G05 X5 booked in driver window switch not working. Customer had taken it to a dealership where a BDC control unit was diagnosed as the issue and replaced + - R25k, and soon after actual switch was replaced, but the issue still persisted. After 4 hours of troubleshooting and diagnosis at Gustafs Garage, we found a broken communication line on the contactless boot opening system for the LinBus. Fix one wire, boot system + window switchblock working again. Do not hesitate to call for any BMW/Mini related issues.
