2010 AUDI S4 Power Train Problems

Unknown

ONCE CAR IS PUT INTO REVERSE IT LAUNCHES BACK ? ALSO IN FIRST ONE PUT IN COST IT WANTS TO MOVE PRACTICALLY FORWARD .

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.

HAD TO HIT FLASHERS AND COAST INTO MEDIAN. WAS ALMOST HIT BY SEMI TRUCK. REPAIR SHOP COULD NOT FIND ANYTHING WRONG. HAPPENED AGAIN 1 DAY AFTER GETTING IT BACK FROM SHOP. TAKING IT TO AUDI NOW. I HAVE READ THAT THIS IS A COMMON PROBLEM.

MECHATRONIC ISSUES.

Mileage: 79,000

THE WHOLE CAR JERKED WHEN GOING TO 2ND GEAR AND THEN THETPMS, NO REVERSE, AND GEAR MALFUNCTION LIGHTS COMES ON. 2ND, 4TH, 6TH, AND REVERSE GEAR ARE GONE. RESTARTING THE CAR CLEARED THE WARNING AND DROVE FINE FOR 10 MILES BEFORE IT HAPPENS AGAIN. TRY RESTARTING AGAIN TO CLEAR THE WARNING BUT LIGHT WILL COME BACK ON WHEN GOING TO 2ND OR REVERSE.

Mileage: 72,000

GEARBOX FAILURE SEEMS TO BE COMMON ISSUE ON THE 2010 MODEL. SEEMS A REPLACEMENT MECHATRONICS UNIT OR FULL TRANSMISSION WILL NEED TO BE DONE TO RESOLVE THE ISSUE.

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.

Mileage: 67,455

VEHICLE WAS IN MOTION, THE MECHATRONICS UNIT ON MY CAR IS FAILING AND JUST MANY MANY OTHER VEHICLES OF THE SAME MAKE, MODEL, AND YEAR. THE VEHICLE CAN STOP ENGAGING GEARS AT ANY SPEED AND CAN BE VERY DANGEROUS AT ANY SPEED, ESPECIALLY ON THE HIGHWAY

Mileage: 67,320

TRANSMISSION FAILURE. LURCHING FROM A STOP AND LURCHING DURING SHIFT CHANGES.

Mileage: 109,000

VEHICLE WAS AT A STOP AT A TRAFFIC LIGHT WITH BRAKE ENGAGED AND VEHICLE SUDDENLY ENGAGED INTO GEAR AND TRIED TO SURGE FORWARD. HAD TO PUT THE TRANSMISSION INTO NEUTRAL TO DISENGAGE GEAR. IN OTHER INSTANCES, VEHICLE WILL SLAM INTO GEAR ABRUPTLY WHEN ACCELERATING FROM A FULL STOP, AND ALSO LUNGES FORWARD UNPREDICTABLY. THESE INCIDENTS ARE ALL RELATED TO A FAILING AUTOMATIC DSG TRANSMISSION.

