Hey, can you use TuneECU to change the service interval and clear the wrench indicator from the dash or can that only be done via the dealertool? I fired up TuneECU and didn't see how to but a Google search implied it is possible.
Yes it's possible alright. I've seen posts on this site referring to it. However, I personally use a scan tool not TuneECU, so I'm no help other than I know TuneECU does do it.
