VW T6 Diff Lock Stuck on

[mmi]

no light on the dash cluster and no locked diff,

I would agree - no light - no diff-lock.

could this be the solenoid stuck or could it be a wiring problem

Basically no light on the dash indicates no vacuum at the diff-lock. Can be wiring, solenoid, or failing vacuum line.
Have you checked for fault codes?

No not yet, I need to get a fault code reader..
I’ll get one when I’m back home later in the month

I drove to work. Literally 5mins from home, but was having a delivery to my work and thus I took van. I walk to work, normally. As I turned into my work road, the beep alerted me to a fault, i looked at dash i had the 4wheels with the X on it light on dash. As I turned, what sounded like clicking could be heard and I could feel it through the wheel too.

I drove it back home whilst under that fault. Felt awful when turning. Parked up at home. Plugged in vcds and the statement is attached above.

I assumed it was the diff lock due to light on dash and sound. It may be other things. But whilst on fault, i could neither engage/disengage diff via the switch.

I have since cleared all faults. I've not driven it yet.
