i got last service at 35k so i am not that far off, does 40k call for fuel filter?
Scheduled oil and filter change is every 10k miles (10k, 20k, 30k, etc). Scheduled Fuel filter change is every 20k miles (20k, 40k, 60k, etc.). If you have a DSG transmission, scheduled oil and filter change for the tranny is every 40k miles (40k, 80k, etc.).
also do any of the chain stores sell the vw approved oil or is it best to get it at the dealer? and if so what should i expect to pay?
The only "chain store" I know of that sells the correct oil is PepBoys (Mobil 1 ESP). You can also buy it from the dealer, or any number of on-line vendors. Just make sure that it says VW 507.0 approved on the bottle.
Have Fun!
