Hi guys new here and hoping for some advice please. Looking into buying a 2015 A6 Allroad , 272bhp , 3.0 tdi believed to be a CRTD engine ? 3rd gen ? I have been warned off this particular engine at this sort of mileage as apparently they are problematic? Reasonable service history , 89k , looks straight enough but I don’t know enough about them. Can anyone share their experience of owning one , what to look for or what to avoid ? Thanks
