    Got inside the Light !!!!

    Well, well, well........

    I finally found and somewhat destructively opened a Z8 headlight unit today. The inside of the Polycarbonate is actually coated with some sort of solution. If I clean it with inert alcohol it becomes very sticky and crystalises. This coating is what is going foggy, not the lens and it certainly doesn't look like a result of condensation build up. Never seen condensation that became sticky!!

    I feel sure BMW know all about this problem.....maybe an email to the manufacturer Valeo, will shed some light. The degree of fogging is being caused by the thickness of the coating hence the reason also it looks patchy when seen close up



    Regards

    very interesting. The coating must be an antireflective coating. It probably needs to be polished off rather than cleaned off. I wonder where you could get a new AR coating for something that large. Could look really cool to have a high quality AR coating put on--certainly looks great for watches.

    Wow. Three years since the last post and nothing since on these headlights. It doesn't sound like disassembling them is a viable option. I'm curios if Minimarvel attempted to clean the headlight with anything else before trying the alcohol. Water? Soap and water? Window cleaner? Polish? What if one was to just remove all of that coating with something (polish?) and polish them until perfectly clean and clear polycarbonate? Once taken apart, is reassembly possible? Would it last? I'm still amazed with the amount of dead headlights and spares out there that more attempts have not been made on this project. I look after five of these cars. Four are virtually brand new and never driven. One is used somewhat regularly and shows around 9,000 miles since new. Out of ten potential foggy headlamps, seven of them are. The three that are not are all on the drivers side. Probably just coincidence. Also, among the members who did replace their headlamps, how many replacements have proceeded to fog over and how long did it take?

    Gar,

    I found in the end that the inside of the headlights are coated with a form of gel. It is the gel that goes foggy. There is no way to disassemble the headlight unit to repair/clean or remove the coating. In my opinion a design fault.
    If it is of any use, I have one new (clear) Drivers side headlight unit for sale if anyone needs one....

    Regards

    Curiously the cars in Europe, which have the same headlamp assembly process, seem far less prone to this issue, but by now most of us here in the US have suffered it. I replaced my passenger side lamp about three years ago and so far both are still good. As far as I am aware the replacement units have not been fogging as badly, but since the mirrors will have you calling Bill Stewart I suggest you also discuss this with him as it is a very well documented issue.

    Oddly enough I also have the tail light moisture on mine, but it isn't nearly as noticeable or annoying as the headlamps.

    Hi,

    About to finalize a deal on a Z8 but made it contingent on headlights - they are lightly fogged. Andrew responded and mentioned replacement is the only option. Does anyone know if I would have to bite the bullet and buy from BMW, or are there places online that are reputable that carry the OEM part?

    If I seal the deal... will post details!

    Thx

    Hi,

    Sometimes you see the headlights offered at Ebay. Personally I would buy them straight from BMW ...at least you know they came out of the BMW stock and you have a 2 years warranty.

    In Europe they cost 900 euro each. Probably one hour labor so it will be cheaper than you expect

    I had them installed on one car last week, and the installation cost was virtually free as I was having the PP installed at the same time. Headlight removal one of the PP install steps, so it wasn't extra to install fresh ones on the reassembly.
    Doing the same to another one this week.

    If anyone has no use for the fogged headlights being replaced, I could use a set for experimentation purposes. I will gladly pay shipping to Switzerland.

    Does anyone have an updated contact information for Bill Stewart? My lights are fogged and as usual I got the run of the mill crap from NA. Take it to the dealer, kneel to Zod, etc....
    I was hoping to contact Bill directly before I waste more time with dealerships.

    thanks

    Just checking to see if there is any new development to fogging headlights? Is buying from BMW still the best option?

    I am on my second set of lamp enclosures (replaced in about 2003) and fog on the drivers side has been slowly building for a few years, which will put me on enclosure #3 on that side.

    My question is; Has anyone been made aware that the new enclosures are any more resistant to fogging that past units? In simple terms, are the newest one any better?

    Would i be correct in saying there is no solution. Replacing today will not be a fix. If that is the case is there anything we could do...any suggestions?

    Yep, and that is about all you can do now. Pay your money and take the new units from BMW. At some point you will not be able to buy them any more as evidenced with other cars I own.....some of them only 20 years old...!BMW are not obligated to continue to supply.It seems however, that is stored indoors they do not degrade, so maybe live with it until you need to sell the car for the incredible prices being asked.

    Fogging Headlights

    I was told by BMW last October that there were no plans to change the design of the Z8 Headlights at this time. I believe BMW made a commitment to make parts for the Z8's for 50 years. I had a 2003 Z8 with 818 miles on it and had the right fogging headlight replaced under warranty in 2006. I just replaced last October the headlights in my 2k mile Z8 which stays undercover in a garage with no windows. I have heard of people ordering new lights that were starting to fog when they open the box. I think the trick is to look at the production date on the back of the new headlights and make sure they haven't been sitting on a shelf in a warehouse for the last 10 years. If you order new lights from BMW you should state when ordering that you want lights that were produced within the last few years. Most BMW Parts Dept's will understand and try to find you newer produced replacements.

    i tried to reach Bill to no avail. MIne has always been kept indoors and both are fogged, the passenger worse than the driver side. Please let me know if anyone has suggestions.

    I wonder if a solution may be to use some kind of a tinted wrap to cover the headlights and hides the fogging. On a black car, it may actually blend in nicely. For those of us that drive during the day mostly, the loss of brightness will be less of an issue.

    Unfortunately Bill Stuart passed away about a year ago. Please see the thread below.

    There is a german member of the Z8 club, who claims that he can clean the headlamps. The pictures look convincing!

    Wow!

    Any details? Did he have to bake in an oven and separate the pieces and reassemble everything?

    That would be great.

    Or should I ask; Is this a service he is offering to others and therefore wishes to keep the information proprietary?

    He offered this service on the club forum of the Z8 club. I sent him an email.

    Update: He disassemble's, cleans and assembles the headlamp again.

    I've replaced mine and they have fogged again. I wonder if there is a way to protect against that. Otherwise this becomes an expensive and time consuming process.On the other hand, if it makes sense, with the numbers of affected units, it might be time to consider a group service buy.
