Part of the problem is counterfeit parts I believe. Even when you think you are buying genuine Denso, often they are not. There are many cases of this reported all over the internet (https://www.google.co.uk/search?q=suction+control+valve+denso+fake) and I recently fell foul to it myself.
My below photograph shows a genuine Denso VCV box on the left and a fake on the right.

I was having typical VCV lumpy running issues so ordered and fitted what I thought was a genuine Denso VCV only to find the high pressure relearn would not complete and the vehicle ran like sh*te.

Sourced a genuine real Denso VCV which cured the issues instantly.

Handy that the fake one is identified by a pencilled "F" on the label, I would have thought you'd have spotted that! Rolling with laughter

However, does it mean “Fake” or something else?

What happens if you scan the QR codes on the labels? They seem to be the only thing of substance which differs, and I wonder what the fake's code contains.
