Purchased from a hometown dealership
in Long Beach, CA, we now live in AL. 7 days now: low-beam, high-beam headlights & rear lights flicker on and off,
sometimes staying off. The dashboard lights and all other LED signals stay
operational without problems. A local BMW dealership
who performed a diagnostic test, fiddled with the battery cables; then said
it was fixed... Unfortunately it is not. Any ideas? Thanks

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.
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.
