Car throwing timing errors...
My daughter drives an 02 A4 3.0. We've had the car for about 2 months and it's been running fine till today when the check engine light came on. Car has 137k miles and I was told the timing belt had been done at 109k.
I popped in my OBD tool and read 3 errors:
P0015 (Cam Position Actuator B - Bnk 1 Timing Over-Retard),
P0021 (Cam Position Actuator A - Bnk 2 Timing Over-Advance),
P0011 (Cam Position Actuator A - Bnk 1 Timing Over-Advance).
Now, the car doesn't run rough like I'd expect it to if it had jumped a tooth. When I listen, it does sound a bit squeaky, more like a belt or a pulley than any roughness but I dunno. Is there a way to confirm the timing is off vs a sensor just being gone? I mean if the belt skipped a tooth, how bad would it idle? And don't P0015 and P0011 seem to contradict each other (ie point to a sensor error)?
