2004 Audi A4, quattro, 3. 0l v6. Premature failure of powersteering rack seals causing ps fluid to leak out, and render the car impossible to steer, until fluid is added or rack is replaced. Research indicates that all Audi power steering racks fail within 6 years. Dealer never bothered to check ps fluid levels during regular required maintenance periods. As usual Audi corp. "vehicle is out of warranty" govt agencies need to put Audi on notice for sub standard parts with premature failure, that can cause a serious accident.
The steering rack has a hole in it and is leaking into the boot. The problem just started. I noticed a sound and stiffness in the steering wheel which goes away after the car is mobile for about 3 minutes.
I began to notice a rattle in the right front when going over a bump. It seemed to come from the suspension. At the same time I noticed a slight thump in the steering when stationary and slightly turning the steering wheel to the right. As the rattle was getting worse, I took the car in to get it checked. The problem was that the steering rack had loosened at one end. It was torqued down and lock-tight put on the bolt. I am fearful of what might have happened had the rack failed entirely. I have approximately 27,000 miles on car.
