thank you

is diagnostic responding to cgw? Fvdi is the cause why this cgw is dead.
Are you able to do SCN coding?

Attached correct fix, try and report.

Repair work only in bench not obd2.

[barth71]

Welcome back. Thank you for your help and I'm sorry to write back so late but unfortunately family life etc. :-)
Of course I will try to download this dump.
The computer only diagnoses with the gateway and does not show any errors.
There is no connection with other systems.
I understand that I have write a dump fix only to epprom and only on bench?
What epprom is in this CGW. I'm sorry but I have a Mercedes problem for the first time and I do not want to crash anything anymore
Thanks

[brend]

Yes,rewrite just eeprom in bench .
Because yours sended eeprom dump active in boot mode.


Eeprom repair.
Pass look in pm.

[mikkhh]

mc9s12xeq384 motorola mcu in this zqw, my second file should be fixed, first file I did wrong, long day at work lol :D . You need good programmer to write this MCU that is it .

[barth71]

Ok, guys. now I understand everything and I will try tomorrow. And report when it works. I hope :-)
Regards

[bersch8688]

Have anyone Manual to read and write with xprog this MCU?

[barth71]

I wrote dump from mikkhh and brend but car is still in boot mode. No indicator , elctric seat etc. and no communication with modules.
Maybe problem is flash. I read flash . I have option in Xprog a D-Flash and P-Flash.
D-Flash is empty
P-Flash is below.
Please look and help me
regards

[mikkhh]

What tool you used to write eeprom ? What tool you used to read flash ? The flash you sent is now corrupt or it is a bad reading with a bad tool... You need good programmer to read write this MCU...

[barth71]

I use XPROG BOX 5.60. When i write epprom and read again is this the same for your dump. However, when it comes to flash, I'm not sure if the reading is ok. Verification in the program is ok but I do not know if it is good. I upload it to the processor in the QFP-112 housing. mask 3M25J. Is it OK?After uploading epprom, unfortunately, it's still the same. Are you suggesting me to use a different programmer?
I am yelling for help

[mikkhh]

the flash is read as wrong size and badly corrupt. Car still responds to diagnostic?

[barth71]

The car start normally and it is just like before. The electric seat does not work, the turn signals do not work, the wipers do not work and the fan works on the radiator all the time. However, there is no diagnosis with modules.

[barth71]

My connection 4 wires instruction from xprog . Pin 23 , 40 ,41,42

[barth71]

I am sorry for so long but I bought the original UPA-S for this registration, etc.
I read UPA eprom and flash again and ask for verification. Is flash and epprom damaged?
Thank you in advance for help because unfortunately I can not deal with it myself.
Regards

[mikkhh]

use eeprom from post #5

[barth71]

ok. i'll try and report
thank you

[barth71]

I write only epprom and i'ts the same . not work. no connection. Maybe flash is corrupt. Please help me repair this file. I really have nobody else to turn to for help :-(

[barth71]

Anyone please help me repair my flash or Maybe anyone have correct flash and epprom from CGW from Mercedes w207 or w212 nr. A212 900 49 11
Thanks

[barth71]

Hello
Can anyone help me with this problem?. I really need help because I will not do it myself. Of course, I have a lesson not to calibrate the dash in a Mercedes but I have to fix it now. Even if someone has such epprom and flash from w207 cabrio or w212 then I would ask, try and maybe succeed. My emailxxxxxxxxxxxxxx
thanks in advance

Here good one flash and repaired eeprom.

Report!

[Pyromaniak]

Thank you my friend, working well. Car is alive again. :applause:

[alarmone]

Hi guys, wondering where the gateway module located w207?

[Thiagobr]

Olá friend, what's the pass from Flash_new.rar

Thanks

[brend]

If eeprom in boot mode , good one flash no help.

Load for check in here full flash + eep .

to this car?

FVDI is well know that will ruin CGW.
It try to flash CGW, probably write tweaked flash which is not working is most case,
however after flashing it issue a reset command that also reset all modules coding in car, too bad.

Actually fixing is not difficult and can be done in car !!
no need to take out and open CGW and solder wire ...
But need some knowledge in Vediamo or something like that, use SDconnect or passthrough etc.
In vediamo CGW/ZGW is in bootmode, just flash with its original or current latest version firmware,
do proper coding if you have backup, or code it manually if you know which code is correct for your VIN.
I fixed this problem a few years ago, but saw this post new :joyous:

[Thiagobr]

FVDI é bem conhecido que vai arruinar o CGW.
Ele tenta fazer o flash CGW, provavelmente escreve flash ajustado que não está funcionando na maioria dos casos,
no entanto, depois de piscar, emite um comando de reinicialização que também redefine todos os módulos de codificação no carro, muito ruim.

Na verdade a fixação não é difícil e pode ser feita no carro!!
não precisa tirar e abrir CGW e soldar fio...
Mas precisa de algum conhecimento em Vediamo ou algo parecido, usar SDconnect ou passthrough
etc. ,
faça a codificação adequada se tiver backup ou codifique-o manualmente se souber qual código está correto para o seu VIN.
Corrigi esse problema há alguns anos, mas vi este post novo :joyous:

My problem came when replacing CGW\ZGW. Everything was ok except the high light that didn't work. I went to do a programming\coding with Autel Maxys 908 pro which failed in the middle of the process and the module crashed. No module does communication.
I've tried flashing with Vediamo. When I go to flash it loads but at the end it shows the following error: "ECU flashing is broken off"

I've been working on the car for days, and I can't solve the problem

How did you flash the cgw ?
Have you turn on ignition ?
Is it an used module ?

However if eep contain bad data may also cause the module fail to run,
In this case will need to write proper data with programmer.

The module is used
I did it with the ignition on.


I read the eeprom and flash with the programmer and apparently the eeprom is good and the flash is bad


Here are the files

Flash with ignition OFF.
Some need to do in OFF.

[Thiagobr]

Flash com ignição DESLIGADA.
Alguns precisam fazer em OFF.

EDITED

It worked perfectly with your tip


I ended up realizing that I was loading the wrong flash
Once I found the correct flash for the part's current SW, it worked perfect.


Thank you very much

Where you get this like , flash is bad ?

Onde você consegue isso como , flash é ruim?


Parsing the file code


The flash code looked corrupted to me

Looks like your W204 is from 2011,
CGW is using 212xxxx
And I think your original CGW should still working.

some modules can be flash in ignition off, actually some should flash in off.
and should check coding in all modules after flash, otherwise there will be some problems or some functions not working.

This problem is kind of easy to fix ! (some coding flashing knowledge is needed)
and can be done in car within 30mins.
If your car battery is healthy, no external power is needed.
If you have online access to do SCN coding it can be done much easier.
A few years ago when I have encountered this problem, no one have solution.
