The Light Control Module can go out, it's about $380 from the dealer, and it's dealer only. Then you have to have it programmed. The vanos unit is another area that needs to be looked into. Do a search for Dr. Vanos and you'll see. Usually a rough idle 30 seconds after start up until it reaches above the blue temperature scale.
As Bill R. points out, the typical plastic radiator cracks, water pumps, thermostats built into plastic housings. Fan resistor plus the dreaded cyclone valve. You might not have as much of a problem with the cyclone valve or PCV valve because of the wamer weather. Typically, the valve will load up with condensate due to cold starts, then it freezes the valve in the closed position and the crankcase pressure has nowhere to go. Then it blows off the valve cover and dumps oil all over the exhaust manifold making for some more good cleaning fun. The PCV valve is located underneath the intake runners and is a bear to get to. BMW has redesigned this valve and the oil dipstick tube to flow better and not clog up.
The transmission has the famous lifetime fill that is good for a lifetime, who's lifetime is the question...I'll admit I haven't changed the fluid in the '01 525i and it's going on 163k miles. Same goes for the rear diff.
You might check into E39 tips and tricks for more information on other things such as wheel bearings and the like..
Good luck Bill B.
