    Advice Please, We have a Hymer B 754 with fiat 2.8 jtd engine,on a recent tour the temperature gauge went to hot then normal then hot, all over the place,I Disconnected the main wire on the back of the dash board but still no luck. Cleaned sender unit wires,disconnected wires from sender, unit does not move, all wires refitted still the same.
    Could it be sender unit,your advice would be much appreciated.All this happens with the engine off.

    I agree, on my 'older' Hymer I had to re-wire the earth contacts on the pcb to get the temperature display workin properly.

    Too hot - remove shirt.

    Too cold - wear fleece.
