POWER TRAIN

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.

MY 2014 AUDI S4 HAS A EPC LIGHT THAT KEEPS TURNING ON WHILE DRIVING THAT CAR. THE EPC LIGHT WILL PUT THE CAR INTO LIMP MODE AND WILL HAVE A ROUGH IDLE AND CAN BARLEY DRIVE. WHEN THAT LIGHT TURNS ON YOU HAVE TO PULL OVER IMMEDIATELY AND RESTART THE CAR TO CONTINUE DRIVING AND IS A COMPLETE SAFETY HAZARD BECAUSE IT WILL HAPPEN WHEN YOU ARE ON THE FREEWAY. THE LIGHT MAINLY TURNS ON WHEN YOU ARE TRYING TO GET UP TO SPEEDS OF THE FLOW OF TRAFFIC. I HAVE TAKEN IT TO THE DEALER MANY TIMES TO GET THIS ISSUE RESOLVED AND THEY KEEP SAYING THERE IS NO ISSUE WITH THE CAR WHAT'S SO EVER. I DECIDED TO TRY TO FIGURE OUT WHAT WAS WRONG WITH THE CAR MYSELF BECAUSE THE DEALER WAS NO HELP. WHEN I LOOK IT UP HUNDREDS OF FORUMS SHOW UP TALKING ABOUT IT AND NO ONE CAN FIGURE OUT WHAT IS GOING ON WITH THE CAR AND EVERYONE IS HAVING THE SAME ISSUE AND HOW THE DEALER IS NO HELP AT ALL. ONE PERSON SAID THEY TOOK IT TO THE DEALER AND THERE WAS A FAULTY WIRE ON THE ECU. I THINK ITS THE ECU FAILING AND DOESN'T KNOW WHAT TO DO.

CAR SLAMMED INTO DIFFERENT GEAR, WASN'T ABLE TO SHIFT INTO 2ND AND THREW GEARBOX MALFUNCTION AND TPMS ERRORS. THANKFULLY I WAS NEAR HOME AND ABLE TO MAKE IT THERE WITHOUT AN ACCIDENT OR BEING STRANDED, BUT MY CAR IS NOW IMMOBILE. I SPOKE WITH AUDI AND THEY SAID IT WILL LIKELY BE A $4K REPAIR (MECHATRONICS UNIT). AFTER RESEARCHING THIS MORE, IT SEEMS TO BE A COMMON PROBLEM WITH THESE CARS. IT CAN HAPPEN AT ANY TIME AND CAN BE EXTREMELY DANGEROUS. THERE'S ALSO A PENDING CLASS ACTION LAWSUIT TO GET AUDI TO DO THE RIGHT THING AND RECALL THESE CARS AND FIX THEM.

POWER TRAIN

WHILE TRAVELING AT 75MPH, UPHILL, IN 100F WEATHER THE FUEL LOW PRESSURE FUEL SYSTEM DEVELOPED A VAPOR BUBBLE THAT STALLED THE LOW PRESSURE FUEL PUMP AND STARVED THE MOTOR FOR FUEL. THE CAR STALLED ON THE FREEWAY AND WOULD INTERMITTENTLY RESTART UNTIL THE LOW PRESSURE FUEL PUMP FAILED. THE REPAIR REQUIRED ADDITIONAL VALVES AND HOSES HE ADDED TO THE LOW PRESSURE FUEL SYSTEM TO COMPENSATE FOR THE POOR VAPOR MANAGEMENT DESIGN. THE CAR HAD TO BE TOWED TO A DEALERSHIP WHERE THE APPROPRIATE FIX AND TSB WAS EXECUTED. TOTAL COST WAS ~$2200, $715 OF THAT TOTAL COST WERE THE NEW VALVES AND HOSES THAT SHOULD HAVE BEEN PART OF THE INITIAL DESIGN.

IT HAPPENED AGAIN TODAY DRIVING DOWN THE HIGHWAY GOING UP TO SPEED, AT ABOUT 50 MPH I GOT A "GEARBOX MALFUNCTION" ERROR MESSAGE IN THE CLUSTER AND IT WOULD NOT LET ME ACCELERATE ANYMORE, IT WAS LIKE THE CAR WAS IN NEUTRAL AND PRESSING THE ACCELERATOR PEDAL WOULD JUST REV UP THE ENGINE. THE MECHATRONICS UNIT ON THESE VEHICLES ARE FAULTY, I KNOW 2 OTHER S4 OWNERS WITH THE YEARS OF 2011 AND 2012 WHO ALSO HAD THEIR MECHATRONICS FAIL ON THEIR S4. ALONG WITH THE GEARBOX MALFUNCTION ERROR ALSO COMES "PARKING BRAKE ERROR" WHO KNOWS WHAT IN THE WORLD CAN HAPPEN WHEN THAT MESSAGE COMES UP. IS IT GOING TO SUDDENLY APPLY THE ELECTRONIC PARKING BRAKE GOING 50-70 MPH DOWN THE HIGHWAY AND CAUSE A POSSIBILITY OF A VERY BAD ACCIDENT? THE REPAIR IS VERY PRICEY FOR THE MECHATRONIC UNIT THAT GOES BAD, IT IS NO COINCIDENCE MANY OF THESE S4 MODELS HAVE THESE GO BAD.
