Bosch 5.3 ABS modules

[jay8086]

Hi all,

Thanks to the info here on the various symtoms my 306 has, abs light on, diagnostic light on, speedo randomly drops out for could be seconds or til the cars stopped, it looks like the module in my abs is shot. Mines a Y reg phase 3 so i'm sure its the bosch 5.3 setup. My question is how compatible / interchangable are these modules. I presume i need to look out for another front and rear disc brake, 1.8 or 2l, 16v, phase 3, but is that all I need to worry about to avoid reprogramming the module?
Secondly if I find a car to get the part off is there anyone on here near Oxford that knows how to swap the module without taking the pump out of my car. (Aparently the module can be changed with the pump in situ).

Thanks for any help and advice.
