I have a tool for my Porsche that I can get into the ECU and do a bunch of stuff for about $500. I have one for my BMW motorcycle for about $300. Is there such a tool for Mercedes? One feature I need is the service reset function. None of the steering wheel button methods work for my vehicle.

 

some handheld do that for a hundred +
service reset is not in the engine ecu
it's in assyst

you can maybe even reset it by a combination of buttons and pedal
google
I don't know that sequence if so

 

I've seen about a dozen videos and inquired on this forum in another thread. I even had a page from the manual sent. Nothing worked.
Any suggestions for such a tool? A couple hundred bucks will be paid back after a couple of oil changes.
My dealer refuses to reset it unless they do the oil change. Another reason not to have them do it.
