Self set monitors

Can we self set monitors on a 17 cla45? I?ll delete this post if I get a quick answer but I didn?t wanna buy credits for what can?t be done on this car lol

No. Not possible with any current software/hardware that I am aware of. Somebody might but I would imagine they would be VERY tight lipped about it over the legality issue her in America.

I don't know exactly what you mean by "self set monitors" but I assume you mean the diagnostic system and/or trouble codes? I clear my codes daily but for the more problematic ones I have to use Autel or Xentry to clear them. HP cannot do the tough ones. What determines which are tough I don't know, just that most OBD code checking/clearing devices can't do certain ones, and HP is one them.
I know some codes need a diagnostic cycle to run, and pass, before the code goes away. Yet I can usually clear them before the cycle is complete. Others just need a restart. Which I often do while waiting at a stop light and it's instantly gone. In HP Scanner there is a function that tells you the status of some various cycles and if they've completed or not. It's in the Scanner under Diagnostic, the little engine icon. I've never payed much attention to it, just noticed it was there and the cycle of things were either complete or not complete.

Or do you mean make them never run diagnostic or appear as a code in the first place? I doubt you'll get much help on that since it's illegal in the US, as TheMechanic mentioned, and likely many other countries. HP can make some codes not trigger a check eng light from coming on, but I can tell you it doesn't work on all of them. Why, who knows. I have one fault that triggers with no code or CEL. Not sure why, but maybe that was me disabling it and in reality it only prevents it from appearing? It's either an overboost or torque error, I assume, but whatever it is it kills my boost. Turns the turbos off the moment it happens and a restart is all it needs to reset.

My knowledge on the subject is limited, so all I can say for sure is I blocked or turned off some consistently annoying codes, which I still seem to get some of them, but far fewer check eng lights are triggered. A CEL used to be a daily thing for me, now I'm down to maybe two a week. Hard to say when I turn a code off if it worked, or I simply never triggered it again. But in short, there is a section in HP for turning off codes.

Most that ask this question are wanting something that sets the monitor to complete. A monitor is only a test and not the result of that test. That is shown by a code or a second failed test run to set a MIL/SES

That?s what I?m trying to do. Just disable all reported faults so I have no lights lol
