mb w204 crd3.10 failed obd writing - Trys2penki - 07-02-2022
Hi. ive got a problem. I was doing dpf off for w204 om651 crd3.10. Disabled dpf in coding section with vediamo, read flash, disabled dpf in flash, write it back, and kess gave error on 100%. now no response from dme. Put original flash on table with boot mode, still no response from ecu. Can someone help me? As far as i know eeprom is corupted.

read all with ktag and post the two files from obd and boot read, but i think you killed it more with the obd write on boot. you need boot read and write. if you write obd read by boot you are in a worse situation then before

what i did on a sid 211 is read in boot and compare obd read with boot read and fix file then upload the fix file see if that helps you

its org file obd read, dpf off file, and dpf off file boot read.

try writing original file in boot as boot and obd files looks indentical so it just might be checksum calculation problem (other possibility is that kess wiped int flash completely and written just obd part)
first write obd read (original file not dpfoff !) in boot and try

he did that, so my guess is as yours , int flash is wiped and only the obd part is in it

yes, ive done that, nothing. today writing other files from other ecu with same p/n.

whether delphi has virutal eeprom in flash like MB edc16 ?

you are missing lines from 1FFFE0 to 3744EF
Here file that i have closest to yours, not lose anything to try. Write with ktag if you have

You are absolutely right. Write flash from other ecu with same part number, write original eeprom of my ecu, car runs fine.
Problem was not in corupted eeprom, but in failed obd read that was mising some data like You said.
