IMPORTANT: Steering gear:

Check connection of steering gear for corrosion, clean contacts if necessary. The steering gear must be replaced if the corrosion is too far advanced.

Connecting cable:

In the event of moisture/corrosion inside the two plug connections, check the insulation of the connecting cable. If the insulation reveals any noticeable/striking features, it will be necessary to replace the part. Otherwise it will be sufficient to replace the contacts or plug housing.
