I think the answer is M8-1 or 5/16"-24 thread (universal)

On my e53, I was able to use valve caps from the wheels I've assumed the threads were the same and my kit came with a fitting that worked

I'll try removing the valve core, and also try running a 5/16"-24 tap into the M8-1 brass fitting, that nearly fits (it might just need thread cleaning, or the Schrader valve exterior might, too). From what I've read today, some manufacturers regard M8 and 5/16" as interchangeable, so I'll see how close they really are. And, I found a thread regarding the mystery surrounding the BMW Schrader valve adapter size https://xoutpost.com/bmw-sav-forums/...test-port.html.
I found it, and a reference to FCPEuro's fuel tester description for the CTA fuel pressure tester, which says it will work on BMWs "universally", not listing specific models, and the size of the mystery adapter as 5/16"x.308 (or slightly tighter than 5/16"-24).
