Power Train, engine, fuel/propulsion System
06/12/2019
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 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.

Steering
12/14/2016
WHILE DRIVING MY 2014 AUDI S4 ON THE HIGHWAY AND IN TURNS, THE STEERING GOES FROM FEELING TIGHT TO VERY LIGHT AND BACK TO TIGHT AGAIN WITHIN A MATTER OF SPLIT SECONDS. THIS CAUSES DRIFTING ON THE HIGHWAY AND WHEN CORNERING BECAUSE YOU'RE COMPENSATING FOR THE LACK OF FEELING FOR AN INSTANT AND USING MORE INPUT THAN YOU SHOULD, THEN THE STEERING GETS TIGHT AGAIN AND YOUR CAR STEERS MORE THAN IT SHOULD HAVE. NOTE THAT THE CAR GOES STRAIGHT WHEN HANDS ARE NOT ON THE WHEEL. THIS IS MOST PREVALENT AT TIMES WHEN THE STEERING WHEEL IS IN THE STRAIGHT POSITION. THIS SEEMS TO BE DUE TO THE MOVEMENT OF THE STEERING WHEEL THAT HAPPENS UNDER THE FORCE OF THE DRIVERS HANDS AS THE STEERING ASSIST LEVEL FLUCTUATES. THE CAR DOES NOT WANT TO STAY CENTERED WHEN GOING STRAIGHT AND HANDS ARE RESTING ON THE WHEEL. THERE SEEMS TO BE EXCESSIVE ASSIST AT OR NEAR THE TOP DEAD CENTER. NOTE THAT THIS IS AN INTERMITTENT ISSUE. IT MIGHT BE DRIVING FINE, THEN I TURN OFF THE ENGINE TO FILL UP WITH GAS FOR...
