That's great to get a report from a high mileage user.
I've clocked up 16,000 miles in the year I've had mine, I echo your comments on the very useful BHP

But I have still averaged 82mpg (UK) because most of my daily commute is on battery with only occasional long trips knocking the mpg down.
Pity you can't get Audi Connect working, call me a soft southerner but I do like to chill/warm my car up. I also had that on my previous Chevy Volt.
No problems with the local Basingstoke Audi service centre, only one service so far though. I'll report any problems as they arise.
I did not know/notice that the fog lights switch off at speed. Mine has "all weather" fog lights, maybe they are different?
I'm yet to drive on snow. The Volt was very good in snow apart from the low ground clearance.
Keep the reports coming, they will benefit the whole group even though we all use our e-trons differently.
