    Hi guys, I had a previous thread saying i was buying another S3, well i did in the end. The Car is lovely.

    However !"!"!"

    When i started it this morning the whole front end and cab was shaking quite violently. This scared the shizzle out of me so i killed it and dapped off to check my fave forum.

    Reading previous posts it would suggest that this is a coil pack problem.

    Symtoms.

    *Cold start the car shakes and sounds like a bag of balls (possible missfire?)

    * "Clutch in" same problem in N 123456+R.

    *I let is warm up, and the shaking stops, the Idol is still quite rough and the engine seems to be hunting slightly.

    *Once warm and no more shaking i took it for a test, All seemed normal, untill i gave it some beans, it was juddery and spat a few times when picking up.

    Do you far more wise and nobel men have the same diagnosis ?

    Many "Tanks"

    Try unplugging the MAF sensor. If it then runs ok, you have a dying MAF.
    Could also be a coilpack problem as they are prone to failure.

    Like said, if not the maf itll more than likely me a coil pack so your looking at about £120 bill because you may aswell buy 4 new ones.

    Ok, started it with MAF unplugged. No change.

    Then i unplugged what i believe are the coilpacks?.... one by one and then started it. No change. other than rougher when unplugged.

    Clarify:

    MAF ?

    Run the engine and uplug the coil packs one at a time and see fi you get any difference, if none then that pack is gone.
    Sounds like it could also be an injector.

    I unplugged one at a time when engine was off then started, Each time it was worse with one unplugged. Its strange as once the engine is warm it stops shaking, however still has a rough idle.

    Before you start on the road of expenditure to try and cure it by buying one part after another, get it checked on VAGCOM. Look in the VAGCOM forum for someone in your area that has it, most people are willing to help.
    I have used my cable more on other people's vehicles that I have on my own.

    It's worth checking the spark plugs too.
    Poor idle is often caused by coolant temp sensor fault especially if you have the old black CTS. The later green CTS rarely fails.
    Dirty throttle body is also known to cause erratic idle & jerky hesitant throttle response.
    Vagcom should reveal the problem. You've already pulled the MAF & coilpacks so Vagcom will show intermittent or implausable signal faults for both of those, note & clear any codes, then recheck with Vagcom again.

    My mechanic ( who i thought wouldnt have a form of vagcom) actually ended up having one and found i had a misfire, cause was no 2 coilpack. So could just ask a normal garage, helps if your a bit friendly with them, he tested it for free and charged £150 for 4 coil packs and some other pipe that was broke.

    Spark plugs mate, I had similar issue & it was a cracked ceramic on 1 plug, easy cheapish test tbh, I'd start there.

    Coolio, i am In the Army so should be able to get a REME mechanic to have a quick look and prod with a fluke etc.

    Any recommendations on Plugs ? I've always though if something brakes its an excuse to get a replacement a lil bit better than the OEM part :)

    Always nice to give a new car a set of new plugs just for peace of mind.

    Also go for genuine coil packs if needed

    Are you sure it's not something simple like a split pipe leaking vac/boost? I had the same problem with mine poor idle/start, better when warm but still hunting and unstable due to unmetered air...

    Also, the unstable idle was causing something to clatter around when I had this problem, believe it was the clutch thrust bearing. That's now gone away as well.

    It was the crankcase breather hose to the inlet manifold on mine, quite common for going I believe - had a leak in the same place on my old A3 as well...

    I will double check hoses tomorrow, any perticular way to check ? Or is it a case of look listen and feel ?. I know the crank case breather pipe has a big kink in it. But does not explain the missfiring... Hunting maybe :)

    Thanks for the advice, Will let you know how i get on.

    Im gonna stick it in the Audi on wednesday, cant get hold of anyone with VAGCOM :(

    got a bit of cash left over, i believe its 50 quid just to hook the f****r up though !! :(

    Prolly gonna stick 4 new plugs and coils in it though..

    Second plan.. Ring the RAC ont he side of the road "broken down!" and see if they have any coils... or a cheap diagnostis of it from a trained eye ?? Whatcha reckon?

    Hi mate without a doubt i would ring the RAC if you are covered, they will be able to come and test it, and have the software to plug into your ecu and scan it,

    I used them before, when an engine management light was on my car, i phoned them up as i was unsure, if i was covered as the car was fine to drive just with a light on, they came out tested, it found out my o2 sensor was the cause,, they are really good, worth a try, for definate,

    I guess this was a private purchase and not from a garage ?

    You can get a decent Vagcom interface cable from here
    http://www.vagproducts.co.uk/products.html It comes with version 409, which will do most things. It's really handy to have & not that expensive. You can still register it with Ross tech as a 3rd party interface.

    KK, will mysteriously brake down on wednesday afternoon instead of Seeing Mr Audi, At least till its diagnosed.

    yeah it was a private buy :( Should of had an RAC/AA inspection on it.. All a bit rushed and i think i bought with my heart not my head.

    Ah f**k it its only money ! Not one to regret :) Still got a roof over my head and three meals a day :) (gotta love the army for some stuff)

    hi guys, well good news !

    Stuck it in a local garage and they hooked it up to Mr VAGCOM and Coil 1 was being a cnut.

    Suffice to say, 35 quid for coil and i had 4 new NGK plugs stuck in it..


    Total= £110.0p

    Thanks for all your help and advice. ( will be replacing the other 3 coils after xmas)
