Interesting ...........
Mine use to do the "Random Reset" routine as well and I got use to not using that function.
What I have found recently, however, is a little step that seems to make it work and reset only at a fill-up time?;)
What works on my car is to have the "Miles Since Refill" actually showing in the "Data display" when filling up the car and before leaving the pump and driving off ...... cycling through the available info screens and returning it to "Miles Since Refill" and mine resets as soon as I drive away, as it should.
It’s been working properly and consistently when I do those steps. Give it a try. I’d be interested to see if works for you guys or is just a fortunate idiosyncrasy of my car?
