2007 AUDI A6 Power Trainautomatic Transmission Problems

PURCHASED USED AUDI 2007 A6 WITH 30K MILES AND MANUFACTURER WARRANTY. CAR STARTED JERKING AND STALLING ON ACCELERATION. TOOK TO DEALER 3 TIMES, EVERY TIME THEY SAY THEIR HANDS ARE TIED BY "AUDI CORPORATE" AND ALL THEY CAN DO IS CLEAN THE VALVE OR CHANGE THE FLUID. ONE DAY MY WIFE WAS TRYING TO ACCELERATE ONTO THE FREEWAY ON AN ONRAMP. THE CAR SUDDENLY STARTED JERKING WITH NO ACCELERATION, SHE NEARLY GOT SANDWICHED BETWEEN A SEMI-TRUCK AND A MINI VAN FULL OF CHILDREN. MULTIPLE DEALERSHIP STAFF AND TECHNICIANS INDICATED "A6 2007 TRANSMISSIONS ARE DEFECTIVE AND FREQUENTLY REQUIRE REPLACING, UNFORTUNATELY THE MANUFACTURER WILL REFUSE TO DO THIS UNTIL YOU COME BACK 4-5 TIMES WITH THE SAME PROBLEM." *TR

TO WHOM IT MAY CONCERN: WE ARE A GROUP OF OWNERS WHO BOUGHT THE AUDI ALLROAD 2.7 QUATTRO WITH THE TIPTRONIC TRANSMISSION. WE ARE WRITING TO REPORT A PROBLEM RELATED TO THE TIPTRONIC SYSTEM. WE HAVE NOTICED SIGNIFICANT HESITATION WHEN WE LAUNCH THE CAR FROM A STOP. WHEN THE CAR IS COMPLETELY STOPPED, AND THE DRIVER STEPS ON THE GAS PEDAL, A LAG OF 1-3 SECONDS IS OBSERVED. WITHIN THIS TIME RANGE, THE CAR JUST IDLES AS-IS WITHOUT MOVING FORWARD. THE SAME PROBLEM HAPPENS WHEN THE DRIVER ATTEMPTS TO ACCELERATE FROM 10-30. USING THE S MODE (IF EQUIPPED) DOESN'T COMPLETELY FIX THIS PROBLEM. WE CONSIDER THIS TO BE A SAFETY HAZARD FOR BOTH ALLROAD DRIVERS AND OTHER PEOPLE ON THE ROAD. A COMMON SCENARIO IS THAT WHEN A DRIVER ATTEMPTS TO MERGE ONTO A MAIN ROAD, AN INTERSECTION OR FREEWAY AND ANTICIPATES SMOOTH ACCELERATION, NOTHING HAPPENS AND THE CAR IS...

AUDI 3.2 ENGINE ON A 2007 AUDI A6 (AND SAME ENGINE ON A4 AND OTHER MODELS) HESITATES DURING ACCELERATION, ESPECIALLY FROM A STAND-STILL, SUCH AS A STOP SIGN. DEALER STATES THAT THE POWERTRAIN IS DESIGNED THIS WAY, AND THAT IT IS EITHER THE FSI ENGINE WHICH HAS A CARBON BUILDUP, OR THE CVT TRANSMISSION. EITHER WAY, THE HESITATION AND 2-3 SECOND DELAY IS PROBLEMATIC WHEN AT 4-WAY STOPS, OR WHEN MAKING A LEFT TURN IN FRONT OF ONCOMING TRAFFIC. THE DELAY CAN LEAD TO ACCIDENTS. ALSO, THERE IS A LOT OF INFO WEB ABOUT THE FSI ENGINES STALLING FROM THIS ISSUE (IE CARBON BUILDUP). *TR
