Mercedes W204 2008 - Dash swap

[jaxone]

I have a W204 2008 where the dash will turn off after it gets hot.

Instead of trying to repair want to just change cluster with another used one.
If I buy used cluster there will be warranty on it and can't open.
Can I read 24C128 eeprom on the table trough the cluster connector or not possible ?

Clsuter part number : A2045404548

I have Carprog , FVDI , DP3.

Thanks in advance.

P.S. Alternatively , if this is a common problem for this clusters, is there any repair guide ? Some capacitor broken or transistor maybe ?

Mate, to read that Eeprom you need to open the dash....

[autodiagdoctor]

Yes, you can connect the cluster on bench and read the eeprom by diagnostics. Then just write the eeprom dump in your donor cluster and all should be fine.

You cant just write eeprom data to other dashboard . All you need is to write SSID of original dashboard to the spare dash and of course km stand.
Upload two dumps and we can prepare your new dump.

Thanks.
As far as I understand I can not power up / read dash on bench without a can emulator ?

Pepi: If not possible to read eeproms by obd or bench , then I will have to open up dash. So why not just swap over the 24C128 ?

I can see FVDI has option to read dash eeprom by obd. Safe ?

Hi.
FVDI read eeprom but not all, can not read first 7line.
There is mileage and SSID.
SSID is in fifth line...
Open dash, read 24LC128 eeprom, edit SSID (fifth line) and if new dash has bigger mileage correct it. If lower than EZS don't need correct mileage.

You can write ONLY if your label is 100% same with spare dash. Even then you dont know if was updated dash or no , so better dont do it.

OK, understand.
I will just open up and read eeproms from both. Will post dumps as soon as I get donor dash home. Thanks for headsup !

Attached Redout from ORI Cluster.

[jaxone]

Finally "NEW" Cluster arrived.
It has same part number but I have not connected it to the car to read ID and info.

Attached Defective Cluster 24C128 ORI and New Cluster 24C128 ORI.
Can someone please move KM and SSID from "DEFECTIVE" to "NEW" ?

Thanks in advance.

[jaxone]

I tried to transfer SSID and KM , can someone please check if correct ?
Thanks.

[jaxone]

Well, I wrote my edit on the new cluster eeprom and installed in the car.
After 2 seconds 999.999km appeared

I could start the car.
Then I corrected the mileage in EZS and Dash DP3 and everything seems ok.

Looking at service assist data on the OLD eeprom, this car has actually drove 477.xxx km .... but hey , he did not come to me to adjust mileage just swap the dash.

Thanks everyone for the input, I have learned something new today.

Thanks for the picture, saved me some time.

Reviving old thread ...

I have the same problem. I need to put used instrument cluster in Mercedes W204 2007. Original one is dead. Unfortunately, I don't have OBD tools for this job. Can I:

1) read ORIGINAL instrument clusters' EEPROM (24LC128) to extract SSID and mileage
2A) read USED instrument clusters' EEPROM (24LC128) and put original SSID and original mileage
2B) read USED instrument clusters' EEPROM (24LC128) and put original SSID and 0 km

Which procedure is correct, 2A or 2B? How can I avoid mileage getting 999.999km? I don't have tools for EZS. Thanks in advance!
