I also hope the nightmare is over. It's been two and a half weeks since mine got the software updates, apart from these two issues the car has been behaving as it should and I am very happy with it (after fourteen months ownership)
Two days after the update high engine oil level message appeared, I checked the oil level when the engine was cold and level was above the max indicator (car was serviced mid last December) Contacted the dealer and it was corrected physically and with software within two hours of phone call. I have to assume the software update detected the high oil level better / different than the previous and yes it shouldn't have been high in the first place.

Second issue, just a few days ago AC wouldn't kick in - warm day and everything was functioning, just no cold air, all was ok after parking, shopping and returning to car.
Finally, I know I brought this up before and am just wondering if it is now on all users updated IS AC controls

Why did VW deem it necessary to have SYNC appear on the passenger side temperature display? SYNC in this example has been choosen and is indicated / highlighted as shown in the photo. To me it looks a bit strange / unnecessary (SYNC shown twice) and like an error someone made when updating the IS software code or is this only on my car!
