Just checked my car it too was build week 40,I’m still on 1664 and have had the steering wheel replaced.
I now have zero issues other than the nav not available in the dash,dealer has agreed my first 2 services for free to shut me up,I decided to accept as I figure sooner or later it will be possible to hack the nav anyway.
When I spoke to the tech at the Vw garage,he said he found it easier to solve problems by updating individual software items rather than the whole lot,hence it staying at 1664,he said when he had previously did an update of everything it solved problems but added new ones .