Mileage: 125,000

GEARBOX MALFUNCTION AND TPMS MALFUNCTION WHILE DRIVING ON THE ROAD WITHIN THE CITY ABOUT 45MPH I FELT A SLIGHT JERK AND IMMEDIATELY FOLLOWING THE WARNINGS CAME ON IN THE DASHBOARD "TIRE PRESSURE! SYSTEM MALFUNCTION" & "GEARBOX MALFUNCTION: NO REVERSE GEAR (YOU CAN CONTINUE DRIVING)" THROTTLE RESPONSE WAS OFF AND FORCED ME TO IMMEDIATELY PULLER OVER! WHILE STOPPED I RE-STARTED THE VEHICLE AND THE WARNINGS WENT AWAY, I SAT THERE FOR A COUPLE MINUTES AND THEN CONTINUED DRIVING. FEW MILES DOWN THE ROAD THE VEHICLE JERKED AGAIN AND WARNINGS CAME BACK ON, I NEEDED TO GET TO WORK SO I CONTINUED DRIVING; THE CAR WOULD TAKE VERY LONG TO SHIFT GEARS AND IT WOULD JUMP FROM 1ST TO 3RD, FROM 3RD TO 5TH AND 5TH TO 7TH GEAR JERKING KIND OF VIOLENTLY EVERY-TIME AND THROTTLE RESPONSE BETWEEN SHIFTS WAS VERY LETHARGIC TO THE POINT THAT THE VEHICLE WOULD SLOW DOWN SEVERELY AND I FELT UNSAFE DUE TO CARS GETTING REALLY CLOSE TO MY REAR AND THEM HAVING TO SLOW DOWN DRASTICALLY WHILE THE CAR SHIFTED GEARS. DUE TO THE NUMBER OF COMPLAINTS I STRONGLY FEEL THAT AUDI SHOULD BE LIABLE AND HELD ACCOUNTABLE FOR ALL REPAIRS NECESSARY AND ACCIDENTS THAT THIS ISSUE CAN CAUSE. IF THIS ISSUE WOULD OF PRESENTED ITSELF WHILE TRAVELING AT 75MPH ON THE HIGHWAY I BELIEVE IT COULD OF BEEN A CASE OF LIFE & DEATH. AUDI IS PUTTING THE PEOPLE DRIVING THEIR VEHICLES AND OTHERS AROUND AT RISK BY NOT RECALLING AN UNIT OR UNITS KNOWN TO CAUSE PROBLEMS.

GEARBOX MALFUNCTION

Mileage: 65,000

AUDI 7SP DL501 'S-TRONIC' TRANSMISSION FOR: 2010-2015 AUDI S4 AND S5, 2013-2015 AUDI RS5, S6 AND S7. VEHICLES EXPERIENCE MECHATRONIC UNIT FAILURE AND CLUTCH FAULTS. RESULTING IN: SUDDEN SHAKING AND VIOLENT 'JUDDERING,' HESITATION FROM THE CAR WHEN PRESSING THE GAS PEDAL, A 'SURGE' FORWARD THAT FEELS LIKE THE CAR HAS BEEN REAR-ENDED, AND HARD DOWNSHIFTING OR CLUNKING WHEN SLOWING DOWN OR DRIVING AT SLOW SPEEDS. ALSO CLUNKING AND TROUBLE SHIFTING GEARS, DIFFICULTY ENGAGING INTO DRIVE OR REVERSE. VEHICLE SHOWING "GEARBOX MALFUNCTION, YOU CAN CONTINUE DRIVING" "GEARBOX MALFUNCTION, DO NOT CONTINUE DRIVING" VEHICLE GOING INTO "LIMP MODE" IN ANY DRIVING SITUATION. CLUTCHES NOT ENGAGING PROPERLY, SLIPPING BETWEEN GEARS. ISSUES CAN OCCUR WHILE TRYING TO ACCELERATE, MERGING INTO TRAFFIC, DRIVING UP A HILL, SHIFTING GEARS AT A LOW SPEED. MY EXPERIENCE: WHILE SWITCHING VEHICLES IN DRIVEWAY, VEHICLE WHEN INTO REVERSE AND I BACKED UP, THEN STOPPED, PUT TRANSMISSION INTO DRIVE AND AFTER A JOLT FORWARD, VEHICLE FELT LIKE IT STALLED, HOWEVER ENGINE WAS STILL RUNNING, BUT NO FORWARD GEAR, (EPC LIGHT ILLUMINATED) VEHICLE THEN ROLLED BACKWARDS INTO PARKED VEHICLE, BUT COULD HAVE BEEN CATASTROPHIC HAD IT JUMPED BACK INTO DRIVE AS 3RD CAR, FATHER, AND GARAGE WERE IN FRONT PATH. 2ND TIME: VEHICLE COULD NOT REVERSE,(EPC LIGHT ILLUMINATED) RAN INTO PARKING CURB WHILE EXPECTING TO GO BACKWARDS. 3RD TIME: AFTER FINALLY GETTING OUT OF THE PARKING SPOT (RESTARTING CAR FOR THE 4TH TIME AND EPC LIGHTS) PUT INTO DRIVE, VEHICLE SURGED FORWARD, THEN TRANSMISSION DISENGAGED,(EPC LIGHT ILLUMINATED) LEAVING ME AND VEHICLE VULNERABLE FOR REAR COLLISION,WITH LEG OUT OF THE DOOR I WAS ABLE TO PUSH AND COAST MY VEHICLE OUT OF THE WAY, JUST TO MISS BEING REAR ENDED, AS CAR WOULD NOT ENGAGE IN DRIVE AFTER 3 ATTEMPTS OF CYCLING IGNITION.

