[Biturbos4] High Mileage APB engine codes

[Michael Benno]

Just wondering what are some of the higher mileage 2.7t motors out there and generally how they are holding up. I have not really herd of too many 2.7t with higher miles than mine. I would be curious to know if there are and what indicators people are seeing with their motors. 

--- 

My 2000 A6 2.7t (6speed) has just over 85000 miles on it. I have owned for about 20k now and it has been chipped (MTM Stage 1) for about 5k. 

I would not say my APB has been well cared for by the PO. When I got it, it still had the original, and defective, TBB. Additionally many of the warranty recalls had not been done. Additionally there was significant amounts of oil gunk in the valve train, which leads me to believe it was subjected to factory change intervals. A few frequent oil changes every 2000 has really helped that out. 

Interestingly this Audi V6 seems to consume less oil than others that I had. I would say about 1/2 quart per 3000miles. My 01SAvant would go through at least a quart every 3k, but that car seemed to be getting better as it broke in. 

I would say in general the motor is running very well still (knock on cast iron), much like the way my 01S4Avant was when new. Turbo noise is louder when cold but goes away after about 5 -10 min. But nothing that would indicate failure. It is my assumption that the turbos are stock as there is no warranty repair history on these components. 

The valve cover and cam adjuster seals have been replaced based on visual inspection. I am approaching the timing belt repair soon and don't plan to change it until the specified interval because I have purchased supplemental insurance (covers the turbos too). 

So that is about it, I look forward to hearing from all you other high milers.
