Q.1 Will any Rover 75 petrol / diesel ebay 2nd hand Rover 75 ECU ABS fit a diesel without traction control?

A. There is a 2 letter code stamped on the aluminium valve body of the ABS unit (don't confuse this with the pipe identification letters).
If your car doesn't have TC, you should not fit a ABS ECU from a vehicle with TC.

Q.2 Can you just swap the plastic front bit with the elctronics and solenoids in it without disconnecting the fluid pipes?

A. Yes you can albeit a bit fiddly.

Q.3 If you unscrew the plastic front bit does it leak brake fluid?

A. No

Q.4 Do you need T4 to open valves and bleed replacement abs?

A. You don't need to bleed the ABS unit if you are only swapping the ECU.

Q.5 Does ABS need T4 to code it to the car?

A. No, provided you go by the 2 letter code.

Any hints of DIY ABS replacement?

Make sure you have your radio code (unless you have hi-line satnav/tv or aftermarket).
Battery & battery tray out, disconnect harness multi-plug, un-mount ABS unit by removing the bolts from the top bracket & then pull up on the whole unit to release the bottom locating pin mounting.
Twist the whole unit around slightly to gain access to all the ECU mounting screws.
If I remember rightly, they are security Torx screws (they have a central pin sticking up so your Torx bit needs to be hollow in the centre).
