I just had my clutch, slave and dual mass flywheel replaced in my 2007 8P S3 and now I have problems that I can't explain. I was hoping you good people could shed some light on it.
1. Every now and again there is a big miss in the power and then it boots me in the arse. It feels like a big jolt almost like someone has just rear ended me slightly. (The mechanic said it was the ecu relearning after the battery being disconnected.)
2. There is a droning/vibration happening whenever I decelerate through 2500 rpm. It kind of sounds like a big bore exhaust except the noise is coming from deep in the engine bay somewhere. (The mechanic said it could be the ecu controlling the exhaust flap differently after the battery being disconnected.)
3. It is much harder to get into 1st, 2nd and 3rd gears. It used to be so silky smooth to use those gears and now I dread changing gears. (Mechanic said that I should get the gear oil changed despite the fact it's only 9000km old and genuine VAG gear oil.)
4. I went for a long drive three days ago and near the end of my drive I put my foot on the clutch pedal very slightly and there was a massive vibration/judder. It seems to be intermittent because I've been trying to replicate it without much luck. Sometimes it vibrates a little but never like that one time. (Mechanic told me that it feels fine to him.)
Does anyone have any idea if these things are related or what could be causing them?
When I dropped my car off to get the flywheel replaced originally I asked if I could look at my new dual mass because I was curious as to what one looked like. I played with it and I noticed it had a lot of slop. The top mass would slop around by about 10mm completely freely in an axial direction and about 2 to 3mm in a perpendicular direction. I told them I thought it looked suspect and they agreed. They sent it back to their supplier but the supplier returned it and said it was perfect.
Any ideas would be greatly appreciated.
p.s. I did google the vibrating clutch pedal problem but most of what I found was about diesels.
