From Bing Translator: Has anyone ever happened? Hot exhausting Audi TT 8j?
I hope an answer in English is working for you.
I would suspect this is about an exhaust that becomes so hot it is causing other problems. I don't remember reports about that.
Maybe we would have better hints if you shared more Information about the car (engine, when it was built), if it has any tunings and what they are, and also specifics about the problem.
