This started as a request,
but wanna share it with you ALL here on DK

Here is how to : clean ASSYST Plus Memory
All we need is DAS in Developer mode :devil:
In Developer mode : (tested version 07-2009)
Steuergerate (Control units) ->F3
Aufbau (Body) ->F3
ZGW (CGW) ->F3
Entwicklungen (Development data) ->F3
Steuergerate - Anpassungen (Control unit adaption) ->F3
Programmieren (Update) von Steuergeraten (Control module programming) ->F3
Steuergerat programmieren (Auswahl) (Program control unit (Selection)) ->F3

Now we have 2 options to flash the ZGW/CGW with, choose the correct one :)
Don't panic ! if you choose the wrong file , it terminates process and you can do it over again
Confirm Flash pop-up with Ja (Yes)
After that it says : "Das Steuergerate wurde erfolgreich programmiert"
-> "OK" it ask for a reset -> JA (Yes) ->
ECU Reset (FN_ECU_Reset) ->F3 again ->F3

Now you Completed full History wipe out :beer:
Everything discussed in this post is for experimental and educational purposes only
If you think this would help you :wink:

Thanks for sharing this DAS Dev. procedure......

I was wondering if is possible to wipe out all the services and then create the ones I wanted to show or with the DEV mode there is an option to do selective erasing of those services.

Thanks!!

I tried it with DAS 11.2010 and it's not working...

I'll test it with DAS 05.2009and I'll report.

How long is the programing proccess? When I click yes to programm, in less than a second DAS says that programming is OK. I reset ZGW but service data are still there.

Turn the key to position 2 in the ignition lock and immediately press
button 000.0 twice within the space of one second.

Turn the key to position 0 in the ignition lock.

Press and hold button 000.0 Turn the key to position 2 in the

tryed it and it works great , but i think only on mercedes cars that stors assyst and assyt+ in CGW , but newer models that stores assyst and assyst+ in instrument cluster doesnt work so i think there must be a way to clean assyst with DAS in newer vars like 2009 c350 body w204 , does anybody have a way to do it ?

qrius procedure will deleet all services in CGW , this got nothing to do with your mileage in speedometer ,the mileage will stay the same and service will be service A in 20000 km

I have try in dev mode with das simulation, and for Program control unit i have only 2 variants in selection:

v13.04.03.24_taxi_ab_A''J03/x, Taxi-datenstanz ab SW-release 01.02.00
and
v13.04.03.24_taxi_ab_A''J04/1,Taxi-datenstanz ab SW-release02.00.00

I think is not the right coding because this car is not a taxi car.
I insist on this problem because i don't have enough experience with star and i don't want to destroy something.
thanks in advance

doesnt matter wich option you use either one , if your car doesnt support that option,DAS will not let you contenue procedures , then you chose your other option ,
done this about 10 times already and never had any problem ,
trust me Qrius he KNOWS what hes talking about all credit goes to him

At newer of w211 models be ware this solution can cause oil light fault.
I always make an backup of CGW before I reset.

There are no oil light fault, and unfortunately I didn't make any back-up. Now the mileage and everything else is at zero.Someone knows how to enter it with Xentry DAS.
