I've not had mine updated for the fan either. It's some kinda glitch. I read 2 years ago that if you don't pause with key and just go straight to starting the machine, the fan will come on like its supposed to. I've made sure I've done that ever since and I've not had a problem since. I'm at 7000 miles now. My friend has the same machine. I told him about not pausing a couple different times. 1 day on a ride with him, I watched him pause and then start. I never said anything cause I didn't wanna sound like his daddy. About 4 miles down the trail and he was boiling over because the fan wasn't running. He not had it happen since. It won't do it every time u pause. Sometime in 2019 they came out with a fix. Good luck.
