2001 Audi A6 Engine Problems

I HAVE A 2001 AUDI A6 QUATTRO 2.8L WITH P1411 AND P1423 DTC CODES. I AM HEARING IT IS A VACUUM HOSE OR COMBI VALUE PROBLEMS FROM WHAT I AM READING, COMMON TO THIS MODEL, BUT I HAVE HAD SEVERAL MECHANICS LOOK AT IT AND NOT WANT TO TACKLE IT. IN A RECENT FORUM I WAS TOLD MANY OF THE ITEMS I HAVE LISTED WERE RECALL ITEMS-INCLUDING VACUUM HOSES. YES, MANY WERE, THERE WAS EVEN A LAW SUIT WITH AUDI, THAT AUDI DENIED MY CLAIM AND PAID SEVERAL ON. I APPEALED AND THEY DID NOT RESPOND AND DID NOT DEFINE WHY THEY REFUSED TO COVER IT. AUDI STILL HAS YET TO COVER THE VEHICLE IN THE PROFESSIONAL MANNER I EXPECTED. MY LIFE BURDENS ARE ENOUGH, I DO NOT NEED A CAR MANUFACTURER OR DEALER TO YANK ME AROUND, THE VEHICLE NOW HAS 205,000 MILES, BECAUSE I PAID OUTRAGEOUS CAR REPAIRS ON IT. I FEEL AUDI IS A GOOD CAR, BUT FIXING THINGS ON IT THAT SHOULD BE COVERED UNDER RECALLS AND SERVICE WARRANTIES IS NOT HAPPENING. DO I REALLY HAVE TO SUE TO GET RESULTS, THIS IS RIDICULOUS! I HAVE EXPERIENCED CHECK ENGINE LIGHT, FAILED EMISSIONS TESTING, HEADLIGHT PROBLEMS, ISSUES WITH WATER IN LENSES AND MIRRORS, TURN SIGNAL ISSUES, I HAVE HAD PROBLEMS WITH MY FUEL LINE, REPLACED TIE RODS, AND ABS BRAKE LIGHT SIGNALS AFTER BRAKE REPAIR. I AM HOPING NHTSA CAN SHED SOME LIGHT AND ASSIST ME WITH RECTIFYING MY CAR SITUATION POSSIBLY. I HAVE BEEN DEALING WITH THESE ISSUES FOR MANY YEARS NOW AND I AM HOPEFUL TO RECEIVE SOME RELIEF. *TR

DRIVING WESTBOUND ON I20 FROM COLUMBIA, SC TO ST ROBERT/FORT LEONARD WOOD, MO WHEN ENGINE SUDDENLY LOST POWER. LIMPED ABOUT 3/4 MI TO NEXT EXIT AND CALLED FOR A TOW TRUCK. TRANSPORTED VEHICLE BACK TO NEAREST AUDI DEALER (45 MI EAST) IN COLUMBIA, SC. AUDI OF COLUMBIA DID DIAGNOSTIC AND AFTER $2527.00 DETERMINED THAT THE EXHAUST CAMSHAFT ON BANK 1 BROKE IN THE CENTER. THE SERVICE DEPARTMENT MANAGER STATED HE HAS NEVER SEEN OR HEARD OF THAT HAPPENING IN ALL HIS YEARS WITH AUDI. I BELIEVE THAT THIS IS A MATERIAL DEFECT AND I SHOULD NOT BE CHARGED FOR THE REPLACEMENT OF THE ENGINE (SERVICE MANAGERS RECOMMENDATION). *TR

