Hi everyone.firstly it's great to be here and I manage to pick up loads of useful information about my A3. I have 2010 A3 1.6 technik which I purchased from Evans Halshaw back in November. I have been pleased with it so far but about 2 months ago I have started to notice a really annoying shake when the car is idling (once choke has gone off). I took it to Audi as there is still warranty on it until September and their engineer raised the tick over. I had to take it back later the same day as it was still the same. The engineer raised the tick over more and told me that this particular engine was renowned for doing this and nothing else could be done and it was not showing any errors. I explained that the car did not do this before and that in my opinion it had developed a fault. I lifted the bonnet so that he could see the engine shake unusually now and again like it was slightly misfiring which sends the vibration through the car. He again said this was normal. As you can probably see from my post, I don't know a great deal about cars but this doesn't seem normal on a car I paid £11000 on a few months ago. It has only done 21000 miles. Please can anyone help with any suggestions. Does anyone think that Audi are just trying to get out of repairing this problem because it is going to be an expensive repair for them under warranty? Is the 1.6 engine usually a problem? Cheers Garry.
