2013 Audi S4

Transmission fail while driving and stationary at traffic light. Main DTC: P179F00 - Drive sensor position: malfunction Additional DTC: P179E00 - Drive sensor position: electrical malfunction ABS: 00473 Parking brake: U111300 TCM: 01315 This situation occurred 3 times in the past 3 weeks while driving or being stationary at a traffic light. Event triggers loud warning sounds, red flashing lights/icons in dashboard, total loss of power while engine still running. At this time, this problem creates highly dangerous driving conditions with random total loss of power. The situation is temporarily remedied if engine is shut off and restarted.

At times Vehicle suddenly loses power and displays “transmission malfunction:you may continue driving” but then fails to accelerate to or maintain highway speeds. Other times when vehicle is stopped in traffic the transmission delays engaging when pressing in the accelerator and thus causes an unexpected delay to movement or if on an incline will roll backwards.

THE PROBLEMS STARTED BY A WARNING ON MY DISPLAY SAYING TO PULL OVER GEAR BOX OR TRANSMISSION FAILURE. YOU HAVE SECONDS TO PULL OVER BEFORE THE CAR NO LONGER FUNCTIONS. EVEN THOUGH YOU ARE IN GEAR ALL THAT HAPPENS IS THE ENGINE REVS AND YOU GO NO WHERE. MY CAR HAS ONLY 38,500 MILES ON IT AND IS OUT OF WARRANTY BY A COUPLE OF MONTHS. I HAD THE CAR TUNED ADDING SOMEWHERE AROUND 100 HP 6,000 MILES BEFORE THIS HAPPENED AND AUDI SAYS THIS IS WHAT CAUSED THE ISSUE. TO FIX THE SENSOR ERROR CODE P179E00 WAS AROUND $5,000. 00 EVEN THOUGH THERE HAS BEEN A SERVICE BULLETIN OUT FOR THIS PROBLEM FOR MORE THAN A YEAR. AFTER LOOKING AROUND DECIDED TO HAVE AUDI DO THE REPAIR BUT WITHIN AN HOUR OF LETTING THEM KNOW TO GO AHEAD WITH REPAIRS THEY CALLED ME BACK AND TOLD ME THAT IT COULD BE THE WHOLE TRANSMISSION WHEN THEY TESTED THE FLUID IT CAME BACK WITH SOME METAL SHAVING IN IT. THIS WOULD BE A $12,000.00 REPAIR. THE SAFETY OF THIS TRANSMISSION IS IN QUESTION FOR THE FACT THAT THERE HAS BEEN A SERVICE BULLETIN OUT FOR THIS TRANSMISSION EVEN THOUGH AUDI OF AMERICA DENIES THAT MY VIN IS PART OF THE SERVICE RECALL. IT IS PRETTY SCARY WHEN YOU DRIVING AND THE TRANSMISSION JUST SHUTS DOWN AND YOU AND YOU CAR ARE JUST STUCK IN TRAFFIC AS CARS DODGE YOU AND FLY BY YOU AND YOU DEAD CAR.

THIS VEHICLE IS KNOWN FOR HAVING A FAULTY MECHATRONICS UNIT. THE MECHATRONICS UNIT DOES NOT WORK CORRECTLY, AND CAUSES JERKING AND INSTABILITY TO THE DSG TRANSMISSION. I HAVE ALMOST REAR ENDED OTHER VEHICLES AT RED LIGHTS BECAUSE THE TRANSMISSION WILL JERK FORWARD UNEXPECTEDLY AND LUNGE ME FORWARD TOWARD THE VEHICLE AHEAD. THIS IS NOT ONLY AN ISSUE THAT A PRESTIGIOUS NAME LIKE AUDI SHOULD NOT HAVE, BUT IT IS A HUGE SAFETY ISSUE. AUDI OF AMERICA IS AWARE OF THIS PROBLEM, BUT CHOOSES TO IGNORE IT FOR THE SAKE OF NOT HAVING TO COVER REPAIRS FOR ALL THE VEHICLES REPORTING THIS ISSUE. A SIMPLE GOOGLE SEARCH WILL YIELD RESULTS OF JUST HOW COMMON AND WIDESPREAD THIS ISSUE IS. *TR
