Hi you are going to have to get the brakes bleed through Volkswagen/seat diagnostic machine , as this will activate the ABS pump, just doing a normal conventional brake bleed will not bleed the ABS pump, the volkswagen machine will activate all the valves inside the ABS pump in turn to clear the air in the ABS pump, you will need a Volkwagen machine or VAGCOM diag machine to carry out this operation, i hope this helps Chris

i was told you only need to activate the pump when it has esp is this incorect as this cam from a vw dealer?

Hi sorry that is incorrect ESP = electronic stability program some cars have them and some dont , but any car with ABS will have brake fluid going through the ABS pump and with the amount of work you have had done , you will need to bleed the ABS pump, all ESP does is use the ABS pump to apply 25% braking to the wheels that are spinning faster than the others this in turn will stop the car from loosing control, this will not affect the bleeding of the brakes, you will have to bleed the ABS pump, i hope this helps Chris
