BMW E39 Rear Windshield Gasket Replacement DIY 

Thanks! Now it's time to get an M5 ;)

Thanks for the kind feedback!!

This gasket could still be responsible for this. What I mean is, this is not the sealing gasket to seal the rear glass. If yours is in poor condition, it's cheap and easy enough to replace to try to get a dry trunk. Check the gaskets around the trunk lid to, they may be compromised.

@@E39Source I have condensation inside my rear windshield and on the interior of the car; that would be due to the sealing gasket?

@@yovarniyearwood It could be, but that would mean the butyl tape holding your glass is compromised as well.

@@E39Source got it, appreciate the fast response! So glad I found your video before I went out and replaced this seal lol.

You'll want to exchange it for the right one. The security glass is thicker, and so is the gasket for vehicles with that glass. It won't fit right with the standard rear windshield. The new gasket should last another decade or two, though extreme heat and a lot of sun exposure will degrade it more quickly. If there's wind noise, it's because there is too much butyl tape sticking out from around the glass preventing the seal from fitting snugly down in the channel.

@@E39Source thanks so much for the quick reply!

I'm not sure what you're referring to.

You want this one: bit.ly/2FHb6c4 which appears to be in stock.

@@E39Source Ryan and the team are phenomenal!... If you have a question, concerns,doubt, etcetera...They always come through!... just ordered the part!

back ordered on ecs as well.

@@PursuitMode2011 At that point, patience!

@@E39Source FOUND NEW PART NUMBER 51318159785 BMW E39 REAR WINDOW MOULDING and BMW has it in stock.

That all depends on your preferences and budget! I will always recommend an M5, which only came as manual, but each model has its pros and cons honestly.

@@E39Source Thank you for your attention, but I'm looking for this bike that gives me pleasure in driving and not spending a lot of fuel

If you want diesel than get 3.0 not less

I struggled differentiating which one to get, but at the end of the day, these fit perfectly! I'd recommend the part number that I bought and listed above.

@@E39Source How thick is the glass on your rear window?

@@fabiandee8178 The vast majority of E39s use the standard glass, part numbers in description. If the vehicle is equipped with the security glass, you'll want the thicker seals.

@@E39Source Yeah I know, my vehicle was ordered with double glazing side and rear but I think they only installed it on the side windows, so I'm trying to gauge how thick your glass is to accommodate the seal for the security glass to compare it with my own window thickness to determine what type of rear window I actually have.

@@fabiandee8178 I unfortunately don't have a way to measure the thickness of the glass, but I would assume if any windows are the thick security glass, then all of them would be.

No, parts are different.

Thank you!

Not much to think of, It's a very good car.

Any tips or tricks about it?

About $45 for the upper gasket and $30 for the lower one.

@@E39Source i also have to replace that buitl tape in my door seals, any idea where can we get that cheap

@@asmircar1 Butyl tape should be butyl tape, assuming the dimensions are the same. You can check Amazon or an auto parts store like Auto zone for that I would imagine.
