Okay, based on your numbers you have some kind of engine problem and it's time to put on the boxing gloves, before the warranty expires. You should contact the Audi Zone Office and have a factory representative come out and perform a cylinder leakdown test----these amateur chemistry experiments are not going to cut it.
It's possible you have a clogged PCV system which is building excessive combustion pressures in the crankcase---this can also cause oil burning, as can the more dreaded premature engine wear.
I think you really need to get proactive here----one might be able to argue that an engine can run a long long time while burning oil, which is true, but that doesn't make a quart every 1,000 miles "normal limits" on a 4 year old car.

Hi ts02 ...
I actually started this thread - almost 4 years ago to the day!! I sold my 2005 S4 cab in April last year. We moved out of the country and i could not take it with me ... hurt to give it up!!!
The problems you describe are very similar to mine ... but worse consumption than i ever had. I would go about 1,500 miles for every quart. But also never any visual marks on the garage floor, no oily substance in the exhaust pipes, etc. I really felt like i got the run-around from the Audi dealer. Answer was always the same ... it is within spec for the engine. They spent the entire summer doing those weight tests .... but always gave the same answer. It got to a point where i was so frustrated i would go up to anyone with an S4 or A8 (same engine) and ask them if they had trouble with their cars and oil consumption. Answer was always no ... so i think it was simply the dealer not wanting to absorb the cost of major repairs. Having said all that ... they were never willing to give me in writing a letter that said 1,500 miles per quart of oil was spec for Audi.
I would push them on giving this to you in writing. Perhaps contact Audi of America and make a stink.
Good luck ...

Thanks for the feedback. Still battling it out with the dealer. Next call will be to Audi of America.

I bought my car at 13224 ml in US. Dealer changed oil at about 15000ml in June,2010, regular oil change. In November, oil warning came on, called the dealer and they said it is normal and just add 1 quart of oil. I did and another warning came on in January, I put 1quart again. Third warning in March 28, 24374ml. At that time, I called the dealer and notified (Thanks to you guys, I now know that this car has a problem) Dealer was very kind to me and admitted that this car has the oil problem and performed oil weight test and told to bring the car back 650ml from that time. At that time they also changed faulty valve too. Oil weight test came back and now my car has a engine pistol box problem. They ordered the part and I need to bring back in 2 days. I bought 5yrs warranty, but if this problem going to have me going round, I'm thinking getting a legal advice. I really hope this solves the problem though, I love this car so much. I had same car 4yrs ago leased and never had any problem. I'll keep you guys posted as I know more!
