My convertible top stopped part way down. Using the owner's manual I was able to manually close it and get home. The top was totally inoperable - just flashing red lights. After doing some searching, I decided to order the Bavarian Technic's code reader. It worked great except for one problem, the CVM fault code was 165 - undefined error Now what???? Did a google search and found this thread. Went out and checked continuity of the sensors and discovered 2 sensors were disconnected. Cut into the wire harness as noted in the previous post and found 2 broken wires. 2 pieces of wire and some solder fixed the problem.

Thanks for saving me at least $1K at the local dealer.
