i just wanna share my case, it could help to somebody with that problem.

suddenly, the roof of my z stop to work, then i began t use it manually.

in the weekend i decided to troubleshoot the system to find out root cause.


i checked fuse box, i checked fluid lines, and finally checked the motor in a stand alone mode, and it works.

then i went to the electrical troubleshooting guide and i was noticed of a "close roof sensor", that could make the system fail.

i did the "sensor" cable check and realize a cutted zone near the hydraulic piston.

all indicates the roof metal "bites" the cable ocasionally until if gets damaged.

i hope this coould help another budy with roof problems.

Thats why i just dont mess with convt's

aww, come on. you haven't felt the joys of timing an E36 convertible top?
