WHILE APPLYING THE BRAKE PEDAL VEHICLE HESITATED TO STOP COMPLETELY. VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION, AND MECHANIC DETERMINED THAT THE ROTORS NEEDED TO BE REPLACED, AND REPLACED THEM TWICE. HOWEVER, THE PROBLEM RECURRED. *AK......

SINCE I BOUGHT MY CAR IN 2001, I'VE HAD NUMEROUS PROBLEMS WITH THE BRAKES. WITHIN THE FIRST 4 MONTHS, MY ROTORS WARPED. THEY'VE WARPED TWICE SINCE THAT TIME. ALSO, EVERY 4 MONTHS OR SO, I HAVE TO TAKE MY CAR IN TO HAVE THE BRAKES RESURFACED. I'VE BEEN TOLD THAT I HAVE TO BRAKE AGGRESSIVELY RATHER THAN SLOW TO A STOP. SO, I'VE TRIED THAT. THE BREAKS STILL WARP AND NEED RESURFACING MORE OFTEN THAN THEY SHOULD. I'VE BEEN TOLD BY TWO MECHANICS AT TWO DIFFERENT DEALERSHIPS THAT THIS IS A KNOWN PROBLEM WITH SOME, BUT NOT ALL, AUDI A6 2.7 TURBOS AND 4.0'S (8 CYLINDER VERSION). THEY'VE SAID THAT THE TECHNICAL PEOPLE KNOW THERE'S A PROBLEM, BUT CORPORATE KEEPS DENYING IT. THE LAST MECHANIC SAID THERE ARE SOME THINGS THEY CAN DO TO TRY TO HELP THE PROBLEM, BUT THEY'RE NOT GUARANTEED TO WORK. NONE OF THE FIXES INCLUDED USING THICKER OR BETTER BRAKES, WHICH EVIDENTLY ARE AVAILABLE AT A HIGH COST! SOME OF THE TWEAKS THEY CAN DO INCLUDE PRECISION BALANCING OF THE TIRES AND MAKING THE SUSPENSION EVEN TIGHTER THAN IT ALREADY IS. *JB

AUDI 2001 A6 2.7T TIPTRONIC WHILE IN D TRANSMISSION MODE, CAR DOES NOT ACCELERATE PER ACCELERATOR INPUT AFTER USING THE BRAKES. THERE IS A DELAY OF ABOUT A COUPLE OF SECONDS BEFORE CAR ACCELERATES. THIS HAPPENS AFTER BRAKING FROM LOW SPEEDS FOLLOWED BY GENTLE ACCELERATION AND ALSO WHEN BRAKING FROM HIGHER SPEEDS FOLLOWED BY EITHER GENTLE OR AGGRESSIVE ACCELERATION. OFTEN THERE WILL BE A PRONOUNCED JERK WHEN THE CAR STARTS TO ACCELERATE AFTER THE DELAY. *LA SAFETY ISSUE TYPICAL SITUATION: WHEN CROSSING MEDIANS TO MERGE WITH TRAFFIC IN THE OPPOSITE DIRECTION, ONCOMING TRAFFIC HAVE TO BRAKE HEAVILY TO AVOID A COLLISION BECAUSE THE CAR IS UNABLE TO ACCELERATE SMARTLY AFTER BRAKING. THE SAME CROSSING IN PREVIOUSLY OWNED AUDI A4 1.8T AND AUDI A4 2.8 (BOTH WITHOUT FLY BY WIRE THROTTLE) COULD BE SAFELY NEGOTIATED WITHOUT ANY ACCELERATION DELAY. THIS SITUATION IS UNACCEPTABLE AND HIGHLY DANGEROUS IN NORMAL EVERYDAY DRIVING. REFERENCES FROM AUDIWORLD.COM FORUMS IT IS APPARENT THAT THERE ARE MANY OWNERS EXPERIENCING THIS PROBLEM. ALL HAVE THE AUDI TIPTRONIC TRANSMISSION AND FLY BY WIRE THROTTLE SYSTEM, NOT LIMITED TO THE 2.7T MODEL. HERE IS THE LINK TO THE LATEST MESSAGES HTTP://FORUMS.AUDIWORLD.COM/A6/MSGS/304185.PHTML ALSO, CONSUMER REPORTS HAVE NOTED THE DELAY IN ACCELERATION WHEN TESTING THIS CAR. HERE IS THE LINK. HTTP://WWW.CONSUMERREPORTS.ORG/MAIN/DETAILV2.JSP?CONTENT%3C%3ECNT_ID=302773&FOLDER%3C%3EFOLDER_ID=97851&ASSORTMENT%3C%3EAST_ID=333137&BMUID=1066370138539 SEVERAL OTHER REVIEWS IN THE U.S. AUTOMOBILE PRESS HAVE ALSO NOTED THE DELAY. REPAIR LOCAL AUDI DEALER IS UNABLE TO OFFER A SOLUTION SINCE THEIR TROUBLESHOOTING TECHNIQUES ONLY INDICATE A "NO FAULT FOUND" OR "UNABLE TO DUPLICATE" SITUATION (SEVERAL VISITS). ESCALATION TO AUDI HEADQUARTERS ELICITS STATEMENTS SUCH AS "WORKING AS PER DESIGN, "SAFETY FEATURE (PREVENT OVER REVVING DAMAGE TO ENGINE/TRANSMISSION)", AND "SYSTEM HAS TO PROCESS A LOT OF DATA". *LA

DURING INCLEMENT WEATHER DRIVER MUST PUMP THE BRAKE PEDAL TO STOP THE VEHICLE. ALSO, THE BRAKES GRAB IN THE REAR. DEALER REPLACED THE BRAKES FOUR TIMES, BUT PROBLEM STILL EXISTS. *AK

CAR BURNS OIL 1/2 QUART/1000 MI. ALMOST RUNS OUT BEFORE WARNING LIGHT COMES ON. AUDI SAYS THIS IS NORMAL- WE HAVE HAD TWO EMERGENCIES ON THE FREEWAY WHERE WE ALMOST RAN OUT OF OIL. ALSO, IT IS VERY HARD TO READ THE OIL DIP STICK- IT IS ARTFUL NOT USEFUL. ROTORS (ALL) FAILED AT 14K MILES AND HAD TO BE REPLACED. WE ARE ADVISED WE ARE NOT ALONE. AUDI CORP ARROGANT AND WILL NOT RESPOND. THROWS EVERYTHING BACK TO DEALER. DEALER FIXED ROTOR PROBLEM AT NO COST. TRIED TO CHARGE FOR OIL TEST REPAIR. BELIEVE THERE ARE DESIGN ISSUES IN BOTH INSTANCES. AUDI HAS LEARNED NOTHING FROM THEIR PAST PROBLEMS- THEY ARE THE MOST ARROGANT BUSINESS I HAVE EVER EXPERIENCED. *JB
