It looks as if the side repeater housing the bulb has come loose from the light cover on the wing, what is the easiest way to locate the bulb and its housing ?

take off the wheel arch liner, several multi spline screws.

Cheers Lee. are they torx screws and if so what size ?

Yeah, not multi-splines, Torx 25's.

Cool, can it be done with the wheel on ?

easier off I think, but possible if the wheels still on

Turn wheel hard right, should be enough room to undo a few of the screws and get a hand in.

 

If you want the whole liner off, then wheel off definitely

I just need the liner off enough to get my hand  behind to feed the side repeater housing back to where it should be.

Jacking the car up would give you little more space too . But then might as well take wheel off for 2 more mins haha
