neallamb said:The fault appeared on my z4 when opening and closing the roof. On opening the cycle stopped when the roof package went in the boot and the boot lid failed to close. On closing the roof failed the connect with the windscreen. In both circumstances the cycle could be completed by holding down the appropriate button ( on occasion a couple of presses were necessary). So pressing the dash button appeared to serve as an override.
I therefore replaced the top hall sensor with the boot open after stopping it mid cycle. Now everything is working as it should to my relief lol
Hope this helps
Thanks it did help. I managed to get the new sensor fitted at the weekend, although I had to cut off the old connector and reuse that in the end (plus wait for a smaller sized crimping tool to arrive). Annoyingly it hasn't fixed my issue though so I'm a bit stumped!

I replaced the hall sensor with the longer lead on the top of the boot piston, and yet with both the old sensor and the new sensor I still get the same error "A696 open circuit, closing movement".
I tested the new sensor using a multimeter and it's working correctly, I also tried reversing the brown & red wires as they appeared to be opposite on the replacement, and if I disconnect the sensor I get a different error "A696 open circuit, closing movement, short circuit to negative".
So I guess the fault is on that cable somewhere, but probably out of my reach?
