Hi,
New to this forum

I need to replace the rear rotors/discs on my 2009 2.7 TDI A6 Quattro.

However, this all of a sudden turned into a PITA job when I discovered that the lower caliper carrier bolt is almost inaccessable, and that Audi has a set of special tools (one for each side of car) to get to these.

But then I found this guide:
https://www.audiworld.com/forums/a6-...2/?ref=esp-img

And it clearly states that the disc ca be removed without removing the carrier....Other DYIs says the carrier must be removed...

What is correct?

I did my rear brakes 2 months ago. I removed the carrier on the drivers side with some difficulty as I did not have the correct wrench to remove. I could not remove the passenger side. I was about to purchase the correct wrench but saw that post. It worked on the passenger side so I would assume it would work on drivers side. My car is a 2007 3.2 quattro

Carrier stays.

Thanks for your reply. Very interesting. What size is your rear discs?

Looking at this video:
Which obviously is a quattro car, the guy removes the carriers. I dont understand why he would do that if it was not necessary.
I read somewhere else that the carrier must be removed if rear brakes are PR code 1KD or 2ED.

Copy that.
Do you happen to know the PR code of your rear brakes?

No, not even sure what that is
