Control unit ABS?

[eliteleon]

Hi there!
Im a proud owner of a Seat Leon 1.9tdi 2001
To pass the MOT, i need to change the fix an ABS light in instrumentpanel.
Following fault when connecting with VAG-com:
CAN-bus error.

Changing the ABS control module could fix the fault?
If so, where do i find the control unit for the ABS?

It could possibly fix it, but it needs to be diagnosed or at least a fault code number.

The control unit is built into the side of the ABS block which is located under and behind the airbox, loads of brake pipes go into it.

Looking at about 800quid for a new one.

Thanks for fast answer!
Did not get any number on the fault itself.
Changing the control unit, much labour?

Couple of hours work, plus fluid etc if it comes complete with the valve block.

If I change the complete unit......do i need to drain something? for example internal pressure?
