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.
Consumer requesting assistance for a matter dealing with interamericana transport industries inc. After a new transmission was installed the consumer was still dissatisfied with the performance of the vehicle. Offensive odors have been emitting form the vehicle. These odors have made several members of the consumer's family ill. The door did not close properly.
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.
