On the above-mentioned vehicle with an AFS headlamp system, the failure control lamp may all of a sudden come on. AFS (adaptive front lighting system) is a lighting system that uses movable lenses to adapt to the road conditions, the weather and to the speed situation.
On the vehicle mentioned above, it is possible that the ABS/ESP control lamp suddenly lights up. Often the error code C1606 (ECU/software error) is then stored in the control unit. A possible cause is "a software weakness" in the control unit of the front camera.
If headlamps or other vehicle lamps are fogged up on the inside, car drivers usually consider this to be a defect. However, in some cases this is a physical phenomenon. This page explains how this can come about. You will also find out what to do if water collects in the headlamp or other vehicle lamps. There is also a step-by-step guide for replacing faulty lamps, which provides a number of practical tips.
Failure of various systems in connection with problems on the multifunction steering wheel
With the above-mentioned vehicle, various failures/malfunctions (cruise control, gear selector) may occur in conjunction with the multifunction steering wheel. The error message "cruise control failed" may then appear in the instrument cluster.
Upon identifying a steady coolant loss in the above-mentioned vehicles, check all coolant hose connections and the radiators for leaks. We recommend pressurising the cooling system with a suitable tool according to the manufacturer's specifications.
If the headlamps on this vehicle are permanently on and / or it is not possible to switch between low and high beam, the cause could be a faulty multifunction switch. In addition, the error may be stored in the control unit.
Injection valves provide each cylinder with the required fuel and simultaneously atomise the fuel so that it can burn most effectively in the combustion chamber. Scroll through this page and find out how injection valves work and potential fault symptoms. You will also find useful tips for performing troubleshooting work on injection valves with the engine running and switched off.
Discharging of 12 V battery for the vehicle electrical system
If the above-mentioned defect is detected, it may be related to a problem with the keyless central locking system. Because of water ingress and corrosion affecting the door handle switches, the receiver detects an opening request and sends this signal to the body control unit.
On the above-mentioned vehicle with a start-stop system, the engine control lamp may suddenly come on. At the same time, there may be a drop in engine performance. Error codes P0300 / P301 / P302 / P0303 / P0304 (cylinders 1-4 misfiring) may be stored in the control unit.
The rain sensor is a driver assistance system which takes the strain off the driver by automatically activating the windshield wiper system when it rains and thereby significantly improving in-vehicle safety and comfort. In the mid-1990s, the rain sensor started to be fitted in vehicles and since then has been a permanent feature of modern vehicle electronics.
If the error message "SCBS / City emergency stop assistant forward gear malfunction" is displayed on the instrument cluster on the vehicle models mentioned above, one cause for this may be a defective boost pressure sensor.
