    VCDS is showing fault with throttle body:




    17580 / P1172 - Angle sensor 2 for throttle actuator G188 signal too low.


    or (on other scans show)


    17579 / P1171 - Angle sensor 2 for throttle actuator G188 implausible signal.




    also fault showing with ABS brakes:


    01314 - Engine Control Module - 013 - check DTC memory






    Car will drive for a bit when DTCs are cleared and throttle body adapted but then will go into limp home


    mode (can't go above 3000rpm).




    Have tried a second hand throttle body but still getting the same issue (but less often / sporadically)


    (reading MVB 062 in VCDS shows steady values / signals for [G187] and [G188].






    However the original throttle body I had on there was definitely on the fritz (or could be bad wiring,


    connectors or ECU damp?) as when reading measuring block values / MVB 062 you could see sensor


    2 G188 fluctuating wildly and not holding a steady value when at idle position




    Don't want to fork out for an OEM throttle body at £500!


    But also don't want to buy a cheap knock off.




    Any advice on this issue would be greatly appreciated.


    Thanks

    VAG Error Code: 01314

    Fault Location:
    Engine Control Module (ECM) - Check Diagnostic Trouble Code (DTC) Memory

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.

    Fault(s) stored in Engine Control Module (ECM).

    Possible Solutions:
    Check Engine Control Module (ECM) for fault codes.

    Special Notes:
    Engine Control Module (ECM) stored a Code which influences other Control Modules Functionality.
    To clear this Fault Code you will need to correct the Problem in the Engine Control Module (ECM) first.

    Thanks for your quick reply Keith,

    As per the DTCs I have checked the engine control module and get the 17580 or 17579 error code.


    I did replace the connector to the throttle body from the main engine wiring harness as the tab had broken so depinned and put another I had on so to ensure a good

    connection (it was a 6 pin connector).


    This still didn't remedy the situation....


    So went out a bought a new throttle body (Metzger)..... also replaced the lambda sensor (pre-cat) as this was original and due a change....had to fight to get it off but it come

    off with some pd blaster and heat.


    Disconnected battery for 30mins whilst carryout the work then reconnected, cleared all DTCs and readapted the throttle body.

    Been out for a drive and no error codes yet..... (though the 01314 seems to keep reappearing...not sure how to remedy this one?)


    I did take a peek under the scuttle to look at the ECU (harness is 03C 972 619 M) and can see the "faceless bolts" have been replaced with hex, is this likely to have been

    removed in past and tampered with if it has these in or are they found in other cars, I've read they should be tamper proof bolts here (not hex).


    Concerned that the ECU might be dying or have been tampered with / remapped..... but saying that car isn't that nippy so can't have been....

    Have you tried going into the ABS module and Engine module idividually and clearing the codes? Even though the engine doesn't have a code stored just clear the codes.

    Hi lemta, thanks for your reply....

    Will give this a go tomorrow.

    I've given this a try before and the code does eventually disappear after clearing a few times.....but does seem to reappear for some reason?

    Seen a few posts regarding the relays or fuses that could be the culprit?

    Thanks

    So I gave clearing faults in each module a go and still the same problem even with a new throttle body so I guess that rules that one out...

    Next I will need to take a look at the wiring harness from that connector back to the ecu plug?

    Not sure how I can back probe these connectors though unless i use an inductor clamp / pickup.


    Haven't accessed the ecu to see if it is water damage (need to get wiper arms off with removal tool).

    It's probably your wiring harness from your throttlebody to your ECU that is the culprit.

    OK thanks Lemta just taking a look at the wiring diagram now....would I need to test from ecu plug to throttle body plug? Would I be better off just replacing the lot to save trying

    to track it down?

    Should I be testing resistance and continuity between the ecu and throttle body plugs?


    ECU PLUG (80PIN) TO THROTTLE BODY PLUG (6PIN) - J220 TO J338

    T80/80, T80/66, T80/68, T80/55, T80/75, T80/61

    T6x/3, T6x/5, T6x/1, T6x/2, T6x/4, T6x/6



    Thanks

    Thanks for the advice.

    Just need some help to gain access to the ecu in the plenum chamber.

    How do you remove the bulkhead to get better access to remove the ecu?

    Are the bolts hidden behind the sound insulation?
