Vag Com needed

just found this out myself, if you have air in the abs pump you need vagcom to sort it
did you bleed the master cyclinder on both nipples??
luckily i didnt need the vagcom when i done mine

put key to ignition and pump brake pedal till it goes rock hard, then with pressure on pedal start the car, if pedal goes down slightly then your servo is working fine

. . Probaly nieve of me but only did the callipers   did rear passenger, rear drivers, passenger side then drivers. didn't even think about the Master cylinder it self, is it easy/same as doing the callipers ?

i can pump the pedal hard . . ish i can still force it down a bit if i really force it and i do get kick back when i turn the ignition so not the servo then

no, not servo then, looks like your in the same boat as me right now, im gonna try bleeding some time but i have the usual habit of snapping the nipples

Well i had fun yest replaced 3 bleed nipples as there were foobard and then had fun with a sheared bolt and a odd drop link http://uk-mkivs.net/forums/t/379564.aspx

Going to get hold off Vag com and wire then bleed all again and master servo then prim ABS pump and see how it is after.

How had is it to do the servo and the vag the ABS ?
