2009 Audi A3 Power Train

THE WIRING HARNESS OF A TEMPERATURE SENSOR IN THE DSG MAY HAVE CONNECTOR WIRES THAT WERE INSUFFICIENTLY CRIMPED BY THE CONNECTOR SUPPLIER DURING A LIMITED PRODUCTION PERIOD. WITH INSUFFICIENTLY CRIMPED CONNECTOR WIRES, A TEMPERATURE SENSOR HAS THE POTENTIAL TO FALSELY DETECT A HIGH GEARBOX OIL TEMPERATURE, CAUSING THE CLUTCH TO OPEN AND CAN CAUSE THE DRIVER TO PERCEIVE THAT THE TRANSMISSION HAS SHIFTED INTO NEUTRAL. IF THIS HAPPENS, THE SELECTOR LEVER POSITION INDICATOR WITHIN THE INSTRUMENT PANEL WILL FLASH. IN ADDITION, THE DEPRESS BRAKE PEDAL INDICATOR LIGHT WILL BE ILLUMINATED, ALERTING THE DRIVER TO APPLY THE BRAKES. IN HEAVY TRAFFIC, THIS COULD LEAD TO A CRASH WITHOUT WARNING.

DRIVING 30 MINUTES INTO THE HIGHWAY, THE VEHICLE DECIDED TO SHIFT INTO NEUTRAL WHILE THE VEHICLE WAS IN "D" DRIVE AND IN MOTION. THE "PRNDS" STARTED FLASHING ON MY DASH, WHILE NOT LETTING ME ACCELERATE GOING 65MPH. I HAD TO QUICKLY SLOWDOWN, AND PULL OVER TO THE EMERGENCY LANE. THE VEHICLE SEEMS TO HAVE GONE INTO "LIMP MODE". AFTER TURNING OFF THE VEHICLE AND TURNING IT BACK ON, IT DROVE JUST FINE. THIS HAPPENED ONCE MORE 2 DAYS AGO. SEEMS LIKE IT COULD BE THE TRANSMISSION CONTROL UNIT, HOWEVER DEALER CANT DETERMINE THE FAULT WITHOUT A CODE. SCARED TO DRIVE THE VEHICLE NOW.

TRANSMISSION GOES INTO NEUTRAL WHILE AT HIGHWAY SPEEDS. ENGINE RPMS JUMP TO REDLINE WHILE CAR IS IN NEUTRAL, THEN GOES BACK INTO GEAR. HAS HAPPEN SEVERAL TIMES WHILE ON THE HIGHWAY. TRANSMISSION ALSO KICKS DOWN TO LOWEST GEAR WHEN COMING AT STOP, JERKING THE CAR WHILE BRAKING.

WHILE IN DRIVE AND STARTING TO ACCELERATE IN A TRAFFIC LIGHT THE TRANSMISSION GOT STUCK IN A GEAR WHILE MAKING A TURN. PRDNS LIGHTS STARTED FLASHING AND SUDDENLY WHEN IN TO NEUTRAL. IT HAS HAPPEN SEVERAL TIMES NOW WHERE I GO FROM PARKING TO REVERSE AND THEN DRIVE. ALL PRDNS START FLASHING AND CAR DOES NOT RESPOND TO ANY GEAR.

WHEN IN LOW GEARS, EVERY ACTION (DECELERATION AND ACCELERATION) ARE EXTREMELY "JERKY". WHEN COMING TO A STOP AUDIBLE "CLUNK"S CAN BE HEARD FROM THE ENGINE AREA, AND WHEN ATTEMPTING TO FULLY STOP THE CAR JERKS FORWARD INTO FIRST GEAR. THE REVERSE AND DRIVE GEARS ON THE AUTOMATIC TRANSMISSION SOMETIMES PARTIALLY ENGAGE, OR DO NOT FULLY ENGAGE AT ALL. ON HILLS, THE TRANSMISSION HAS THESE ISSUES AS WELL.

CAR WOULD NOT GO INTO GEAR, TRANSMISSION FROZE UP. ALL THE GEAR LIGHTS WERE FLASHING PRND. HAD TO HAVE IT TOWED TO DEALER. THEY STATED THAT THE MEGATRONIC TRANSMISSION MODULE HAD TO BE REPLACED AND THE PART NEEDED TO COME FROM EUROPE. *JS

TL* THE CONTACT OWNS A 2009 AUDI A3. THE CONTACT STATED THAT THE REAR DIFFERENTIAL FAILED WHILE TRAVELING 60 MPH. THE FAILURE FELT AS IF THE BRAKES HAD ENGAGED INDEPENDENTLY. THE VEHICLE WAS STILL ABLE TO BE DRIVEN, BUT THE VEHICLE RAN WOULD DRIVE ROUGHLY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DETERMINED THAT THE REAR DIFFERENTIAL NEEDED TO BE REPLACED. THE FAILURE AND THE CURRENT MILEAGE WAS 75,000. *TR

TRANSMISSION PROBLEM. MECHATRONIC CONTROLLER HAS GONE BAD. INTERMITTENT PROBLEM. DSG WILL NOT ENGAGE TO GO INTO REVERSE. TRANSMISSION ACTS AS IF IT IS IN NEUTRAL. WHEN PLACED IN PARK, IF AUTO IS ON AN INCLINE OF ANY SORT, THE VEHICLE WILL AND HAS ROLLED FORWARD APPROXIMATELY 10 INCHES. THE CONCERN IS THAT IF THE CAR WILL NOT GO INTO REVERSE ON COMMAND, THE OCCUPANTS MAY NOT BE ABLE TO GET OUT OF THE WAY AN ONCOMING MASS. *TR

I HAVE AN 2009 AUDI A3 2.0T WITH AN AUTOMATIC TRANSMISSION. AFTER ABOUT 20-30 MINUTES OF DRIVING THE CARE THE TRANSMISSION STARTS EXHIBITING STRANGE BEHAVIOR. AFTER COMING TO A FULL STOP THE CAR LURCHES FORWARD AFTER LETTING THE FOOT OFF THE BRAKE. IT MAKES A CLUNKING SOUND AND THE GEAR INDICATOR GOES FROM THE GEAR NUMBER DISPLAN TO P-R-N-D INDICATOR AND THEN BACK TO THE GEAR NUMBER DISPLAY. IF YOU LEAVE YOUR FOOT OFF THE BRAKE, THE CAR WILL REPEATEDLY JERK FORWARD. IF YOU SLOWLY ACCELERATE THE CAR IS EXTREMELY JERKY AND NOT SMOOTH LIKE IT SHOULD BE. THIS MAKES FOR DANGEROUS PARKING IN A GARAGE OR WHERE THERE ARE OBSTACLES IN THE AREA. I AM AFRAID TO PARK IT. THE PROBLEM OCCURS EVERYTIME I DRIVE THE CARE FOR 20-30 MINUTES. *TR
