Even if they did update the engine, it would be to better tolerate a lower-viscosity oil without excessive wear. It's the only reason because besides a marginal fuel economy increase there is no advantage to thinner oils.
VW 504 5w30 ok to replace 0w30 ?

Because they are required by the EPA to run whatever oil grade that was used to pass their CAFE test. No exceptions. That's why they will never tell you that it's Ok to run anything but VW508. They can't by EPA rules.
Close, they are not required to use the specific oil but they must aggressively promote the use both in an owner’s manual and in marketing materials. They must also work to guarantee availability of the oil both at the dealership and in the general marketplace. But they are not required to use what’s recommended in the manual or on an under hood sticker.
Yeah, you have assumed I am in the USA haven’t you?
And that the handbook I have read it for a US market model?
Both are wrong
We don’t have CAFE and EPA in the UK so it’s nothing to with that.
You did read the bit where they allow up to 1/2 litre of top up?
Likely due to the rarity of the 508/509 oil away from VW/Audi/Skoda/Seat dealers
No but you do have fuel economy and CO2 emissions standards, first based on EU requirements and now on your own. ACEA Sequences have responded with a maximum HT/HS of 2.6, and are set to decline to <2.6 in three years.
That's creative. At least you're not trying to make it some sort of technical reason.
