Hi Peter... Ive been re reading through your problem... it seems to me like youve gone over everything but something youre just missing...as of course we do.. my thoughts would be a faulty/intermittent immob. from what you describe? Hve you thought of removing / bypassing it? even if temp.... though I confess Im not sure how or even if you can do that on this model. But I'd be thinking along the immob lines... Mike
