem requiring extensive repairs, we can handle it. Being official dealer Webasto company has at our disposal not only original spare parts, but also a knowledge base and experience in repairing heaters.

At the time of the renovation works you do not need to leave your car with us. Employees dismantle the heater, loop the vehicle's cooling system, isolate all connectors, and plug the fuel pipe.

Thus, you can continue to operate your car while we repair your Webasto. Indeed, depending on the complexity of the breakdown, it may take from 2 days to 1 week.

Before installing the repaired heater, our specialists will perform a test run at the diagnostic stand. Its successful completion allows us to install a heater on the car, guaranteeing you a long service life of the device.

Helpful advice

The manufacturer recommends that the pre-heaters be diagnosed twice a year: before and after the winter season. The combustion chamber must be cleaned regularly. The air duct must be checked for leaks and the electrical contacts for corrosion.

Many of us have asked a similar question, but not all have found the answer. Next, let's try to sort out the main errors in configuring the adapter and subsequent diagnostics.

First, we need to connect the adapter to the PC to install the drivers. As for modern operating systems, drivers will be installed automatically after connection, if this does not happen, we install it manually. You can download drivers on the website on the "Documentation" page in the "" section.

A dialog box confirming successful installation should look something like this.


We don't need to change anything here. Let's even try to break the myth about port speed, which many are trying to change. I will configure the port speed of the adapter and PC myself in automatic mode, regardless of the values \u200b\u200bthat are specified in the properties.

Now let's move on to the most important thing. Click "Advanced" and the following menu will open to our eyes:


COM port number - here it is important to set COM1 or COM2. If you have these ports busy, then if possible, we recommend reconfiguring the equipment using them to other subsequent ports.

Now you can sequentially close open windows and, if the system asks, restart the PC. Although I would have performed a forced reboot anyway, so to speak for the "purity of the experiment".

We figured out the settings and now let's move on to the diagnostic process. To begin with, do not forget to indicate in the diagnostic program on which port your adapter is connected.

Rule number 1 - for some adapters, you must first connect the power supply, and then connect the USB cable to the computer.

Rule # 2 - applies to current and previous Webasto water heaters.

Diagnostics of analog heaters is carried out by pin No. 2.

Diagnostics of digital heaters can be carried out by pin No. 1 or by pin No. 2, depending on the ECU model (electronic control unit or control board)

There may be exceptions to this, as in any other rule, so if the heater does not go to diagnostics, and you are not sure which ECU it has, it will not be superfluous to try to connect to another pin. Also, if there is no confidence in the ECU, it is recommended to connect in automatic mode, but this does not always work correctly.

Rule No. 3 - applies when sequentially diagnosing analog and digital ECUs with some adapters or when errors occur, for example:

In this case, close and reopen the diagnostic program without fear. This operation can save you time and hassle.

Thank you for attention. I hope that this brief instruction will be useful to someone ...

The cold is just around the corner! Summer will come only a year later and this suggests that you need to properly prepare your car, and in particular, check the operation of autonomous heaters and heaters.

Usually, if you are a truck driver, you have probably already visited under a sleeping bag or opened the storage compartment in order to make sure that it is ready autonomous system... But even full set and the presence of fuel does not guarantee a safe start of the system. And therefore, you reach for the control panel, and in response you see only a light signal indicating an error.

After what you have seen, if you have experience in working with such installations, armed with a tool, you can independently audit the unit. If you are a simple car owner with no experience in handling Webasto pre-heaters, you should trust the experts.

How is the diagnosis done by professionals?

The pre-heater specialists perform diagnostics as follows:

  • Connect the original diagnostic equipment
  • Read and decode error codes
  • Check if errors are cleared
  • Test run of all components
  • The entire heater is started
  • Visually inspect the heater itself, wiring, fuel line, fuel pump, fluid pump, control
  • Remove the heater (if required)
  • Clean the mesh, the heater itself, the combustion chamber (if required)
  • Replace the heater component (if required)

After a visual check, the diagnostics move to the level of mechanical study, either by using a conventional multimeter. It is worth noting that modern manufacturers have taken care of creating their own diagnostic device for their brand.

Professional diagnostic equipment is able, without removing the heater, by connecting to determine all the problems that can only arise with autonomous heaters, namely, what requires repair, and what is completely replacement.

