Both should work! The 2 valve units seem to be common replacements.

Subject: Blue pressure cap, 1 valve or 2?

2.1 wbx. Cap that's on there now has one valve in the center. I picked up a
spare from a local mechanic and it has two. Anyone know if both are good?

No part number but 'made in Germany'.  Thanks!
