I have a broken fog light and a replacement for it. However I cannot see how to remove the old fog light unit.

Also can someone tell me where the crankshaft sensor unit is located. I need to replace that also. All help is appreciated.

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.

Thank you for a quick reply. Can you clarify "from the inside of the bumper " ? I'll look at it tonight. Thanks.

Well, on the e36's, there is a hole on the bumper on the side of the foglight closest to the middle of the car (inside the brake duct). If you stick a screwdriver in there, you can unpop the part of the bracket holding the foglight in the bracket. This lets you slide only the foglight out.

Crank position sensor is just about straight down following the oil dipstick tube. I believe that the wire passes behind the tube.

One cap screw holding it in.

Spacing between the sensor and the flywheel is semi critical. If there is a spacer reuse it, if not don't worry about it unless it doesn't run after the new sensor is installed. I believe it is supposed to be 1 mm between the sensor and the teeth on the damper.

I've replaced fogs on my dads 99 740i, you just simply pops the unit out from the side carefully with a flat screwdriver and it pulls out, but do it carefully.

there is a hole right next to the fog light on the lower section on the inside towards the grill.

use a thin long flat head screw driver, just push, the fog will literally pop out.

Look at those two holes, use the top one.

If you need more details, go to e38.org. I believe I saw procedure w/photos there.

I need to replace one, too. Where are you getting yours and how much?

yes, e38.org - good writeup / pics etc.
