OK, I just finished installing my Vargas Stage 2+ turbos. After firing the car up, I am now getting a P30BB (injector, power level 2) code. After clearing the code it comes back immediately after I turn the car on, even before starting it. I don't think the code could be related to the install.

I have a 2008 335i (12/07) build date, manual transmission. The code doesn't seem super common, but from what I can tell it can be a sign of a MOSFET failure on the DME. Can anyone else that has gotten this code confirm that this was the solution?

I see that N54DME.com is still up and offers a repair service (and specifically mentions P30BA and P30BB as the codes that their service fixes). Any user reviews? Sending the DME to them is something I am considering. I just want to make sure they are reputable.

Don't know much about them but you can probably get a local TV /electronics repair shop to do it cheap without worrying about your expensive DME getting damaged or lost in shipping.

Check all wirings and grounds on the head

I thought i was the only one with this code. I have a 1/ 2009 build AT. I originally thought it was related to a faulty injector. I had my engine removed awhile back and i think it was around that time I noticed the code. I think Enrita may be on to something. it's worth investigating.

Does your car drive with this code? I would say mine is not driveable.

Had this code, 1 mosfet was bad, replaced all 6. Problem solved.

Oh and almost forgot, my car started and ran on 1 bank only. Wasn't drivable. My mechanic charged me for 1 hour labor plus parts to do all 6 mosfets after I gave him the ECU.
