BMW Questions? Ask a BMW Repair Expert for Answers.
hello, what question would you like answered about this?
I think the problem is most likely a failed SMG control unit, or mechanical gearing issue
unfortunately the smg transmission cannot be diagnosed with a p code reader, so the actual BMW faults will need to be scanned and proper test plans run as suggested with a BMW factory scan tool or equivalent
if you need a non dealer for this, check out www.bimmershops.com or www.bimrs.org for options
