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.
Filled Audi Q7 tdi 2010 model on 5/4/2011 with diesel fuel and made it about 3/4 of a mile and the vehicle started to rattle and shake hard, felt almost like a flat tire. . . . . But then started to sputter and gurgle and then shut down completely, this took all but about 60 seconds once I felt the shaking, to the shutdown. . . . . . . Steering locked. . . . Not good. . . . Almost hit a parked car on the side of the road. Vehicle died and stalled in the slow lane (for an hour) and would not restart. . . . What could have happened on a freeway. . . . I hate to think. . . . Flatbed tow truck to dealership and was advised (3) three days later that the hpfp atomized into the fuel system and the system would have to be replaced. . . . Injectors, fuel lines, fuel tank, gas filler nozzle, etc. Etc. , I have an invoice 5 pages thick for this!! well, 28 days later suzie q, as we called her, was back. Now. . Now. . Now. . . Again!! yes, again, this has happened. . . . . Wed. , January 8, 2014. . . . Almost an identical situation occurred. . . . . Filled Audi Q7 tdi 2010 model with diesel fuel and made it approx. 3/4 mile. . . . (geese what a surprise!!) and sounding so familiar. . . Yes?? just read again the previous paragraph and place it here. . . . Identical, identical, situation to the "t" this time around, except a different gas station. Dealer today, January 10, 2014 has informed me that, yes, indeed the hpfp has atomized again,. . . . Again,. . Really. I want to lemon this pos that I paid $78,510. 38 for and was touted by the dealership as almost bullet proof!! hah lol. . . I was a fool. Never again buying an Audi. . . Unless this is made right. Trade in for full value minus a little. . . . Sound ok??.
Audi 2010 Q7 tdi fuel filler problems. On several occasions, approximately 1 in 4 fuel stops (current mileage 9,200 miles), I have been unable to insert a fuel pump nozzle into the fuel filler neck on the vehicle due to a vertical bar just inside the filler opening. If fuel is dispensed, its is rejected onto the outside of the vehicle and ground. Possible fire risk. In addition, using the vehicle in urban and rural settings all over the western us, I have been low on fuel and unable to refuel the vehicle risking running out of fuel far from another station. Personal safety risk. Audi does not have any explanation for the problem yet it should be corrected. I have called the dealer and searched the web for information and/or a solution to the problem. Most recently, at a station at west yellowstone national park, I was able to overcome the locking bar with a knife and the fuel filler nozzle combined so I could release the bar and insert the fuel filler nozzle. Audi says it is due to damaged fuel pump nozzles at fuel stations but this does not hold true since it occurs at stations where nozzles are nearly new and perfectly round.
