I've been puzzled for a few months about my roll bar. I have the roll bar idiot dash light lit and the roll bar switch blinks when the bar is down. I've had BBA Reman rebuild the soft top controller ($390) behind the passenger's seat but that did nothing to change these symptoms.
It all started when I asked my upholsterer to recover the convertible top lid and recover the roll bar. He took the roll bar off and recovered it with original MB vinyl. Now these items look great but I got roll bar fault issues when he completed the work.
I searched the forums (http://www.benzworld.org/forums/r129-sl-class/1324795-r129-roadster-soft-top-electrical-controller.html) and several of the posts said my symptoms indicate the soft top controller MY '90, PN 129 820 0097, is faulty. I had my upholsterer pay for the rebuild but after reinstallation it still has the same fault. The fuse in the trunk was also blown when I got the car back and the seat belt retractors would not operate properly until I installed a new fuse. That is fine now.
The top goes up and down properly except the roll bar will come up before completing the cycle (either up or down)...the logic knows there's a fault in the automatic roll bar deployment system somewhere and it wants to ensure the vehicle is safe.
Where to check next? Any suggestions?
