Paper clipped it for codes now I have no radio, dash or climate. Where to look?

Omega MV6 3.0 facelift estate.

Noticed a slight missfire at low revs so I read the codes and got a crank sensor fault code.  Car has also just failed MOT on emissions test - not sure if its all related.

As I pulled the clip out of the diagnosis socket I think it arc'd against something - not sure what, didn't think much of it at the time. 

Just come to drive the car and the dash light all work but all the gauges, climate unit, radio, display screen and hazard lights are not working.  Everything else works fine - seats, lights, locking etc

Checked fuses under steering  - all seem ok.  Checked fuses under bonnet - all seem ok.

I'm at a bit of a loss where to look now.  Any fuses or relays that I should be paying particular attention to?

Problem solved.

Dodgy fuse 12 under steering wheel.

I'd go back and check all the fuses again, take them out one at a time and visually ensure they are not blown...