Mileage: 98,000

VEHICLE'S TRANSMISSION BECAME NON-OPERATIONAL WHILE DRIVING ON THE HIGHWAY. THIS WAS DUE TO MULTIPLE FAILED SENSORS IN THE "S TRONIC TRANSMISSION INTEGRATED SENSORS" MODULE. EARLY SENSOR FAILURE HAS BEEN A KNOWN ISSUE AS AUDI ISSUED TSB 35 12 08 2032211/1 ON DECEMBER 21, 2012 (ONLY 3 YEARS AFTER ORIGINAL MODEL PRODUCTION BEGAN) OUTLINING THE PROBLEM. THE FAILURE CAUSES AN OBVIOUS SAFETY HAZARD AND NO RECALL HAS BEEN ISSUED.

Mileage: 62,148

MY S4 THREW THE "GEARBOX MALFUNCTION, REVERSE DISABLED" AS WELL AS A TPMS ERROR CODE WHILE IN TRAFFIC, AND WENT INTO LIMP MODE AND WOULD NOT ALLOW ME TO ACCELERATE. VERY DANGEROUS, AND INCONVENIENT. LIMPED HOME AT VERY SLOW SPEED WHILE TRANSMISSION CLUNKED AND STRUGGLED TO CHANGE GEARS. THE CODE HAS GONE AWAY SINCE I RESTARTED THE VEHICLE, AND NOW IT LUNGES FORWARD WHEN YOU'RE COMING TO A STOP, WHICH MAKES YOU FEEL LIKE YOU'VE BEEN HIT FROM BEHIND. TAKING OFF FROM A STOP IS BOUNCY AND SUPER JERKY. IF I HESITATE BEFORE ACCELERATING FROM A STOP, IT WILL SOMETIMES GO SMOOTHLY. THE ENGINE RPM'S SURGE WHILE COASTING TO A STOP, OR GOING DOWN, HILL ESPECIALLY WITH FOOT OFF THE PEDAL.

Mileage: 83,380

WHEN DRIVING IN REGULAR DRIVE BOX INDICATOR COMES ON. SAYING GEARBOX MALFUNCTION LIMITED FUNCTION. I ONLY HAVE 63125 MILES AND KEEP MY CAR MAINTENANCE.

MY S4 LUNGES AT STOPS, OR IT FEELS LIKE I'VE BEEN HIT FROM BEHIND. TAKEOFF FROM A STOP IS BOUNCY, BOUNCY REVERSING, ESPECIALLY UPHILL. IF I TAKE MY FOOT OFF THE BREAKS AND HESITATE BEFORE ACCELERATING, SOMETIMES IT'S SMOOTH. THE TAC BOUNCES WHILE COASTING TO A STOP, OR GOING DOWN HILL WITH FOOT OFF THE PEDAL. THESE ISSUES HAVE BEEN INTERMITTENT THE LAST SEVERAL YEARS, BUT ARE NOW MORE PROFOUND. I'VE TAKEN THE CAR TO MY LOCAL DEALER SEVERAL TIMES TO NO AVAIL. VERY FRUSTRATING TO PAY 50K FOR A CAR THAT DRIVES LIKE THIS, WHILE AUDI PRETENDS IT'S NOT A PROBLEM. LOTS OF THESE ISSUES IN VARIOUS FORUMS.

