I recently purchased a 2008 Audi A4 2. 0 with approximately 37,000 miles on it. I've driven the car less than 3000 miles and had to add 1 quart of oil every month of ownership (3). Audi dealership says this is normal. Like the previous complaint listed on this topic, I too have see a number of blogs on the subject of the 2008 A4's having issues with excessive oil consumption. I've also seen mention of a technical service bulletin being issued by Audi on this but I've yet to find it.
I purchased the A4 used with only 19k miles on it. I noticed that after driving 1,000 miles, 1 quart of oil was gone. I filled it back up and drove another 1,000 miles. The same thing. I have a family relative who owns a vw passat with the same engine and her car burned oil too. Audi says that this is a common problem and that it's something the owner will have to get used to. This is not normal, something is wrong with the engines. There are so many forums and sites dedicated to the vw/Audi 2. 0t engines consuming oil.
I have an Audi A4 2008 that has a long standing oil consumption problem. The Audi dealership in las vegas assures me it is normal for the Audi turbo engines to require additional oil 'top offs' between the regular oil change intervals. I have owned several other (non Audi) turbo engine automobiles, and I know this is not 'normal'. I have read many online forums on this topic, where the Audi A4 owner was eventually informed the engine seals were bad, causing the oil consumption problem, but Audi would not cover any costs to repair such on the 2008 A4 model. This vehicle has always used synthetic oil, which should only need oil replacing twice a year. But every 4 weeks the 'low oil' dashboard light illuminates, and I need to add another quart or two quarts. There is an Audi design flaw on the A4 engine, otherwise it would not be burning through excessive oil the way it does.
Since we leased our 08 Audi A4 quattro 2. 0t we have had issues with the car seeming to loose power and jerk usually when driving between 60 and 70mph. We have complained to the dealer and they have replaced or repaired the following under warranty: two diverter valves (first at 500 miles and the second at 1200 miles) the car would shake violently when cold as if running on 2cyl, removed an air filter pre-screen (at 5000 miles scheduled service), replaced the turbo charger and battery power cable (8500 miles). Un-fortunately the vehicle continues with the problem at 13,880 miles. Additionally, the vehicle consumes oil and now only gives us 15-17mpg in the city, which we have been told are both normal by maplewood Audi. I can say that if we had know about the vehicles oil consumption, poor fuel mileage (especially for a 4cyl engine) and the engine jerk we would have never leased this vehicle.
Purchased 2008 Audi A4 new from dealership in October 2007. Two months after purchase, notice oil consumption problem at 1qt every 1,000 miles. Dealership says this is normal but my mechanic said it is not. With the help of a pro-bono attorney, contacted Audi and demanded repair at 12,000 miles. Audi replaced rings and car was fine for 24,000 miles. At 36,000 miles, low oil light came on - 1 qt low again. Had oil changed by my mechanic and two days later a new problem - low oil pressure light comes on. Had car towed to dealership and they found nothing wrong with car (no codes, drives fine). I demand through Audi an oil pressure test. Test came back normal. They told me to drive the car and that there is nothing wrong with it. The low oil pressure light is still coming on every 20 minutes of driving. The car goes back in the shop again this week. Car is obviously defective and I am concerned about major engine damage.
