check the condition of the pump drive belt as the cold weather makes it more difficult to flex and if it is worn or loose it may be your problem

Low and high beam are in the same bulb

Is the high beam working or parking light ?

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/paul_0aa451e2c4466dbf

electrical short in the circuit or the headlight switch itself

Unfortunately these BMWs are prone to all manner of electrical problems.

Usually, the low beams and high beams are wired through separate relays (refer to your owners manual for fuse and relay info). It could be that there is a fault in the high beam relay (assuming that the globes in your headlights have been checked and are all OK).
I would recommend you get the car to a reputable auto electrician to check it for you.
Before doing that I would also talk to the nearest BMW dealership service department (a competent service rep) and tell him the problem. You can bet that there have been plenty of owners coming in with the same problem and if they are any good they should be able to tell you immediately what the likley issue is and what the fix is. If you get nothing call another dealer service dept rep.

remove the air filter housing ,simple .this programme has a spell check thingy working and its driving me nuts ,it cant identify plain english ,write colour and it squiggles it out but color is ok .

I had the transmission fluid checked. It was ok- Apparently a malfunction in the electrical system. The battery has been recharged and I drove it yesterday. It seems to be ok. I plan to replace the battery soon, since it has not been replaced since I purchased the car in 2004. I drive it so infrquently I think the battery simply died. It has been driven approximately 25 miles since December 2008. I plan to drive it on the highway this summer.

check the internet for a bmw e36 ETM ( electronic troubleshooting manual) everything you need is there.

your owner manual will list the bulb. It is expensive. tascafordparts.com for discount from Ford Dealer
