Rubber trim around the windscreen

Picked out the old one, along with as much gunk as I could get.
New part is push fit...no clips required.
Start at one corner and work down.
Then across but pull the trim reasonably tight....not overly tight though. Otherwise, the second corner won't sit right and you'll need to remove and start again. (Don't ask me how I know :rofl: )
I used car shampoo as a lubricant to insert the new trim. Don't use a lot down the sides because the design of the trim makes it want to pop out. If you chuck in loads of lubricant, it can pop itself back out. (again, don't ask)

Only other thing I'd say is, most importantly, use proper trim removal tools. In my research before starting, I saw posts claiming cracked screens etc.....using proper tools and it's no issue. E85 part number ends in 11, Coupe ends in 21. No idea what the difference is. But I notice that some places, including where I bought it, have the E86 part ending in 11. I bought the part ending in 11. It fits just fine.

From start to finish, including removal to refit after not pulling tight enough, was around an hour.
Appreciate the detail. It sounds to me that the key is getting all the old gunk out first. Is that easy to do? Is it obvious what needs to be removed? As you pick the stuff out, is there a risk you could inadvertently cause a leak somewhere?

There is about 1.5-2 cm of gunk under the glass, that seals it to the car and makes it waterproof. The gunk to be removed is anything that is outside of the glass as well as almost 0.5 cm that is behing the glass. That was the most difficult part on my car as they had squirted the black stuff generously all over the place.

I replaced mine as it was whistling, not because the rubber had gone.

In my case, the gunk was a black sticky adhesive that seemed to be holding the old trim in place. I used my fingers to pick out the worst of itand gave it a rinse out but I didn't spend much time chiselling it out. As PVR says, it may be that the gunk is the sealant. As long as the new one is seated properly, then you don't need to worry about removing the stuff that's stuck in there....it's just unnecessary work.

If it helps at all, I managed to replace the seal without cutting/mucking about with the screen glass gunk/sealant. If any does need removing you need to carefully use a stanley knife but be careful not to score the paint/metal.

Obviously to spite me, the car decided to go and get a cracked windscreen 3 days after I fitted the new seal, so I had to get ANOTHER Seal to be fitted with the new glass. But that's beside the point.

It's a pain in the arse to fit, i recommend if you have access to a heat gun - it's useful as it's much easier to get the rubber to squish and sit in when it's warm. Again from painful experience I'd avoid doing oustide in direct sunlight when it's 30C+, as the rubber gets so hot it burns your hands. Which is also fun, and makes it totally hilarious when three days later, and with the blisters on your hands still a fresh reminder of your efforts, you get a cracked windscreen.... but I digress again...

It is all how the last glass fitter fitted the glass. He obviously put mine too high on the car which caused me all sort of grief with the wind noise as the rubber would sit proud with a gap of about 1 mm or less. Mighty noisy when driving though.

Be in mind gunk does not mean glass black glue/sealant :roll:

When you push the new trim into the space, is it easy to know that it is properly in?
I'm not expecting a satisfying click, given its rubber, but wondering if its easy to tell that its good.

Yes...it'll just sit right. If it's not right, it's obvious

It's around £40-45. Not sure you'd even get a 3rd party one but a genuine one would likely be softer and easier to fit.

Dealer was the cheapest for me, even cheaper than eBay for non OEM ones. They even had it in stock.

That is for sure! When I still had a bit of gunk in the channels, it slid off as quickly as it slid on. The sides were easy for me, it was the top where it kept popping out
