From what I understand the 4th year service should be the following;
Vehicle system test,
Engine Oil and oil filter changed,
Dust and pollen filter changed,
Brake fluid service
Can anyone confirm that this is correct?
I will also ask for the longlife oil to be used.
I'm lucky with mine.My mate is a techie with VW so mine gets serviced for beer money & get the main dealer stamp.
Theres just not need for that now is there, b@stard ! 
Very unfair

I don't know of any VAG specialists in my area the only ones I know of are in Glasgow (which is about an hour drive without traffic)
