Anyone have this happen? When I sit with the car off and key in position 1 for less than 5 minutes just listening to the radio, the low battery signal comes on. I don't want to risk draining the battery completely so I start the car. Could this be some type of sensor malfunction or possibly the battery isn't holding a good charge? Thanks

I have this too - first time it happened as dealer was doing a CIP upgrade and battery just died! they changed the battery and blamed it on defective battery - told me its fixed now. Got the same message after a week- decided not to worry about it anymore - justa glitch in software. I will mention it next time I'm at the dealers, but don't think they will fix it anyway!

Remember while the radio on the L7 amp consumes a lot of power (400W) from your battery. This is quite common for cars with L7 and Nav.
Do you guys sit in your E60's in the garage and listen hard rock
The E60 is so full of amp/W using electrical devices that without
driving the car the charger doesn't have the time to fill the battery.
For those who only drive some few miles at the time a battery charger
could be handy.
If the battery goes too low it will confuse the whole electrical system.
A E60 is not like the good old times Chevy where you could jumpstart
it whithout any problems.
Try to jumpstart your computer and cellphone...

My battery was doing the same thing for the past couple months. But since last week, everytime I go to start my car the battery has been completely drained. Even after sitting for only 2-3 hours. I dropped it off at the dealer last night and they're working on it right now. I don't have the L7 sound system, but I did do an aftermarket system. The dealer called me and told me that they thought it might be the stereo I put in, but I installed the stereo almost a year ago and I just now started having the problems after my CIP upgrade (20.02). Either way, they disconnected the stereo and ran another test and there is still a draw coming from somewhere else, so I don't really know what's going on, but I would say there's something wrong with the CIP version I have. Not to mention, the power draw due to my stereo would only account for the battery being drained when I have either the ignition on, or the car started, not when it's just sitting there overnight. I have an adapter that will only turn on my amps and power the whole system when it recieves an audio signal from the headunit, so if the car is off, there's no audio signal and there should be no power draw. I'll let you know what they come up with when I get the car back, no idea when that will be though.

Hahahha Ya you jump start a E60 or use your E60 to jump someone else... be prepared for a trip to the dealer so they can repace the iDrive and a bunch of computers... just ask around here... someones tried it here who jump started their other car and ended up blowing up the iDrive on their E60. I'm not saying it'll happen everytime but avoid it. If the batter is flat tow it into the dealer. Refuse a jump start from the tow truck. Or if your friend has a dead batter... call AAA for them.

E60 has voltage regulator, so it should be OK to jump start. I jump started my brother Ford Ranger pickup truck brazillion (remember the brazillion story in the lounge?) times
You're not right. If you have new headunit, it'll draw current from battery to keep it's memory alive.
there's no audio signal and there should be no power draw
