You're doing things right, but it looks like the car does not support some PIDs?
On startup, the OBDuino will poll the ECU and check which OBDII PID's are supported by the ECU. It logs these PID's that it can display, and when selecting PID's to display, it skips those that the car says it does not support...
Look in the code, and you will see a huge list of valid PID's that are currently available. The list ends with some 'fake' PIDs that we always have available.
Why is your car saying the others are not supported? Perhaps they are available from a custom tool that VW makes? Not sure. Is there a VW dealer you can check with?
