I've a March 2010 Audi S3 Sportback so nearly 4 years old. It's only had two services as it's on "long life servicing", last having been done just about a year ago and it's coming up for 27,000 miles, I've put 5k on it since the end of October. I'll be keeping the car for at least 5 years so when I do come to sell it it will be nearly 9 years old and probably have somewhere in the region of 100,000 miles on it. Audi are wanting silly money to change oil and an oil filter, I shudder to think what they will want when you add in plugs, haldex oils and so on. I'm seriously considering doing my own servicing on the car and to hell with the dealers, I'm a pretty capable DIY mechanic having done most jobs over the years like brakes, suspension and so on, even stripped down a Subaru 5 speed transfer box while on the car, replaced the full set of bearings and rebuilt last year on my own and it's still running well despite the new owner liking to drag it at crail raceway regularly. For bigger jobs like timing belts, pulleys and pumps I'm happy to pay a respected Audi specialist independant to do this for me as and when required. I'm not convinced at all with this long life servicing I'd be more inclined to change the engine oil and filter at least twice annually anyway. I also get trade prices from TPS on VAG parts. So lets fast forward 5 years, you are in the market for a used S3 Sportback and mine comes up in good condition and average mileage. Would you pay less for the car if the last 5 years the car had had oil, filters, plugs, brakes and other minor bits changed by the owner, of course all within keeping with the service schedule, fully documented on the service book & receipted. In fact the oil and filters would have been change far more regularly than an Audi serviced car. Personally it wouldn't bother me one bit given the car is older and higher mileage. I'd actually have respect for the guy having taken pride in his own car provided everything had been done as and when required. I suspect not everyone would view it this way though. Your thoughts....? P.S before anyone jumps on the "you shouldn't have bought an Audi if you cant afford the servicing" bandwagon, don't, I can more than afford to pay for dealer servicing but just because I can does not mean I have to. Plus I actually really enjoy working on my own cars anyway.
