My top is now working. I had did the rotational sensor mount mod to elongate 2 of the 3 mounting holes but my "conv top not locked" message was still there. I read on this or another 645Ci convertible forum topic that you could use your key from outside your car to open close the top. This worked, I used the allen crank to slightly open the top and then used the key to complete the operation and my top went down and the "Convertible Top Not Locked" message and dreaded 5mph chime are all gone.
Now since I am not under warranty. Do I leave me car in the garage with the top open and only bring it out on nice cloudless days or do I use it and see how long this fix lasts. What a piece of crappola this top is for such a nice car.
Again, I recommend to all person considering the 2004 to 2007 (at Least) BMW 645 TO BUY the coupe. Stay away from this LEMON top.
Thanks for everyones help getting my car fixed (at least temporarily).
