god damn this is terrible. I have the CPO for another 10k miles but my dealership employs a bunch of tight asses that bitch about just having DCI. I have the same codes 30BB, misfires on a bunch of cylinders, etc. 2007 build also. Does anyone know how to open up that little black clip with the fuses in it? Im driving myself crazy trying to get the cover off. I want to check those before i have it towed to the dealer.

DME code 30BB searched and found its possible bad diode
are you CPO? modded? did they cover everything? this better be covered. Its clearly a common problem with 07 builds I just want to smash my face into a wall

Thanks again for your quick response..def helped me get some rest before I got back to it this morning.
I'm having the same issue I have a Lci 2009 335xi and found that a 30 amp fuse blown Behind the glove box I replaced the fuse 3x it keeps blowing. I checked my main relay and it seems to be good. Any ideas why fuse keeps blowing ?

I know this is an older thread but it's worth posting what I found today to help anyone else who finds this via searching:

2007 328xi SULEV. F2 in the fuse carrier popped when my boss drove through a bit pothole.
Computer codes pointed me to the main relay which wasn't getting power and thus to fuse F2. A new fuse had the car running but, when I shifted it from drive back into reverse, the fuse popped again. 3rd fuse got the car back inside and then I started looking deeper at what was drawing so much amperage: the passenger side motor mount bracket had sheared the aluminum bolts and the motor had fallen about 30mm and was pinching the thermostat heater wiring between the water pump and the subframe. When I shifted from drive into reverse, the motor slammed down against the wiring and shorted it out again.

$10 in new bolts and 30minutes to remove the old mount for the room to unscrew the old broken bolts (they come easy out by hand or with a pick), then bolt it back up torquing to spec, wiring repair for the thermostat wiring, and just like that we have a perfectly running 94k N51 again.

Other things purported to be on F2: SAI pump, EVAP leak detection pump, DISA.

Ran some tests and found it was a blown fuse in the ECU box, replaced and car is running perfect.....just a heads up to all!
Hello and good day. I believe my DME in my 2011 335i xDrive (e90) may have just bricked. The car needed a jump, and now there is clicking everywhere from the passenger side fuse box, no crank at all, new battery, and it is charged for sure. I have read that you do "reprogramming" of new DME/CAS all that from the Bimmerfest forums. Can I ask you what I should do at this point and what i need to send to you to reprogram? I could buy a matching DME and CAS, would that solve my issue? Or does the cluster not communicate properly then? I'm sorry for the dumb questions, I am in a panic, and reaching for straws.

Thank you for any advice or direction.
