Supersedes Technical Service Bulletin Group 57 number 12 - 71 dated September 17, 2012 for reasons listed below.
Affected Vehicles
Condition
21
The outer door seals have become partially detached.
Technical Background
Loss of adhesion between the door structure and door seal due to a flaw in the attachment process in production.
Production Solution
Optimized production process.
Service
In cases where the outer door seal has become partially detached, it may not be necessary to replace the outer door seal. Seals can be reattached
provided they are not damaged, have not been previously repaired or previously reattached and the detachment length does not exceed 10 cm.
1. Inspect all four doors.
^ All undamaged, previously unrepaired, or loose seals with a detachment length less than 10 cm will be repaired. Complete steps 2-9 below
to repair the door seals.
^ If the door seal is damaged, has been previously repaired, or previously reattached or detached greater than 10 cm, replace the door seal
according to the repair instructions in ElsaWeb >> Body >> Body Exterior >> 57 Front Doors, Central Locking System >> Removal and
Installation >> Doors >> Door Seals. In the case of a rear door seal replacement, refer to ElsaWeb >> Body >> Body Exterior >> 58 Rear
Doors >> Removal and Installation >> Rear Door >> Door Seals.
Note:
In addition to the repair manual instructions for replacing the door seals observe the following: Thoroughly clean the area of seal
attachment with plastic cleaner D 00940104. Allow the area of seal attachment to dry completely (at least 5 minutes). Apply bonding agent
D 355205A2 using a D 00950025 applicator to the seal attachment area. Allow to dry an additional 5 minutes.
If repairing the door seals, proceed as follows:
2. Ensure that the temperature of the door and outer door seal are not cooler than 70锟斤拷F (21锟斤拷C). This is vital to ensure optimum adhesion of the
outer door seal.
3. Thoroughly clean the bonding surfaces of the doors to be repaired with plastic cleaner D 00940104. Allow the bonding surfaces to dry
completely (at least 5 minutes). The bonding surfaces must be dry and free of any dust, grease, silicone or any other similar contaminant that
might compromise the adhesion.
4. Apply bonding agent D 355205A2 using a D 00950025 applicator in the area to be bonded. Allow the treated surface to dry an additional 5
minutes.
5. Thinly coat the outer door seal with rubber profile adhesive D 477KD1A2 in the area that has become detached.
22
6. Press the door seal lightly to the door surface and then detach it again (Figure 2). This ensures that the glue is distributed as evenly as possible
on the surfaces to be bonded.
7. Allow the now detached area to dry for 5 minutes.
8. After this time attach the seal firmly to the door surface. Roll over this area several times with special tool 3356 (or equivalent).
23
9. Apply force to the seal with the 3356 only at the base of the seal (area 3 shown in Figure 4).
10. Remove any residual adhesive that may be visible with adhesive remover D 002000A2.
Tip: The repaired door should not be closed for two hours. During this time, any freshly glued surfaces should not be tested by pulling on the
seal to see if they have bonded.
