2011 Audi A3 problems

“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).”

“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.”

“COOLANT PUMP- AUDI ACTION CODE-19L2-"THE COOLANT PUMP MAY DEVELOP A SMALL LEAK OVER TIME." MY AUDI SUFFERED A COOLANT LEAK AND HAD TO FIX FOR $1100 IN DIAGNOSIS/REPAIRS. I REPAIRED IT ON MY OWN AND LATER I LEARNED THAT THERE WAS A RECALL FROM AUDI. I NEED TO GET MY REIMBURSEMENT FOR THE MONEY I PUT UP TO FIX COOLANT LEAK.”

“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…”

“MY A3 2011 AUDI 2.0 TDI DIESEL WOULD NOT START IN A PARKING LOT. NOT THE BATTERY: TOWED TO THE DEALER. THE DEALER IN HONOLULU,HI SAYS I NEED THE ENTIRE FUEL SYSTEM ( TANK,LINES, 2 FUEL PUMPS ) REPLACED DUE TO 'GLITTER LIKE' PARTICLES IN THE FUEL LINE. FUEL IS BEING SENT FOR ANALYSIS. I AM USING THE RECOMMENDED BRAND OF DIESEL FUEL ( SHELL ) . FORTUNATELY I WAS NOT MOVING. SEVERAL OTHER COMPLAINTS LIST SUDDEN ENGINE FAILURE DUE TO FUEL PUMP FAILURE. ALSO FORTUNATELY, IT IS STILL UNDER WARRANTY. *TR”

“INTERMITTENT FAILURE OF EXTERIOR LIGHTS TO INCLUDE HEADLIGHTS, TURN SIGNAL LIGHTS, AND BRAKE LIGHTS DURING DRIVING. THE FIRST OCCURRENCE WAS AT NIGHT. FAULT SEEMS TO BE (ENGINE) TEMPERATURE DEPENDENT (I.E. - DOES NOT SEEM TO OCCUR WHEN ENGINE BAY IS COLD). ISSUE CONTINUED TO OCCUR INTERMITTENTLY FOR SEVERAL DAYS (UNTIL THE PARTS IN THE FOLLOWING DESCRIPTION WERE REPLACED). THE PLASTIC HOUSING FOR A 30 AMPERE FUSE (POSITION F16) IN THE ENGINE COMPARTMENT WAS PARTIALLY MELTING. THE MELTED FUSE RESIDUE WORKED ITSELF INTO THE FUSE BOX TERMINALS (CAUSING DAMAGE OF THE FUSE BOX) AND CAUSING A FAULTY CONNECTION WHICH IN TURN CAUSED THE INTERMITTENT FAILURES OF THE EXTERIOR LIGHTS. I HAVE ATTACHED PICTURES OF THE F16 (POSITION) 30 AMPERE FUSE SHOWING ITS PARTIALLY MELTED PLASTIC BODY AND THE FUSE HOLDER BLOCK (ALSO WITH PARTIALLY MELTED CONTACT POSITION / TERMINAL AREA). UPON FURTHER INVESTIGATION, THE FAULT IS EXACTLY THE SAME AS A CURRENT NHTSA CAMPAIGN ID 13V569000 FOR A VW (A SISTER COMPANY OF AUDI) IN BOTH THE FUSE LOCATION AND ITS AFFECTS. IT'S NOT UNCOMMON FOR VW AND AUDI TO USE SAME PARTS. FAILURE OF EXTERIOR LIGHTS (ESPECIALLY AT NIGHT) IS EXTREMELY HAZARDOUS.…”