Specialized equipment allows you to determine the internal problem as accurately as possible, as well as the stage at which internal failures and accidents could occur. By contacting a special technical (installation) service, you will receive full information about all kinds of warnings and already possible problems.

Timely contacting the masters will help both to prepare the pre-heater for the season and to identify existing problems. Ultimately, a diagnosed and repaired device on time will definitely not let you down at the most inopportune moment for this.

Repair of prestarting heaters, Webasto heaters

After thorough diagnostics on special, professional equipment, it is possible to accurately determine all kinds of risks and existing problems, from serious to the most insignificant, and then immediately proceed to repairing Webasto heaters.

Repair should be carried out by a specialist in order not to damage the structure even more. Self-intervention in the heater system can lead to a complete failure and subsequent more global intervention of the masters. In this case, the most budgetary and reliable way is the preparation, diagnostics and repair of Webasto by professionals.

Let's consider the manufacturing process of the simplest diagnostic adapter for Webasto diagnostics. To do this, we take an inexpensive but reliable and time-tested VAG COM adapter.

You will also need additional materials:
* 3 wires about 1.5 meters long;
* 2 clips crocodile;
* 1 terminal male;
* 1 female terminal;
* terminal housings (female-male).

Let's see the pinout of the ODB2 connector. We are interested in 3 contacts, "ground", "+12" and "K-Line". These are 4, 7 and 16 pins. We need to solder wires to them.

Now, we take and disassemble our adapter, disassemble it by unscrewing 4 screws

We solder the wires to the above contacts.

Crocodiles: red plus, black earth, mom (or dad) and a body for him for "k-line".

As a result, we have

Let's consider the connection to Webasto using the example of Webasto Thermo Top C diesel Analog.

Remove connector X1, 6-pin on the boiler

The 2nd contact is responsible for the diagnosis, and we attach the wiring with the dad and the body to it.

After carrying out these simple manipulations, we need to download the Webasto Thermo Test program and install it on the laptop.

When everything is ready, we connect our homemade tester. It is important to realize that the connection sequence matters.

We connect the "k-line" wire to the boiler. Then, we connect the adapter power, i.e. crocodiles to mass and + 12V.

and only then is the USB connector to the laptop.

We start the program, select our boiler from the list. We check that the program sees it and shows us its errors, etc.

You can buy the VAG COM adapter in our store.

In such cases, you will need to seek help from a private specialist who will repair the components and fully carry out diagnosticsat webasto... When a problem occurs with a car's electrical system in a huge city, it causes serious discomfort for the driver. If you urgently need to rush to work, and the air conditioner or heater does not work in the car, this can cause a lot of inconvenience.

Webasto diagnostics - the solution to all problems

It's no secret that the heating system and air conditioning are directly related to electronic unit management. Since you have to deal with an electrician, you need to seek help from auto electricianwho has sufficient experience with such elements.

It is convenient that today the driver does not need to drive the car to the car service to cope with the repair. Constant queues, poor quality support, as a result, the air conditioner stops working again after a while, and all this is nerves and money. To prevent all this from happening, you need to contact exactly the person who is ready to come on their own and do everything on the spot.

Diagnostics of Webasto components is understood as a number of processes that are carried out in order to clarify data on the current state of an electronic device. Thus, the master immediately sees with which components there was a problem. Often, drivers do not know all this, therefore they are at a loss.

The whole process is more automated, all information is displayed on the screen. As a result, the master is provided with information about which parts need to be replaced. Previously, it was difficult to find a good master to repair an air conditioner or stove. Today it is more than real.

Next stage -repair webasto

The repair phase begins immediately after the diagnosis. In general, the whole process from the beginning to the end of the arrival is as follows:

  • preliminary diagnostics are performed;

  • renovation is in progress;

  • the operability of the device is checked.

At the second stage, when the master knows what the actual problem is, the components are replaced or repaired. This process is quite simple, since the specialist has been dealing with this for more than a year. Very often the problem occurs in the purchased used cars. The buyer rarely thinks about the stove when buying, or rather, how long it will last.

Recommends a preliminary webasto diagnosticsbefore buying, since German components have quite high cost... In addition, during the diagnosis, you can notice the reason for the failure and eliminate it. At the last stage, immediately after the repair, diagnostics are carried out again to check the operability of the components. All this is done quickly and efficiently in just one visit!
