After checking my oil and seeing that it was above ther prescribed level I took it in and spoke with my service tech. He said that it was true that Audi originally told the techs to put in an amount that exceeds the capacity. In fact, the parts department still supplies excess oil when a change is called for by service. He said that the oil should be checked cold because it is an expansive oil (when hot) and that it will always indicate past the max mark on the dipstick if it is hot. I think the protocol is for the techs to drive the car after service, which might account for some of the "high" readings people are getting when they pick them up.
