U2108 ABS comms issue.
P1230 power supply relay issue.

Sounds like something gone tits up during work carried out. Has ECU been disconnected. Check for bent pins. Maybe wiring has been stressed.

Replacing the used clutch selector are you using the vehicles original gearbox control unit or the control unit as it needs the original unit for the car to stat
