Cause Mounting clips broken or not correctly engaged. Remedy Replace all mounting clips with collar nuts with shims (picture 2): Adapter set (203 589 02 31 00) is required to perform the work. The underfloor paneling does not have to be removed. 1. Loosen all mounting clips. Use a 13 mm socket for this (picture 3). 2. Unscrew all mounting clips. • During spraying, the underfloor paneling must be pressed upwards against the vehicle underfloor. 4. Install a spacer washer on each threaded pin between underbody and underbody paneling. • Each time, carefully lift the underfloor paneling from the underfloor (picture 5). • During installation, ensure that the side with the engagement lobes points downwards. • After installation, the spacer washer must be in full contact with the underfloor (picture 6). Information: The spacer washers prevent the underbody paneling from coming into contact with the vehicle underbody, thus preventing possible corrosion effects 5. Install collar nuts.
