Is there anyway how i can spot the difference between both versions of breather?
I have got one from a 2009 model (according to the seller), bought from a scrap yard that parted out a Tenere. But on the part itself it says manufacturig date 12-07 and partnumber 11D-E5371-00.

If i look at the fiche i cant make it out either, the part numbers don't match up:

it says 11DE53711000 replaced 11DE53711200. But mine doesn't match either, although it's close to the first one
