Hello, firstly I have BMW e90 pre-lci 320d 2005 year.
When i bought it the reverse lights didnt worked. Firstly i thought it will be the gearbox reverse switch - we replaced it - nothing happened (still no lights).
Yesterday I fixed the wiring in loom etc. My friend connected pc and restarted FRM module (reverse lights came back to life).
We thought that PDC will came back to life with reverse lights (because of wiring short circuits) but its not.
Today my friend came back and connected pc again with toolset32 (or something like that) he manualy turned the PDC and they are working perfectly (all four).
After some time we noticed that the digital data shows - "reverse off" even when the gear shifter is in reverse and the back up lights are on.
So to sum up:
New gearbox reverse switch
Fixed wiring
Reverse lights are working
PDC fuse are ok.
PDC are alive (PDC module shows the data etc.)

Any ideas guys?
Maybe someone got into the same position and know the answer or the way out of this?

But how this could be true. My friend checked the modules and everything looked okay. Does the FRM block have something with reverse position seeing? I mean to see when reversenis engaged.

Hello again.
So I bought used frm2 its: FRM 2 E90 E91 NSW / BASIS
I installed it into the car. My past frm is like FRM1 or smoething like that. So when new FRM installed: all lights are working, but PDC problem is the same, and now I also have mixed driver electric windows switch press drivers - opens passengers and so on.

Do I need to code something to fix this ar PDC problem or this is faulty FRM as well.
Thanks for help.

Can you answer?

I would imagine it will need coding with your vehicle options. I used Ncs Expert and Ncs dummy using guides of here i think.

I coded it now everything is okay about FRM but PDC is still in the same position
