Why Kess v2 5.017 firmware is populous now?


First, Kess v2 is the latest version. People usually are curious about new things.

Second, it has better stability when running

The last but the most important, it has the biggest compatibility with other versions:

– works on cars, trucks, tractors, bikes, not cars only

– No token limitation for ALL vehicles

(the old versions have token limitation on some models)

– FULL authorization of ALL software protocols: add 140 protocols in 5.017 version

(works well for EDC17/MED17/k-line/DSG/DQ200 DQ250 DQ500 Gearbox/ST10/Ford J1850 ….  !)

How to solve Kess v2 ksuite “Protocol not compatible”

Here is a customer solution of Kess V2 Ksuite v2.22 protocol error “Protocol not compatible with version FW”. Put it for sharing. Wish it helps anyone.


The customer bought SE87-C (kess v2 master v4.036 ksuite v2.22).
He got the error message“Protocol not compatible with version FW.”when trying to read a Audi 2,0tdi 2007 BRD engine. Ecu: Siemens PPD1.3 I
I have test software version 2.06-2.22 same problem.

kess-v2-ksuite-v2-22-protocol-error-1 kess-v2-ksuite-v2-22-protocol-error-2

Then the customer have successfully solved the Kess v2 protocol error himself.


He said as below:



“I have solved the protocol error myself.
Here is how: I installed the ksuite 2.06 full, then copy the ksuite 2.08 who is in the token reset folder that has the firmware's in update folder into my install directory. (like you do in the video for the ksuite 2.08)”

Kess V2 Bench cable or OBD cable, which for MB temic truck cables?

Any doubts about MB temic cables for Kess v2 tuning work? Bench cable or OBD cable?

There are some differences between the bench cable 144300K249 and the obd2 cable 144300K251:


You can not clone ecu from obd, for that you need bench cable.
Old boot cable works only on boot mode and does not support new continental ecu without flash memory.


So buy just two head (round + obd) Temic truck cable (with part number 144300K249). That is your choice for tuning.



This cable has been done on 200-300 MB trucks by a user, first in boot mode and after Kess v2 released OBD protocol.
Never had really any problems.


It’s easy to find with Google search seller from China sellers or other who sell euro clone Kess v2 or Ktag
But you have no this ecu tool now. Better to buy a Kess v2 truck version. It is a truck specialized version. Compared with other kess in markets, this truck version adds a lot of ECUs for trucks diagnosis and ecu programming.


Kess v2 truck tuning kit price: €64

Version: software V2.08/V2.22, firmware V4.024
