I bought a used c4 picasso bj 2007 with 122000km running power. With one year warranty on engine and transmission. Before the sale was made new TÜV and allegedly according to purchase contract one around inspection. On the first day I drove 460km and had suddenly without warning in the middle of the highway several error messages. 1. Exhaust gas detox system defective 2. System ESP/ASR defective 3.Exhaust gas system defective 4. Engine control light yellow bright And the worst as I find e the engine doesn’t run round, but stops and sounds like it’s giving up the spirit itself. Would a video upload but don’t know how this works here. It would be nice if someone could give me a tip what it might be. I know I have a warranty on engine and gear, I’m surprised it can just kick something like that after just under 500 miles driven? Or was it botched at the tuv or the inspection?
