Vehicle system and function
Control unit of the Servotronic, the speed-sensitive power steering: it actuates the electric valve on the steering box. When maneuvering there is full steering assistance; as speed increases, it is reduced – it is never switched off completely.
Installation location: Audi A8 D2: relay carrier in the electronics box in the front passenger footwell, slot 12 (Servotronic control unit).
Condition: Used genuine part with normal signs of use on the housing (ZF SERVOTRONIC, 7038 900 207, barcode label). Six blade terminals; the sticker with the number 356 is slightly wavy and dirty.
How to recognize a defective part
  • ● Steering unusually heavy at slow speeds and when parking
