Transit Connect/Dashboard not working

[C4th]

Hi,
New to the forum, hope I'm posting in the right section.

I have a Transit Connect 56 plate, 1.8.

I started the van up yesterday morning, fired up as usual, but dash was not working (Speedo, fuel gauge, revs, millage counter etc). Only indicator that remained on is the glow-plug light, and has remained on since. It's not flashing, just permanently on. Oil and handbrake light still show when key is put in ignition and turn off once started as usual.

Any help would be much appreciated,
Thanks.
