My E90 320I
Use INPA to view the list of modules
No CTM modules



But when I use NCS Expert to read _FA, there is a ZCTM module.
I deleted all the VO, but the ZCTM module is still there,
This leads me to restore the factory code of SG_CODIEREN frm3, and the code information is Z4

E89 is z4 which should have ctm.

It seem you are lookin at the wrong Chassis

Maybe your frm was replace with one from e89 that’s why ctm shows up in vo

What do you get when CAS is used to identify vehicle?
Does the stored VIN in FRM actually match your car?

I have executed FA_WRITE to FRM


After guessing, I suspect it is
E89_#0911&LKWT%0A96*LL31$1CA
*LL31 changed my model,
but I don't know what I should change it to

I checked the FRM part number according to the VIN and the FRM is not the original match, but before the FRM is broken, everything is normal.
Until I had the FRM module repaired, they probably broke my vehicle code information.

Read CAS then write that VO to FRM


if that doesn't work you will need an SSD with your factory VO

Yes, I fixed it, got the vehicle FA information through VIN, rewrote the FA of CAS FRM, and everything is back to normal.
