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.

Lost acceleration, would not take any throttle input. Started to slow down, epc lite came on an started flashing. Speed continued to drop for the next 10 miles. Got off at the first exit that came up on the I5. As I came off the fwy I was down to 25 mph. At the first lite I had to stop, the engine quit, I then turned right it was down hill so the car glided with no power steering or brakes. Made it into a parking lot to a safe place to park. Car would not restart. Had it taken by flat bed to our Audi dealership 107 miles away. Dealer said that the high pressure fuel pump failed and contaminated the complete fuel system.

Tdi high pressure fuel pump failure while accelerating from red light. This resulted in loss of power steering, power brakes and steering wheel locked while pulling car over. Had car been traveling at high speed or less experienced driver it would have resulted in an accident.

Q7 6-cyl Diesel

  • 30,000 miles
This is a tdi version of the Q7. The high pressure fuel pump failed during normal use and sent metal parts through the fuel lines, through the fuel filter and into the combustion chambers. As a result, the engine ceased and we were left stranded in the middle of the road on a winding canyon road. The engine block was damaged; the crank shaft bent, the pistons damaged the heads and many other parts were destroyed. The car was repaired by an Audi dealer and required all new fuel components (bumper to bumper) and a new engine. The car was in the shop for over a month.
