H5drj,
I just saw you comments on the vwaudiforum form a thread a few years old "fixed verus variable service". I am going to stick with the variable service and let the engine computer tell me when to service the car. Thought I would post here as I essentially agree with your comments, if Audi define a variable service as acceptable, then servicing at a higher frequency is not necessary.
As an aside my current A4 1.8T 190 has been on a variable service all its life. I say all its life, it was while it had it's previous company owner who racked up 82k miles in the first 3 years at which point I acquired it. I then gave it one full service at about 90k ish (oil, filters, sparks) and have then just changed the oil and filter on the variable schedule, but even this has been poorly done by exceeding the time limits by quite an excessive amount.
The car has now done 180k miles (and is now 14 years old) and the engine runs just as smoothly with no discernible loss in power. The sparks plugs have not been changed since the 9ok service and I have only just changed the air filter at 18ok miles.
I don't suggest others follow my regime, but my experience over this car and my previous one is that servicing at the intervals recommended is not necessary. I keep my cars until they fail, in the case of my current Audi is hasn't failed and it doesn't appear it is going to any time soon, so I am not concerned about how a limited service history will affect it's resale value. Of course the car is worthless at it's age and mileage but for all those that suggest a variable service has screwed their engines, my car value has plummeted to zero due to it's age and mileage way before the engine is suggesting it wants to give up.
