ML 350 Bluetec 2012
Big Problem with DPF/EGR/Bluetec Off !!!

good day, I have a problem, maybe you can help me, I'm from Germany and drive a mercedes ML 350 bluetec 2012,
( Bosch EDC17CP46 )
a tuner from here disabled me AGR DPF Bluetec off and now for months the car goes without performance and if i do kickdown in limp mode, but without codes.
when i turn it off and on it works great the whole Time, but when i switch it off again and turn it on again After Some Minutes the same problem with limp mode, turn it on and off and it works great again.
I have to start the car everywhere I am 2 times.

I disconnected the nox sensor under the car, and staked the Bluetec ECU in the trunk and of course made the DPF empty.


No one here can help me !

do you know why it can be?

Do i forgot something to disconnect ?

do I have to stake out something from the AGR?

Thank you very much !!!

If the issue started right after the retune, then the tune should be suspect
