  Note!
   
If the cause of the fault cannot be found for repairing it, continue to look in the faults memory in the control unit for the engine electronics and in the control unit for the automatic gearbox. When doing so, do not forget to take into account that the high pressure transmitter -G65- is also called, mistakenly, manual pressure switch for the air-conditioning -F129-.
