In the above-mentioned vehicle series, an error message may suddenly appear, signalling the failure of a light source in the rear lamps. This series has a self-diagnosis function that checks the status of the light sources after the ignition has been switched on.

The increasing use of modern driver assistance systems continually changes the challenges faced by independent workshops. Radar-based assistance systems serve as one example: while their adjustment was the concern of the respective brand workshop until recently, independent workshops with the right equipment can now also easily carry out such work. 

The engine power may be reduced in the above-mentioned vehicles, as a result of which the engine warning lamp in the instrument cluster is activated. Error code P2563 is stored in the error memory of the engine control unit.

We got that – together we are shaping the future of electromobility! With our extensive range of vehicle electronics for e-vehicles and our expertise in e-mobility, we are at your side so that you can tackle your next e-vehicle repair full of energy! 

The Active Distance Assist may fail sporadically in the above-mentioned vehicle type. This fault pattern mainly occurs in wet conditions. The entries C163AFA and C163AFB, radar sensor dirty or defective, can be stored in the error memory.

On the vehicle mentioned above, buzzing noises can be heard from the engine compartment when the air-conditioning system is switched off. These occur especially when the engine is idling.

LEDs are currently in the process of replacing classic bulbs in modern vehicles. They not only provide high luminous efficiency and increased safety, but also more design freedom and a great level of savings potential. On this page, those interested in technology can quench their thirst for knowledge regarding the basics of LED technology in vehicles.

We recommend the following procedure when replacing bulbs:

• Switch off the lighting and ignition.
• Remove the key and keep it in a safe place.
• Secure vehicle against rolling away. Apply the handbrake

How about if there were no unexpected plot twists when calibrating assistance systems? We got that! With the devices from Hella Gutmann, you'll be as smooth on the road as our colleague in the video. This makes setting up and servicing camera and radar systems super easy! 

On vehicles with Emergency Brake Assist, the error message mentioned above may suddenly appear in the instrument panel in German or English (automatic braking system fault). The message then usually appears at low speed or when the vehicle is stopped.

Starting the engine requires several attempts or is not possible at all. Furthermore, the engine may not run smoothly, there may be a lack of engine power or the engine may switch off during operation.

The lambda sensor determines the remaining oxygen content in the exhaust emission, and provides the engine control with an electric signal to control the air-fuel ratio. Scroll through this page and find out about the variants, how they work, test methods, and important information on the correct replacement of lambda sensors.
