MY SON WAS DRIVING MY 2011 AUDI A3 TDI TO THE GYM AT NIGHT WHEN HE CALLED ME THE CAR WOULD NOT ACCELERATE AND HAD A WARNING LIGHT COME ON. I TOLD HIM TO GOOGLE IT AND HE FOUND OUT IT WAS A GLOW PLUG INDICATOR. I TOLD HIM TO CONTINUE DRIVING IT IN THE LIMP MODE. THE CAR DIED WHILE MOVING AND MY SON WAS ABLE TO COAST INTO A PARKING LOT. THIS COULD OF BEEN A DIFFERENT STORY ON A BUSY INTERSTATE. I HAD TO PICK HIM UP AND HAD THE CAR TOWED IN THE MORNING. TO FIND OUT THIS CAR IS NOTORIOUS FOR CATASTROPHIC HIGH PRESSURE FUEL PUMP FAILURE AND THAT IS EXACTLY WHAT HAPPENED. WHEN I SAY CATASTROPHIC, METAL IS SHREDDED AND GOES INTO THE INJECTORS AND CONTAMINATES EVERYTHING THAT CARRIES FUEL. IT IS ABOUT A 7K TO 8K REPAIR. I HAVE USED NOTHING BUT LOW SULFUR DIESEL. IT'S RIDICULOUS A RECALL HASN'T BEEN ISSUED TO PREVENT THIS ISSUE. SINCE THIS HAPPENED I HAVE FOUND COMPLAINTS SCATTERED THROUGHOUT THE INTERNET.

answering questions above: -body control module fuse, possibly engine comopartment fuse box itself -intermittent exterior lighting outages -no dealer / independent service center has inspected -not been inspected by anyone -no warnings, just bulb-out warnings once the issue started longform description: Last week, I was experiencing intermittent light outages on the right side of my car (2011 audi a3 TDI) . It started wednesday 3/22, during my morning commute to work, when I was exiting highway and turned on my right turn signal all the exterior lights on the right side of my car started flickering, and stopped. Same thing happened the next morning, except worse, applying my brakes would disable my right headlight. I stopped driving until the weekend when I drove over to get my car scanned for errors by a buddy of mine who has a diagnostic tool. It pointed to the body control module. With the car on, he gave the body control module fuse a light wiggle, and smoke started pouring out. He turned the car off and took out the fuse, one of the contacts melted into two pieces, and the plastic housing the fuse is full of bubbles. It seems that the engine fuse box for this car is poorly designed, and audi knows this as they've updated the part, but no recall was started. A recall was initiated for a similar issue on Tiguans manufactured around the same time (Recall no. 13V569000). Crazy to think that while I was driving around, there could have been smoke pouring out of my engine compartment fuse box, seems pretty dangerous. And I'm not the only one as people online call this the "infamous audi/vw melted fuse box issue".

ESP malfunctioned while driving on highway: tires braked several times rapidly on one side without warning, making car difficult to control. Immediately took foot off gas and had to steer out of a small fishtail. At the time I was driving at normal speed, not cornering aggressively or anything, on a smooth dry road. In heavy traffic or on a wet road this could have resulted in a crash. On just a couple occasions shortly before this occurred, while going around corners at highway or near-highway speeds there was a sensation that the steering direction suddenly "slipped" a notch, with a sort of thunk from the tires. At the time I attributed it to unseen road bumps, but after experiencing the more serious failure I realized it was the same asymmetrical braking just on a smaller scale. No warning lights gave any indicator of this dangerous sensor fault. During the most serious incident, the ESP light flickered briefly but that is the only time any lights appeared at all. I would expect this system to "fail safe" by deactivating, rather staying active and risking loss of control. Dealer garage said the problem "might" be the ESP sensor yaw rate sensor (G202) but can't guarantee that will fix it. I found several reports online of others experiencing loss of control due to Audi A3 ESP malfunction: 1) https://www.audi-sport.net/xf/threads/esp-driving-me-nuts.225172/ 2) https://www.audi-sport.net/xf/threads/yaw-sensor-g202-replacement-location.350445/ 3) http://www.vask.org.nz/index.php?topic=41577.0

Airbag warning light came on. Dealer said passenger seat occupancy sensor must be replaced, at cost of $1500-3000 since it's 5 months past my warranty. Numerous Audi models from 2012 onward have a recall for this sensor, but not my 2011 model (yet). Other automakers have extended their warranty for this safety-critical part -- BMW to 15 years, for example. Technicians could not tell me if the sensor error means all airbags are disabled, passenger airbag only is disabled, or passenger airbag is always-on (dangerous for children).

I RECENTLY STARTED TO USE THE BACK PART OF THE CAR, NEVER HAD USED IT BEFORE HAD ANOTHER CAR FOR DOGS AND BIKES. THE AREA WHERE THE SPARE TIRE IS MADE OUT OF CARDBOARD, WILL NOT HOLD 125 LAB DOG OR A BIKE. WENT TO DEALER SAID THEY WOULD REPLACE THE PIECE AND SPLIT THE COST. PIECE IS NOT BROKEN, 1/2 THE CAR IS NOT USABLE, IF I PUT MY 125 LAB BACK THERE SHE WOULD FALL INTO THE SPARE TIRE. AUDI DOES NOT THINK THIS IS A PROBLEM. IT IS DANGEROUS TO HAVE KIDS, BIKE OR DOGS BACK THERE. UNSAFE. I HAVE BEEN EMAILING AUDI CORPORATE AND DEALER- LOTS OF TALK AND NO SOLUTIONS. THE CAR IS WONDERFUL, THEY JUST FELL ASLEEP WHEN THEY MADE THE TRUNK AREA. DANGEROUS!! *TR
