Hello, many times new threads are started and simple questions are asked about the defects of certain engine types. In order to simplify this thing, I ask everyone who has driven or still drives an A4/A6/A8 2.5 V6 TDI, for a short time and in touch his data (KM/Bj) and the defects on the engine or the attachment parts to tell. The point is that not always with various defects like inrun camshafts and timing belt cracks a new topic is started immediately and according to the frequency orak ******** IMPORTANT******** It’s not about opinions and “…I’m going to give the Bose system a chip tuning.” But if you’ve chipped your engine, you should definitely write it about it (since when). I hope for a lot of participation, because that’s the only way we get more objective results. MfG Beeralpina
