Rattles V8 4.2

Hello together I have found a “rattle” at my Spyder. The rattle occurs, e.g. in the second gear, slightly undertoured, accelerated. This noise comes from behind. My garage suspected a loose part, e.g. the heat shield. Today the whole rear was dismantled, unfortunately without success. Currently the request is running at Audi in Switzerland and in Germany. The mechanics suspect a problem in the gearbox. Until this evening it was not yet clear how it continues and whether i We decided to leave the Spyder on the spot and wait for the report. The car has now just 1’000km on the clock. I now got a new S8 as a replacement (520 hp) also not bad. 😉 Gruss Traugottle
