    I assume you mean ignition timing? If my memory hasn't completely packed in I think block 020 in VCDS will give you the data you need. There might be a guide on www.Ross-tech.com but I can't remember. Have a little look.

    If you had a timing issue you'd get a more specific timing error. All 3 of your errors sound like wiring issues

    As mentioned in the other thread mate... still say its wiring issues... not really sure where to start though but have heard of this sorta thing before being due to unrelated wiring issues such as the MAF...

    No real easy way to start going about it tbh... not a problem I have seen before so not sure where I would start myself... trace the wires back to as far as they go would be the first thing to do... it might be something else shorting to earth and you are seeing a knock on from this... chances are the fault isn't even the sensors its showing...

    VCDS won't help with timing in this case as the timing is handled in the map and is what it is... the map will have varios maps to use depending on the state of things... its not like old skool distributors and the like...

    This might help
    VWVortex.com - What is Wrong: 17938 - Camshaft Timing Adjustment: Short to Ground

    Also... unplug the VVT unit, clear the codes and see what happens... do the same for each one in turn (leaving the others plug in etc) to try and isolate if its one sensor bringing the rest down...

    just unpluged them 1 by 1 and got these codes
    with n249 unpluged i got
    17956-n75-open circuit
    17938-camshaft timing adjuster-short to ground
    17695-n249-open circuit

    with n75 unpluged i got
    17956-n75-open circuit
    17939-camshaft timing adjuster -open circuit
    17695-n249-open circuit

    with the vvt unpluged i got
    17956-n75-open circuit
    17939-camshaft timing adjuster-open circuit
    17697-n249-short to ground

    and after with them all pluged in
    17956-n75-open circuit
    17938-camshaft timing adjuster -short to ground
    17697-n249 - short to ground

    Well.. that suggests wiring to me... as the faults changed... common faults appear to be the N75/N249 and unplugging the N75 swaps the VVT from short to ground to open circuit... I'd start with tracing the N75 wiring as thats open circuit all the time... I suspect they share an earth as thats typically how vag wiring is... you may have to unpick the loom by removing the tape... you can loom it back up after...

    Open circuit means the ECU can't see its connected... as they are then it suggests a wire is broken... as more than one item is open circuit and they tend to share an earth I would suspect somewhere in the loom where the earths are joined (typically twisted together) you may find the problem...

    Glad you got it sorted. Poor earthing on these cars is getting quite common due to their age.

    Whats the exact code and description from VCDS? (you can go to the ross tech wiki too for more info)

    Seeing as you have been experiencing wiring issues it could be related to that again but yeah, EGT sensor is not a cheap item sadly...

    Sounds like wiring issues again mate... the reason you are using fuel is because the ECU relies on the EGT probe for feedback as part of its engine protection strategies... if the ECU can't see it (as would be the case with the fault you are seeing) then it will overfuel for protection...

    I would advise getting it sorted sooner rather than later... you will end up with bore wash and will lead to damaged rings and worse..

    Considering the other issues you have had I would still be looking at wiring issues mate..

    Not on the EGT sensor no...

    The probe fits into the turbo hotside and the sensor electronics are underneath the inlet manifold... remove the trim panel in front of the inlet manifold and the EGT sensor plug will be there....

    You will need to check the wiring back to the ECU...

    AMK ecu doc can be found here...
    https://docs.google.com/file/d/0B_V9...3NzEwMjgx/edit

    EGT Sensor wiring (G235) goes to the 121 pin plug pin 61...

    Check the other wiring too but unplug the sensor first

    Just a update
    Thanks to the wiring diagram tuffty checked them from the sensor down the loom and to the ecu all were ok so I thought I'd take the sensor off and check the probe when I got round the back of the engine I managed to unscrew this with my fingers any ways the probe was covered in soot and ****e cleaned it up with a bit of wet and dry and bobbed it back in went for a good 20 mile drive just incase and the code hasn't come back so touch wood this has fixed it o and don't think iv ever been so happy to see my mpg back in the 20s lol :D
