Just joined and looking for some help if possible...
Currently have an S4 but looking for a B8 RS4. Seen one from Audi with 41K miles but looks like from the service history the 20,000 mile final front drive gearbox oil was not done. They are doing a major service now (final drive oil, gearbox oil, brake fluid service, dust/pollen filter, spark plugs, pan roof, engine oil) but will the fact that this was missed potentially be a big issue down the line?

many thanks in advance,
Chris
