your best bet is likely to just focus on the offsets. If you want a set of winter wheels, no better than just getting the base stock wheels. plenty abound.
It's not just how you drive, but also what settings you have on. For example, if your AC is on, you will lose range. If your heated seats are on, you will lose range. If you drive highway speeds with the windows down, you'll lose range which will eventually show up on your guess o meter.

how is your cell signal when it's not showing up? I've only had that at PCM start up and/or poor cell reception (at least I correlate it to poor cell reception).
You've finished a soda. You're holding the can, you squeeze a bit too much, it dents. You rotate and squeeze again to pop out that indentation. That sound it makes when it pops. My driver side foot well makes this sound when I rest my foot in the middle of the footwell and move it. It's so odd...
I imagine the Porsche bars are made by Thule. Since you're in the use, if you get a set of the Thule aerobar edge, sized large and x-large, it should work. They look to be the same as the wing bar that the UK folks use. I'm waiting for a set to appear at my local outdoor retailer.
I also experienced the car going from D -> N. Noticed the shift as it happened and put it back into D. 600 miles on the odometer and I also saw that I had a notification that Auto Recuperation is not available just before the shift.
I think you're going to have to clean that off yourself. The dealership cleaning it off will likely end up with micro scratches if it's the shop taking care of it.
In NYC, every storm drain on the belt parkway is a "pot hole". I was driving around in jersey and NYC yesterday in gravel mode on 19" wheels. I cringe every time I see a storm drain, a man hole cover, and uneven asphalt on truck routes.
@RPSRPS was referring to the usage of the my Porsche app to do the route guidance and send that route to the car from the app. That route guidance has never worked for me on an android. Maybe it works on iOS.
