Funny that you mention driver style, this is my wife's car; she drives the car quite aggressively around town, much more aggressively than she should, but I've grown tired of trying to influence her driving style.
The filter used was a Mann; I believe this is the Audi OEM filter. The oil was Amsoil European 5w30 low-SAPS oil(no supermarket or cheap internet oil) so you can understand the low numbers for additives.
I have changed to the factory fill Castrol this OCI and will sample again, hopefully with better results.

I think three possible reasons, might be a cheap or bad oil filter. They paint them orange to warn German car owners! Or if not, then the supermaket oil that has low Calcium and No Magnesium adds inclusive with the oil, is not helping keep the carbon in suspention. No Moly, very low Zinc, less detergents, just like budget Internet oil. But seen similar result of insols out of limits from overheating, or very high idle time.
VW and Audi engines have a reputation for not liking low Zinc adds, forced on oil companies by crazy DPF. Second result in thread seems to show that.
Thankyou for posting both UOA rsults and I agree with what second man said, if the figures don't improve use a better oil with more Zinc. 5,000 mile OCI until mystery solved.
