Flash this file, it is your original file with only DTCs off, the checksum is ok.
Blank the EGR with metal plate.
If you disconnect the EGR plug, there will be an error about "EGR basic setings not performed", but the MIL will be off...

Oups... i've forgot the file...
Here is it!

Hi Bobo, unfortunately car didn't start with this file. Even check engine light not light, like bad soldering, but I test connection few times.. Will try with ori and your again, but I'm afraid that something wrong in your dump. BR

Hi friends,

It was not cs problem but file from wrong ecu (first installed). Now I attach file which starts car ok, but this P402 problem. Please check this.

Winols swapped bytes and after conversion I don't know programmer will write file good.

Flash this file.
DON't touch anything!!!

BTW... P0402 and P0401 are not present in the DTCs structure, so they can't be erased from the file.
BTW2... P0402 is made to P0000 as i saw just now, so your file is not ORIGINAL... AGAIN...
Any way, my file should be ok.
