Hi, ,Carried out your instructions, but still no joy. The immobiliser is still in place. The car doors lock perfectly but the red flashing light does not come on. On unlocking, the green light comes on, the doors unlock, but the engine still does not fire. There is no problem with the battery, the engine cranks but the immobiliser prohibits ignition. Is there a way of disconnecting the immobiliser so the engine can be started to drive it to a Mercedes garage?
