OBDII Blocker

Hi guys, I replaced my W204 with a W117. I'm after a OBDII port blocker. Presumably same blocker fits both models. Any suggestions?

I thought all we're the same size when it comes to OBD2

I had to look up what that even is.

By law the OBD2 ports are universal so they should all fit.

Are you asking for an OBD connector locking cover that prevents unauthorized connection of an OBD scanner?

Yep. The issue is restricted area surrounding port. Attachments I've tried won't fit in this tiny area. There are ribs inside the short side surround.

Maybe an electronic blocker like author-alarm.com offers? Requires a bit of wiring. European device, so don’t know if it’s available in Australia.

Curious, but why do you want a blocker?
