Probably condensation happens because of water or moisture entering into the headlamps. If you observe moisture, which recurs even if you do not run the vehicle through a car wash or heavy rain, it can possibly mean that there is a leak in the seal between the headlamp cover and its housing.

In such a case, the best solution is to replace the whole unit.

I don't know about skoda. But does the headlight have dust cover ? If yes remove it in the afternoon after driving the car if possible (engine is hot) all the vapour inside will evaporate and then check at night.

My verna's headlight got water inside while washing and it. Didn't go away for days , removed the dust cover and within 3, hours of driving the water evaporated

Worth a try.
You are talking about car cover right or is dust cover something else? I did drove it during the afternoon in summers and it was parked without cover for many many hours in the afternoon but same result.

Sealed in the sense , even the plastic wrapper above the case isn't removed or ?

You can escalate to Skoda India
Yes it was plastic wrapped. So, here's what happened in short, I told about this to the dealer>> He laughed saying that I should get more knowledge as in how to use headlights>> looped in a Skoda India guy who instructed them to fix it>> As per the dealer they installed "new" headlights>> The issue was still there, I pressed him he said the headlights were swapped from a demo car>> Sent hundreds of mail to Skoda India, they sent a guy to inspect the car and told the dealer to install "new" headlights>> The guy inspected the car and said that its normal, meanwhile out of the new headlights, one headlight was for my car's vin and the other one from the dealer's old stock which was manufactured in 2016>> Again sent a mail to them they said that the issue is normal, case closed and they won't change headlights as they did it for me as a favor.

As per that link the moisture occurs due to change in weather or difference in temperature and nowhere they have mentioned anything about the water.

I was also thinking that say there was water present somewhere inside the engine or in some other part, then it should have been evaporated by now after all these months. Don't you think?

I have experienced condensation problem in my previous car only during rain or after a water wash and the condensation goes off once the area is dried up. Even I have water washed my present car (2 months old) few times but did not notice any such condensation.

It is something strange happening, which even your service centre cannot properly diagnose it and rectify the problem?

There's a cover behind the headlight of every car. Open the hood and check behind the headlights. Post a photo if you can.

Those guys are themselves the biggest looters and cheaters. To tackle the issues myself I am washing using ONR since the past many many months now and not using the proper water wash to make sure not even a bit of water drop goes inside.

I think the links posted by @allhyundaicars makes sense to some extent. But still few questions remain-

a. Check the manual page, it says that any mist formed will go away when the headlights are turned on but in my case it forms after the headlights are turned on and that too in any weather condition/irrespective of the temperature. Even this link point number 5 says the same https://www.carlightblog.com/2014/06/24/fogging-the-ultimate-guide/ So, why is it happening exactly the opposite in my case?

b. Why is this condensation is not happening in any other Skoda and other VW brand cars which have the same headlights?

c. If the cause of the moisture is say water, then don't you think that it should have been evaporated after this much time?

d. Since the headlight is one complete unit and has been replaced, although the first time they replaced it with the demo car’s headlights and for the second time they did install a two year one. As a last resort senior members from other forums have told me to open it up and dry it or use silica gel sachets. What is the need of opening this unit if it was replaced? The moisture seems to be coming from somewhere else.

@bhvm need your inputs here too my dear.

The headlight comes as a complete unit. It is just attached in the main machine or the concerned part and to remove it the front bumper needs to be removed first. The dust cover would be different with all replaced headlights right?

Im here since day 1, Silently watching the thread.
Since we have already exhausted regular Probing to be done at home (Dust caps etc), I was waiting for some fresh perspective by other members.

I guess the only option remains now is to approach a good lawyer. And battle out in Consumer forum.

Nah , consumer forum just will take time.

Plan B-
Get in written statement from ASS/Dealer , - "If at all headlamp case colour fadens in say 5 years (Warranty period) , they will replace entire unit free of cost "
2. "If at all anything happens (Short Circuit)- Dealership should take full clause

If they don't agree to this , just demand that you will go for case.

If at all this is normal with all cars, as dealership agrees to customer's demands, no fuss for you as well as them.

Try these or did you already?

1. In the night, start the engine but don't turn ON headlights or DRLs. Keep the engine running for several mins and see if condensation (Use torch to check) happens.

2. In the night, open the bonnet, start the engine and turn ON headlights/DRLs. Keep the engine running for several mins and see if condensation happens.

3. In the night, use hair dryer in front of headlights and see if condensation (Use torch to check) happens. BUT DON'T OVERHEAT THE HEADLIGHTS. Engine and headlights should be OFF.

4. In the night when the headlights already have condensation, use hair dryer in front of headlights and see if condensation (Use torch to check) goes away. BUT DON'T OVERHEAT THE HEADLIGHTS. Engine and headlights should be OFF.

