Anyone Changed Brake Fluid & Bled With VCDS
Pretty much as the title implies. The car is coming up for its MOT in a few weeks time, and in the process of doing other stuff, I was thinking of replacing the brake fluid, as it was last changed about four years ago.
Has anyone done this themselves, and if so, how? There is an option within VCDS to bleed the brakes, but I've never used it, so not sure what it involves. Just wondering how much brake fluid I'll need to completely flush out the existing stuff.

I haven't done this myself. But as far as I can discover.
http://www.audipages.com/Tech_Articl...rakebleed.html seems to suggest 1 liter. According to my workshop manual, see attached file

Yeah a litre should do it.
VCDS is only needed to cycle the ESP pump if the system has been opened in that area or drained. For a straight fluid change it doesn't need to be done. The sequence is different for cars with ESP though: 1 - rear left 2 - front right 3 - rear right 4 - front left |

In terms of draining the reservoir, the length of the pipe doesn't matter - you've got the same volume of fluid going through it whether its an inch long or ten feet
The shortest first logic to bleed the system makes sense because any air from the master cylinder or ABS module will come out sooner. Elsawin does give the two specific procedures though - with and without ESP. Personally I think it makes no difference either way for a fluid change |

Great. I shall delve into that as well for instructions.

Hi Sean, there's something in the back of my mind regarding performing output tests on the D3's ABS module that it logs an error that can't be erased. I remember Snapdragon posting something about it.

Here is what I have on the ESP procedure.
MJ is correct of course, as always

Ignore my comment, just now realised it's your D2.

You might also invest in one of these. Makes it all so easy.
