I thoughtt the DSG oil change was every 40k miles - not every 4 years?
I guess its whichever comes first then?
Technically, it is only mileage based. However, oil deteriorates over time, and on low mileage cars, the oil is particularly suceptable to problems with condensation in the oil.
So every 40k miles is 'gospel', and every 4 years is just highly 'advisable'.
