two SCARY sudden acceleration incidents 92 Audi 100S
Happened yesterday. Below is text of two messages I sent to NHTSA on
their complaint form. Notified AUDI US also, but no reply . I always
thought these claims were BS and from old drivers who accidentally
depressed the accelerator pedal when they thought they were pressing
the brake. It is scary, it is real and it needs to be looked into by
Audi. I skydive and I have had two main chute malfunctions that
required cutaways. I have experience in handling emergencies and not
panicking. I was NOT pressing on the gas pedal. I didnt want to shut
off the engine with the key until I was stopped as I feared losing
steering.
I looked on the NHSTA website and there have been a couple of other
complaints besides mine that were nearly identical. One guy assumed
like I did that it was a cruise control issue, but it isn't. He is
probably still driving thinking the problem has been fixed. The second
incident happened with the cruise fuse pulled.
Anyone have any ideas? The only clue was brake pedal effort seemed to
increase right before it happened, as if vacuum boost had been lost or
decreased. All ideas appreciated.
first incident:
RUNAWAY THROTTLE. UNCOMMANDED ENGAGEMENT OF CRUISE CONTROL? WOULD NOT
RESPOND TO BRAKE OR SHUTTING CRUISE CONTROL OFF ON STEERING COLUMN
STALK SWITCH. VERY DANGEROUS!!! ALMOST CAUSED A CRASH, VERY
INEFFECTIVE BRAKING WITH ENGINE TRYING TO KEEP CAR GOING AT ABOUT 55
MPH, BUT I MANAGED TO PULL OVER AND SHUT CAR OFF. I PULLED THE CRUISE
CONTROL FUSE AND PROBLEM HAS NOT REAPPEARED.
second incident:
DANGEROUS UNCOMMANDED ACCELERATION. I SUBMITTED A COMPLAINT EARLIER
TODAY THAT SAID I THOUGHT IT WAS A CRUISE CONTROL PROBLEM BUT IT ISNT.
IT HAPPENED AGAIN TODAY WITH THE CC FUSE PULLED!!! IT WAS PRECEDED BY
A FUNNY FEELING IN THE BRAKES, LIKE NOT ENOUGH VACUUM BOOST, THEN
RADICAL ENGINE ACCELERATION EVEN WITH MY FOOT OFF THE GAS PEDAL. I PUT
THE CAR IN NEUTRAL, THE TACH REDLINED AND THEN I SHUT OFF THE
IGNITION. STARTED IT AND IT DID IT AGAIN. I AM AN ENGINEER AND NEVER
BELIEVED THE STORIES ABOUT AUDIS AND UNINTENDED ACCELERATION... BUT
NOW I KNOW IT CAN HAPPEN AND IT IS SUPER DANGEROUS!!!!

Re: two SCARY sudden acceleration incidents 92 Audi 100S 2.8L V6 engine
You have the 2.8L V6 engine right Mark?
No examination after the incident? hmmm
I have seen you post before boeing377 so I do believe you. I just have not
personally seen something like this that could not be explained.
I would look at the throttle body, especially the throttle plates and their
linkage.
I have seen the throttle plates get stuck due to corrosion and lack of
lubrication. I have cleaned and lubed many throttle bodies that were
operating stiffly/slowly on the AUDIs and VWs.
I have also seen floor mats that jam the accelerator pedal down. 8^o
Had a 1985 Audi 5000S for 20 years and NEVER experienced that problem
described here.
I also seem to remember that the problem showed up just after starting the
engine and AUDI could not replicate this issue.
Still they put on a AT Selector-Shift/Brake Switch Interlock on the cars.
Was AUDI the first to do this?

Re: two SCARY sudden acceleration incidents 92 Audi 100S 2.8L V6 engine
V 6 right. I normally would have torn into things trying to find a
fault, but I want Audi US techs to look at it undisturbed, that is if
Audi US ever responds to my emails. There was no floor mat issue and
it wasn't a sticking throttle as you might expect from a dirty
throttle plate, it rapidly and radically accelerated. In the second
incident I was in 5 mph city traffic and it took off. When I put it in
neutral it was up against the rev limiter, close to 5500 rpm with both
feet up and off the pedals. In the hands of a panicked old driver this
fault can and will kill people. Somehow there may be a clue in the
reduced brake boost prior to the uncommanded acceleration incident.
Can anyone see a way that reduced or falling brake boost vacuum could
cause or be related to this?

Re: two SCARY sudden acceleration incidents 92 Audi 100S 2.8L V6 engine
Then I wonder where the engine got its air supply from.
It must have thought it was on the runway taking off to fly!
I think on your engine you have a stabilizer valve that allows more air
inside of the engine controlled by the ECM. But I am not sure of the
controls on your engine except that it should have something to allow air
inside without accelerator intervention. Sometimes my '91 Passat will have
a very high idle and I need to cycle the ign off and back on. I think I
need to replace my ECM since I have checked everything else.
Glad you think on your seat!
Please post what is found.......I am curious!
