Default New 2015 535i

I have been absent from this forum for some time due to some personal issues. Anyways I went ahead and returned my 2012 535i for a new 2015 535i last Saturday.

It is a 535i non sport
Alpine White
Black Leather Interior
Premium Package
Lighting Package
Driver Assistance Package
Heated Seats


My 535i is plain and simple but I do have one concern though.


I test drove this new one and everything was fine. Did the paperworks and the whole 9 yards before I proceeded to take home my new baby. All of a sudden I noticed that my headlights have a little fog inside! I find that very odd on a brand new vehicle. Service advisor came out and explained that it is "normal" because I have the LED headlights and since they heat up to very high temps that it has a built in ventilation on the headlamp. The ventilation is where the fog and/or moisture can possibly enter the headlamp housing.

Doesn't sound odd to you, but I do not understand WHY they would allow fogging and moisture to enter their headlamps even if ventilation is required.

I thought LED runs cooler than Xenon and Halogen? I would definitely make a note on the next service visit. They may make the same response on the service order, but at least you would have it in writing for any future warranty claim, should it recur after a car wash or rain. Moisture or water coming in contact with any hot internal surface inside the housing cannot not be a good thing. Incidentally, those Adaptive LED headlight units are about 1500.00 USD each.

LEDs tend to reach higher temperature than Xenon. I know because when I first got a brand new IS250 loaner when I took my Lexus in, it had LED headlights. Then one of the porters was explaining to me that the LEDs tend to heat up more than Xenons and he showed me the ventilation system in the Lexus LED headlights. I am unfamiliar with BMW's LEDs but I believe in my 2nd photo that the ventilation are the lines on the side of each Halo. I could be wrong but they look like "vents"

Yes I am more interested in having this issue noted but it does not happen consistently. I don't want them to replace NOW because it requires them removing my front bumper (and I do not want any body part removed yet when my vehicle only has less than 300 miles as we speak) but if it gets worse, I'll have it done in about a year just to observe how it handles both hot and cold temperatures in a one year span.

I wouldn't like that if it was normal.. But to put some ease in your mind.. our brand new to us Mazda CX-9 had the same deal when we took possession and I noted it. It disappeared and never came back.

Of course that was not LED headlighting. My friends new corolla with LED did not have that either...

If it ends up coming back a lot.. I would have serious corrosion concerns in those expensive headlamps!
