    1999 Audi A6 2.8L - 17746 16684-7 doesn't make sense

    I was driving at a highway speed pulled into a gas station, and my car all of a sudden started running poorly and the check engine light came on, then blinked! Had never seen it blink!

    I looked up all the codes - 17746 says its the G40 sensor, and the Bentley's manual shows that on the driver's side back of the engine head.

    But but but - those cylinders are marked 4,5, and 6. The other error codes are shown as cylinder 1,2 and 3.

    The car runs but really strugges at idle. The left side of the engine (passenger side) seems to be making more mechanical noise than the right (drivers) side.

    I'm going to get new cam sensors (if one died after 20 years the other is probably not going to last much longer either). But - why doesn't the info from vag-com correlate???

    EDIT: Drove the car around while monitoring Engine Group 15 - Cylinder 1-3 misfires. When I go from idle to 15 MPH the numbers of all 3 shoot into the hundreds.

    It might be helpful if you could post the Auto-Scan.

    G40 is normally the cam position sensor for bank 1, which I would think is the bank that has cylinders 1, 2, and 3.

    On two-bank engines like your V6, there may be a second cam position sensor for bank 2 as well. If so, it would usually be designated as G163.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Diagnostic stack maybe incorrectly assigned but I think is correct & stack is within controller & as a possible error from the OEM, this would not be VCDS because VCDS only reports what ECU displays.


    Probably time to take VC off and investigate the shoes on the cam tensioner adjusters, dont run engine further until inspected if you hear a noise & for fear of damaging a valve.

    Jacke does it again! I replaced the can sensor, same codes when running. Then pulled the cover and lo and behold:

    You could have gotten a few more miles out of that!

    Haha! Good save Jack! That was going to become a MUCH bigger problem, very soon!

    I first tried here but the diagnostic spirits were unrepresentative.....dam new diagnostic board scanner enhanced doesn't work.




    Than I just thought, well this has happened before, so what is the likelihood of it being shear repetition statistically?



    Good thing the MIL came on huh?
