2000 Audi A6 Engine

2000 AUDI A6 4.2L V8 QUATTRO ENGINE COOLING SYSTEM FAILURE. THE PLASTIC COOLANT PIPE BETWEEN THE OIL COOLER HOUSING AND THE ENGINE BLOCK FAILS CAUSING POTENTIAL CATASTROPHIC COOLANT LOSS, OVERHEATED ENGINE AND POTENTIAL FIRE. *TR THE PLASTIC PIPE HARDENS/CRUMBLES WITH AGE, APPROXIMATELY 10 YEARS AND 135K MILES. I REPLACED THE PIPE...IT TAKES ABOUT 10 MANHOURS. THE REPLACEMENT AUDI PART IS MAYBE $20 BUT IT IS STILL PLASTIC. I REPLACED IT WITH A BILLET ALUMINUM PART WITH DOUBLE O-RINGS. DEALER WANTED $2900.00 TO REPAIR!! I UNDERSTAND THIS PART IS ON EVERY 4.2L V8 ON BOTH A6 AND A8 CARS FROM 1998 TO CURRENT 2010.

I HAVE HAD A LOT OF PROBLEMS WITH MY AUDI 2000 A6 2.7 TURBO EMISSIONS SYSTEM. I WAS TOLD I HAD A BAD CATALYTIC CONVERTER AT 90,000 AND THEY SAID IT WAS NOT UNDER WARRANTY. I LOOKED ON THE INTERNET AND FOUND HUNDREDS OF COMPLAINTS ABOUT THE AUDI'S CATALYTIC CONVERTERS. WHY DO THEY ONLY LAST 80,000 TO 90,000 MILES? THEN WE HAVE TO PAY $3,000.00 TO FIX IT TO PASS THE CALIFORNIA SMOG TESTS? THAT IS NOT FAIR. *TR

A STRANGE NOISE FROM THE ENGINE COMPARTMENT OF A 2000 A6 AUDI BEGAN SEVERAL MONTHS AGO. THE NOISE BECAME PROGRESSIVELY LOUDER. I THEN SUSPECTED A WATER PUMP MALFUNCTION WAS FORTHCOMING. THE VEHICLE WAS TAKEN TO AN AUDI DEALER FOR EVALUATION. THEY DETERMINED THAT THE WATER PUMP WAS DEFECTIVE, AND RECOMMENDED A REPLACEMENT. MOST PEOPLE WOULD NOT HAVE RECOGNIZED THIS NOISE AND AN ON ROAD ACCIDENT COULD HAVE TAKEN PLACE ON A FREEWAY WHEN THE ENGINE WOULD HAVE OVERHEATED AND SEIZED. SINCE THERE WAS ONLY 31500 MILES ON THE VEHICLE I AM CONCERNED THAT THIS TYPE OF PROBLEM OCCURRED AT ALL. EITHER THE PUMP SHAFT WAS BENT BY AN OVER TIGHTENED BELT OR THE PART WAS DEFECTIVE AT MANUFACTURING POINT. (THE BELT HAS NEVER BEEN ADJUSTED AFTER PURCHASE). *JB

THE CHECK ENGINE LIGHT CAME ON. THE CODE FOR THE LIGHT INDICATED A FAILED CATALYTIC CONVERTER HAD FAILED, THIS WAS AT 78K MILES THE DEALER SAID THAT IT MUST FAIL AGAIN BEFORE 80K MILE TO BE COVER UNDER WARRANTY. IT FAILED AGAIN AT 87K MILE AND NOW THE DEALER WON'T REPLACE IT UNDER WARRANTY. *NM

AT 61,000 MILES TURBO CHARGER SHAFT SHATTERED RESULTING IN CATASTROPHIC FAILURE, IMMEDIATE LOSS OF OIL THROUGHOUT ENGINE AND EXHAUST, LOSS OF DRIVABILITY AND SERIOUS FIRE POTENTIAL. *JB

BOTH CATALYTIC CONVERTERS FAILED AT 78,000 MILES. CALLED AND WROTE TO AUDI, WANTING THIS COVERED UNDER WARRANTY; WAS TOLD THREE DIFFERENT THINGS REGARDING COVERAGE (1. 'DON'T KNOW," 2. 7YEARS AND 70,000 MILES, 3. 8 YEARS AND 80,000 MILES.) WAS REPEATEDLY REBUFFED. COST $4600 TO FIX. AUDI 2000 A6. WROTE TO VICE PRESIDENT - AUDI OF AMERICA - AXEL MEESE - TWO MONTHS LATER RESPONSE SAID NO AGAIN AND QUOTED SOME OTHER WARRANTY (3 YEARS AND 50,000 MILES) IN ALL MY YEARS OF CAR OWNING, I HAVE NEVER HAD ONE CATALYTIC CONVERTER FAIL, LET ALONE TWO. I FEEL THAT THIS IS A DEFECTIVE CAR, AND THINK AUDI SHOULD COVER THE FAILURE OF THE CATALYTIC CONVERTERS.*AK

