Car carpet and floor mats can then become quite wet. Water can also get into the interior fan, which leads to loud, squeaky noises being emitted from the fan.

If the above vehicle model experiences engine starting difficulties regardless of the temperature, one possible cause may be a defective intake manifold pressure sensor.

The knock sensor monitors the combustion process in the engine. Its signal helps the engine control to prevent knocking combustion and therefore protect the motor/engine control. On this page we will provide you with various information, including how a defective knock sensor becomes noticeable, the causes that may lead to its failure, and how it can be tested in the workshop.

The ABS/ESP warning lamp may light up sporadically on the above-mentioned vehicle series. After a restart, the warning lamp initially goes out again, but is reactivated after a short driving time.

Is the fault diagnosis not working at all? We got that. With flexible and automatic diagnostic solutions such as mega macs X, you can crack even the toughest nut on the car lift – without breaking out in a cold sweat or having your heart race.

The DSC warning lamp on the above-mentioned vehicle series has been known to light up sporadically. In addition, various Check Control messages can be displayed in the instrument cluster.
