I'm inclined to agree with FCobra94 that the Lambda sensors might be giving bad readings. BTW, the car has 4 oxygen sensors, 1 pre-cat and 1 post-cat for each of the 2 banks. The Pre-cat or Lambda O2 sensors sit right after the turbo and provide the readings used to dial in air-fuel ratio. The post-cat O2 sensors mainly ensure that the catalytic converters are working, though they are thought to have some effect on AFR calculations. The makers of the downpipe fix (which doctors post-cat O2 readings) actually warn that it should only be used to pass emissions, since it can interfere with AFR.

Your current problem defies simple explanation. Your AFR is scary high, yet the car seems unable to correct it. You have very good fuel pressure, and your injectors are brand new. Still the fuel trims are totally maxed out, and the car continues to run lean. My inclination would be to flash all the way back to stock (not map 0, all the way back to stock), clear adaptations, and see if things improve. Going 100% stock also ensures that the dealer can fully diagnose the car, and prevents them from blaming everything on your tune. I'm inclined to agree with the guy in the logs thread who suggested that MHD might have a problem with your altitude. That is another reason I would test a stock configuration.

The 30BA/30BB is another mystery. Statistically speaking, a failure of multiple injectors/mosfets on multiple banks is highly unlikely.
I would flash 100% back to stock, drive and data log until problems appear (leave the codes stored on the DME), then take the car to a dealership or highly regarded independent for diagnosis.

BTW, the DME is simple to remove. Just pull the cowl at the bottom of the windshield to get access to the E-BOX, slide the locks to open it, undo the connectors from the DME, and slide it out.

First of all thank you for all the information!
I left the car at home today and took our other one so I won't be able to do anything until tomorrow.
Once I get home I will completely remove the MHD tube and drive around and see if things improve. If not I will take photos of the codes and go from there

I will be contacting my local BMW dealer and setting up a full diagnosis because I can't keep going back and forth with these issues. It's one thing after another for weeks in a row now.

I'll have them check/verify the O2 sensors and I will try and remove the DME and check the MOSFETS to determine whether they're good or bad. That will hopefully shed some light on these issues.

Also when I call the dealer I'm going to ask about the DME warranty which was 8yr/80k but I recently read that it was changed to 10yr/unlimited mileage (will have to confirm)

They were great last time when I had my HPFP/Turbos replaced so hopefully this time they're just as good!

Since they were replaced recently why don't you check the harness on the injectors? I suspect faulty ground. I have seen this before. Also, are those new new or cheap "refurbished" injectors? The ECU is probably damaged too. Go after the shop that replaced the injectors.

Called the shop who installed the brand new index 12 injectors, they said they have installed hundreds of injectors and codes as well without issue. They also said if they were installed incorrectly that they wouldn't work at all? Again this is what I'm being told not my own words/thoughts

They would work but would not work properly which might explain the maxed out fuel trims, running lean and O2 codes. Additionally, your ECU now shows 30bb/30be for internal ECU faults and injector activation codes on injectors #2 and #4. Try to move the brown wires on the posts between the injectors. See if they are loose. Regarding the shop installing hundreds of injectors...well I have a good joke, if interested to hear it I will share.

I will have to check all of this tomorrow. I won't see the car until then. They asked me if I had experienced this before they swapped them and I said no.

Don't have a battery charger to flash back to stock today, Amazoned one and it will be here tomorrow.

Will have to wait for that. In the meantime, ill have to check the brown wires and yes I would love to hear a joke!

You just need a better diagnostic mechanic. I have a 2010 as well and sometimes problems are a result of a root cause.

If it's that much trouble, just get it running and sell it.

Funny story,l actually had it for sale and had a buyer, but after I spent 7k in maintenance and repairs I had second thoughts and didn't want to take that much of a loss and now it just keeps coming

As for a better mechanic, I'm going to take this to the dealer. Sure its $186 for a diagnosis but at least they have top of the line diagnosis software and mechanics to actually tell me what the issue is instead of going back and forth with guesses, etc. Just nee my battery charger to come in tomorrow so i can revert the car back to stock ECU and completely remove MHD and go from there....

Sometimes you just got to bite the STEALER bullet.

[AMG_KLR]

Update:

I just finished completely removing the MHD software from my car. Completely uninstalled.

Everything was good to go 100%.

Disconnected the battery charger and went to start up the car...NOPE

The car won't start now.
It just cranks and cranks...

MHD cleared the codes and when it wouldn't crank I checked them and this is what was Present still?

[AMG_KLR]

Ps: the iDrive says engine malfunction when trying to start?

[AMG_KLR]

Update #2:

Car wouldn't start. Read a few things and said to try reflashing to stock again. I did and this time left the battery charger connected and tried to start up

It hardly started to but it was instantly running like shit (misfire style) and the iDrive said engine malfunction again and then I turned it off and tried to restart and it wouldn't. Great.

Now I'm reflashing back to Stage 2 just to see if the car will even turn on and if so I'll try to remove flash again and go from there ... any ideas of why this is happening?

Was idle rpm bouncing?

If so do throttle adapts reset using accelerator pedal method.

I don't recall all i remember is saying what the fuck

[335e92tx]

can be quite common after flashing and changes. And it will code immediately and stall.

Reset throttle via MHD and car started but sounded like shit just like before. Turned off and went to turn back on and same story. Won't start.

Car is reflashed back to MHD Stage 2 and again still won't start

The other way you mentioned to reset throttle won't work because this is push to start not keyed FYI

Yes, because you ECU is toast.

What makes you say that? The car started up fine yesterday

Because ECU is showing 30ba/bb. That is internal fault and ECU can't drive the injectors. I told you this few days ago.

It's been said multiple times...since "it's not too common" on his MY, no one else seems to suggest starting there first though; codes or otherwise.
