Why would you downgrade CAS with working key available?!
Went to a 2009 3 series BMW to do a spare key. All doors were opening-locking on old remote. Downgraded security software and programmed new remote.
Car starts and opens-locks all doors apart from drivers door. Both remotes old and new not working with drivers door ?
AVDI was used
Anyone seen this happening before ?
Thank 👍🏻

Guided fault finding = Feature that many factory scan-tools have and real technician despise it.
Probably just a broken locking actuator on driverside door try to activate actuator in inpa i believe its under body and then central locking but cant remember exact procedure.

Just bad luck that the actuator went at the same time as you worked on the keys. I get it all the time, " Ever since you made me a new key, the handbrake squeaks."

It was downgraded because it was CAS3 ISTA Done OBD with full battery support
Ran diagnostics saying footwell module fault
Drivers window never worked so don’t know if connected to this problem ?
upgrade cas with avdi or icom

If the FRM is gone Yanhua does a brilliant wee add-on to fix it.

I’ll try upgrading CAS
Thanks everyone 👍🏻
I've been out to one where nothing would work on the drivers door, turns out to be water ingress in the FRM module, water leaks in from the A-pillar and fried it. Worth pulling out and popping the cover off it.