HUGE OIL LEAK ON MY 2001 AUDI A6 4.2 CAUSED BY THE PCV VALVE FREEZING CLOSED. THIS HAS HAPPENED TO MY CAR 3 TIMES IN THE LAST 2 YEARS. THIS ONLY HAPPENS DURING EXTREME COLD WEATHER, COLDER THAT -10 DEG F. NO INDICATION OF THE FREEZE PROBLEM UNTIL THE CAR SLOWS TO BELOW HIGHWAY SPEEDS AND YOU CAN SMELL THE OIL BURNING. THE PCV VALVE FREEZES CLOSED WHICH ALLOWS PRESSURE TO BUILD IN THE CRANKCASE OF THE ENGINE CAUSING OVERPRESSURE AND OIL TO BE FORCED OUT OF THE VALVE COVER GASKETS, IGNITION COIL SEALS, CAM SEALS AND CRANK SEALS. SO MUCH OIL LEAKS OUT THAT IT COVERED THE ENTIRE ENGINE COMPARTMENT, THE FRONT SUSPENSION INCLUDING THE FRONT BRAKES, DOWN THE SIDES OF THE CAR, COVERS THE ENTIRE UNDERSIDE OF THE CAR INCLUDING THE ENTIRE EXHAUST SYSTEM. VERY SERIOUS FIRE DANGER AND POSSIBILITY OF NOT BEING ABLE TO STOP THE VEHICLE BECAUSE OF OIL ON THE BRAKES. MY CAR DID NOT START ON FIRE AND I WAS ABLE TO STOP THE VEHICLE. I HAVE CONTACTED AUDI OF AMERICA AND MY LOCAL AUDI DEALERSHIP AND THE DEALERSHIP ACKNOWLEDGED THE FREEZING PROBLEM AND RECOMMENDED THE INSTALLATION OF A REDESIGNED PCV VALVE. MY CAR IS ALREADY EQUIPPED WITH THE REDESIGNED VALVE, SO NO REPAIR WAS APPLIED. AUDI BLAMES THIS PROBLEM ON DRIVING HABITS OF THE OWNER ALLOWING THE CAR TO IDLE IN EXTREME COLD. I HAVE PICTURES OF MY PCV VALVE WITH ICE INSIDE OF IT AND HAVE CONTACT INFO ON OTHER PEOPLE THAT HAVE SEEN THE SAME PROBLEM, ONE RESULTING IN A FIRE. THE DEALERSHIP LOCATION IS FARGO, NORTH DAKOTA NAME IS VALLEY IMPORTS, TALKED TO THE SERVICE MANAGER. *TR

THE FAILURE OCCURS IN COLD WEATHER CONDITIONS. THE CONTACT IS IN THE PROCESS OF TAKING THE VEHICLE TO THE DEALER FOR REPAIR. THE FAILURE AND CURRENT MILEAGES WERE 65,000.

2001 AUDI A6 WITH ALL ROUTINE MAINTENANCE HAD CHECK ENGINE LIGHT ON AND WAS TOLD IT WAS NOTHING TO WORRY ABOUT. A FEW WEEKS LATER THE ENGINE BASICALLY MELTED WITH OUT ANY WARNING. DEALER SAYS THE RADIATOR WAS FINE AND THE WAS NO OIL LEAK. ALL WIRES ARE MELTED ONTO THE ENGINE AND THE ENGINE IS RUINED. SUSPECT ELECTRICAL PROBLEM. ONLY 2 YEARS OLD BUT OFF WARRANTY. DEALER OFFERS NOTHING AND AUDI OFFERS 4000 TOWARDS A NEW AUDI PURCHASE. A NET 37000 DOLLAR LOSS IN 2 YRS FOR ME. I WAS TOLD WHEN I PURCHASED THE CAR, IT WOULD EASILY GET 90000 TO 15000 MILES BY EVERY DEALER. THEY ARE COVERING UP AN ELECTRICAL DEFECT OR SEVERLY MISREPRESENTING THEIR PRODUCT. *AK

