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.

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).

I own an audi a6, 2000. The car has been in the shop for over 18 months and 2 1/2 years for a re-accruing check engine light. For over 50,000 miles the car has been serviced by audi and audi only. Recently the car went out of warranty, however the check engine light is still not resolved and both flow and audi have washed there hands of it. In-addition, I just recently lost my 4 and 5 gear and only after I took the car to a different dealer we found that flow audi has been doing bad work on the car such as gluing parts back together (yes, gluing parts on a $55,000 car) and installing vacuum hoses up to the wrong parts. In-addition, they stripped out bolts and left them in place without fixing them, these bolts hold the engine together and in-place. (ask me about my timing belt issue, to long of a story to write on a web-page). The bottom line is audi and flow audi refuse to warranty the car any further, however the check engine light is still not fixed and its showing new codes. I have much more information... Also, ask me about my a4 (better story) flow and audi have cost me over 8,000.00 in the last two months and I have called everyone from the top of flow to the top of audi. There is no customer service and no response. My new mechanic is will to talk as well... There are no lemon laws and there is no one to help the buyer. It seems like no-one will talk to me since im not buying a new car. I really need help and advice.

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.

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.
