2015 bmw Z4 Unredble ECU
2015 bmw Z4 Richie attempted to read the ECU while I was down at AC. It would read the data from the breaking system but would not link to the engine at all. We tried again lately, but it refused to read anything. This irritates me since I can't read the ecu, which is concerning, and I also can't reset the service lights. Anyone have any suggestions?
