Change in vehicle VIN number recognition

I'm asking about....

ISO 3779 is the world-wide standard, you can download it here; I recall having read of a forthcoming  amendment, but that shouldn't affect current registrations.

Update:   

We might be trapped in a "eredetvizsga" procedure which is intended to check the origin of the vehicle BUT it seems like this is only initiated when there's a buying and selling going on.   This is not what is happening, it's just the routine roadworthiness test.  It's not clear why we've been selected for this process.

The ISO 3779 is not of use here as that's from 2009.  Thanks for the thought.

There was a 2019 EU directive on Consumer Protection, which must have come into force around 2022.   

Like most EU countries, an "MoT" (roadworthiness test) lasts 2 years.  I can only assume, we passed the previous test before it came into force.  And so we've been driving around doing all the usual things and we've been caught out in 2024 in a routine audit.

There is a VIN plate on the car riveted to the body under the bonnet (hood) but it's heavily corroded and pretty much unreadable.   They can read it if they have a proper test kit. I've never tried to clean it up for fear of damaging it further.   

But then there's the VIN visible through the drivers side windscreen.   In most cars, you can see the VIN through the window or via a lift up flap under the passenger front seat.

It's not like anything else changed.  And they know it anyway from before as they have historical paperwork for sure.  I am not sure how one would get an official replacement VIN plate to match up.  I suppose I could just have one made and rivet it on.
