File this Technical Bulletin in Repair Manual No. W42 011 294 114
The following information describe solutions for problems with noise and vibration that may occur while driving with the sunroof open.
Sunroof, servicing
Vehicles up to 08.94
Sunroof, Servicing:
Noises heard while driving with the sun roof open may be caused by some amount of adhesive -2- that has not adhered properly and is hitting against the reinforcement crossbar -B-.
The problem has been corrected in production from:
08/94 and VIN 3VWRA81H8SMO10425.
For complaints of sunroof noise in vehicles produced up to 08/94, install a pair of foam strips -1- on each side (left and right) between the metal roof -A- and the reinforcement crossbar -B-.
Foam strip dimensions:
Thickness = 4 mm (5/32 in.)
Length = 5 cm (2 in.)
Width = 2 cm (3/4 in.)
Note:
It will be necessary to remove the A-, B- and C-pillar trim panels, as well as the molded headliner -C-. See Repair Manual, Body-Exterior, Body-Interior, Repair Group 60.
Vehicles from 08.94
Noise from the sunroof heard while driving on rough roads may be caused by vibration between the sunroof trim frame and the headliner.
A new sunroof trim frame has been installed in production from 08/94.
Sunroof, Servicing:
From 09/94 production, the noise absorbers -1- on the trim frame -2- have been relocated.
During 08/94 production:
^ Dimension -a- = 106 mm (4.17 in.)
From 09.94 production:
^ Dimension -a- = 140 mm (5.51 in.)
Vehicles manufactured during 08/94 may still exhibit some noise and vibration problems. If so, the sunroof trim frame must be replaced with the later version (dimension -a- = 140 mm).
Note:
Both trim frames (during and after 08.94) carry the same Part Number: 357 877 261 O1C. The only difference is the location of the sound absorbers.
Removing
Sunroof, Removing:
- Tilt sunroof open.
- Slide headlining -1- to rear.
- Slide trim frame -2- to rear (clipped on in area of front guide -A- and
guided at rear by guide -B-).

- Remove trim frame completely, being careful to not damage molded headliner.
