THE VEHICLE ACCORDING TO THE AUDI DEALER HAS A BAD AUTOMATIC TCM TRANSMISSION CONTROL MODULE THAT CAUSES THE CAR TO SLIP GEARS OR NOT SHIFT DOWN WHEN COMING SLOWING DOWN AND THEN NEEDING TO ACCELERATE.

2004 AUDI A4 WITH INTERMITTENT FUEL PUMP FAILURE. ON SEVERAL OCCASIONS THE CAR WOULD STOP RUNNING WHILE DRIVING AND THEN RESTART AFTER SOME TIME. THE LATEST EVENT OCCURRED AT THE AIRPORT AND ALMOST CAUSED AN ACCIDENT. I HAD THE CAR TOWED TO A REPAIR SHOP AND IT WAS DETERMINED THAT THE FUEL PUMP WAS NOT OPERATING RESULTING IN $800 IN REPAIRS. THIS IS A DANGEROUS SITUATION AND APPEARS TO BE A LARGER PROBLEM WITH THIS VEHICLE. A RECALL OF THE 2002-2003 DID NOT CAPTURE THESE OTHER VEHICLES WHICH HAVE THE SAME PROBLEM. SINCE THIS CAN RESULT IN INJURY AND/OR DEATH, ITS CRITICAL THAT THE GOVERNMENT INVESTIGATE FOR RECALL. AUDI WILL NOT TAKE RESPONSIBILITY UNLESS HELD ACCOUNTABLE. *TR

MY VEHICLE IS A 2004 AUDI A4 CABRIOLET WITH A 1.8T ENGINE. WINDSHIELD WIPERS STOP WORKING. WHILE DRIVING ON THE PA TURNPIKE IN THE RAIN MY WINDSHIELD WIPERS STOPPED IN THE MIDDLE OF THE WINDSHIELD AND WOULD NOT MOVE. I WAS LUCKY IT WASN'T AT NIGHT BECAUSE I WAS UNABLE TO SEE THE LANES IN THE ROAD OR OTHER CARS IN FRONT OF ME. I PULLED OVER AND WAITED FOR THE RAIN TO STOP. WHEN I CONTACTED THE AUDI DEALERSHIP TO ASK WHAT THEY THOUGHT IT COULD BE I WAS TOLD THAT IT WAS MOST LIKELY CAUSED BY THE WINDSHIELD WIPER TRANSMISSION BECOMING CORRODED WITH RUST AND BEING UNABLE TO MOVE. THE SERVICE TECHNICIAN SAID THIS WAS A COMMON PROBLEM WITH THESE CARS AND THEY HAD JUST FINISHED REPAIRING ONE THIS WEEK (SOUTHHILLS AUDI, PITTSBURGH PA) I MADE AN APPOINTMENT AT THE DEALERSHIP TO HAVE MY VEHICLE INSPECTED AND 2 WEEKS LATER AFTER THE INSPECTION WAS TOLD THAT THE WIPERS HAVE DEFINITELY STOPPED WORKING BECAUSE OF THE AMOUNT OF RUST ON THE WINDSHIELD WIPER TRANSMISSION. I WAS QUOTED 600 DOLLARS TO FIX AND LEFT TO DRIVE HOME SINCE THEY DIDN'T HAVE THE PARTS. *KB
