Check CAN-Databus Wiring/Connectors from/to Engine Control Module
Check Measuring Value Blocks (MVB)
- Usually Measuring Value Blocks (MVB) 125+ show the current Communication Status

When found in a 2005 through 2007 2.5L NAR (North American Region) (1K) Jetta check the T121/62 (Red/Black) traced power wire to the ECM. If power is missing or a voltage drop is present that wire may be damaged anywhere between 6" and 18" from the connector itself. This will result in no communication in addition to a no-start.
- Based on 2.5L Jetta feedback over the years a majority look like this example however some are damaged further away per this example: Far and Close .

Engine Control Module stored a Code which influences other Control Modules Functionality.
To clear this Fault Code you will need to correct the Problem in the Engine Control Module first.
