Excuse my lack of technical knowledge here...
I'd been told i needed to replace my ABS Pump Control Unit as if it's a thing, but the more I read about these it's actually several things? Am i correct in saying it's more likely that it's the Control Unit that's failed and not the ABS Pump? And in that case is it not possible to remove the (Electronic) Control Unit by itself for repair or replacement - just means there would be no ABS control? Or is it always better to repair or replace these two things as a unit?
BTW the above is all academic as I've now purchased a s/h ABS Pump (and?) Contol Unit and await delivery. Just interested...
ABS Pump Control Unit
Re: ABS Pump Control Unit
They are a single unit but can be persuaded to separate. I'd be interested to know what fails in them.

Re: ABS Pump Control Unit
yes me too as its either the unit failure or a wiring break, i have tried 2x used units and still cannot communicate with the abs brain via Vag Com,,, 
Re: ABS Pump Control Unit
that's not good news... Not expecting mine until next week, but will report back.
Re: ABS Pump Control Unit
The fault on mine was some of the very fine wires in the control unit had broken. Not repairable.

Re: ABS Pump Control Unit

at the moment awaiting some other input from a higher source , will keep you informed , apart from the the car is stunning , forgot how quick it is,

Re: ABS Pump Control Unit
right so mine is going back to the dealer for a date with the mother hub, so it can be connected to the all seeing dealer , and then [no doubt ] the fun shall begin , i feel i am heading towards a new abs module 
this will be how it feels no doubt,,
this will be how it feels no doubt,,Re: ABS Pump Control Unit
Good news , all coded at the local dealer and its sorted , seems that if buying a used brain it needs to be recoded to the recipient vehicle using the original abs brains code, which could not be retrieved as comms to the unit was part of the problem, so i will be taking a note of all the control units for any further reference.
Then once this was sorted the ac began working again, .
picking it up this afternoon with a new ticket ,
