vcds bleeding abs

[cfcorp]

Hi folks,
I've got an 08 audi with a Bosch 8.0 abs module, i know this is a vw site but the module is fitted to vws,
How do i bleed it using vcds or what's the procedure? The problem is that i can't bleed one circuit of the brakes no matter what i do, even with a vacuum pump and a pressure pump for the reservoir, there might be air in the abs pump. There are no fault codes.
I've already changed the master cylinder with no luck, the original problems was a seized front calliper, now my brakes are dodgy.
The vcds procedure seems different to my b6 with an mk60 abs pump.
Anybody any ideas?
I've also posted this on the audi forforums uk
Thanks guys
