51 71 215 Replacing sealing on rear left or right door

Follow REPAIR INSTRUCTIONS for bonded seals.

Necessary preliminary tasks:

IMPORTANT:

After disengaging door stop, use suitable means of preventing door from opening past its maximum permissible opening angle (risk of damaging paintwork or bodywork)
Do not touch the bonding surface and make sure it is kept perfectly clean
Do not overstretch or compress the seal when positioning it
Maximum permissible sag of seal during positioning process 30 mm
Always apply pressure perpendicular to the bonding surface to affix the seal
It is the contact pressure applied (approx. 10... 15 N/cm² ) that is decisive for a good bond, not the length of time over which pressure is maintained.
Only after being pressed on gently can the sealing be peeled off and repositioned up to three times
Disengaging the seal after it has been pressed on firmly destroys the adhesive bond.