THERE IS A TSB FOR THIS WARNING ON THIS ISSUE FOR SEVERAL YEARS OF AUDIS. AUDI WILL NOT COVER ANY OF THE COSTS TO REPAIR ALTHOUGH THEY REALIZE THIS IS A COMMON FAILURE AMONG THIS VEHICLE. THIS IS A MANUFACTURER ISSUE!! WHY ARE THEY NOT BEING HELD ACCOUNTABLE?

AT APPROX 55K MILES, MECHATRONICS UNIT FAILED. EXTREMELY ROUGH SHIFTS FROM 1-2 AND 2-1, LURCHING FORWARD AFTER COMING TO COMPLETE STOP. DEALERSHIP REPLACED MECHARONICS UNIT. AT 74K MILES ENTIRE DSG GEARBOX FAILED, WHILE ON HIGHWAY WITH VIRTUALLY NO POWER OR ABILITY TO ACCELERATE. LUCKILY TRAFFIC WAS AT NEAR STOP DUE TO RUSH HOUR, WAS ABLE TO MAKE IT TO NEXT OFFRAMP IN WHAT THEY CALL 'LIMP MODE'. DEALERSHIP IS REPLACING ENTIRE TRANSMISSION.

Mileage: 74,500

THE S-TRONIC/DSG TRANSMISSION IS HAVING ISSUES DOWNSHIFTING. IT WILL REV UP HIGH WHEN COMING TO A STOP AS WELL. THERE IS ALSO A HARSH CLUNK WHEN SHIFTING FROM NEUTRAL-DRIVE-PARK. AUDI RECOMMENDED REPLACING THE MECHATRONICS UNIT IN THE TRANSMISSION. THE MECHATRONICS CIRCUIT BOARD HAS ALREADY BEEN REPLACED AT OWNERS COST AND NOW THEY WANT ME TO REPLACE THE ENTIRE MECHATRONIC UNIT AT MY COST ($3800+). THIS IS A COMMON ISSUE WITH THESE CARS AND THERE NEEDS TO BE A RECALL FOR THESE TRANSMISSIONS. IT IS KNOWN THAT THESE TRANSMISSIONS ARE FAULTY AND AUDI DOES NOT WANT TO TAKE RESPONSIBILITY FOR THESE ISSUES.

Mileage: 70,000

SYMPTOMATIC DSG ENGAGEMENT ISSUES. BRAKING DOWN TO 0 MPH FROM GEARS ABOVE 1ST WILL HOLD THE GEAR UNTIL THE LAST SECOND BEFORE TOTAL STOP WHERE IT FEELS THE CAR IS REAR ENDED AND LOUD BANG IN THE TRANSMISSION.

I HAVE JUST RECENTLY PURCHASED THIS CAR FROM AN OLDER MAN WHO WAS VERY KIND TO THE CAR. I HAVE HAD THIS VEHICLE FOR THE WHOLE TWO MONTHS WHEN I ENTERED MY GARAGE TO LEAVE FOR THE DAY I RECEIVED A"GEAR BOX MALFUNCTION, YOU MAY CONTINUE DRIVING: LIMITED FUNCTIONALITY CODE" I HAVE DONE MY HOURS OF RESEARCH AND HAVE FOUND OUT THIS IS A SIMPLY A PROBLEM LOT OF PEOPLE ARE HAVING. THIS IS SOMETHING AUDI IS SELLING ON THEIR CARS KNOWING THESE HAVE ISSUES!!!!! I WANT TO TAKE FURTHER ACTION, AUDI SHOULD STEP UP AND REPAIR ALL THE BROKEN UNITS THEY HAVE BEEN SELLING. THESE UNITS HAVE GIVEN 95 PERCENT OF AUDI OWNERS PROBLEMS. REALLY MAKES ME FEEL LIKE I'LL NEVER BUY ANOTHER. *TR

