Procedures
A. Rubbing noises in the area of the right side of the windshield
Models 164.175/186 up to VIN A074262
Rubbing noises occur on the instrument panel in the area of the right side of the windshield due to the instrument panel contacting the crossmember under the windshield.

B. Creaking noises in the area of the instrument panel near the A-pillar
Models 164.175/186 up to VIN A104410
Creaking noises in the area of the instrument panel near the A-pillar occur due to the crossmember under the instrument panel contacting the heavy-duty foil on the inside of the A-pillar.
