optimal sunroof operation, regular lubrication maintenance must be
performed.
Production Solution
A slightly greater amount of lubricant is used.

2. The cleaning and lubrication of the rails will be done with the VAS 6621 and the VAG 1628.
Cleaning The Guide Rails
1. The bulk of the old lubricant, dirt and debris will be removed as follows: Insert the VAS 6621 to the rear of the guide rail (Figure 22, 1), turn
it 90锟斤拷 (Figure 22, 2) and slide it toward the front (Figure 22, 3). Turn the tool 90锟斤拷 once again and remove it (Figure 22, 4-5). Clean the old
lubricant and debris from the tool. Repeat this procedure starting from the front of the guide rail and slide the tool toward the rear. Perform
this procedure to both sides.
2. Remove any remaining old lubricant, dirt and debris using a lint-free cloth. Using a vacuum cleaner may aid in removing any sand, grit or
other abrasive materials that would damage the sunroof mechanism.
Lubrication of Guide Rails:
144
1. Thread the VAS 6621 tool onto the lubricant canister (G 060 751 A2). Install the assembly into the VAG 1628.
145
2. Insert the VAS 6621 into the guide rails in the same way as the cleaning procedure and inject the lubricant evenly along the guide rails.
Perform this along the entire length of the guide rails and to both sides.
Cleaning and Lubrication of the Lid Mechanism of the Front and Rear Lids:
1. Move both the front and rear sunroof panels to the vent position. Remove the old lubricant, grit and debris using a lint-free cloth.
Tip: Cover the interior of the vehicle to protect against falling debris.
146
2. Spray lubricating paste G 060 751 A3 on the mechanism for the front and rear sunroof panels at the areas indicated by the arrows in the
illustration.
3. Clean and lubricate the guide plates of the front and rear sunroof panels. It will be necessary to press down on the lip of the rubber seal to
expose the guide plates. Lubricate the guide plates with G 060 751 A3. Make sure the lubricant fully penetrates the rollers.
4. Spray lubricant G 060 751 A3 along the mechanism of the rear sunroof panel (Audi Q7) as shown in Figure 28.
Cleaning and lubrication of the slides of the front sunroof panel:
147
1. Clean the slides with a lint-free cloth. Apply lubricant G 060 751 A2 to the slides with a brush to both slides.
Cleaning and lubrication of the seals:
1. Clean all the seals with all-purpose cleaner D 009 401 04 and a lint-free cloth.
2. Lubricate all the seals with special lubricating paste G 052 141 A2 using a brush.
Tip: No parts have to be removed. It is only necessary to completely open the sunroof panel.
148
3. Another source of noise can come from the sunroof panel trim. Make certain that all of the sunroof trim is intact and correctly installed.
149
4. Incorrectly installed, or incorrectly adjusted sunroof panels, cause tension and are another source of noise. Check and adjust as necessary
using ElsaWeb or refer to TSB 2018898.
5. A loose wind deflector mounting can be a source of noise as well. Refer to TSB 2012804.
A6/A8
A6/A8:
1. Lubricate the seals with special lubricating paste G 052 141 A2.
Tip: No parts have to be removed. It is only necessary to completely open the sunroof panel.
2. Lubricate the mechanism components with lubricating paste G 060 751 A2.
150
3. After application of the appropriate lubricant to the indicated areas is complete, open and close the sunroof completely 2 to 3 times to
adequately distribute the lubricant.
