- Based on my research, there is no public documentation for the BBW engine from VW that details the actual vs. specified limits.
- I would take the fault code for what it is worth, incorrect correlation. Simply put, at some point in time, the saw the value beyond the limits that the VW engineers implemented and set the code. So the timing relationship between the G28-Crank Sensor and the G40-Cam sensor, the timing is off, personally I would imagine 1-2% may not be that bad? I could be wrong
- My suggestion is to clear codes, start Data Logging
-091 and -003 (for ref) and drive the vehicle until the code sets.
- Post the Auto-Scan
and the small part of the data log where the discrepancy occurs.
