De la nada el carro brinco la velocidad de 65 millas a 25 estuvimos a punto de tener un accidente, I reported the issues on 01/04/2010 to the audi company at the time of the incident they said there was no recalls, the car behind almost hit us and since them the car jumps every five minutes from normal speed to slow speed less than 30 miles in the freeway when the speed supposed to be 65 miles. I had other incidents driving in my way to my job where I need to drive 25 minutes in the freeway. *Tr

Latest 100 acceleration complaints
92 Audi 100s, stuck throttle and brake boost failure, previously reported. Found the problem and am posting it here. This can kill someone. I hope nhtsa does something. Audi usa will not. See below: found the problem. Mangled plastic debris in the throttle body that would hang up the plate intermittently. Shame on me for calling it acceleration when it was actually a stuck throttle. What I learned is that the small brief throttle stabs you do to keep going uphill or in traffic can result in very high rpms...

if the throttle sticks at max excursion. It makes you think the engine is accelerating. Shame on audi for never examining the throttle body and ignoring the problem posed by the disintegrating plastic neck on the valve I mentioned in earlier posts. The disintegration of that thin plastic neck apparently can result in simultaneous stuck throttle (from debris getting sucked into throttle body and preventing the throttle plate from returning to idle position) and loss of brake boost through the vacuum leak caused by the broken neck. Btw, the brakes would not stop the car on the last runaway (about 5500 rpm), just got it down to about 20 mph even when I was standing on them, had to shift into neutral (which took the rpms to redline and limiter) and turn off the key. That really surprised me. This problem could easily kill someone. I have notified audi usa and nhtsa but nobody has taken any action. I don't know what more I can do to prevent a tragedy. Remember, two others have reported runaway/ stuck throttles on 92 100s. Hopefully the debris would eventually get sucked out of the throttle body and chewed up in the engine, but mine didn't. It had to be found and dislodged manually. While it remains in the throttle body, it is a disaster waiting to happen. *Tr
While driving, a sudden surge in speed caused I believe bythe automatic activation of the cruise control feature on my 1992 audi cs 100. I hit my brakes, shiftedmy automatic transmission to neutral and stomped the accelerator several times until the engine stopped racing. I checked to see if the cruise control was in the off position, it was. The same thing occured several more times before I had the cruise control disconnected, after which the car drove normally.
The accelerator pedal has a plastic part connected to it when this part breaks off the entire accelerator pedal has to be replaced. *Yh
When driving and upon depressing accelerator pedal for no apparent reason vehicle will lose all power unexpectedly, causing vehicle to go into a drift due to sudden decrease in speed. Engine continued revving without any forward movement. Consumer contacted the dealer, dealer unable to determine the cause. Please provide any further details. *Ak
The car is currently not safe to drive. On june 25th I drove the car for 40 minutes on the highway. When I exited the highway, the engine would race when I came to a stop light. The brakes were applied and the car was at a complete stop, but the engine would race so that the speedometer registered 50 miles per hours. When I released the brakes to proceed through the light, the car immediately sped off at nearly fifty miles per hour. I did not apply the gas pedal at all. I had no control over the car. It was not...

shifting into lower gear. It was racing, even when the car was put into park. Since that time, I have tried to start up the car on several occasions. Every time the engine races as soon as the car is turned on. When in park the speedometer registers up to 60 miles per hour and must be immediately turned off. I cannot drive the car. I called audi to complain, but they informed me that there had not been a recall for this problem on my model. Other audi owners have told me that this problem is very common and that drivers have been seriously injured. When I first purchased the car, I brought it in because of a slight shifting problem. The car would stutter a bit before shifting gears. The dealer said they had fixed the problem. It seems as though it has only become more severe. I have only put about 10,000 miles on the car in the 2 years since I bought it. The car is well maintained. This problem seems to be a manufacturer's defect.
While driving, the accelerator pedal came apart - the complete top broke off, fell to the side and lodged behind the remainder of accelerator mechanism. Luckily, I was able to stop the car and extract it without injury. Audi claims this is normal wear and tear. They have refused to cover the repair. Why is this not a manufacturing defect?
Intermittently when slowing down the vehicle stalls and dies, resulting in loss of vehicle control. The dealer has repaired the vehicle, but the problem stills exists. *Ak dealer reset throttle position adaption and replaced the idle stabilizer valve, stalling has not occurred anymore. *Slc
