I got the 30bb code a couple weeks ago, tested the mosfets to find the one for injector #5 was bad. I had all six replaced and put the DME back in to find that the car will only crank but doesn't start. I'm getting these codes.

Is the DME fried?

Did you check power to the DME ?

[jjla21]

How do I test that?

[jjla21]

I have in a sense I suppose. I first reinstalled the DME with the JB4. When it didn't start I tried changing the map but I couldn't access the menu on the gauge cluster. So guessing the DME is not getting any power.

I then tried installing DME without JB4 which made no difference.

check every fuse

I know of the 50 amp by the power wire and the fuses behind the glove box. Are there any other locations?

Did you replace the mosfets by yourself or had someone do it? I'm curious as to whether the copper underneath was ripped off. I so then no power would get to them.

I had someone else do it. I could talk to him about it. Would he be able to repair that or am I out of luck?

There are four or five fuses in the dme box

I've read threads that showed a pic of these fuses, but I swear I don't have these. I'll take a pic of my ecu box once I'm home.

Dam man..same thing happend to me...I replaces 2 mofsets and recently had the same codes..2acb I found the dme master relay...it's a blue relay inside the dme box on the same side as the little fuses box in there also. I'm going to replace today and see if my car works...keeps shutting off on me.I have a friend that is very very good with dme mofsets and coding etc. Gregory latchman..out of queens I'd hit him up if I were you +13475283962

Trying to show pic on where Is but not uploading...347 599 3009 text me I'll send u them and where it Is and the dme relay also

This happened on my 135i. The DME board was damaged when the MOSFETs blew and it required an entire DME replacement and IJEOS conversion.

I'm thinking that may be my issue. I just would like to test all fuses and relays first as that has seemed to save some peoples asses. Just need to find them. My 08 335xi seems to be different in the ecu compartment in that I only have one fuse and one black relay in it. Where most people I've seen have a blue DME main relay and a small black box of 5 fuses.

[jjla21]

Anyone with an 08 that can take a pic of their ecu box? I do not have the fuse carrier in mine, the one that says motor scherungen on it.

[longnvu]

Here's mine

Thank you. I'm amazed at the fact that I don't have that fuse carrier.

I know this post is old, but how did the OP fix the problem?

I bought a "remanufactured" DME from rpmmotorsport.net and haven't had any problems since. It's the cheapest way to go. I also had to replace 2 coil packs.

Hey man ! My box is exactly same as u. Finally did u find the blue relay? I want to replace a new one to have a try. I got the 2ACC too... really need help! thanks a lot!
