got a dispatch and had similar problems with glow light / instruments going mad and not starting.
turned out to be iffy wiring loom plug in connector on ecu and a possible broken wire in the loom.
got a citroen auto electrician to sort it - took him 2 hrs na d £120
now starts first time every time.
poss call up local citroen breakers and ask if they know of citroen auto electrician, thats what i done.
good luck
