I'll give it ago. Cheers bud. The dash all lights up as bright as normal the glow plugs do there thing. Are you sure it's battery terminals or similar. I should probably mention that I had driven 20 minute journey then parked for 30 mins. Got back in and click.You've got a bad connection somewhere. Start at the battery by taking off the two connections and clean to shiny metal and reassemble. If that doesn't do it follow each wire doing the same with each connection. If that doesn't work there's a strap between the chassis and the engine, take that off and clean the connections.
Odds on it's the battery connectors though.

Once again thanks for the advice everyone. One very wet back later it turned out to be the main earth strap. The heated seat was a god send to help dry me off on the way home.
