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…

THE VEHICLE EXHIBITS "NOTCHY" STEERING AT HIGHWAY SPEEDS, PARTICULARLY IN COLD WEATHER. AT OR ABOVE APPROXIMATELY 55 MPH, THE STEERING WHEEL TRIES TO "BOUNCE" LEFT AND RIGHT RATHER THAN MAINTAINING CENTER--EVEN WHEN TRAVELING ON A STRAIGHT, FRESHLY-PAVED SECTION OF INTERSTATE. THE DRIVER HAS TO CONSTANTLY ADJUST THE WHEEL TO KEEP THE CAR TRAVELING STRAIGHT. THE STEERING FUNCTIONS NORMALLY OTHERWISE, AND THE PROBLEM DOES NOT MANIFEST ITSELF AT LOW SPEEDS. I BEGAN TO NOTICE THE PROBLEM AROUND AUGUST OF 2020. OTHER OWNERS OF THE SAME VEHICLE HAVE REPORTED SIMILAR PROBLEMS: HTTPS://WWW.AUDIZINE.COM/FORUM/SHOWTHREAD.PHP/690756-NOTCHY-STEERING.

I HAVE ENCOUNTERED THE PROBLEM OF AIR BUBBLE FORMATION IN MY FUEL SYSTEM (CODE 16903) WHEN READING CODES IN MY CAR. I THOUGHT IT WAS JUST A FUEL PUMP ISSUE SO I REPLACED IT. I THEN REALIZED IT WASN'T JUST A PUMP ISSUE AS THE CAR KEPT READING THOSE CODES AND KEPT STOPPING. I TALKED TO A LOCAL AUDI DEALERSHIP AND SAID I WOULD HAVE TO GET THE FUEL PUMP VAPOR EXTENSION. WHEN ASKED THEY SAID THAT IT'S ONLY A TSB NOT A RECALL DUE TO IT NOT BEING A SAFETY ISSUE. NOW YOU TELL ME, MY CAR WENT INTO LIMP MODE AND STOPPED ONCE IN THE MIDDLE OF THE HIGHWAY, AND 3 TIMES IN THE MIDDLE OF TRAFFIC 2 WEEKS LATER. I BELIEVE IT'S A SAFETY PROBLEM AS ANYONE COULD'VE RAN INTO ME AND CAUSED BIGGER PROBLEMS. I…

WHILE DRIVING, STEERING CAN BECOME NOTCHY. STEERING INPUTS ARE NOT ALWAYS 100% TRANSFERRED TO THE FRONT WHEELS. THERE CAN BE A "DEAD SPOT" IN THE STEERING. THE CAR DOES NOT ALWAYS FOLLOW THE INTENDED PATH. THE PROBLEM COMES AND GOES, AND SEEMS TO BE EXACERBATED IN COLDER WEATHER.

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.

THE PASSENGER AIRBAG OFF INDICATOR LIGHT IS ON. CHECKED WITH AUDI AND THEY ARE SAYING THE PASSENGER OCCUPANT DETECTION SYSTEM NEEDS TO BE REPLACED. EAXCT SAME ISSUE AS THE AUDI RECALL 74D5

THE ENGINE MOUNTS HAVE GONE BAD. THE DEALERSHIP SAYS THEY ARE LEAKING AND THUS HAVE FAILED. THIS IS A KNOWN ISSUE WITH THIS MODEL AND SEVERAL OTHER MODELS. THE ENGINE MOUNTS FAIL AT AROUND 50000 MILES. I'VE NEVER HEARD OF ENGINE MOUNTS GOING BAD THIS EARLY IN A CARS LIFE. MAYBE AFTER 100000 MILES I WOULD EXPECT FOR THE ENGINE MOUNTS TO FAIL BUT NOT AT 50000 MILES. MANY AUDI OWNERS HAVE COMPLAINED ABOUT THIS ISSUE ON FORUMS AND AUDI GROUPS ONLINE. THIS IS A SAFETY ISSUE AND AUDI IS NOT DOING ANYTHING ABOUT THIS. THEY ARE LEAVING THEIR CUSTOMERS TO FIX A PROBLEM WHICH SHOULD NOT EXIST.