I HAVE A 2001 AUDI A6 2.7T AND IT HAS ALMOST CAUSED ME TO GET INTO SEVERE ACCIDENTS WHERE I WOULD HAVE BEEN SERIOUSLY INJURED OR KILLED IN A SIDE IMPACT COLLISION. THE CULPRIT IS THIS: IF YOU DEPRESS THE BRAKE (AS IF YOU WERE STOPPING OR COMING TO A COMPLETE STOP) AND TRY TO REACCELERATE, THERE IS LITTLE TO NO ACCELERATION. THIS "HESITATION" HAS ALMOST GOT ME KILLED SEVERAL TIMES. THERE ARE HUNDREDS OF OTHER AUDI A6 CONSUMERS REGARDLESS OF MODEL ENGINE (2.8, 2.7T, 3.0 AND 4.2) THAT HAVE EXPERIENCED THIS PROBLEM. THUS, IT IS UNACCEPTABLE FOR AUDI USA TO SAY THIS IS "NORMAL" AND "INHERENT IN THE OPERATION OF TURBOCHARGERS" AS THIS IS WHAT THEY HAVE TOLD ME BEFORE WHILE THE CAR WAS BEING SERVICED. ALTHOUGH I DO UNDERSTAND THAT TURBOCHARGERS CREATE WHAT IS DEEMED AS "TURBO LAG" ON ACCELERATION, I EXPERIENCE MAJOR DELAYS IN ANY ACCELERATION IMMEDIATELY AFTER I HAVE DEPRESSED THE BRAKE (AT ANY SPEED) AND THEN TRY TO REACCELERATE. THIS IS A SERIOUS ISSUE AND NEEDS TO BE FIXED OR REMEDIED IMMEDIATELY. PLEASE SEE THE POSTING AT AUDIWORLD (THE LARGEST ONLINE FORUM FOR AUDI OWNERS).

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

THIS IS THE SECOND A6-4.2 THAT HAS THIS PROBLEM. THE CAR DUMPS ALL POWER FROM SLOW SPEEDS. IMAGINE PULLING OUT INTO TRAFFIC FROM A SIDE STREET OR ONRAMP AND TURNING THE IGNITION OFF. AUDI REPLACED MY FIRST A6 BECAUSE OF THIS PROBLEM AND NOW ACCORDING TO THE SERVICE MANAGERS AT THE DEALERSHIP HAS NUMEROUS OTHER 2000 AND 2001 A6'S AND A8'S WITH THE 4.2 ENGINE THAT ARE EXPERIENCING THIS PROBLEM. IT 'S ONLY A MATTER OF TIME BEFORE THERE IS GOING TO BE A HORRENDOUS T-BONE OR REAR-END CRASH WITH THESE CARS. ACCORDING TO THE DEALERSHIP, AUDI KNEW THAT THESE CARS HAVE THIS PROBLEM WHEN THEY TOOK BACK MY ORIGINAL A6 AND SOLD ME THE SECOND ONE. THE AUDI ZONE MGR ASKED THE SERVICE REP WHY THE HECK THEY SOLD ME ANOTHER ONE. THIS IS A RELATIVELY EXPENSIVE AND RARE CAR BUT THEY CONTINUED TO SELL THEM AFTER KNOWING FULL WELL THAT THERE IS A SERIOUS FLAW IN THE ECM AND THROTTLE COMBO THAT MORE THAN LIKELY WILL CAUSE SERIOUS ACCIDENTS. AFTER 5 WEEKS OF PHONE CALLS TO AUDI CUST RELATIONS IN MICHIGAN I HAVE GIVEN UP AND WILL HAVE TO GET LEGAL HELP. I HAVE IMPLORED THEM TO TAKE THE CAR BACK DUE TO THE SAFETY ISSUES AND CUST RELATIONS HAS PLAYED RUN-AROUND WITHOUT GIVING ME ANY ANSWERS UP TO THIS POINT TODAY. THE MOST ASTOUNDING POINT TO THIS IS THAT I HAVE PURCHASE 6 OR 7 AUDI'S OVER THE YEARS AND 4 NEW VW'S FOR MY KIDS IN THE PAST 6 YEARS AND THEY ABSOLUTELY DON'T CARE IF I GET HURT OR KILLED IN THIS CAR! THIS MODEL CAR WITH THIS ENGINE WILL KILL SOMEONE IF THEY DON'T DO A RECALL TO FIX THIS PROBLEM ASAP. I GUESS THEY ARE RELYING ON THE AIRBAGS SAVING THEIR CUSTOMERS
