The customer complains about white impressions on the convertible cover. The impressions are located exclusively in the area of the left-hand main bearing.
Possible cause is incorrect cable routing to the auxiliary brake light. The cable can be jammed on lowering the convertible top and cause impressions.
Check the cable routing to the auxiliary brake light and adjust if necessary. See Fig. 1.
Impressions in this area can be removed using a dry and clean hand brush.

The cable must be guided through the V-shaped cutout of the tensioning bracket holder.
