I had this issue with my previous '19 GLA45. The VIN either wasn't associated with any useful information in the online VIN decoder websites, or the VIN wasn't found at all (I get an error saying the vehicle is too old or too new, but neither are obviously the case). Same thing with this one I got a few months ago...

I was able to get the options list from a dealer for the last one, but haven't managed to get one for the new car yet.

Is this common or what makes my two examples special?

 

The 19 year has some crossover issues, that may contribute.

try both vins at rock auto
and FCP euro both big and with separate supply chains
