    help, please decipher vagcom error codes!

    any idea what the following vagcom errors are and how to fix, i have a 1999 A3 1.8t sport and did the autoscan (im using 311.2-N):
    Address 01 -------------------------------------------------------
    Controller: 06A 906 018 AQ
    Component: 1.8L R4/5VT MOTR HS D04
    Coding: 04000
    Shop #: WSC 06325
    1 Faults Found:
    17967 - Throttle Valve Control part (J338): Fault in basic settings
    P1559 - 35-00 - -
    Readiness: N/A
    ..the other addresses have no fault reported.
    thanks!

    EDIT: removed other errors as they dont seem to be coming back but the above one still does.

    While I am no expert, the only one that I think might be a problem is the temp sensor as these are prone to failure. I would clear the codes and see if they return. The intermittent nature of most of the faults indicate that something happened once or twice and set the codes.

    You didn't say your car was misbehaving. So I am assuming all is working well except these codes are stored. Again, I'd clear them and then in a day or two - after some driving, I'd scan again to see if they returned.

    right, cleared them all and the only one that came back was:
    17967 - Throttle Valve Control part (J338): Fault in basic settings

    havent gone for a drive, yet (quickly tried clearing them before heading off to work this morning), but any ideas/suggestions? Connection to the Throttle Valve Control part (J338) has come loose or something basic like that?

    cant say i've had the car long enough to know that something is wrong, if i didnt scan it, i wouldnt have thought "ooh wait, the throttle valve control seems a bit off"

    First off, this should be helpful...

    http://wiki.ross-tech.com/index.php/17967/P1559/005465

    ...or in other words: Perform the Throttle Body Adaptation

    The airbag codes are a bit scary, but could be caused by a disconnected battery and the same applies for the central locking codes (except they are not scary).

    okay had a read through that, im assuming i have a NDBW car, i did notice this:
    There are certain test conditions that must be met before doing a TBA:

    *

    No DTC's in the Engine Controller
    now whats a DTC? and also
    Procedure for performing a Throttle Body Alignment on Cable-Throttle Cars:
    These are cars with a physical cable between the accelerator and the throttle, but WITHOUT an ISV.
    ..whats an ISV?

    sorry, but im a bit basic with cars

    Correct, your 1.8T AGU engines uses MVB (Measuring Value Block) 098 for the TBA (Throttle Body Adaptation). Make sure that no DTC (Diagnostic Trouble Code) is stored, the 17967 doesn't matter in this case. ISV means Idle Stabilization Valve.

    Have you done the TBA yet? No, I don't think yours has an ISV.

    i tried the throttle adaptation using vagcom, selected 098 as detailed here http://www.ross-tech.com/vag-com/cars/throttlebody.html --clicked on go then switched to basic settings.

    it went from idle, part throttle then errored. for my troubles i've gained another error, see below.

    Take out the throttle body, clean it and check connectors/wiring - then do the TBA again.
