No need for the frowny faces . . . we feel your pain.
I just changed my CPS a few months ago with a lot of help from the guys here (see http://www.bimmer.info/forum/showthread.php?t=14490).
If your husband doesn't mind doing work on the car he should be able to do it on his own. I had to remove my intake manifold but I have a '94 525i.
Find the toothed gear with your fingers when the engine is **not** hot. The sensor is probably less than 1 cm away reading those teeth. Follow the wire in the sensor and follow it to the plug. My wire meandered up the front of the engine, and disappeared under the intake manifold. The plug was under there too.
Please do not use this information to nag your husband: "Everybody online says it's so easy . . . so why can't you FIX IT ALREADY!"
