Reflashed Cobb, now 12v outlets dead???

jdub486 · 06-29-2012, 04:40 PM

I had to visit the dealer last week and thus uninstalled my Cobb tune from my 07 e92 335i. I flashed the tune again after getting the car back. Unfortunately I left the door cracked it drained the battery. The car still had power (radio, lights worked), but not enough to crank the engine. I jumped the car using the underhood prong but now both 12v outlets are completely dead. I tried resetting the ECU on the Cobb but that did nothing. Any ideas? Really don't want to go back to the dealer or indy shop.

They are dead when the car is off or on? Mine never work when the car is off, it's supposed to be like that.

Sounds like you have a blown fuse. Really cheap and easy fix. Check your owners manual for how to get to the fuses and which one to pull.

yeah probably a blown fuse.

It's an easy fix luckily

Also, if the battery is low, the electronics will turn off certain items to make sure there is still enough power available to run the starter motor, could be that? Maybe get the battery checked?

If not try a fuse, and remember that 12V outlets do not work unless key on accessory.

Fuse indeed. Took 5 mins to fix. Thanks!

Flashing the car drains the battery, and like you my car is also a 2007 so it might be getting time to replace the battery.
Any good deals out there?

Buy from dealer with bmwcca discount, then register yourself with coding cable.
