My 2014 Audi 3.0 TDI with 180Kw CDUD engine indicates that the engine oil gets a high soot content. Using VCDS you may find the value "Soot Index". This "Soot Index" is calculated by the ECU and is presented in Km. Shortly spoken this value is twice as high as the actual driven distance. When I change the oil at 15K Km, the Soot Index value is 30K Km. Therefore I sent a sample to Blackstone Laboratories and asked them to analyse the soot content. The result sets aside that there is a problem with high soot levels. Only 0,2% Soot was measured. Otherwise the report indicates that the engine is still not completely broken in with elevated Iron particles. TBN was also good. I guess I could have extended the drain interval, but will stick with 15K Km at least until the engine is broken in.

Since this is just the second oil change for your Audi, we are probably still seeing some material in the oil leftover from the wear-in process. New engines always leave excess metal and silicon (from sealers) in the oil and it can take a few changes to wash out, so we doubt your levels are a problem. Universal averages show normal wear after about 10,000 km use on the oil. The oil itself was in good shape physically. Some active additive was still left with a TBN of 2.8 and soot was low at just 0.2%. Check back in another 16,000 km to see improvements.
