All good - fixed it Took the negative terminal off the battery for 5 mins to discharge all the power. Put it back on and it worked.

Sorry for the thread revival but I'm having the exact same issue... Car was jump started about an hour ago after the battery went flat. Odo/out temp display is completely blank as well as the speedo/tacho not moving at all. Fuel and temp gauge working normally. Is the 'dash module' you mentioned just the plugs behind the cluster itself or is it something else. It's after 9pm now and I'm not keen on pulling it apart! I guess it might have to be done..! Cheers
