Hey guys, I should be picking up a 2000 A6 4.2 this weekend. It has 106k on the clock and the timing belt will be done first, as well as all the other stuff in there. Is there anything particular I should look to replace in the motor department to ensure another 100k of fun =]

Thanks
Brian

Yay...Picking up my 4.2 tonight. Now it needs to hurry up and snow =]

Many have failed on the A6 4.2 from that period.

Don't ask me how I know :(

I have a 2000 A6 4.2 with 68K. The transmission shifts fine but I am unaware of any prior maintence as I recently bought the car. What if anything should I have done now and how much will it cost? Also must it go to the dealer?

Thanks much

Audi says the transmission fluid is "lifetime," meaning it should never be changed. Having my transmission replaced after failure at 60000 miles, I totally disagree. So did the transmission shop I took it to. My opinion, and several others on this board, recommend changing the fluid about every 30000 miles. If you do a search on Audiworld you can probably find pictures of the fluid one user saved from his transmission after an oil change at 30000 miles. It was extremely contaminated.

Other people however, suggest that changing the fluid ever, will lead to failure. Again, I disagree with this, but do a AW search and see what you think.

I bought my 01 one year ago with 70,000 miles. Within 6 months the thermostat suddenly (and without warning) stuck closed, causing the engine to overheat. Of course its behind the timing belt so I had "everything" done by my favorite indie for $1400 (aftermarket thermostat: I figure if the official Audi thermo's stick you'd be better off with another brand!) The transmission works PERFECTLY, so I did the fluid and filter change and it STILL works perfectly. I recoded it to 0032 (it's a legitimate Audi option and transforms the operation of the trans). A few months later it developed the predictable coolant leak at the oil cooler on the right side (oil filter/cooler) of the lower engine block. It's a $3.00 piece of plastic tubing that requires removal of the bumper to get to ($500-). The rear window shade has recently stopped retracting competely. Having experienced all that, I have to say that those are THE weaknesses of the 4.2, and that this car is the most interesting, enjoyable and all-around awesome car I have ever owned (30+ cars and counting). Just go ahead and do the thermostat and water pump while you are paying for the timing belt AND, LISTEN TO ME HERE!!!While the front bumper is in service position, REPLACE THE PLASTIC COOLANT TUBE/O-rings ON RIGHT SIDE OF THE BLOCK AND YOU'LL BE GOOD FOR THE NEXT 60,000 MILES. Do the trans fluid any other time as a totally separate project, and don't ever look back!! Any questions?
