Condition
The roof channel trim on either side of the Open Sky Roof is loose. Typically the trim is lifting in the rear. In some cases, the trim has lifted high
enough that it comes in contact with the rear lid when the rear lid is opened. The trim can then be forced forward, causing damage to the trim, rear
lid, etc.
Technical Background
Too few roof channel mounting clips.
Production Solution
The rearmost clip will now be riveted to the rear panel.

1. Before repair it is important that the vehicle and any replacement parts be at room temperature (approximately 20��C or 68��F). Bring the vehicle
into the workshop to warm if necessary.
2. Even if only one side is detached, make certain to repair both moldings. Inspect for any consequential damage. If any damage is found, this is to
be repaired at the time this repair is performed. If the roof channel moldings are undamaged, they will be reused.
3. With the liftgate open, use a plastic hobby tool to carefully detach the molding from the clips by starting from the rear of the molding. Detach just
the first clip on each side.

1. Close the liftgate.


2. Complete the removal of the roof moldings by detaching the remaining clips.

6. The original number, type and position of each clip installed may vary. The diagram shows the correct type, position and quantity of each clip.
The rearmost clip that will be installed (8P4 853 573C) will have a hole to accommodate the rivet.
With the molding removed, check for clips that may be loose, of incorrect type, in an incorrect position, or damaged.
7. Remove any loose or incorrect clips and clean away the residual adhesive pad.

8. Mark the location where a 4 mm hole will be drilled into the flange of the rear cover panel. It will be located 35 mm from the rear edge of the
flange.
9. Position a 8P4 853 573C clip, centering the mark with the centerline of the hole. Move the clip into its installed position laterally. Mark this
position with a punch.
10. Prepare a 4 mm drill bit and mark the bit in a way that allows the bit to penetrate no more than 9 mm.
Note:
The bit must not contact the roof panel beneath the rear cover panel. This will damage the corrosion protection in the roof panel. Drill the hole
through only the panel flange.

14. Bond the clip. Make certain holes align. Apply a small amount of window bonder DH 009 100 A2 inside the hole. Rivet the clip using rivet
WHT 004 964.
15. Apply cavity wax D 308 SP5 A1 to the top and bottom of the rivet.

1. Prepare the surfaces where new clips may need to be installed by removing the residual tape and cleaning with D 009 401 04 cleaning solution.


2. . After the surfaces are cleaned, wipe the contact surface inside the channel with 3M(R) Automotive Adhesion Promoter (product number 06396).
