general problems of the 2004 Audi A4

On numerous occasions the automatic brake system engages the brakes with no warning. This dangerous and possibly deadly situation has been reported to the manufacturer and many authorized dealers.

I was driving my Audi A4 2004 down a slight slope and had to stop at the red light just before crossing a major highway (va 123). As I saw the red light, I tried to press on the breaks and around the same time, I realized that the car started shaking as if it was about to stall. However, the car did not stall and the break was rock hard. I couldn't apply the breaks. I lowered the gear and used the hand break to stop the car. I had the car towed to the Audi dealer. Dealer told me that the suction pump valve split into two and that is why the engine suddenly got too much air and the break power assist also failed. They have replaced the suction pump. The old part has been trashed.

Been a not so proud owner of a Audi A4 2004 , and having a number of documents issues with my call and receiving poor service from my local dealer. At approximately 3000 miles before my warranty expired the front brakes starts to make grinding nose after taking to the dealer the dealer informed me that the brakes needed to be replaced including the routers (which by the way they never replaced under the maintenance despite the fact I requested them to check my brakes every time I took the car for service and they kept telling my the brakes were good). At this time they informed me that I had to pay $320. 00 to have my brakes replaced. What I don't understand is my did the dealer waited for the router to the full damaged before replacing them.
