X-5 Battery Drain - Page 2

Steve, thanks for the detailed directions, I've reviewed them several times and fully understand what I need to do. Well, tonight I decided to get started only to find out my older Fluke has two of the three fuses blown. I loaned it to a friend about 6 months ago and he must have used it to test the output of his arc welder (I can't wait to call him tomorrow, I just hope I calm down by then). Anyway, it's going to take me a while to find replacement fuses for the Fluke (or just buy a new one if he damaged it).

In the mean time, in desparation, I pulled out every frigging fuse in both boxes - and the shift lever light still won't go out after 16 mins (I had to leave in fuse #12). My DSC/ABS/Brake lights on the dash are on when I start up - could this be the problem why the car won't sleep? These lights were on before I started due to a dead battery that I replaced last week. Again, the problem I'm trying to troubleshoot is the shift lever light never goes out no matter how long I park the car. Once I get the Fluke repaired, I'll hook up and start pulling fuses!

Steve, OK, I have good news, the car is going to sleep after all. I followed your instructions and connected my Fluke 83 to the negative battery cable as you described. I was a bit surprised to see 4.65Amp battery draw with the rear hatch open (wow!). I shut the hatch and it dropped to 3.85A, waited for the interior lights to go out, then observed 848mA draw (still too high). I waited 16 minutes, and sure enough, just 27mA as she went to "sleep" - ZZZZ. Well under the 50mA guideline. Surprisingly, the orange led on the shifter was still proudly glowing orange even when sleeping.

My conclusion is: the older X5 shifter led's stay on when sleeping, my 2007's go out after the 16 minute sleep time. Thanks for all of your help Steve, I now know my X5 is fine and the new battery will last for years and I'm not slowly draining as I suspected. Now I'm off to the dealer for reprogamming to get the DSC, Antilock & Brake lights to go out (recalibrate Antilock, etc). Thanks again Steve from Morristown BMW!!! Attached are a couple of photos of the multimeter reading and the orange shift light still aglow!

Hi,
I'd need an update please...Did the orange shifter light stay on forever? And did your battery hold up or did it drain again like the others?
Thanks
(epic thread revivals are my thing...)

Wow, talk about an old thread! We still have our X5 after 15 years and yes, the orange shifter light stays on 24/7 even during sleep mode without any battery drain issues. It seems that some of the older X5's keep the shifter light on all the time for some reason without any problems.

Can't you just turn the wheel from left to right to make the DSC and ABS light to go out?
I did with mine yesterday after I replaced my battery and lights went out normally.

Nope, I tried that about 20 times and they're still on. Dealer says bring it in since the Antilock brake sensors need to be recalibrated after a battery change (another $100 bucks!).

Are you serious? This is brilliant German engineering? For what? BTW, what's FLUKE?
That's a lot of work to find the problem that should never have happened. BMtroubleU.

My X5 won't start after 3 days of not being used outside in 30F weather. Is this normal? Or is my battery on its way out? Last inspection I had done was about 2 months ago and the battery checked out ok.

**Added note, battery isn't completely dead. Remote still works, electricals still come on. Clicking sound only**

I have the battery drain problem. Second new battery and charging at 14volts, so its definitely a drain problem.

I am now testing the fuses. Fuse 75, Satnav/radio, 5 amps is drawing nearly 1 amp when i switch off the car, is this normal? Does it take time to "shut down"?

My park light goes out after 20 mins, but then lights up again - it does not seem to stay off permanently? Would the satnav/radio cause this?

When the park light is on i am getting 1.7 amps being drawn, and when it goes out is going down to less than .5 amp but not for long.

update - i went back out to the car and observed that the P light had gone out and the amps on fuse 75 were zero. Then just as previous the P light came back on and sure enough the amps on fuse 75 went back up to nearly 1 amp.

I am hoping that i have found the problem. I have left fuse 75 out, and have now got a meter on the battery terminal - just waiting for it to go back into sleep mode....

fingers crossed...
