BMW convertible hoods operate via swing arms; the arms retract the hood once a latch disengages the hood’s U-attachment point. Electrical and mechanical problems might occur during this process. Issues can often be resolved via some basic troubleshooting techniques.
The sensors of a BMW convertible lower the top and check for obstructions that might impede hood operation. Window sensors sometimes indicate a window is in the up position, even if its rolled down. This prevents the top from lowering.
The wiring for the trunk lock on the BMW convertible connects to the wiring of the top's system. A faulty trunk lock occasionally renders the trunk lid inoperable if the top remains open; the top may not lower while the trunk is open. Replace the bad trunk lock to solve the wiring issue.
The swing arms that rotate the hood must be in alignment when retracting and closing the top. Broken arms cause improper opening and closing of the hood; they create uneven hood gaps between the front body and hood panels. Defective swing arms must be replaced.
