32 13 070 Removing and installing electric steering box (EPS)
Attention !
Steering box :
Check connection of steering box for corrosion, clean contacts if necessary. STEERING GEAR MUST BE REPLACED if the corrosion is too far advanced.
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.
Attention !
The torsion bar of the steering gear must not under any circumstances strike other components!
Collision with other components may result in damage to the steering box!
Do not turn the steering wheel once the steering shaft has been detached from the steering box/steering column! If the lower section of the steering shaft is separated from the steering gear/steering column, the steering column switch cluster (SZL) may be damaged when the steering wheel is twisted!
