Cluster lights off main beam on

[jonnyswamp]

Noticed yesterday when driving that the dash is blank, no warning lights, clocks, indicator lights etc
Indicators work, car runs OK, doesn't go into limp mode (though I have only driven it for 10 mins at a time)
Main beam is on constant
Visually checked fuse no 42 and seems good (haven't tested yet)
Had an EIS issue a year or so back and had to get a reprogrammed key
It's going into the garage later (indie) to see what fault codes it throws up
Does this fault ring any bells with anyone ?

My guess is front SAM.
There is a cover over it on a clk. if that isn't fitted the scuttle drain can leak water all over it.
