2002 Audi allroad 2. 7t. This vehicle is equipped with air suspension. The pump assembly is located under the car in between the rear wheels and has a protection cover. This car is allwheel drive and includes standard amenities such as a skibag. One would expect this car to hold well in cold climate. After 8 yrs of use, the pump assembly is corroded to the point where it has separated from its support. It is still operating, but now appears to rest on the protective cover, which itself is held by three fasteners also corroded and disintegrating. A concern is that the assembly falls off and presents a hazard for following vehicles, as well as a hazard for how the car handles as this pump feeds the air suspension. Pictures of the corroded assembly and cover fasteners are available. A search on Audi-forum shows that there might be other instances of the same for this type of vehicle at about the same age.
I had stopped at a light prepared to make a right turn. When I accelerated to turn I heard and felt a large clunk in the rear end of my car; I thought I had been rear-ended but no other car was there. I then could feel and hear something dragging so I pulled over. I could see the rear axle hanging down on the ground and the wheel well on the driver rear buckled inward. It turned out that one of the bolts that held my rear axle in place was missing and the other one sheared off due to stress. My car literally dropped its rear axle. I have never had work done that would have entailed removing this bolt so the only assumption is that it was either loose or missing when I purchased the car. I am very thankful that it happened when I was accelerating from a stop not passing a car on the interstate!.
Rainwater leaked into the vehicle, collecting in the passenger footwell, shorting out several electrical components. I understand vw/Audi vehicles have a history of this occurring due to firewall/pollen filter/sunroof deficiencies which allow this to happen and they and their dealerships are very uncooperative in even acknowledging such a problem exists in the design of these vehicles. Very unfair to consumers to deny such a problem exists and they should be held accountable.
