After nearly 2 years of waiting for the screen wash to get there I thought I'd have a look today.

I don't have one fitted, one on order problem solved there.

Looks like someone has been there before as there is dirty brown staining on the inside of the trim, some trim clips missing and 2 of the plastic tangs bent flat. Which brings me to my question what are the metal clip thingy things called?
They sit in the slots of the tailgate and the trim piece tangs push into them as I need 2, because now I've disturbed things and put bits straight I now have a rattle. Trim will be coming off until I get new clips.

I happened to buy these a few weeks ago and they arrived the other day, I'm not even sure if they're the right size, I haven't had time to check but I suspect they're a little small for the trim you're removing, I'll have a look later if I get a chance but Dan at Duckworth should be able to sort you out.

BTW, when you say you don't have a rear screen washer fitted, has someone removed the parts?

I'm pretty sure all l322's were fitted, there's loads of threads about them not working, I've replaced the seal and NRV on mine.

No NRV fitted, washer works fine after a minute of holding the rear wash leaver down, just needs a NRV to stop it draining back to the front.

Thanks for the link but as you suspect they are not the right things.
