Help: 335i Crank, no Start lot of DME error codes

dmikhael619 · 11-05-2019, 10:29 AM

Could use a bit of help. Car is a single turbo N54 was driving fine all day parked it at night and now it wont start, it just cranks over. It seems to me like it is a DME failure but I don't want to throw parts at it so any help would be appreciated I attached some pictures of the original fault codes that I got then I cleared them and got almost of them back. I removed the JB4 to narrow down any culprits. I originally tried to read codes through the JB4 but I could not connect and I could not access the steering wheel controls either. Only way I was able to see the codes was through the OBD port on MHD. I attached images of the error codes in the link Thank you !

I tried and got almost all the same codes. Im 90% sure my DME is toast. I bought an MSD81 for 200$ and a local coder is going to clone my old one to my car for $300. Will update the thread if that solves it just in case anyone else ever has this same problem.

i wonder if your timing is off? I had similar issues, i updated my MSD and it wasnt that. My problem was my timing...

dmikhael619 · 11-07-2019, 01:39 PM

I hope not lol this is my second motor already, Did you get the DME failure codes? The really weird thing was the car was driving 100% fine and then just ddidnt want to restart the next morning. Also when I tried to connect to the Jb4 bluetooth I had no luck and the steering wheel controls did nothing.

Have you had the battery load tested?

dmikhael619 · 11-18-2019, 12:23 PM

If anyone is interested I put a new DME in the car, put in a new engine harness, check every ground, a new JBE module. tested my relays and still no luck. Same codes. I'm pretty much done with this platform. I will be buying an F80 next weekand will be doing a full part-out of a 6mt N54 Black sapphire e92. Doc race 6266 kit makes about 730 whp has about 20k in mods done to it will be listing everything soon. Thank you to everyone in this forum who contributes!

I am very sorry to hear that you will let go of your E92.
Best of the luck with the M3!

Your issue is error 2ACB, which refers to the fact that the dme relay does not open. Fix that and you will fix your issues. That DME relay powers more than the DME. If JB4 was removed properly.

Make some pics of your fuse panel, also, I suggest that you hit a little the fuse panel and try to start the car.
