Complaint:
Underfloor paneling is loose or sags (picture 1).
Attachments
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.
3. Treat all threaded pins with wax (picture 4). During spraying the underfloor paneling has to be pressed upwards against the vehicle's underfloor.
4. Install a spacer washer on every threaded pin between underfloor and underfloor 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).
Note:
The spacer washers prevent the underfloor paneling from touching the vehicle underfloor and thus prevent possible corrosion effects
5. Install collar nuts.
Note:
The threaded pin does not protrude out of the collar nut due to its length (picture 7).
