Re. advice on ongoing servicing:-
If you have bought it from a dealer and it’s been serviced as part of the sale, then it might be wise to treat that service as if it had never been done, since it’s highly unlikely that quality oil and filters would have been used, in preference to the cheapest available.
Our humble 1.6 A3 covers about the same mileage a year as you intend to do with yours, so I’m happy to pass on my regime, which has stood me in good stead over 180k miles:-
Renew engine oil and filter annually even though only covering 6K/a. I only use VAG’s own brand - Quantum - and buy from reputable retailers on EBay. I use Mann filters, with the oil filter changed annually, and the air, and pollen filters changed every two years. Again reputable sellers on EBay are a good source, and I generally favour Parts in Motion for good service at competitive prices. If it were mine, I would treat it to oil, oil filter and pollen filter now, and use this as the base point for ongoing servicing.
Just let us know if we can help further.
Regards, Gareth.
