So am fitting the new 312 calipers and brembo drilled discs soon and bit of info needed. Do I need to bleed entire system ? If so what's the order. Does the engine need to be running for abs pump. I have a vacuum brake bleeder for the compressor. 

Aslong as you keep the fluid pot topped up you only need to do the front brakes youve changed.

 

Engine does not need to be running for the ABS etc.

 

Just for the record, if you are bleeding the full system you start from the brake that's furthest away from the fluid pot.

Awesome thank you mate. I've done brakes before but you just never know if there are any little quirks or tricks with these little vw group things lol
