In short,
yes.
There should be figures for
Inspection Service and
Oil Change, and the number of days for each.
The 20K miles figure is for the Inspection service, whilst the oil change using long life oils is often "quoted" as 20k miles it's start point is 18,700 miles (30,000km).
Not getting near the 20k miles in 2 years is no
problem, you are simply avoiding paying for a service after 1 year in which they do nothing but an oil/filter change.
Personally, I don't like the idea of long service intervals from a mechanical point of view, they are something which fleet managers like. However, paying a dealer £179 to change the oil is daft IMO when you can do it yourself for £35-40.
If you don't like the idea of any DIY maintenance then a local independent will charge £40-60 depending on the oil used etc. Either way you've saved over £100.
The manual has instructions for resetting the service interval reminder, or use some of the money saved to buy a simple diagnostic scanner (£20-50). They are useful to have and many have the reset service reminder function too.
In over 20 years of owing VW/Audi I've yet to see the service reminder do anything other than countdown.
The "oil quality monitoring" is much less sophisticated than the dealers would like you to believe. The sensor is simply for oil temp, that data is used in conjunction with the number of cold starts and a simple algorithm takes a guess at the oil's condition. Fairly meaningless as modern fully synthetic oils are good for a lot more than 20,000 miles unless they are taken over 135C, which should never happen during road use.
In the haulage business oil often does 50-100k between changes. It's sampled and properly analysed after 50k to determine when it actually requires changing.
Contamination of the oil is the issue, hence why I prefer more regular oil/filter changes, and there's no onboard system to accurately assess oil contamination.
