I recently tried to take a headlight cluster out but when I got to the last bit after taking grill off and three bolts it would not come out it seemed to be stuck at the bottom on the body. is there extra catches there or something can anyone help please?

 

Nope. Just pull very hard.

After the three bolts it is simply a couple of ball joint clips holding the head light in place.

Plenty of good picture guides on google if you need a bit more detail.

 

There are two ball ended pins on the back of the unit that lock into plastic clips located in the wing and they are a tight fit, as other reply said it requires a good tug to get them out.

I found pushing from the back of the unit helps too.

I would also suggest removing the two plastic clips on the top of the bumper too as this gives a little flex in the bumper when removing the unit and prevents the white plastic arm getting snapped off (Seen a few people do that)

Hope that helps.
