Moisture in front head lights

Hi Guys dont know if this is a problem or not, but usually in passed vehicles moisture build up means signs of a broken seal.
Its Christmas time and decided to give myself a gift and took my new Edition 1 out of storage for a couple of days (also we are having some nice weather in Wpg Mb.).
When i pulled back into the garage and did a walk around I noticed fogging in both front head lights. has anyone noticed anything similar?
If this is the norm no problem.. but wanted some input from other owners before I take a trip to the dealer.

I have the Halogen lights but I would not consider water in the headlights normal.

In most modern headlights, there is usually a tube built into the headlights that assists in evaporating any moisture from inside the assembly. If this becomes obstructed, this is usually what presents unfortunately.

This is one of the RARE times I would say, go to the Stealership. They will take care of it for you, especially as an AMG-buyer.

Agreed. the last thing you want is to have the moisture affect the bi-xenon bulb as replacing those can be expensive (~$250-$300 ea.).

Fogged headlights

Found out from a guy in the UK that he remembered reading about something like what I had in the owners manual. He was correct. States that this is normal in the right weather conditions.

Many users in the new C class forum are experiencing the same thing....

Manual does in fact state that this is normal but I don't really see how it can be

In my 2014 CLS with all LED headlamps, manual says some condensation can be expected in the lamp housing under certain conditions but it should self correct over time.

My GLA250 had Halogen headlights, which didn't have this condensation problem.

Then I switched the OEM DRL/High Beam H15 Halogen bubs with H15 80W LEDs that equipped with projectors.... It does looks much better than the OEM tiny yellowish DRL. Yet after a snow shower the very area on the headlight in front of the newly installed LEDs developed condensation....

The condensation went away after parking the car in Garage for a night. But next day I drive it outside and the condensation come back again......

I'm exhausted of these car brands claiming that it is NORMAL. It's total and COMPLETE LIES. How do I know?

Because you can 'mod' your headlights to stop doing this. You can bake them and re-seal, or you can add an additional breather tube. Dig around the Audi forums, you can find a few who have done this to their S4's and S6's.

I baked and re-sealed the headlights on my Audi, and it never happened again for the last 2 years I owned it.
