Anyone know what bit fits this bolt head
 

The bolt on the driver side hinge of my passat 2014 is loose and I need to tighten it but I can't find correct bit that fits it. I've attached an image of it here.

I tried a 40 and 45 star bit but neither fits. Any idea or suggestions where I might find correct bit for this?

You need a Torx drive the correct size, I couldn't tell you the exact size without looking at mine.
