My DIS has a seperate indication for Oil Change and Service, currently it is saying I need an Oil Change but the Service isn't due for 4k Miles. I phoned Audi and they want £140 for Oil Change ( a lot for an Oil Change but bearable I guess ! ). So if I get the Oil changed then take it back in 4k is the Service cheaper as they don't need to do the oil? I'm assuming the Oil is now seperate as changing it now and in 4k seems excessive to me. In fact what do they do at the Service - just inspection and Air Filter ( not even sure they do that at 20k, the spark plugs last 60k according to the manual ).
