A209 2005, recently purchased, bought a MB V2.0 scanner and connected it to car but it only reads ECM and TCM modules, the other modules come up with a connection error. There was one historic code in ECM, a P202B-008 code. The only problem I have with the car is the Parktronic system is not working, shows red on the parking sensors display and I was hoping the scanner would help me solve problem but can’t connect. Any help in why it is not connecting would be appreciate.
