Can only read ECM and TCM codes
CLK200K, 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 appreciated.
Parktronic system now working.

I have today scanned the car with another scanner and same issue, can only read engine and transmission modules and came up with this error, P202B-008, CAN data from control module EIS, CAN signal interruption Drive authorization.
so the issue is with the car and not the scanner. Everything is working ok so I believe that the CAN is communicating ok, had a problem with the Parking sensors not working and found loom unplugged in boot, reconnected it and they are all working fine. I have also had an error code P2029-02 which I understand could be associated with a faulty air temperature sensor.
