i have recently purchased my 2006 2.0tfsi and I have had nothing but trouble since I bought it from a local car dealer, not naming names but it's a Renault dealer in bury.
My latest problem worries me slightly, it has just covered 66k. I was driving along the motorway for 20 minuets or so before I came off, as I got to the bottom of the slip road and went into neutral the revs half at 3000rpm. I switched the engine off and and started again, this time it sounds like it has a major misfire and idles all over the place, after 30 seconds or so the revs start to creep up to 3000rpm again then drops again and idles rough.
Your knowledge would be greatly appreciated in helping cure this fault.
p.s I have felt the car has been underpowered before this but just thought I had got used to the power.
