Audi S3

I am writing regarding the purchase of my 2007 Audi S3 and bring to your attention following issues:

• Since the first day I collected the vehicle the traction control light were on and could not be switched of. • The oil filter housing had a crack in, but they fixed it. As well as the headlights and brakelights were not sealed and water gets into the units whenever it rains or the car gets washed. • Whole quattro system (Haldex) did not work. (I was never informed of that) • All 4 of the cars rims are bent and still not fixed. • Car goes into limb mode as soon as it gets to running temperature. • The front and rear bumper were scratched by M&S Motorlink while the car were in for the Oil filter housing repairs and never resprayed as promised. • All 4 rims were also scratched by M&S Motorlink while in for repairs. Still not resprayed • Turbo on the car broke. They installed the wrong and smaller turbo on the car and that is why the car still goes into limb mode. • It was promised that a new turbo will be installed on the car. I still don’t know if it is done as the car is still in their possession. • I noticed that the front wheel arch on the right side has got a new dent. (must have happened while repairs were done) • The driver side doorpanel are broken since day one and still not fixed as promised. • The driver seat also got a tear in the leather since the day I purchased the vehicle. It was said to me that it will be fixed. • Apparently the manifault of the car seized or broke and this is the reason I am still waiting. A new manifault is being ordered for longer than a month now and still no progress. I phoned the dealership (M&S Motorlink) and spoke to the owners. They told me that the car will be fixed as soon as possible and now it is a year and two months later and I still don’t have my car back. After 1 year and 2 months I still don't have my car back. Could anybody please assist with some advice?
