So having suffered the folding roof dramas of wont go up, down, drops the windows and locks them over that last month. I did my bit of research and shelled out for a Foxwell510Elite.
What a piece of kit, though significantly more expensive that the system i use on my VW&audis.
As suggested elsewhere you can look at the individual sensors and read their current state all through the operation. On selecting the channels before even operating I could see that for some reason the rear end module closed, left and right sensors were not reading the same. (see pic).
On opening the roof, part way through the cycle they read the same and the roof worked perfectly after that all the way down and back up again. Once again the roof was performing corrrectly, shortly after it errored again and went back to its original different reading.
I stripped out the rear trim and got to the sensor wiring and checked that for continuity from the ecu plug and all was well. So that either leaves the microswitch or the ecu. I get the new microswitch from BMW later today (£18) and will install tonight and report back.
