32 13 572 Replace electrical steering box (EPS)

IMPORTANT: Connecting line:
In the event of moisture/corrosion inside the two plug connections, check the insulation of the connecting line. If the insulation reveals any noticeable/striking features, partial replacement will be necessary. Otherwise it will be sufficient to replace the contacts or connector housing.

NOTE: In a warranty case you must always provide a fault memory printout, even where there is no fault entry, with the defective part.

IMPORTANT: Do not turn the steering wheel once the steering shaft has been detached from the steering box/steering column!
