    No engine light on...nothing on dash to suggest there is a problem. car only has 74K on clock and has been looked after well before I bought it last August (2008). It is due for its annual service, but other than that, nothing has come up to suggest there is a problem...Have got a mate of the ex's who has his own VAG garage, but hoped I could fix it without paying out too much. thanks for your response.

    I did wonder if it was a turbo problem, but I'm a girl and know little about engines, other than what the ex taught me! the juddering is only slight. I had same problem but worse on my old VR6 and that turned out to be a really ioled up spark plug. once that was changed it was fine...plugs on my A3 have been changed, but problem still evident.

I have the same car its a 1.8T A3 1999 and had exactly the same issue. Took it to a garage and they replaced the coils.. still had the same problem.. then I had a different issue with the car and realised it had the original battery and this was almost dead. I replaced the battery and now the car is running perfectly again - Im not saying that it definately was due to a dud battery but I reckon it was and suggest you get yours checked out before spending £300 on coils that dont need replacing.

One of the four Ignition coils might be bad, do you have a check engine light on?

    A bad turbo wouldn't cause a miss, it would cause a lack of power or oil consumption.

I have yellow check engine light on in my 2008 kia rio and just took it to autozone and they ran a scan on it said misfire cylinder 1whats that mean and how can i fix it ?

I had the same problem with the engine misfire on my 2006 Kia Rio, I took it to 5 garages, I took it to Kia, they were all ****, and had no answer to the misfiring of my engine, yes the "engine light" came on all the time, and sometimes the engine light stayed on.

They all tried flushing the fuel injectors, well that didn't work, and they were confused why it didn't work and said that they couldn't fix it, some said it was a piston, and you might have to overhaul the engine, after that and lots of money spent I had the same problem and thought to myself,well that was one ******** theory, they were so bemused by the whole misfiring of this engine and said they couldn't fix it.

They ran lots of computer tests on my car with a misfiring code that showed up, but a code is just a code with no step by step instructions to fix the problem, no one couldn't fix the misfiring problem.

$1500 later I was about to give up until my sister said that she had found a descent mechanic, told him about my problem and told me to bring my car in.

Well to my amazement, he found the problem, the misfire was caused by the coil that had been shortening (an electrical shortening), and there was evidence of a burn mark on the coil, well he changed the whole coil and changed the spark plug leads and now the car doesn't misfire and works great - I hope this is a solution to your misfiring problem, I thought I would share my story about my Kia Rio misfiring problem - Have a great day everyone.

I got audi a6 2.8 lit. The engine misfires especially on low revs on 1st and 2nd gear. When revs increase misfire decreases. I have changed spark plugs and leads. Tested in audi preston diagnostics - no...

I have a 1999 A6 2.8, and my car was doing the same thing. However, after spending about a $1,000.00 I took it to another dealership. they replaced the fuel filter, it was dirty from putting cheap 91 gas in the car. Once it was replaced the car ran like new. I had to replace it around 80,000 miles. Hope this helps

Audi A6 Misfires

You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.