Mileage: 94,200

I WAS DRIVING AND CAME UP TO STOP LIGHT. CAR FLASHED UP WARNING SAYING GEARBOX MALFUNCTION LIMITED FUNCTIONALITY. CAR WOULD NOT CHANGE UP OR DOWN SMOOTHLY OR QUICKLY. LOSS OF POWER ON EVERY SHIFT FOR OVER A SECOND. HAD AUDI OF STEVENS CREEK CHANGE DSG FLUID A COUPLE OF WEEK PRIOR. *TR

Mileage: 54,000

THE DSG TRANSMISSION IS VERY JERKY IN 1-2 GEARS IT OPERATES AS THOUGH THE CLUTCH IS NOT ENGAGING/DISENGAGING PROPERLY. WHEN TRAVELING AT HIGHWAY SPEEDS WITH THE CRUISE CONTROL ENGAGED THE ENGINE RPMS WANDER AS THOUGH THE CLUTCH IS ENGAGING AND DISENGAGING. STARTING FROM A DEADSTOP OR DRIVING AT LOW SPEEDS ARE VERY UNCOMFORTABLE DUE TO THE JERKY-NESS. *TR

WHILE DRIVING IN RUSH HOUR BUMPER TO BUMPER TRAFFIC THE 2010 AUDI S4 WITH THE DSG S-TRONIC TRANSMISSION BECOMES VERY JERKY, CAUSING IT TO SURGE WHEN STARTING AND STOPPING OR DRIVING AT LOW SPEEDS. AS A RESULT IT IS HARD TO CONTROL, ESPECIALLY IN TIGHT TRAFFIC, PARKING AREAS, OR AROUND PEDESTRIANS. ADDITIONALLY, WHEN COMING TO A COMPLETE STOP WHEN IN THIS CONDITION THE SHIFT FROM 2ND GEAR TO FIRST HAPPEN IN SUCH A WAY THE IT GIVE THE FEELING THAT THE CAR HAS BEEN REAR ENDED. *TR

Mileage: 48,000

I WAS DRIVING ON A NORMAL STRETCH OF FLAT HIGHWAY APPROXIMATELY 65MPH AND THE DASH LIT UP LIKE A CHRISTMAS TREE OUT OF THE BLUE. CAR INDICATED REVERSE GEAR NOT AVAILABLE, TRANSMISSION WARNING LIGHTS, AND TIRE PRESSURE MONITOR SYSTEM PROBLEM ALL AT THE SAME TIME. CAR WENT IN TO A "LIMP MODE" AND IT ONLY SHIFTED IN EVEN NUMBER GEARS, AND FELT LIKE THE CAR WAS DANGEROUSLY UNSTABLE DUE TO ERRATIC MISSED SHIFTING. THE CAR HAD RECENTLY BEEN IN PRIOR FOR A SERVICE CHECK AND HAD NO CODES OR CHECK ENGINE LIGHT PROBLEMS AT ALL! AFTER A LITTLE RESEARCH IT IS A WELL DOCUMENTED PROBLEM THAT THE MECHATRONICS FAILS ON THIS VEHICLE RATHER OFTEN. THAT WAS THE PROBLEM. COST OF REPAIR WAS NEAR 3300$. I WAS APPROXIMATELY 4K MILES OUT OF WARRANTY WHEN THIS OCCURRED, AFTER NUMEROUS PERSISTENT EXCHANGES WITH AUDI OF AMERICA THEY FINALLY DECIDED TO COVER THE FAILURE AS I WAS CONSIDERING SEEKING LEGAL ACTION. ( I HAD THE PART IN HAND AND COULD SUBMIT IT TO FAILURE ANALYSIS ENGINEERING FOR CAUSE). ON AN POLL ON A POPULAR AUDI WEBSITE, APPROXIMATELY 15% OF THESE MECHATRONICS HAVE FAILED. THE DESIGN ISSUE IS A CIRCUIT CARD EMBEDDED IN HOT TRANSMISSION FLUID THAT AFFECTS THE HYDRAULIC CONTROL OF THE TRANSMISSION. IF THE TRANSMISSION IS DAMAGED IT CAN BE OVER A +10K$ REPAIR. *TR