AT 65K MILES, MY BABY DAUGHTER AND I WERE DRIVING 70 MPH DOWN VAIL PASS ON I70 IN COLORADO WHEN THE ENGINE LIGHT STARTS TO FLASH. I THEN LOSE ALL POWER, BRAKES AND STEERING DUE TO A TOTAL ENGINE AND TURBO FAILURE. THIS PROBLEM WAS DISCOVERED TO BE CAUSED BY A WATER PUMP FAILURE, CAUSING THE TIMING BELT TO FAIL, IN TURN CAUSING THE ENGINE TO COMPLETELY SEIZE. AUDI REFUSED TO TAKE RESPONSIBILITY FOR ALL THE COSTS ASSOCIATED WITH REPLACING THE ENGINE AND DIDN'T LEND ANY CONCERN THAT THIS IS A SAFETY ISSUE. I HAVE RESEARCHED VARIOUS CONSUMER SITES AND HAVE FOUND SEVERAL COMMENTS DESCRIBING THIS EXACT PROBLEM. *CB

ENGINE CHECK LIGHT IS ON. DEALER HAS INSPECTED VEHICLE FIVE TIMES AND COULD NOT DUPLICATE OR CORRECT THE PROBLEM. *AK

THE VEHICLES CHECK ENGINE LIGHT ILLUMINATED. THE DEALER REFUSED TO SERVICE THE VEHICLE UNLESS THE CONSUMER PAID OUT OF POCKET, ALTHOUGH THE VEHICLE WAS TAKEN TO THE DEALER FOR SERVICE 3 DAYS PRIOR. THE CONSUMER PAID FOR THE CHECK ENGINE LIGHT SERVICE, IN ADDITION TO THE DEFECTIVE THERMOSTAT, WHICH CAUSED THE VEHICLE TO OVERHEAT ONE MONTH AFTER THE WARRANTY EXPIRED. SUBSEQUENTLY, THREE DAYS AFTER THAT SERVICE, THE CHECK ENGINE LIGHT ILLUMINATED AGAIN. *AK *SCC *NLM

HELLO, 2000 A6 HAS AN AUXILIARY FAN ON THE 2.8 ENGINE. MY AUDI WAS IN WARRANTY ON 10/17/02, AND IT WAS BROUGHT TO THE DEALER. THE DEALER WAS UNABLE TO DUPLICATE THE PROBLEM. THE PROBLEM IS THE FAN MAKES ALOT OF NOISE, AND THE FAN SMELLS LIKE A FIRE IS HAPPENING..NOW THE LOCAL DEALER, WAGNER AUDI IN BOYLOSTON, MA CHECKED THE CAR, AND WILL NOT COVER IT UNDER WARRANTY.. THIS SHOULD BE CHECKED OUT BEFORE SOMEONE IS HURT IN A FIRE FROM THIS AUDI A6 PROBLEM. THANKS, DON MELANSON. *NLM

CYLINDER HEADS (V-6, 2.7 LITER, 5-VALVE) ARE LEAKING OIL FROM THE ENDS IN AN AREA WHICH IS PLUGGED WITH A "BALL SEAL" PRESSED IN PLACE DURING MFG. OIL DRIPS ONTO EXHAUST CAUSING CAUSING MODERATE TO SEVERE SMELL OF BURNING OIL INSIDE AND AROUND VEHICLE. DEALER MECHANICS WERE ABLE TO LOCATE PROBLEM BY INSERTING SPECIAL DYE IN THE OIL AND CHECKING WITH A BLACKLIGHT, AND STATE HEADS NEED TO BE REPLACED. DEALER DENIES DEFECT AND SUGGESTS THIS AS A NORMAL WEAR ITEM, BUT THERE ARE NO MOVING PARTS. I AM WORRIED ABOUT COMPLETE FAILURE OF THE SEALS RESULTING IN OIL/OIL PRESSURE LOSS, EXTENSIVE ENGINE DAMAGE AND/OR FIRE. *NLM

THE CAR MAKES A WHINING NOISE ON COLD START. IT HAS BEEN IN FOR REPAIRS SINCE MARCH 2, 2002. ZAUMBACH OF MANHATTAN HAS REPLACED THE ENGINE, TURBOS AND WATER PUMPS DUE TO POSSIBLE LEAK. THEY CANNOT REPAIR THE CAR, THEY SAY THE NOISE IS STILL PRESENT. NO ONE KNOWS WHAT THE PROBLEM IS AND IT MAY BE DANGEROUS.*AK
