Hi!
Which motor do you have in your Passat? Have you tried checking for anything else to fix the problem?

Sounds like you are having fun with this one! I'm having issues with a VR6 at work right now and it's driving me nuts!

The oil you found is there on every one of these motors, so that's not going to be a problem. Sounds like you are on the right track, though. I'm not sure if it's a mis-diagnosis from the tech that replaced the motor. Without the history, I can't tell you that.

The two codes you have both point at the camshaft position sensor. The P0341 is a camshaft position sensor range/ performance problem, and the P1340 is a camshaft/ crankshaft position sensor out of sync code. This means that if the two sensors are not syncronized, the computer can't tell where the pistons are, so it cannot tell when to fire the coils. I think you are going to be chasing the camshaft position sensor on this one. This is not an easy one to chase without a lab scope, but I'm going to give you some tests.

The camshaft position sensor is number 1 in the diagram. It's on the right side of the motor. To start with, disconnect the 3 wire connector from the sensor and turn the key to the run position.

Check the voltage across pins 1 and 3 and tell me what you find.
