BMW F30 FEM eprom data lost

[remsia]

hi
f30 after desoldering 95128 eprom all data lost {maybe overheated }
in new eprom i wrote data from another FEM but car now starts only from emergency coil { remote did not works}
i try wrote many dumps from another fem . update FEM with ISTA , but remote still not works
is there posibility to restore data ?
what if i add new key ? remote will works on new key ?
OR I NEED TO BUY NEW FEM ?

Thanks in advance

[drugowaz]

New fem or used fem with keys and adapt. Ori eeprom and keyless wont restore

[khoulioking]

Program new key for this FEM then the car start it should start by keyless, or use the same FEM renew it and adapt it by AVDI

[angyal]

Hi
i had a same situation, i bought new FEM from the dealer....
Other dump solutions not work

How much new FEM? If you dont mind tell.

[rivalryan]

£506 plus VAT.

Also did you program a new key into position 1 or 2 already?

NO NEED TO BUY ANY NEW FEM !!!!!!!!!
find any 95128 dump from here make all programing fem with vvdi2
restore coding
now in car key must start only from emergency coil
next
at first read isn by vvdi from working key
erase key with vvdi
disasamle key
renew key by vvdi key tool or vvdi prog
program "old" -new key with vvdi2
AND ALL !!!!
maybe all that can do with bmw explorer or autohex or anything else
PRESS THANKS FOR WHO IT WILL HELPS

[magneto21]

I agree.
I restored 2 of them, with autohex
almost the same procedure as -remsia

[rivalryan]

I have done many FEM replacements from used modules, DME/DDE CAS ect ect. And to be honest on a scale of complexity this is a very straight forward job just need the right tools. For some it will make no sense to invest in these tools and so a new FEM will suit them fine. Even professionals buy and fit new parts!

in the midle on flashing somethig goes wrong vvdi2 wrotes about error
now wheh fem power on on bench only relay clicking click click ...
with vvdi2 sometimes i can conect to fem .sometimes not but when conect it conect with errors in keys 000000 and ...
when i try to reflash i get error 22 in vvdi2
what are soliution ?

ps soliution to buy new or used FEM i know ..... please do not offer it

what price you have for make key for F30?

[remsia]

Flash it through E-SYS

How i can flash if i cant read fa with esys ?
As my experiance expacialy vvdi bmw like russian roulete
I am thinking to buy autohex as i read its good opinions from users I have bmw explorer and his do not assign my in many years but it do not have update ecus fuctions .vvdi bmw as i try have many many bugs . With esys are complicated to work

Hello there. I have a similar situation and i tried to follow your steps but its not working...
could you help me out?
not sure if its the process i´m doing or if its because eeprom needs to be same frequency of control. in this case its 434mhz.
Can you help?
Thanks

[gabrilupo]

i have same issue, i found another eprom, write it adpt it to car code it, but keyless wont work, then i tryed virginize fem and keys, adapt it and code it, same situation car starts only in column emergency coil.
now i orded new key, i hope tomorrow ill solve issue.
otherwise used fem with keys.

[u.s]

try programming new key and it should work, also if it is manual gearbox you will need to virginize the elv.

[amar28]

For the guys wondering why when a FEM flash fails you cant fix it

FEM has 2x SWFL, they control the ignition, if both SWFL become corrupted then the FEM does
not know when and how to cycle the ignition, this is why you hear the relays clicking, if the bootloader is ok you may be able to restore the SWFL by updating istep, if the BTLD is corrupted then its likely a new FEM

if only 1 SWFL is corrupted and the other is ok then the FEM can be restored

[drugowaz]

When relay click theres no communication with any tool.

[amar28]

Strictly speaking thats not true, when the FEM/BDC solution was first introduced many tools had a problem whereby the original coding could not be restored, when this happens it also starts clicking, no ignition etc, easily fixed with esys. This can be seen on yanhua threads where people were complaining that the coding data cannot be restored hence why yanhua released the engineering menu, same with DP4. This is from my experience of working with many FEM/BDC

[drugowaz]

Im not talking about coding or eep lost. This not matter. Im talking about when flashing process and flash erased corupted in bga chips,power interupted etc. Its gone. You can do anytjing you want module will not comunicate with any tool. This is already tested with many tools,istas pistas huistas not matter. You will not be able to restore it. If you know how to doit ,write manual how to amd sell. I will be first who buy it

[amar28]

A few days ago, Doing FEM on bench, Power supply cut at 60% upgrading, Vin = YYYYYYYYYYYYYYYYY, Key frequency: kein frequenz (no frequency)

fixed in 20 minutes all working fine, As i say if bootloader is there then any ECU can be recovered, If no bootloader then your likely in trouble

Hi Drugowaz, I had same problem I damaged FEM 95128 with heat. i have no backup file for 95128.

it there ant step by step solution fon instructions you can provide. Thanks in Advance

[drugowaz]

Read from beginning. Experts write hot to. After test ,report

Hi,

I burned EEPROM,maybe with overheat.
Now, I will write an EEPROM from here, but following your steps I have a question: what is "restore coding" ? I will write dump on EEPROM, mount FEM and after programming keys with AVDI, right? I don´t understand "restore coding"...

