Took 16 odd hours on the BMW computer at the $tealers to program my new LKM.
Before going that route I would go to Advanced Auto or the like and have them check the battery and charging system. Most do it for free and sell a very good replacement battery if needed.

I have a 2001 x5 3.0. I have been have a strange electrical problem that comes and goes. When the problems happens, I lose the Air condition, the air blows, but not cold. The radio goes out completely, no power or clock at all. The reverse lights and the heated seats don't work. The turn signals work on the outside, but don't flash or click on the dash. If you open a door, the indicator on the dash doesn't work. Also, the rain sensor wipers won't work, the wipers just work in normal mode. Also, I lose the ability to use the keyless entry and alarm. I have to insert the key to lock and unlock the vehicle.

The coming and going usually happen when the vehicle is parked and turned off. I will start it up and sometimes it has all features working, other times, nothing will work. Speaking with the dealer was useless. They basically wanted a blank check to troubleshot the issues. They told me that there must be a short in the dash and it needs to come out completely for them to search for a problem. At $90/hour, I don't need a dealer abusing me like they have done in the past.

Sometime the issue will be for days at a time, then start working for days. But lately, it has been mostly not working.

Thanks in advance, Dave

I connected the battery back up and within a few hours, the vehicle was working completely fine again. I have not had any problems since then, about 4-5 months ago. I guess that originally I just didn't leave the battery disconnected long enough. Good luck!

Thanks again,
Colin.
