Hi all! I'm new to the forum I wish I could have joined and told you all how happy I am and how great my audi is but unfortunately I'm a little upset lol I bought my audi a4 s line 2.0 tdi 140 last Saturday picked her up Tuesday and was well impressed! 12 months mot 6 months tax and a 12 month RAC warranty.. Drove fine pulled great performance was brilliant up until Friday! As I was driving home from work I noticed a lack in power but believed I was used to it already. When picking the other half up from work that night I noticed power had definitely gone! Once stood still ticking over whole car shaking! The engine was making a horrible noise like it's missing!? When I try to drive it hard it try's to pick up then shakes like there's sone kind of blockage or restriction!? I'm really worried and don't no where to start! I have visually checked under the bonnet but cant see anything! Please help!!!!!
