we have a 2008 fiat ducato 2.3 diesel based motorhome. intermittent issue in that it wont tart as immobilizes itself. Dash shows padlock and ABS disconnected message. Sometimes says radiator fluid over temp (which it cant as hasn't run)! I think seems worse after rain, but not kept proper records. Getting fed up now as fiat commercial failing to find a fault as always seems to work when i get it booked into them! Any suggestions as I am thinking of just biting bullet and asking for new ecu and connecting wires? Can the immobiliser be bypassed as van is virtually unusable at resent. Cardiff based.
