Good evening everyone, so new here and already I need help/ advice from you experienced Phaetonists I found today, that if I step on the accelerator pedal in the stand and go down again, then at about 1000 revolutions a short “crack” can be heard from the engine room. One hears it only with open windows. It doesn’t matter whether the selector lever is on P, or N. I’m right next to a buddy, who drives an A6 3.0 TDI, Bj 08. With him that’s not so. Otherwise the running wash sounds quite normal, 100% just like with the A6. Does anyone know this phenomenon perhaps? I would be grateful for any hint. My fat guy is Bj 03.2009, has 109,000km down, 3.0 TDI, 239PS (CEXA) Already many thanks and nice greetings Matthias
