If the performance of the air-conditioning system is inadequate when outside temperatures are high, a faulty evaporator temperature sensor (see illustration example) may be the cause. Incorrectly measured values can cause the evaporator to freeze and block the air flow.

If the fault mentioned above is detected, it may be in connection with the triggering of the fuel cut-off switch. A fuel cut-off switch is installed in this vehicle. The switch is triggered in the event of a sudden change in the vehicle's position and if any strong vibrations occur.

The following problem is observed on the vehicles mentioned above. During navigation, the display may malfunction (e.g. delayed image display).

The primary task of the exhaust system is conducting the combustion gases of the engine past the driver's cab into the open air. Noise caused by combustion is reduced to the permissible volume by integrated mufflers. 

If the engine of the above-mentioned vehicle only starts after the starter motor has been operated for a longer period of time, a faulty crankshaft sensor may be responsible for this. Crankshaft sensors are used to determine the speed and crankshaft position.

In the above-mentioned vehicles, incorrectly routed condensation water drain hoses of the air-conditioning system can cause a variety of electronic problems.

In the case of the above-mentioned vehicles, there can be a reduction of engine performance. The error codes P0010/P0016/P0088/P0341 are often stored in the error memory. These refer to the variable valve control or to the crankshaft/camshaft position.

The high beam optimally lights up the road in the dark. However, this light function is only used rarely so as not to dazzle oncoming road users or vehicles in front. Camera-based high-beam assistants solve this problem. 

In the case of the above-mentioned vehicle, the hybrid system, during sudden acceleration, may switch off abruptly instead of switching to emergency mode. During excessive acceleration, there may be temporary slip in the input attenuation of the hybrid transmission.

On the above-mentioned vehicles, the control lamp, which signals the failure of a bulb (light bulb) may suddenly light up. A visual inspection of the lighting equipment on the vehicle, however, does not reveal any defect.

In the above-mentioned vehicles, it may be possible that the engine starts poorly or not at all. The engine control lamp and/or the preheater control lamp will light up in this process. An engine power loss can be observed at the same time. Fault codes P062B and 20EE may be stored in the fault memory.

During an engine's combustion cycle, the rotary movement of the crankshaft is sped up and slowed down This rotational irregularity is transferred to the accessory drive as a result of the alternator's moment of inertia.
