Ok, so stupid question: Which one of these do I actually execute after an oil change? I tried a couple, but I still get the "oil change needed" message on the instrument cluster when starting the vehicle.There are 2 things that should be reset after doing an oil change..
Both can be found in the Multiscanecu tool or done at the dealer.. One is the obvious Oil Change Service message, however the other one in the Scan tool (under the Engine section) is to reset the the adaptive parameters of the UniAir control module. The dealer is supposed to do that as well. The UniAir system deals with optimizing combustion and the variable valvetrain and the fresh oil changes those paramters based on oil thickness and evap amount or something of that nature.. Power wise you probably wouldnt notice a change, I think it has more to do with engine effiency and evap, none the less, I always reset the module after an oil change anyways..
