Ideal setting, preload:

NOTE: Pre-tension can be checked with or without weather strip. Pretension is 1.0 mm greater with weather strip. Magnet in special tool 51 0 341 creates the correct door window glass pre-tension on the seal system for measurement. No force must be exerted on the door or door window glass during measurement.

Insert special tool 51 0 341 in rotary striker of door lock and close rotary striker manually. Carefully close door.
