Bm3 codes

Anyone know why these are popping up? Using multimap custom rom currently running 91, car seems like it went into limp, steering wheel got hard to turn

FlexRay seems like it's fucked up. I've never actually seen that happen before. FlexRay on these cars controls power steering, ABS, and some transmission functions. It's part of the security module. Flashing a map won't/shouldn't do this.

You could have a little rodent that chewed through something or some bad wiring somewhere.

Any idea where I should start looking at first for troubleshooting?

Control unit is dead or wiring is bad to it. This is dealer stuff if you don't know what you're after.

Ahh would definitely like to avoid dealer since I have bm3 and fbo

Check your wiring and see if you did everything correctly.

Edit: did you install a flex fuel kit?

Yes I installed bm3 flex fuel kit

Did the codes show up after install?

Yes I installed bm3 flex fuel kit

Are you able to read the E content via the dash? If not it’s possible you swapped the wrong subconnector.

By dash you mean on the rpms? When i press down it moves the needle to 1k which would be e10 for me since im on 91 rn

Mmm do you know possibly what part? Because I watched the bm3 install video step by step and made sure everything was on point

disconnect the Flex kit, clear the codes, and see if they come back.

I've had some crazy flexray errors when wiring stuff wrong.

so far ive cleared the errors and havent changed anything yet they havent came back

I was messing with the live adjustments burble overide and noticed the burbles weren’t changing as I was driving then thats when all the errors hit so I thought it had something to do with that??

Any chance you forgot to disconnect the battery before install?
