Hello there guys! How are you all doing?


I'm no expert, but I really enjoy working on my own car, and this forum has helped me in more ways than I can count.

I had a problem with the FRM3 module, on my E90. The car tried to start with a dead battery, which as you all know can cause the FRM to crash and become corrupted, which happened.

I have done my best to solve this without bothering anyone for help, using all the guides and posts I could find. A very good friend was kind enough to lend me a UPA v1.3 flasher, non-genuine version.

I was aware of the risks of using that flasher, but it was already bricked so I gave it a go.

I had converted the file that was in my car, using the online tool most people do. But then the fog lamps wouldn't turn on. I searched online for a dump that matched my SW and HW, eventually found one and it took a huge amount of attempts to get the flasher to write to the whole memory, but it eventually did.

From then, the fog lamps still wouldn't turn on. Went back to search more online, which made me NCS code the module, a lot of times... No success... I wrote the VO/FA, and also tried coding an empty file to force the module to program itself based on the VO.

But still guys, the car won't turn on the fog lamps, and I also get an error that it can't find the Potentiometer Dimmer. My car has the "digital dimmer", on the dashboard, and not the analog dimmer.
So, I came to the conclusion the software is for the wrong Chassis.


I even tried to find my way around WinKFP, but I couldn't find a Z number, got overwhelmed, and gave up for a while. Now I'm back on this hahahah, and I mean, there must be a way, right?

There's a problem too, I don't think it's wise to try to flash again using UPA, and I don't have the resources to buy a good genuine programmer now. I'd really like to be able to fix this from OBD.

Can someone spare some time to help me out? I have already attached the photo of my SW HW.

I will be firing up my laptop with the files I flashed, so I can sort them out and attach them here too. If there's anything else I can provide, please let me know guys.

Thank you all very much, in advance. I hope this can be fixed! Even though it's not completely broken, I think everyone here can appreciate the importance of tidying up our cars.

let me understand well. did you put a dump of an equal frm? what software do you have? if you still need I can try to help you.

Hey guys!


So, I found the file that I flashed to the FRM, I'm attaching it to this post, it's the file named "PL2_FRM3R_6135_9224596_SW115500_HW05". By the name, it is supposed to match the one you guys sent actually.

I'm also attaching what I think is the corrupt EEPROM I extracted back when the module was fried, it's labeled backup.

Arual, thanks so much for offering to help too! Yes, I flashed what seems to match the module I have. I have access to NCS Expert and WinKFP. I have tried to copy the FA from CAS, but nothing changed. Is there any other information I can give?

If anyone else feels they could also give some input to help, please do. Thanks a lot!

Guys, I went back to WINKFP, trying to program the module from there. From Comfort Mode, I chose the FRM3R, then entered the VIN and tried programming it, with a charger connected. I was then presented with the error in the image attached.


Also, I tried to get some information from WINKFP, on the two OUT files attached. As you can see, there's something wrong there
