CONTACT CORROSION
Contact corrosion can occur if incorrect fasteners (bolts, nuts, washers, etc.) are used.
For this reason, only fasteners with a special surface coating are used.
In addition, rubber or plastic parts and adhesive consist of non-conductive materials.
If there are doubts as to whether parts are suitable or not, use new parts.
Note. We only recommend original replacement parts, they have been tested and are compatible with aluminum. We recommend using Audi accessories. Damage resulting from contact corrosion is not covered by warranty.
WINDSHIELD WIPERS, BRINGING INTO SERVICE POSITION

WINDSHIELD WIPER ARMS, ADJUSTING
Procedure
Note. If the windshield wiper motor is to be run during the work procedure, the hood must be closed, otherwise the voltage supply of the wiper motor will be interrupted.
Remove wiper arms, refer to WINDSHIELD WIPER ARMS .
Switch on ignition.
Activate one-touch wiping and let wiper motor run in end position.
Note. Every second time the wiper motor is switched off, it returns the wiper arms to a slightly upper rest position, thus tipping the wiper blade lips the other way. The wiper motor will run all the way down to the end position and then a bit up again. This upper rest position must not be used to adjust the wiper crank. Only use end position where wiper arms run directly end position with no overstroke. Activate one-touch wiping again if necessary.
Turn off the ignition.
Position wiper arm with wiper blade installed at wiper axle and align wiper blade at windshield as follows
Scheme 39
- Dimension -a- = 0 to 10 mm.
- Dimension -b- = 0 to 10 mm.
Note. The dimensions indicate the gap between the wiper blades to cowl panel of plenum chamber at lower edge of windshield.
