OK, theres some additional information on my problem.Last night, on switching on the ignition the erratic fan thing happened again, and then I heard some clicking from the engine compartment. I left the ignition ON, lifted the trunk and saw the Rear Shift Valve operating. I wasnt in reverse gear so this valve shouldnt be operating. My Essential Guide states this valve supplies a ground earth to the CCU.Is this making any sense?
