So what looked to be a squeak from the dash came from a screw/plastic/metal clip that holds the plastic inside the wheel arch (lower front part of the wheel arch). Pulled the light and pressed on the plastic behind it (basically the outside of the wheel arch) - squeak squeak squeak!

The dealer found it but wanted the car for a few days to track it down. So I sorted it. Just put some grease on the section which was the problem.

The lower arch is held by 8 screws. You just need to turn the wheel to one side depending on what arch you are working on. No need to pull the wheel.

That squeak almost drove me nuts!

 

Started squeaking again! So found the problem now I think. 2 loose screws.