Thank you!

You can go to (vin.help) make account and download FA and VO as per vin for car... Then proceed to flash with e-sys...

Very helpful site when FA and VO is lost when people swap parts from different vehicles.

Goodluck...

Hi

I found at least two people saying eeprom got burnt. Is it some special eeprom that is less protected?
or is it glued?

Or some other thing ....

thanks

It's glued, in my opinion it's better not removing from pcb

[p1et]

It's glued, in my opinion it's better not removing from pcb

But many other eeproms are glued also, especially from Trucks ECU's and I never heard anyone burned eeprom, maybe broken/lifted soldering pads but not damaged eeprom. There must be something odd in those FEMs eeproms because I heard 10+ times somebody lost it's data after desoldering or eeprom just snapped in half :o

Personally I don't do FEMs, for me it's useless to do it as key from dealer is almost same price as people offer and it's much risk. I can do if AKL because then time matters but spare key, hell noooo, not for me.

There are at least 3 steps when you can fck up.

1) reading eeprom - you can damage while desolder or you can read wrong data, either using clip or after desolder. Known case here when some tool just read this FEM eeprom wrong and in this case you don't have original backup so when you modify file, and write, you messed up
2) reflashing process will interrupt
3) original coding won't restore

That's too much for me

[jodge]

i always removing from the pcb only with soldering iron +scalpel + plier and never ever with hot air nor IR (cool stuff tho). For me it's easy job and for me the only safe way to make a solid backup.

[fuzz1]

Maybe as some suggested it should be read in circuit with just the capacitor removed to prevent it from switching on. Soldering on the eeprom legs. Clips tend to be hit and miss

Personally i do it like this, but everyone has his own method..

[jodge]

interesting way, did you removed something from the power line or similar?

[Antonio266]

Nothing removed, readed in circuit with ABProg and ZN057 adapter, the one in picture was a BDC from F45 2018.
In the last months i'm doing it this way and so far all ok

Good option that page colleague!
Can you help me with an invitation code so I can register?
I think it's a requirement to be able to do it...
Thanks

[electro10]

Many thanks to all.

Sorry by duplicate post, but I started my situation on another thread and now I explained how I solved: https://www.digital-kaos.co.uk/forums/showthread.php/942498-BMW-F20-FEM-EEPROM-damaged

About the unsolder process, I don´t understand how EEPROM was dead... I unsoldered many many components and is the first time. I have ideas to buy the AVDI adapter to read in circuit yes. But read in circuit with AVDI / Abprog is the same to read with xprog for example, isn´t?

thank you

Very good opinion!

In my case, I solved with AUTEL tool....

I'd like to know also :) I think it must be difference, that's why people say with VVDI Prog need in circuit eeprom adapter, can not just connect to standard socket:

Yes, is my opinion too. But the ZN031 is 100€ + 10€ of ZN057. They have, on ABprog manual, connection to read directly the EEPROM with DB25 (without ZN031) but the voltage is always +5V and in FEM I didn´t measure the power supply of EEPROM

To keep the risk of damage to a minimum, you could use something like this.
I added keys to 2 FEMs with no problems.864771

Which tool do you use?
But this adapter is a "passive adapter", right? Is only to easily solder wires, right?

Thank you

[lion0304]

I've never read eeprom wit xprog or VVDi prog.

Because i tested one time read by xprog, data is diffrent than i read with my TL886 (alway use this)

For eeprom out circuit: TL886, sometine in circuit: Orange5 (TL886 doesn't support in circuit)

I also in backup UPA, autel, X100 pad2, Carprog, willem in case if proved tool doesn't work.

Last thing, i don't like the all in one tools, that could take a little more time but every step is proved (less risk)

Do you guys know if it's possible to flash FEM over DCAN with ESYS or ISTA? I have this car where ENET communication was working fine, performed a repair on PT-CAN, and ever since then, ENET communication has stopped working.
