Odd. I've never seen a wrench light ever. So you're thinking it comes on in 16,000 km increments? I'm at 33,200 now and my last oil change at 32,600 we didn't do an oil life reset, but we did do it at 24,000 though never got any sort of message or "acknowledgment" from the car saying we reset it correctly. I just figured these cars didn't have the same kind as my SES. I wonder if it will pop up at 40,000 then?
