DCV fault (assuming the wiring checks out OK) is either:

Fluid leak
Air in system
Faulty DCV (which is internal to the valve block, the external part is just a solenoid to activate the DCV)

Luckily I never had to remove any of the hydraulic pipes going to/from the valve block. So that's one less issue to worry about. Definitely isn't leaking (famous last words!)

I'm fairly certain the system is self bleeding as there really isn't much to it. You don't loss much from changing the filter and as the reservoir requires a top up, I'm guessing the air has got out.

None of the wires/connectors look damaged, but I will check it again.

So that takes me to a faulty DCV? Damm. Big Cry

Just find it strange that changing the solenoid's brings up two different faults?
