Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2001 Audi A4 Owner Comments

The "check engine" light on my 2001 Audi A4 quattro came on and was running somewhat roughly. I called the dealerships service department and they told me to bring it in. On the 8-mile freeway drive the engine caught fire and destroyed the engine.

1. both times, car was being driven normally at around 30-40 mph when, without any warning at all, the car completely stopped from it's speed to zero mph immediately, engine dies and all power was gone from the car. All attempts to restart the car were unsuccessful. It is not a battery issue. This car is very well maintained to all manufacturer's recommendations with oem parts used for all services which are all done by certified technicians at the dealer or reputable independent shop. 2. occurred first on Sunday 4/27/08 and again on 5/1/08. We are very lucky that it happened when we were on quiet subarban streets and not the highway otherwise with the car coming to a sudden and complete stop there could have been a very messy accident. Imagine going from 65mph to 0mph without any warning on a rush hour freeway. Please investigate this very thoroughly. 3. after first incident, car was taken to reputable Audi auto repair shop that replaced an electric wire, electrical connector and ignition switch. Mechanics' claim to have found power supply cable to the ECU with excessive resistance, traced the wire and found a bad connection in the harness connector. By-passed connector and now the computer is communicating ok (copied from mechanics' operations and parts report). This took the mechanics' 3 days as they said it was a very freaky, unusual and hard to find and solve electrical problem. Clearly this did not work since the car again suddenly stopped 5 hours after the alleged fix. Now have towed the car to Audi dealership. 4. after first incident, called Audi client relations U.S.a. to inform them of what we thought was a major safety risk to help make sure it did not happen to others in the future since it could lead to a very messy/fatal accident(s) but they were not at all interested since it is outside warranty.

I leased an A4 2001 Audi in December 2000. My lease runs out in March 2004 and I'm looking at what my rights are as a consumer. Over the last 6 months, I've had my car towed and repaired twice for ignition coil failure as well as my tires replaced from out of whack alignment. Today, the engine light appeared again and I will drop it off at the Audi service department, this Monday for maintenance review. Fortunately, the only costs I've incurred are replacement of the 2 front tires. It currently has 33,000 miles on it.
