My A6 has 82k miles. I am confused if it needs an ATF change or not. The dealer refuses to change the ATF. My Audi wrench recommends 80k miles.

Is there a consensus on this?

Does anyone sell ATF change kits?

The tranny's manufacturer calls for fluid changes every 50-80K miles depending on driving conditions. Let me tell you I noticed a big improvement in the tranny's performance after I had the ATF changed at 35K miles.

Attached is a link to a service guide put out by ZF the manufacturer of the transmission in our Audis. The link discusses that the transmission is designed to be maintenance free. However, it also says that the fluid should be changed every 8 years or between 80,000 kilometers (50k miles)and 120,000 kilometers (75k miles) depending on driving style. Accordingly, Audi's claim of "lifetime" is based on a lifetime of 8 years and 75,000 miles. Personally I inited on keeping the car for longer than 75,000 miles.

this subject has a very fine line because many people are scared to alter the OEM fluid, especially since audi claims it is lifetime. Without doubt, the transmission will function better after the change, but i have heard of many instances(on other models) of transmission failing shortly after ATF change....so go figure

Is there anyone with >100-200k miles on the original ATF?

on my C4 A6, I changed fluid every 80K and it lasted till the end with no issues.
I also would change diff fluids while on it.

At 109K on my '05 A6 4.2 with original ATF. No issues. I will chat with my independent Audi shop about this issue this week.
