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.

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

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

**barth71** · 27th September, 2018, 01:02 PM

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

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** · 27th September, 2018, 04:00 PM

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
