Not sure what all the delay from BMW NA for the faulty Vanos bolts replacements is? Most suppliers show them out of stock or NA.
However, Pelican shows them here:

They’re cheap at under $1.00 each. When I replaced mine a few years back, I ordered extras because it’s easy to chow the heads installing them due to the funny angle you need to torx them in. You need a security torx socket to remove the old ones and then an extra long shafted torx to install the replacements.
