Carista engine code 25600/25603?

[Dwuk2000]

Yesterday I went on a long run and van was fine and today my van (2017 T6) won't start, it has a flashing coil light so read the codes in Carista and shows Manufacturer specific code of 25600 & 25603 and when reset they return.
Any ideas what these are as have searched and nothing, when starting I hear a noise from the rear so maybe fuel pump?
Going to test the battery voltage but at a loss at the moment

Does the starter motor turn over ?

Nope, when turning the key nothing except the sound from the rear and flashing coil.

I've got this today. Wifey broke down. It has the Diesel Preheat Orange coil symbol and Orange Exhaust symbol up. Strangely it says its empty of diesel and wifey assures me it wasn't. I believe her as she's not as stupid as I am.

Wife is adamant is was on 2 bars, so Im inclined to believe her. Plus you get audible alarms and warnings. She'dve noticed this. Still cant find what 25603 is. Anyone?

@Dwuk2000 did you find out what was up with that code?

Turned out to be a dodgy engine earth (drivers side of the engine) disconnected it all, cleaned up the connections and has been fine since.
