Hmm.... lemme go flag down mullet or witeshark, they'll be able to help you out with the fog light issue. I know in the older E36's you pulled the fog light out from the inside of the bumper to replace it. if memory serves me right, thats how the 740's work too. try that, and if that doesn't work.... i'll drive out there and yank it out for you
as for the crankshaft sensor, lemme look around a bit and i'll get back to you on that in the next ten minutes or so.
