I'm trying to do a complete preventative maintenance service on my '01.5 S4 since I just bought it (I always do this to any used car I buy). Oil change, fuel filter, coolant flush, gear oil, spark plugs, in-cabin filter, etc., etc., etc. I'm having a hard time collecting all of the basic maintenance specs. I'm finding some here and some there but a complete comprehensive list would be great. Is there a website which contains this info.?

Recommended fluids, fluid capacities, torque specs, spark plug brand/part #, spark plug gap, OEM replacement part numbers, etc.

Thanks!
