It's well documented that the SGW does get in the way of MES, both on MES site and in the application itself.Yes, I saw that also. There are a couple variations of the method but none of them have been verified and attempts at replicating the "procedure" haven't been successful.I believe the SGW blocks all diagnostic commands, and the oil reset would be one of those.
I do recall recently someone posting in this site a reset procedure that involved depressing the brake pedal and ignition switch in some order/time. Don't think anyone has confirmed if it worked or not.
If SGW gets in the way of MES I will be very disappointed. I have a few e-mails out to other OBD2 diagnostic/reset tools and none of them work to reset these lights.
