How to clone EDC17CP20 VW Crafter

**Trautec** · 4th March, 2020, 09:34 AM

Hello Guys,

I need to clone a Crafter ECU as said above, but I'm not that experienced with this ECU.
What happened:
I wanted to DPF off the Crafter ECU 076906022M EDC17CP20-2.39A CEBA 0281016822
opened it, read backup with Kess V2, read only Flash, modded flash and wrote the DPF off flash back. When I installed the ECU in the car it dies. The high voltage driver for the injectors shorted through the heat sink/glue to the ECU housing. I guess the drivers are damaged, ECU draws high current and gets warm. So I got another ECU 076906022Q EDC17CP20-2.39A CEBB 0281016820.
I read backup and flash too for security and then wrote the backup of the old ECU.
The car wont start due Immobilizer. Immo control module says, that ECU hast to learn the vehicle an Immo data. But I dont have any PIN.
Maybe this is because of the OTP area not fitting the eprom, as I read in other forum?

The other three files are read with galetto from second ECU after the old Backup was written.

Maybe someone can help me with this files?

If neccesary I will write back the backup of the second ECU and read with galetto to provide original micro, flash and eprom data of second ecu.
And I will try to bring the first ecu back to live with desoldered high voltage drivers to read it with galetto too.

greets and thanks in advance

If you get a dump of the original/broken one with eep then we could just clone the immodata over. From the data in the extra folder i got this:

IMMO Version 4
TPROT_V02.00.00
CS: 99793B8423A051
MAC: EFADD9F4
PIN: 52552

Trautec

read ori eeprom old ecu and new ecu for cloning

old ecu data -----
ECU_MODEL=EDC17CP20
VIN=WV1ZZZ2FZA7004874
IMMO_ID=VWXDZ0J1002158
CS=99793B8423A051
PIN=52552
MAC=EFADD9F4

Thanks for your fast answers

as I wrote before, Galetto reads from second ecu were made after writing the backup of the broken one to it. So I expect the data you posted to fit for the old ecu.

Thanks for the Immo off file.
I will test the PIN Code and the Immo off file, when I'm back at the car. But if somehow possible I would prefere working Immo.
I will provide ori eprom read from second ecu and try to get eprom from the broken one.
Is there any tool or trick to extract eprom data from Kess backup reads? just in case I cant bring the ecu back to life.

Out of interest: which programs are you using?

I can fix it if you have Odis

A friend of mine has odis. What do we have to do?

So, here I finally got Galetto bootmode reads of stock old (076906022M EDC17CP20-2.39A CEBA 88HP 0281016822) and stock new (076906022Q EDC17CP20-2.39A CEBB 109HP 0281016820) ecu.
If I understand right you would clone the immo data from old to new eprom file?
And then I write
-modded eprom
-old intflash and
-old ext flash files
to new ecu?
