    I'm replacing the brake servo on my 1998 a6 tdi and i've had to remove the master cylinder, reservior and the piping to the ABS unit, what i need to know is if there is any way i can bleed just this part of the system when i put it back together rather than the whole lot all the way to each caliper.

    As you have opened the start of the system you should bleed through the whole system which should require VAG com in order to put the ABS module into bleed mode which pumps fluid past the pump. then its just normal bleeding. You dont want to airlock the abs system as this will cause havock with the pump and stopping ability. If you find away round this then please post.

    On the plus side this means you will have replaced your brake fluid from start to finish

    Good luck

    Yeah, it's been sent to a local garage to have the system bled on one of those machines, too much air in the system to be bled using the master cylinder.
