    Guys!!

    Changed my plugs last night the NGK Iridiums and the S3 was with Audi this morning for a service.

    Was driving home tonight and floored it in 2nd, high up the rev range the car started popping. At first I thought it was the traction control but looked down and saw the engine light flash on and off.

    It went away so, being curious, I floored it again and the same thing happend (bar the engine light)

    I then thought it might be a blow out from the Miltek or worst case scenario.....quattro fault!!

    Phoned a mate and he is pretty certain its a coil pack failure - never had a problem like this before as all my previous cars have been deisel.

    Has this happened to many S3 owners?

    How much are they from audi?

    Would RAC have these available? I am tempted to ring them tomorrow morning to come out. The car drives perfectly fine low down the revs and I have turned off the Revo.

    Any help appreciated

    Thanks

    How many miles on your car? What did a scan say? The only things I have heard of are coil pack, HPFP & downpipe issues on remapped cars.

    If it was the emissions light (the engine one) then it could be the Cyl 3 sporadic misfire issue, but you will need a scan to double check. That normally happens in 3rd or 4th though, but could be. If that is the case then the coilpacks are not the issue and you will need to contact Revo. This is more likely on a 07/08 car.

    Something similar happened on my A3 2.0T. Floored it in 2nd coming off a round about and all of a sudden, Blackpool illuminations on the dash. Nursed it close to home as it was misfiring/failing big time. Audi assist called, RAC came out. Took the boy 45 mins, I kid you not, trying to get engine cover off before he had to give up and call a colleague and then realise he couldn't fix it. Car got lifted back to Audi. Car was only 1.5 year old, so under warranty. I may be wrong, didn't ask too many questions, but was told it was coil pack/injector pack.

    I had the same thing when i changed my plugs, it whiped out two coilpack when i got 15 miles down the road - had exactly the sam issues as you.

    Coilpacks are about £27+VAT, i wuld just buy one and try it in sequence on each cylinder to see which is faulty, saves you buying all four when only one might be at fault - or scan it worth Vagcom

    Cheers

    The thing here is Revo. I had the same issue and had all the coilpacks and plugs swapped under warranty and it happened straight after. I am not saying I am definately right, but if the scan comes up 'sporadic multiple misfires detected Cyl 3 at XXXX rpm' then he will know for sure; in that case the coilpacks are a symptom and not the cause.

    Got it sorted this morning guys - was a coilpack in cylinder 1

    RAC came out at 7.20am and sorted it there and then!! Great work from the guys!

    Will give it a thorough drive today to see if it happens again

    Good news there mate, as the misfire is a bit of PITA. Do the RAC charge you for parts on a home job?

    Might be a good idea Paddy especially for £27!!!

    I have read alot of people with R32's with them giving up, so they could need the same on Audi as I presume there the same parts!

    Are you out of warrenty Bodyie? One of mine failed a month ago, called audi assist and a RAC - (Vag trained) was there within and hour and replaced the coilpack with a genuine Audi replacement FOC

    I recently had to change a coil pack on my 3.2 Paddy and when revving to a certain limit the engine management light would flash - after a few miles driving (as I was nursing it home) it remained lit permanently.

    However, I've had similar erratic idle issues to you and on speaking to the AUDI/VW specialist to which I took the car, he mentioned that the coil pack couldve been on its way out for some time and could have contributed to the erratic idle.

    It hasnt happened since the coil pack was changed BUT then again it was intermittent anyway and occured on average once per month/every other month...

    Do the spark plugs you selected have a larger gap than the OEM sparks?

    The ones I chose are exactly the same except they are NGK and not Bosch

    Update! Coilpack on Cylinder 2 failed last night on the way home from work!

    Audi is on the way home so called into them - they wanted a hell of a lot of money to help me out so I bought 2 of their coilpacks and another from a VW tradestore and headed home.

    Diagnosed the fault and said cylinder 2 was misfiring but changed all the coilpacks to the new ones - means I still have 2 working ones as emergency spares!

    Just for your information, the new coilpacks are a revised edition ending in F compared to the C versions which will probably be in the earlier S3's. Might be in your interest for those with the 2007 or younger S3's to check out.

    Anyway, problems solved for now, £120 I didn't expect to spend this month but better than the £300+ audi would have charged!
