E93 top malfunction

FLE93 · 06-21-2019, 06:43 PM

Hey Guys, I have an 08 E93 M3 and the roof is giving me a problem out of the blue. I went to put the top down and it folded up and went into the trunk as usual and the trunk lid started to close but stopped about 10 inches from closing. I cant get it up or down any further from here. If i give it a little push up it will start to work and the top will come out of the trunk and the lid will start to close but stops again 10-12 inches from closed.

The 2 salmon relays are good. Trunk is 100% empty and divider is closed. Top speed is good and fluid looks to be full. No leaks anywhere. I have lubed all the hinges also.

Switch is blinking red and a red top malfunction error on dash.

Seems like these thing have about 37 hall sensors and microswitches so narrowing this down could be a PITA!!!

I have read all the posts here and other forums also but nothing i try has worked. Any help or insight will be greatly appreciated!!

Is the car throwing any codes? Check via OBD2

Not throwing any codes. but getting 401 on the dash with the bc button, just means top is malfunctioning, No roof movement possible. If the soft hardtop is not locked.
