Ktag master BOOT read Mercedes W211 Delphi DCM 3.2

Kess v2 master is possible to read Mercedes W211 the 2008 year with ECU Delphi DCM 3.2?

Perhaps not. Ktag should be a better choice to read Siemens/Delphi in BOOT mode.


ECU programming tools i have:Kess V2 + Ktag clone (buy as a kit,saved a lot)


With kess v2 master:


I tried it on my Ford Kuga from 2010: OK

i can read the ECU (just choosing the “Identification” option on the KSuite. The Ksuits shows me the info about the ECU, ok.

I tried it it on a Mercedes E220 W211 CDI 125kw (170 HP): Failed

the Kees V2 said to me: “Wake Up Error”.
I have read about this error and there are solutions about “Format the TF Card” inside or similar.


Note: This Kess V2 comes from a good and reliable seller, so maybe the problem is that this ECU cannot be read by OBd2
It is a second hand car, maybe the ecu it is already reprogrammed or similar.

This is the car list that i have:

ktag-kess-read-w211-delphi-dcm-3.2 (1)
I tried picking in another W211 models, but not works. Same error.


use this cable:

ktag-kess-read-w211-delphi-dcm-3.2 (2)

Read almost all the posts related to this topic. Now i confirmed problem is not kess. i have simens/delphi ecu, not edc16.


my engine bay:The car is from 2008… Facelift

This is the Right side :

The ECU is located under the A/C Filter. At the Left of the Hood.

It is a DELPHI like what i was told:

ktag-kess-read-w211-delphi-dcm-3.2 (8) ktag-kess-read-w211-delphi-dcm-3.2 (9)

Siemens/Delphi can be done by Ktag programmer in boot mode.
It’sdelphi dcm 3.2 ecu.
Need BDM adapter an make a bridge for two pins.


This is what i found, about delphi dcm 3.2 ecu with a BDM100 programmer
