Windshield seal questions

Hey all. Debating replacing my windshield seal. Mine is not cracked or dried out, but it has pulled apart/separated at both top corners and I think the center section has shrunk so I doubt that reconnecting it is realistic (see pics).

However, I'm a little confused as to what to order. I plan to get the part from FCP (lifetime warranty) but they list two part numbers (info from FCP and GAP)

51318172745 only for cars with protective windshield S357A

51318159784 not for cars with protective windshield S357A


I'm honestly not sure if my car has the protective windshield/glazing they're talking about. '03 model year. Any info appreciated.

I replaced mine last summer with part # 51318159784. I believe I read somewhere on the forum that the protective windshield is armored.

Protective glass is much thicker glass with extra poly film layers. Super rare, and if you had it, it would be shown as an option when you decode your VIN.

Small update on this...

-Ordered the part (yay car parts!)
-Pulled old molding off. Came off no problem.
-Put new molding on. Wait no, it wouldn't go on. Just wouldn't pop in the way all the DIY's and videos describe.
-While pushing and fighting with the molding, I found out that the left side of windshield is loose! I can move it with my fingers.

End result - called glass guy, he took one look and confirmed my suspicion that this is a replacement windshield. It'll have to come out to put the molding on, and to properly re-seal the glass. I have the best luck!

He's recommending that I go with universal molding instead of the OEM part; he feels it will last longer. Anyone have an opinion on that? He showed it to me and it would look just fine.

I replaced my front and rear molding on my LeMans M5 a little over a month ago with original glass and it a fairly simple process. Bummer that your windshield has been replaced before. Make sure the windshield is reinstalled properly. I would still recommend using the OE part instead of the universal molding.

Yeah, well, now the work will be warrantied by a professional installer, so there's that... I also had a (rare for me) "what the hell" moment - the price difference between remove/replace and a new windshield is small enough that I'm just going for a new windshield altogether. My car had a lot of highway miles from the previous owner, with tiny rock chips in the front windshield to match.

Sorry to hear of the complications. Did my rear gasket a few years back, pretty straightforward. Sometimes the old rubber remains in the slot, and that complicates things. Window Trim Replacement on the BMW E39 - chrisparente.com

Note - the gasket is not the windshield seal, is not what keeps water out.

Helpful. Iím replacing this soon. Good to know no windshield removal needed. Screw those money hungry dealerships.

Not meant to steal your post and spotlight but rather to get an advice and perspective. I have this issue on my 2000 M5 where some windshield plastic trim (or molding, whatever it's called I'm not familiar with correct nomenclature) is lose and popping off (mainly passenger side), see picture. Local BMW dealer (Crevier BMW in Southern CA, greedy bastards) told me that it's a $400 price to replace the windshield trim, and that most likely windshield will have to be replaced as well due to high chance of breaking it while replacing the trim. Overall I'll have to pay around $2400 for new windshield and windshield trim. Hell no I'm paying that much! A friend of mine working at another BMW dealer showed me their price book; there that plastic trim costs $43 and he said he replaced it like 15 times on regular E39s sedans and wagons with no issues and no glass breaking. Is it possible to safely replace this plastic windshield trim and how hard would that be? Thanks.

No, the glass does not need to come out and this is very doable job. Amazing dealers are still out there saying that, and then saying they will probably break the glass!? Please see link to blog post with pictures in my previous comment.



And FWIW, your trim doesn't look that bad - sure you can't just push back in?
