Ok here's a weird one. After fitting the half jobbie, I started getting alot of wind noise coming from my sunroof. I thought it couldn't be the smaller bee sting, but it go so bad I was ready to gouge my eyes out.
So I fitted the original bee sting back and the wind noise has gone. WTF!
I really don't know how this could be the cause of the wind noise. Maybe I should test a bit more.
