Hello All,

Good news and bad news,

Good news being that FRM module was replaced by dealer at no cost. And their system will also make them update any other modules to the same 'integration level' ie DDE, DSC modules.

The FRM modules warranty has been extended to 8yrs/125K miles per the SI B issued.

Bad news, is they absolutely do not recognize battery issues and glow plug controller issues could have any relation to the FRM module.

But, they will indeed diagnose all 3 issues separately at the $174 diagnostic fee per issue.

Why the random 'increase battery discharge' messages at times?
Forums searches show that this happens in new and old cars; CAN bus staying awake by module activity? This adding drain/load on battery while parked? Reducing battery life? And then finally when FRM fails, during crank, system voltage will fluctuate by large amounts - indirectly affecting other component (ie glow plug controller)

To be fair, battery had ~5 years of use - so these issues may have compounded themselves.

FRM module by BMW
Battery by me - bought dealer battery and installed myself.
(they do recommend a new one at $482 - parts and labor)
Glowplug controller by me - will buy and install.

Lessons learned : +1 data point for the 'stealership' label;dealer is profit driven; only go to dealer if not tech/wrench savvy; or car out of warranty.

Cheers,

To check your power supply issue you should do two things. Go into INPA and debug the section that has the signals between IBS battery sensor, alternator and the DME to see what is going on. Look for weird values. When doing this take your time and watch it for 20-30minutes and be sure to test it with various loads on the alternator (all lights on/radio/fan/wipers/heated seats and so on). While doing this hook up a oscilloscope and post pictures of the graphs here. This will show if you have a faulty regulator easy. I've seen a alternator/regulator that has been fine for the first 20-25min and then suddenly fail so be sure to take some time when looking at this.

Sorry this might be a bit offtopic, but I'm struggling finding anybody that can help me on this one.

I have an FRM2 in my 07 E91 325d. I cannot delete the short circuit counter for the bi-xenon shutter, and thus I have no high beam. However, I can activate the highbeam shutter with Rheingold just fine.. To me that means there is no short circuit or nor broken wires. But I cannot reset the short circuit counter - it is stuck at 50. All other SC counter I can reset just fine - just not the bi-xenon shutter.

Will writing the eeprom with WiKFP (using the same ZUSB) reset the counter? Or how can I get it to reset?

why cant you reset it?
whats the error?

mate, you've got mistake in first post, it should be 9S12XEQ384 not 9S12XDT384

I do not get any errors, tool32 reports Success when trying to reset it - but it sticks at 50 :/

Screenshots?

Here are the screenshots:

I have a short circuit counter of 50 on the bixenon shutter - I try to reset it with _reset_kurzschluss_sperre 0x20 - and I get an Okay back. But the counter is still at 50. :/

When I do the same for 0x12 - I also get an okay, but the counter is reset.

Which FRM do you have? That command is for FRM1 I think. For later FRM use: steuern_reset_kurzschlussabschaltung

FRM2. (9166709) The command works for other lamps but the bixenon shutter.

I'll try the other command - but IIRC it did not work.

How do you know it works on other lamps? Do you have more lamps with short circuits? The OKAY message simply means the command was sent okay, it doesn't refer to the result.

Yes, I had a few on "STAT_SL_BL_RECHTS_1_SHORT_CIRCUIT_COUNTER" that I managed to reset perfectly.

Woohoo I have highbeams again!

I tried to reset with the mentioned job (steuern_reset_kurzschlussabschaltung) and the same index 0x20 - but got an error. Turned out it needed the text from Lampeninfo. And BAM it reset the counter. I wonder why it worked with the other lamps and the _reset job, but not for the bixenonklappe.

..But I now have a 0 counter and highbeams again. nice!

Nice.

Some lamps share the same addresses in FRM87 and FRM70. You can see the code is the same if you disassemble the FRM firmware and *PRG files.

However some changed.

Anyway, it's good that it's working for you.

Funny thing - the latter function uses the string identifier from the lampentexte - the first uses the address.

Hi,

I need an eeprom dump for my e90 FRM3R PL2 61 35 9390491 -01, so ZUB 9390491

thank you in advance.

This is max brose FRM3? Anyway, I've added 9390491 eeprom to my google drive on post 1 of this thread. Let me know if it's good for you...

yes it is



my frm is not bricked : i just anticipate in the event that it happens during coding

thanks !

So then read it while its fine and you will have backup

First off, awesome thread Sensible_, Thanks for pointing me here.

I started a thread about my same issue (http://www.e90post.com/forums/showthread.php?p=21117779) but was looking for coders. I didnt know it was this easy so long as you have a good eeprom for your model.

So this is now my question, does anyone have a dump for my FRM3?

Info:
E89 E9X LED XE
PL2 FRM3R
S: 6135 9224596-01
SW: 115500 / HW: 05

I still need to buy an XProg from somewhere, but ill find one tonight and hopefully have it early next week.

Thanks,

I've added a dump for that FRM to my google drive. Check link in post 1.

Thank You so much for that dump. Very much appreciated! I'm much more comfortable now flashing the original software on to my FRM. Also looks like I will be buying XProg for sure now and doing it all myself.

I'll also be reading up on all the other software now because it seems I will have to also setup the VIN etc... which I don't know much about yet. If you have any articles or posts for someone who has never programmed a car before, please let me know. Otherwise I'll just search them out this weekend.

Thanks Again.
