I stopped to pump some gas this morning. I turned the car off but didn't remove the key as I usually lower the rear pass. window so I can listen to my music while I stand by the pump. Anywho, I finished pumping, got back in the car, depressed the break and hit the Engine Start/Stop button. That's when it happened: everything turned off! Everything. The radio went off, the interior lights, the display, everything! I kept pressing the brake and start button and nothing happened. I even pressed the radio power button and it didn't turn on.

I removed the key, re-inserted it, and it started up normally. WTF? Electrical gremlins?

Not while pumping gas, but it has happened to me only once. i thought my battery had died... the remote key wouldnt even open the doors.

Happened to me before

The dealer didn't correctly tighten up battery

My car hasn't been in the shop since early June. I'm not saying that's not the problem, but it's weird that it happened now.

It seems like the normal process of things in a way.

Car is running
Push Start/Stop button turns off car, electronics still on
Press again, turns everything off

Seems normal to me.

depress brake, press start/stop, car should start (not turn everything off).

I suggest you go to your car and try it. Also, if it were normal operation, the radio would've turned on when I pressed the radio power button, but it didn't.

Really? I just went out to my car and tried it.

I turned the car on, then turned it off, and left the radio on. Opened the door, closed it, then opened it, closed it, depressed the brake, hit the start button and the car started up. Same sequence as before, only this time it started instead of turning everything off.

I suggest you go try it before posting.

You can also re-start the car 2-3 seconds after taking the key out. Its freaky but it works every time. Try it out.
(if AT, keep foot on the brake)

[hipnotic]

normal, mine does that when i sit in the car while listening to the radio with the engine off

[bbob]

hmm... is it becuz of the model year of the car... mine is 2009 e90 and i got the same results as couch:

Yes, but are you PRESSING THE BRAKE when you hit the button?

If you don't press the brake then it will turn everything off (that's normal). What's not normal is when you press the brake, everything goes off, and you can't even turn the radio on by pressing the radio power button.

I read something that you just hold start button down a couple seconds to start the car without it turning off the electronics.

everyone knows you cant start the car when your press the brake. like 80% of us said.. its normal. sometimes it happens, sometimes it doesn't. maybe you arent pushing the brake hard enough?

i suggest YOU go try before you post.

if you read the post, I already posted that I tried it again, as a test, after my OP. I've tried it several times since (on my drive to lunch, drive back from lunch, drive home, and drive to work this morning). Each time I depress the brake it starts the car not turn everything off.

I'm writing it off as a fluke.

If the car loses its power in that timeframe where there is limited power to your electronics, you will have to remove the key and reinsert it to turn things back on.


What you describe is normal - so you may have pumped more gas than usual/taken longer, or for some reason had a low power situation.

If the power does NOT shut off, then you should be able to start up just by touching the brake & pressing start.



To reproduce the problem - Start car. Shut off car, leave fob in place. Wait until your electronics/iDrive shut off. Try to start the car - it shouldn't. Start car by removing and replacing the key.

True!

Must be a fluke thing OP. I personally wouldn't worry about it.

[BenTrovato]

I read the original post.. and what happened makes sense.

When the car is on and you press start/stop once, the car goes off but electronics stay on if they key is inserted in the ignition slot. If you open the door, the very next time you press start/stop regardless if you press the brake or not, should power off all the electronics not start the car. Then you will have to remove, and re-insert the key.

If you do not open the door, the car should start up if you pressed start/stop. I'm not saying this is the truth, this is just my experience with the start/stop feature.

Sorry to resurrect this old post, but my '09 335ix E92 Steptronic CA managed to surprise me this weekend:

I moved the car out of the garage, shut it off in park with the pushbutton (keyfob in my pocket), foot off the brake pedal to make it so that just the electronics were powered up to run the radio without it 'timing out'.
I sat there for 5~10 minutes with only the 'middle' instrument-cluster lights showing, and when my spousal unit came out and sat down in the car (via opening and closing the RH door) I put my foot on the brake and pushed the 'start' button. The starter began turning the engine over furiously, the 'service engine soon!' warning came up on the cluster, and the engine failed to start.
I pushed the start button again, the starter stopped, and with my hoof still on the brake pushed the button again--and, again get just the starter cranking away madly and no start with the check-engine warning.
So-I took my foot off the pedal, pushed the button again to stop the starter, pushed it again to power off everything, then put my foot on brake again and pushed the button--VOILA! Engine starts fine, check-engine light goes out, all's well.

I tried it again immediately--all's fine, and it has been since.

I believe that my car is entirely too smart for my own good, and I'm not nearly as smart as IT is as it wants to make SURE that I fully intend to start the engine after listening to the radio for awhile and that I am not just messing aorund with it.

you have hooves?
