Not sure if this is related or not. I have a 2004 A4 3.0 with 82K miles. I bought the car new and have had the dealer do every single service on the car. No one has touched the engine except for the dealer. I have never had the oil light come on or added any oil to the car. But I now have to spend $3500 to fix the damage done by a worn/warped cam shaft lob that ultimately broke a lifter. I had no warning lights, no loss of power or bad engine performance, just a loud clicking noise after the car sat unused for 5 weeks. I asked the dealer what would cause this and he said "they don't know" but maybe oil sludge.

#16 of 18 Sludge problem and Engine Damage after Audi Dealer Changes Oil by audiowner1

Within 10 minutes of pulling out of the Audi dealer after it had changed the oil on my 2004 A4 Cabriolet, 3.0 engine, with 109,000 miles, the oil light went on. Called dealer, who thought it might not have put in enough oil. Completed drive home and then next day drove to another Audi dealer that was open, and oil light went on again about 10 minutes into drive. 2nd Audi dealer confirmed oil level was proper. Then drove home, during which oil light went on again after 5-10 minutes. Car started driving roughly. 1st Audi dealer towed in car and claimed that engine "might" have sludge problem that first appeared (mysteriously) immediately after it had completed the oil change. 3 days later, dealer claims car needs a new cylinder head. Car was fine before the oil change, and now needs $4,000 repair. Make any sense to anybody?
P.S.: The dealer had always used regular oil, but for the first time had suggested synthetic oil before this oil change. Not understanding why a 7 year old car would suddenly need more expensive oil, I had them use regular oil. Did they know something I didn't?
P.P.S.: The recent class action settlement was for the 1.8T engine. Has anybody else had similar problems with a 3.0 engine?

Just wanted to update all you folks who have or are unfortunately planning to buy the Audi (lemon) A4 2009 or newer models. My 2009 A4 sedan now has 30K miles (and under factory warranty), has been drinking oil every 2000 + miles, so needed to top off oil very frequently, brought up this issue to 2 Audi dealerships on several occasions, and finally one dealership, found faulty Piston Rings which are being scheduled for a replacement job. So much for the Audi 'Logo' / 'Status' of being a luxury / sporty / fun / reliable car. Does not even remotely fit any of the above mentioned characteristics. You would have far better luck even with a Toyota!! NO more AUDI / NO more German makes. SUBARU makes equally good AWDs + has the boxter engines, with reliability, comfort, handling, safety superior to the Audi.
