Yea, my oven isn't the best, not do I trust myself enough to bake them. Anyone near Ventura county want to help me? Experience preferred :D

My '01's came apart really easy.

10 minutes at 200 degrees.

Get some gloves with the rubber bumps on the palms.

Best of luck!

Yeah, I've done my twice. Not to hard. I did 250 for 8 minutes. I recommend getting some more glue to use when reinstalling them. You can get it at the retrofit source.

I just went through this on my car... only to find out it won't work since I have a 2003 car and they used an epoxy to bond the lens on (not something any of the how-tos I've read mentioned). Good thing I didn't melt my headlights in the oven. Did manage to tear up the housing plastic trying to pry though...

Good luck! I might be buying new lights now.

I would just make sure that the headlight was never replaced at any point like one of mine was. I was forced to spend 20+ hours dremeling the second one open after finishing the first one and am likely just going to buy new headlights because I made some errors.

AJ, I did mine as you've seen them in person. They're not 100% perfect, but I'd definitely get some butyl from TRS before doing this.

Its really easy to do this yourself, I have done it before and the hardest part was getting over the mental block of putting my $1000 headlights in an oven. If your oven isnt super reliable, err on the side of caution and run the temperature lower. Remove after 10 minutes, if they need more time, put them back in. If after another 5-10 minutes they wont come apart, raise the temperature a bit.

On the back of the headlights, near the lower mounting tab on the "outside" of the headlight there is a little circle... it has 1-12 around the outside and two numbers with an arrow in the middle. The arrow points at the production month of the lights, the two numbers represent the year. Mine say "02" in the center with an arrow pointing at 9, so the produciton date is 9/02. I have read that anything after 7/02 is RTV and can not be baked open, but mine are euro and 9/02 and are butyl.

A secondary test is to unscrew one of the torx screws by the side reflector. If the screw comes out with some black silicone-like goop on it that is sort of elastic, they can be baked open. If the screw comes out dry or with some black "hard" adhesive, it can not be baked open.

This is the most specific post I've found regarding production dates. Tagging for later.

I was told clear as day any E39 lights produced after 7/02 used RTV and could not be baked open. My euro set is 9/02 and is able to be baked, so I am not sure the reliability of that information. Unfortunately the production info is the same from pre-facelift to the end of the E39 production run so realoem isnt helping to determine when the cutoff was for RTV.

The best bet if someone has late-2002 lights and wants to see if they can be baked is to go by the screw as that is a way to tell directly what type of adhesive is used.

Here is my bit of advise, I have done this twice with success.

Empty your oven, leave just a rack in the middle. (I used a nice soft silicone cookie sheet to protect the light from hot pressure points on the metal rack)
Set your temperature to 210. Wait for it to reach that temperature.
Once 210 is reached, turn off the oven!
Put lights in, let it hang out for 5-10 minutes.
Pry open light, if you need to add more heat (which I did) get the oven back up to 210, turn it off, then repeat.

My reasoning is that the (my) oven will put out more heat than 210F to get the oven up to temp. Since the lights are mostly black, I don't want them soaking in all that IR and potentially overheating or starting to warp. Nor do I want the oven to kick back on while the lights are in there to maintain temp. My oven is stupid - it doesn't just give 10% effort if it needs a few more degrees warmer - it is either 100% or 0%!

Am I over cautious? I haven't had to replace a headlight yet..

any worries of damaging adjusters while pulling them apart?

Yeah, you will most likely break them. Order some new ones for like $22 before doing this. Don't ask me how I know.

Yup, the date stamp is right here and looks like this... second pic has vent tube off to let me photo the date stamp

I think OEM plastic replacements are that cheap. You may as well upgrade to the more expensive aluminum units while in there though. They are <$100 from CA Automotive last I checked

I bought these, they worked fine. Matter fact, I'm about to do a friend's headlights soon, he just ordered some new projectors.

These are the Aluminum ones, they weren't worth it for me. The plastic ones are probably gonna break in 5-7 years, I'll let the next guy worry about them, or I'll just do it myself! :D
