Special Notes
When this fault is found in the NAR Market 2.0L CR TDI:
Measuring Block Group 034.2 (specified) and 034.3 (actual) G581 Vane Position Sensor values can be logged to see if the fields should mirror each other or deviate to confirm a problem.
NAR market vehicles that had TPI 2025464 | TSB 21-11-01 -or- the latest TPI 2025464/5 | TSB 21-13-01 completed to prevent no-start conditions in cold weather caused by a frozen intercooler may want to see this thread.
