SUBJECT
Wear Marks on the C-pillar Area of the Soft Top Canvas
MODEL
E88 (1 Series Convertible) produced to 10/2009
SITUATION
Wear marks may form on the soft top cover in the C-pillar area, above or below the canvas seam and or along the seam. These wear marks may be
visible on one or both sides and are generally less than 4mm in diameter. They are first visible as a smooth spot on the cover, and progress to a white
mark. In severe cases, a hole could form in the cover material.
CAUSE
1. Improper limit spacing between the soft top cover and the soft top frame when folded in the fully open position
2. The seal carrier contacting and wearing the canvas top cover and
threads
3. Tension straps and main bump stops out of adjustment.
CORRECTION
Verify that all three updates are installed, and perform those which have not been carried out. Only replace the soft top if there is physical damage.
1. Install a new limit spacer kit.
2. Modify the lower portion on the seal carriers.
3. Install the soft top repair kit, modify the tension strap, and adjust both left and right main bump stop limits.