I have had this problem with my 2011 fluidic verna from the very beginning and on escalating the issue they did replace both the headlamp assemblies under warranty but after driving in the rains it also had the same issue. I still do have condensation issue when driving in rain and does go away after like an hour or so. Haven't bothered to do anything with it since there hasn't been damaged caused by mositure to reflectors nor the casing.

About consumer court too, I need some guidance from someone who has gone through a similar experience like this.

Actually the dealership sucks to the core. They won't give in writing anything. Since they are the only Skoda dealer in our state so Skoda also isn't taking any strict action against them. Any plan c or d?

Tried point number 1 for 5 to 10 minutes no condensation, I think and this is my personal perception only and I might be wrong, the condensation starts when we turn on the headlights and drive maybe the headlights+air causes it, again I am no expert.
Will try point 2 and get back.

About point 3 and 4 there is no electrical plug in the garage. I can try with the vacuum cleaner if its wire reaches the headlights but it won't solve the purpose, right?

In your case it happens during rains and that is acceptable during change of weather but in my case it happens every night irrespective of the weather. Moreover I am pretty sure that in your case they replaced the headlights with the new one's and not from some demo car's.

I have asked this question in some foreign automotive threads too, can I post the links here?

On a personal note what I have noticed is that in every state there is only 1 dealer of Skoda, maybe 2 in big states. So, these dealers are like kings and even if Skoda India wants they won't be able to help the customer as these dealers are their only source of income. This thing sucks.

Hello,
Its nice to see an Member ready to fight to the core for getting things perfect. I like it.

I did read those threads.
People have exhausted all logical options on those forums like we have here. We need something different. Does the headlight comes with auto washers? If so is fluid shared from Regular windshield washer? Or separate? Try keeping those empty.

Take a long extension cord and get a hair dryer. Keep Hair drier running on LOW in various positions from behind the headlight. About 5 mins each..

Its very sad the way we get treated in India. As the issue to so common, even in other markets, Skoda deserves class action law-suit for poor quality headlights.
About your questions-

1. Xenons do run cooler than Halogens, But not much. A Xenon bulb is still far hotter than what you can touch. And definitely above boiling point of water. I have LED headlamps on two of my cars and Xenons on one. This problem is definately not related to light source being Xenon or LED.

2. Long term moisture could cause scale deposit on inner surfaces of headlight. Making them yellow or faded.

Which means headlight itself is calling for condensation. Engine isn't blowing something into headlights and point 2 should confirm it.

Vacuum cleaner is a different device. You need something to heat the headlights and for that you need hair dryer.

However, these are just diagnostics to find reason of the issue but you still need an expert to check personally. Is there Bosch, 3M or reputed service centers in your city? If so, why not let them have a glance on the issue? Expertise in headlight projectors installation may also help you.

Yes it comes with headlamp washers and the water is shared from windshield washers which is already empty.

I really don't understand 1 thing, the windshield washer is empty. I haven't water washed the car in about the past 5-6 months so from where the hell is the water coming from? Fine it might be inside say from wherever but wouldn't the same be evaporated by now? Also the headlights were changed twice, demo headlights is a secondary matter, wouldn't this had caused the water source or water/moisture stuck to eliminate? The dealership did not check the stuff fully for any moisture present, they only checked it for leakage or breakage and I am sure about it because if there was any then they would have charged me which is the only thing they are good at.

What should I do to prevent this then since neither the dealership or Skoda India is doing anything :(


Many foreigners are facing that issue and for the most the issue goes away after turning on the headlights as per the manual but no one is facing it everyday like I am. Please keep an eye on those two threads as some are saying that the temperature difference is causing this and some are blaming water.

What does this mean??

I will try to find an electrical source for the dryer but I am not sure about it.

Unfortunately there is no Bosch or any other reputed service center here. We have few desi one's but I don't trust me. Found someone at some forum but his location is very very far away from our city.


Many people are suggesting me to open the headlights, dry them or put a silica pack but I am interested in finding the source first as even if by drying the problem goes away but it will come back eventually but to find the source is like finding ache din.

It seems that your headlights are too well sealed. Like they are missing a breather or a vent. This is not allowing Moisture/Air pressure From inside to equalize from outside. Think about something like a pressure cooker.
Somehow the water went inside (During Installation or Manufacturing) and has stayed there.

The water is turning to droplets which then falls to the bottom of headlight when parked. But when they are turned on, Heat from the bulb causes water to form steam, which is causing Condensation/Mist as faced by you. This is the only logical explanation I can think of.

Fiddle around with the rear of headlights. Get a local mechanic to remove battery etc so you have better working space. See if there is a dust cap or vent of some sort. See if this is being obstructed by something.

Means nothing is going inside headlights (through vents if any), i.e liquid vapor from leaking pipes (radiator or etc).

Use hair dryer on headlights when it has condensation and check if it goes away. In normal case it should clear out through vents otherwise there are no vents or blocked.
