2002 2.0hdi 90bhp no esp
Im having the braking fault and abs fault lights go off and the diagnostic says solenoid valve rear right and return pump as fault codes? is that the pump needing replacement or something else? Also using diagnostics the left rear speed sensor isnt sending speed even though its got a brand new sensor with 1-2mm gap and cleaned magnetic ring.

Sounds like pump is shot or corroded multiplug. A gap of two mm is too big for rear sensor gap anything more than 1mm is too big for reliable operation .

The pump is under the engine bay fusebox or somewhere over there? And the gap is the same on both sides and the magnetic ring looks ok on the left side.
Also the odometer reads 2x as less like when you go 1 km it reads it as 0.5km?

The magnetic ring might look OK but that does not mean it is OK. I had the same problem on the front and had to replace the bearing as the ring is part of it. It worked after! The ABS control unit is in the LH wheelarch under the wheel arch cover.
