What transmission fluid to buy for 2005 Audi A6
I want to change the transmission fluid for a 2005 Audi A6, but am not sure which oil is best for the car. I will be glad if anyone would advise me on what will work best for the car.
Thanks in advance!

ZF Lifeguard 6 S671 ATF 20612A04 ZB11Z2

I replaced it at around 100K miles. probably will do again at 2OOK.
I also highly recomend to replace the steering fluid. It is very easy to replace.

I have used amsoil on 3 different A6's. I use Amsoil for the trans, diffs and transfer case. No problems after a lot of miles. You can check their site for the correct fluids and capacities.

I did the research and this is the matching OEM:

I have another question.
I bought the 2005 Audi A6 from the auction with a few ding to the body, which I felt I could fix. But the transmission is also making some squeaking noise, light vibrations, or shudders when changing gears, especially between gear 1 and 2, and gear 1 to rest. I ordered one of the ATF recommended by a member of this great forum, so I could change the fluid, hoping that would resolve the problem. However, I just realized there is a possibility the previous owner might have completed a technical service bulletin (TSB) issued on the car by Audi requiring owners to install a TCU software along with the new updated ATF. If the previous owner has done that, then the fluid I bought is no longer recommended for use.
My question are:
1. I don't want to go to the an Audi dealer shop to know if these changes has been effected on the car. Please, are there ways I can find out what TSB has been effected on my car before it got to me?
2. Even if the updates has been done, is it okay if I still go ahead and do a change of the trans fluid with the first version of AFT?
Thank you for your responses in advance.

if you have VAG-COM tool, you can read the info for the Transmission. I think someone explained to me what all the details in the info mean when I was changing the oil. I can compare your readings to mine and if they are the same, you need the same oil as I did.

Thankfully, I posted my transmission vcds info & was advised that my '06 C6 3.2 had the tsb update & required LG6+.
ecs tuning is the only supplier that I've found for that fluid also. Equivalents are out there, but that's my only source for the original "blue" fluid.

There's a great write-up on how to do this and you can determine what color you need as well:

Your choices are ZF 6, 6+, or 8. The best way to check is to take a sample of the fluid and then determine what color it is an match it to what you need.
