      LOL I did the adjusters as well from the rear. Did you polish the lenses if so what kit did you use? I have the 3M disc but haven't gotten brave because I'm sure I'm gonna tear them up :D

      "You had one chance to get it right Rock! "

      Vapor barriers are a pain I did them in my 2003 .. Take it slow the plastic trim tools are a good idea .. I only had to do it once.. I removed the original glue and used RTV-ultra black, painters tape, and duct tape to hold it in place, then removed all the extra tape once the ultra black cured. Seems to have worked no more wet floor.
      You will tear them up, that's the point. I used this 3M kit...

      ...in combination with leftover discs I had from this 3M kit.

      The discs are the same size but the "by hand" kit includes a 1000 grit wet sanding disc in addition to the others. I used the drill first for each step, then fine tuned it by hand before moving to the next step. The results are not perfect by any means, but they look much better. Used Klasse sealant on both when I was done to protect the new surface. Ideally I'd like to do a projector retrofit and install Euro lenses but that is a pretty low priority for me right now.

      I did vapor barriers on an '02 530i I had. Still have plenty of butyl tape leftover from that. Hoping to hear about any tricks people have to prevent the barriers from separating from the butyl tape so quickly (along the bottom where it gets wet). I think it's all about making sure water doesn't get trapped along the bottom edge.

      I used a combination of black duct tape and painters tape to help seal it . Left the duct tape in to ensure firm contact with the butyl

      I forgot all M5s came with xenons.

      Replacing the adjusters should not be too hard. I think it is actually easier to do on the pre-facelift cars. I have done it on the facelift lights which you have to use an oven or a heat gun to open up. The I think the pre facelift ones just unscrew or unclip the assembly.

      I agree with Sailor24 your lens look pretty good. If I were you I think I would just give them a quick polish or leave them as they are. If you do decide to polish them you might just be able to skip to the buffing step and skip the sandpaper steps. Fyi I used this 3m kit and I really liked it. There might be some better kits out there now. If you do use that kit (or a other kit with sandpaper) I would maybe just skip to the foam pad and the polishing compound step and see how you like it. It does not look like you really need the sandpaper. fyi if you/any of your friends do paint correction on cars with buffers or DA polishers you/they can use some compound and pads to buff your lens'. If that last bit did not make sense then just ignore it.

      If you personally feel you need crystal clear lens' and don't want to bother with polishing them then you could put on some new lens' while you are replacing the adjusters. I think these smoked ones or these clear ones would work (I think Schmiedmann is in Denmark). There are probably some good UK sources too I just personally don't know any. But unless your lens' look much worse in person I would put that lens money towards something else.

      As far fixing your lights vs new lights goes in terms of lighting performance they should be the same unless there was a difference in pre facelift xenon vs. facelift xenon light output. But if there were any differences I would think they would not be noticeable (I'll let someone more knowledgeable correct me if I am wrong). The only other performance difference would be if umnitza is upgrading you to bi-xenon projectors, which would give you an increase in high beam performance. If I were you I would replace the broken adjusters reaim the lights and see how you like it. Xenons give really good light output it was the e39 halogens lights that were terrible. The Umnitza option is basically just paying a lot more money for the facelift look and no real performance advantage vs fixing your lights for cheap. Spending that money on new facelift lights is not necessarily a bad thing, but depending on your budget your could probably spend that money on something else.

      You mentioned you got new bulbs I am assuming you bought new xenon bulbs as the two that I mentioned are halogens and would not be helpful for your low beams. Although I think the pre facelift cars used H7s for the high beams too, but I am not sure.

      Aiming
      Check out the attached pdf for headlight aiming it may be helpful. It sounds very technical, but honestly it is not that difficult. I have done it on the facelift lights and it was pretty easy. You just need a vertical wall, level ground, some painters tape, and maybe a blanket (to cover up one headlight to make it easier to concentrate on one headlight at a time).

      :cheers::cheers:
      Good job man. I used 3M 39008 Headlight Lens Restoration System to polish and used 3M 39010 Polish and Protector to protect the M5 headlights last summer, but the headlights didn't turn out as good as yours. And the headlights got hazed in the inside maybe because I applied too much heat to certain areas.


      They look pretty good in the picture! :lightbulb:

      Yeah, possibly the heat caused distortion. But sometimes a haze develops on the insides anyways, it happened on my fiancé's E60. I had to cut an access hole to get in there to clean it out. Can't split the lenses on the E60 lights...

      The lenses on my car's headlights are cloudy and a bit yellowed so my first official project on my new car will be to restore the headlights this weekend. Has anyone used this 3M kit?

      Amazon.com: 3M Headlight Lens Restoration System: Automotive

      The reviews I've found are very positive. Just wondering if anyone here has used it. If there is a better solution, I'm all ears.

      Thanks
      Todd
