How to choose a good Op-com Opel diagnostic tool?

There are many versions of Opcom firmware running with vaux-com 120309a. but what should you take Here I will chip in some words and hope it helps.

the first photo: opcom fw 1.95

the second photo: opcom fw 1.70

the third photo: opcom fw 1.65

the fourth photo: opcom fw 1.59

the fifth photo: opcom fw 1.45


Look here:

Reply: The last official firmware is 1.64

Check also the official and you will see there the newest firmware version that it will come in the new version of opcom and it will be fw1.66

For vaux-com 120309a you need only opcom fw1.45
Even you are using the fake vauxcom 120309a+131223a version you need also fw1.45

Not any newer. But you can use any newer versions of firmware but you will have nothing new and it will not help you more then fw1.45


The most important is to have an original PIC chip that can program new firmware.

So, if you wanna have Opel diagnostic with Opcom China clone, forget the firmware version (new v1.95 or old v1.45) and check if it’s with a PIC18F458 chip with the vendor. That is the most most most important!!!!!!!!! Anything else is secondary.


You can find that there is a PIC18F458 chip in all versions of Opcom china clone above. So use Opcom and vaux-com 120309a with relief.

Either kess EU or kess China isn’t original Alientech Kess V2. if you want kess v2 original, please go to


You can use Kess v2 with relief to read or write ECUs

All kess work, esp. kessv2 china clones (tested 100%)

connected to the car, read data very fast. Works fine.


Look here: Kess v2 5.017 is working great with a 2007 BMW 323i 2500 24v N52B25, ECU: siemens msv80.

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 ….  !)
