Is this the black plastic that sits under the windscreen?

I think some places refer to them as a plenum panel as that's what I found mine under.

I got a new, non-genuine part for around 170 plus postage (link below) as the plastic itself gets brittle and cracks easily so didn't get he 2nd hand option and avoided genuine due to price mark up.

Here is the old panel:


And here is the new:


From memory, the steps were:
1. Remove bonnet
2. Remove wipers
3. Remove old panel (cracked & snapped so unsure if you'll need to undo more)
4. Insert new panel reusing old rubber and fixings

Just be aware that there is no air intake holes where the foam goes. Or if you longer have any foam, the place where the steel clips are that used to hold the inlet filter foam. LOL

The non-genuine part doesn't have air holes to allow for additional ventilation - nothing a dremel can't solve if you truly desire it.

I don't feel like it has changed anything for me though.

The picture below shows a solid piece of plastic if you wanted to compare to your current one



Where my finger is positioned is the surface that should have holes through it for ventilation

oh ok. thanks.

Technically, you don't need to remove the bonnet.
It can be a PITA if you're on your own.

I just undid the bonnet bolts from only the one side, and let it rest back on the hinge while I did other stuff, shuffled the plenum trim around a bit, then back at the loose bonnet hinge end again and lifted the bonnet with one hand, and slid the plastic trim out while it allowed access.
Fitment was similarly easy.

I changed my 'more broken' one, with a less broken one, which I stuck back together with Epoxy and two metal strips underneath(epoxied) to give it some strength. Doesn't look new, as you can see the seam where the epoxy has been used .. but I could sand it back to give it a 'new-ish' finish.
The only issue with using epoxy is the setting time. The trim is curved, so doesn't just sit. Had to make a cradle using styrene blocks and pieces so that the trim sat in it's normal position.
