    my s3's been missing badly coming and going (more detailed describtion in my other post S3 misfirng) and what ive replaced already..

    well today ive pulled the wiring harness out to inspect it, as ive changed near on every sensor and still nothings coming up on vagcom, anyway i pulled back the plactic sheilding and removed the black tape to reveal this..!!! is this whats causing my problems? because its arking out etc?? can it be repaired or am i looking at a new harness?

    Very typical, you should be ok stripping it all back and reseal with fresh tape, it has been the cause of some misfiring issues in the past.

    mate its completely shot..!!! i peeled it back some more and the thick brown wire is all brittle and the casing is begining to fall off... from the coil end to pretty much right to the bottom, about 2-3 foot!! and theres a red wire and a blue thats split in places aswell!!

    fairly sure a new coil pack loom is only about £25-30 from the dealers mate, and they're available for this very reason I think!

    Get a new loom section, easiest way

    going to call audi newbury tomorrow and see if its something they can get me, other than that its a case of having to get one out of a breaking s3...... id much rather put a new set of wires in tho tbh as the ones out of a breaking car could be just as knackered as mine when i strip them back!!

    How the hell did that happen to the wiring!? Looks like someone's had a butchers at it before! Solder up what you can and insulate them again and you should be fine.

    you can use the "180" version, you just might have some soldering to do.

    im also going to be a complete cretin, but isnt the dv the wrong way around? and no vac line going to it?

    that loom is shocking, iv notice mine is breaking up on the coil pack wiring but not experiancing any problems so going to leave it until it does play up.

    Works on mine

    I didn't use the full loom just cut and spliced into the old one so far back

    Done 150 miles on that loom with the 2.0 coil packs and everything is well

    The guy in the workshop is talking s**t

    They are compatible you've just gotta match each core to the correct one and splice it in (the colours aren't the same) and you do have to butcher the new one for just the bits you need

    I done this a few months back on my 225 bam and I was told that it wasn't compatable by awesome and audi told me I needed a whole new loom for £400 plus :-O

    Hmmm... Well when audi replaced my coil packs the left hand loom came back like that, I taped it up but im still having issues with my boost (which wasn't that bad untill audi had their hands on it!) its booked in now for them to have a look at the problem (gratis + courtesy car) should mention the wiring loom coming back in that state?

    Sounds like a plan xD its just gonna ruin my car for me isn't it! Hopefully mine will be a tad more fun after the map/boost issues are fixed! Would love to know if changing that loom has any effect, ill see if I can get some pics of mine up to compare it with yours, although last time I checked, yours still looks so much worse! Good luck with the fix though! I'll see if audi will fix mine for free since it happened after they played with my coil packs..

    A lighter works perfect.

    I'm having problems with my car too, always had a feeling I might be loom, might take my full loom off one day and inspect
