Hi all,

I have a 2003 b5.5 Passat with 140,000k's on it. Engine is a BBG V6 2.8L 30v. Its misfiring and has erratic power when accelerating as a result.

Had a mechanic run the fault codes and we got:

1) 17755 P1347 Camshaft Position Sensor 2-G163 Engine Speed Sensor - G28: Incorrect Allocation.
2) 17748 P1340 Camshaft Position Sensor - G40 engine speed sensor - G28: Incorrect Allocation.

No recent changes to the car. It seems highly unlikely that both sensors have failed at the same time.. I have done research on these codes and found results from other engines like the 1.8T or VR6 where it was timing related.

I was wondering if anyone has come across this situation for our engines? Before i start ordering parts.
