3 fuses were missing from the board below the gear lever! 

That'll be since new then 5 yrs ago!

Of course they queried the campervan electrics.

Of course they asked if I'd removed and not replaced.

None of the above!

So I'm guessing it's just a oddity should've caused issues off the production line but taking 5 yrs and 21k miles !!!!!
