I was using BMWhat to disable the sidemarker lights on my 2010 328i
after doing so, now im getting an error





The door wont lock, the windows wont roll up, the remote is not locking the door, the dome light wont go out.
Now when I open BMWhat its not detecting the FRM ECU, it says not installed.



Im thinking about trying to disconnect the battery and reconnect as I dont know what else to do.

[Jamrockbwoy]

so I found out how to buy a new one and swap out the old but doesn't it need to be programmed by the dealer?

So are you guys saying the app ruined the FRM? How does that happen?

It can be many reasons.

- voltage fluctuation
- poor quality obd adapter cable
- existing problem with module

etc etc

BMW recommends a stable power supply when diag / coding / flashing

I worry when I see soo many people chancing it without an external power supply. 99% of the time its OK, but people need to be aware of the risks.

I've seen modules bricked even with ICOM A2 being used.

Power supply for the laptop or for the car? Would a battery tender on the car be sufficient?

Why is it the FRM specifically that people so often seem to brick? Seems strange that it's that one module that seems to be problematic.

Also seems strange that there's no way to recover it, either - shouldn't it still be possible to flash it somehow?

any know how to reprogram a used FRM3 to my car? I think im gonna need to replace the module and the dealer is gave me a quote of $800 smh

Well, for one it is probably the most commonly coded module so there is more chance of something going wrong...

If the hardware is intact then id imagine there are ways to recover it. I've never seen an FRM module PCB before but it may have serial / test point access.

I take it you have a pre-lci with FRM?

Its not so difficult. But will require changing some pins depending on what head lamp units you have.

this thread explains it:

Your Lighting module is fried....There is NOTHING that can be done other than replacing the frm module...Its located in the drivers side footwell right behind the latch to open up the hood...

the same stupid app gave me this when I ran diagnostic with 5 other errors

Instrument cluster:
Instrument cluster / Kombiinstrument
Fehler: FRMFA failure / light system fault / LSZ alive failure
Code: A3C1
Fehler: CAN signal fault light system
Code: A3B4

I know its an old thread but wondering whether these errors can be fixed. I've read in some forums that if you update the FRM module, it will clear the error and after updating the module, it needs to be programmed with the car's VIN number.
