My windshield got replaced in my 930 and I have been dealing with massive leaks and the seal not fitting. (I think it may be the glass even though it came
From Porsche)
I had them put in the URO seal which is bigger and now covers the body but now the trim does not go all the way down and it still leaks.

Finally installing my front glass with the URO seal.
Regarding this bonded seam... is there a preference where it should go, top/bottom?
I've located it in the bottom center. Does it matter?

How old is that seal? I don't recall that seam on my URO windshield seal that I installed 5 years ago.

To answer your question: The seal is formed to fit the windshield, thus the top section is shorter than the bottom section. Don't reverse them.

I bought it 1 year ago. It is one of the "new / redesigned" ones URO batch#11104

I'll pull it off and double check for fit. It was not obvious to me, but maybe I just didn't notice.

But, now I question whether that big chunk of seam is normal. Does anyone else have one of these seals with such a blob?

BTW, I still don't see an obvious top vs bottom.

Ironically I got one like that, but my bonded seam was peeling out a bit and we did not want to use it, and ordered a different one. I reached out to URO, sent them a pic like yours, and they said “That does not look like one of our seals.” I am still talking it through with them. Glad to see yours looks like that too.

Not sure I like the look of that seam?

Our URO seals have that same seam.

I believe it goes on top.

Hi guys, we're currently investigating production run #11104 due to reports of possible excess length/bulging, and an unattractive top seam. Will report back once Engineering completes its review.

We definitely had that on the last one. Purchased from SSF on 04/30/2025

About to install this 11104 and was wondering your out come Mr. Merks???

Status update as of 9/11:

• Confirmed that batches #11104 and #11819 have the unattractive seam.
  
• Most of the seals in #11104 are too long.
  
• We went through several seals from #11819 and found one that was the correct length. Hopefully there are more than we can send to buyers of #11104, though that doesn't solve the ugly seam issue.
  
• We've frozen wholesale sales of batches #11104 and #11819, but there are still units on retailer shelves that will likely need to be scrapped.
