Brake Fluid Bleeder Nipple + Order of Bleeding Questions

[bigtimemcalpine]

Anyone know the size of the brake bleeder screws for a 2010 A6? I'm hoping the answer is either 8mm or 10mm because I don't have a 9mm...In addition, can anyone confirm the order for bleeding when replacing the brake fluid?

Thanks!

I believe it's 11mm and the order Audi state for the A6 is.

Excellent thank you for responding - 11mm I can deal with. I made the mistake of using a 12-sided wrench to open up the bleed nipple last week and I stripped the nipple so I'm a bit more cautious at this point.
