X5M battery dead after cleaning
 

It was sunny and warm on Sat so I decided to wash my X5M and vacuum it. I spent a few hours cleaning the car with one door open at a time and by the time I was done the battery was dead. I couldn't start the car and couldn't even open the trunk. Put it on a charger and battery had only 9% left. I had nothing on during clean up, just the door light. Imagine taking the car to a detail shop..may have to call a tow truck if you don't have a battery charger handy.

I also cleaned up my wife's 09 Accord at the same time and had the door light on too and the Accord didn't have any problem.

Did anyone experience this?

with the list of problems you could get with a M, be lucky its just that ! idk honestly..

And that's the sad truth................. ! :nervous:

Cheers,

Did you leave the key in ignition?

No I did not. Did not have anything turned on except for the door light that was on when the door was open.

The lights should've turned off after a view minutes to prevent this.........Phil

Had this same experience on my 2008 E70 4.8.....jumped it (took half an hour) took it to the dealer and they told me i left the door open too long without starting the car....after the third time i got a new AGM battery and problem was solved, at least for as long as i had the car.....hoped to hear it was resolved inthe E70's with the newer batteries as I'm trying to figure out what to get next.

That is a funny reponse from the dealer. I had my Accord's door open the same amount of time to do the same cleaning and its battery didn't die.

i clean my m all the time w the radio and doors open the whole while never had an issue

I've NEVER had an issue on any of my other vehicles...was a little disappointed, but "big brother" (aka the car) told the dealer this was it's problem along with the fact that I did not drive it enough (20miles per day) and they would never doubt it......whatever..eventually a new battery fixed it all..
