Hello,
I've just noticed water droplets in the nearside iD Matrix headlight housing (see photo)
I telephoned the dealer and they told me they would need to check with VW HQ to see if it is covered by warranty. The car is eleven months old.
Has anyone else got this problem?
Thanks

There'll be breather holes in the casing to stop the housing imploding or exploding (not like a bomb, but enough to rupture the hiusing) with temp changes. Occasionally the rubber grommets that seal the electrical connections to the headlight aren't seated properly, or you have people blasting their cars with a power washer and water gets where itdhouldn't. Not really a problem with halogen or Xenon bulbs that generate enough heat to evaporate the vapour,but LED just don't get that hot.

Probably a warranty claim unless they strongly suspect a cause like impact damage.

Thanks for that, The one thing I can safely say is that I've never used a pressure washer (I don't like them) I wonder will the condensation evaporate eventually, anyway I've it booked in with the dealer on 8th October.

What on earth do they mean by "to see if it is covered by warranty"? It's within the warranty period for god's sake! Did they deliver the car with water in the headlights? Are the headlights a repository for the screenwash? I am beginning to wonder if VW have learnt anything from dieselgate?

There is tge possibility that the housing is cracked from an impact e.g something tall with overhang gently backed into the headlight, cracking the housing.

Highly unlikely, but not impossible. Hopefully it'll be an obvious cause like incorrect sealing grommet assembly or similar allowing water in.

VW UK will be expecting the dealership to inspect and appraise for authorisation to repair or replace.

Then doesn't the dealer need to inspect the issue before referring it VW HQ?

Presumably they check the unit for assignable cause and then get the work authorised by VW UK who may also check if its a common issue etc?

Dropped the car to the dealers this morning and they have agreed to replace the complete headlight.
The new one will come from Germany and may take a week or so, anyway I'm relieved it will be rectified.

Hi. I also have water in my headlight. Left worse than right. When really bad causes a very diffuse beam. Was told could constitute a MOT failure. Took car to Lookers, Guildford. Was told the images I supplied were not taken “ at the correct angle” so VW would not considering replacing headlight units. I asked Lookers if they could send me the contact details of VW and the “ correct orientation “ of the photos needed. They send me information that states that condensation in the light is “ normal” .Could any one comment please?

They, VW or the dealer, are probably just trying to weasel out of paying for it. Normal for car dealers and manufacturers in my experience. I would persist with badgering them

Thanks for your comment. Is there a suggestion that this is a common ID 3 problem?

Definitely not normal. Some dealerships just don't like doing warranty work as VW only pay about £40 an hour for doing it. Take it to a different dealer and avoid that one in the future.

Ultimately its the supplying dealership you have to chase if VW UK won't do the work under warranty. If it comes to that, you light need a report from the AA or an MOT station to say the headlights as they are would not pass an MOT and are therefore unsuitable for use.

It certainly isn't normal. The design of the headlamp lens, reflector and beam pattern is totally compromised with condensation. That is why it fails an MOT. I have only seen this on cars where a grommet or bulb seal has failed in the the rear of the lamp.

I wonder which electrical fittings are specifically designed to allow water inside? Answer - none. Suspect missing or failed grommet or seal as mentioned above. However VW cover themselves by stating some items are subject to slightly different warranty rules and have an element of wear and tear related to driving style or external factors. See below:

"Items where the lifetime of the component is or can be influenced by driving style and external factors will only be considered under the terms of the warranty for a period of six months or 6,500 miles (whichever is soonest). Beyond that limit, the defects must be classified as wear and tear and will not be covered by the vehicle warranty unless a clear manufacturing defect is identified". Lamps and headlight adjustment are mentioned:

Did you manage to get this sorted? I've just spotted exactly the same issue, so let's hope my local dealership don't want to play silly buggers.

It seems plainly apparent that this is a fault which should be fixed under warranty.

No they have not. They are defending dieselgate.
Then EGR failures after the software update.
I hope they lose big time.

Mechatronic failures as accumulator cracks. Worldwide recall except UK. VW just do not care.

VW are the worst car brand I have ever dealt with. Yet, my wife chose ID.3.

There will be so many issues. I dread to think!

Hi all, I've just read down this thread, most intriguing. The issue has happened on more than one vehicle and there is an assertion that it constitutes a failure of MOT. If the issue affects more than a certain percentage of vehicles surely there should be factory recall to replace the headlight units and address the root cause of the issue on all ID3s. If you have an accident because of poor visibility related to this then will VW end up in court?
LED lights are common on multiple vehicle models now, is this a problem elsewhere or unique to the ID range?
Ask for your dealer to provide details on the number of customers with the same issue, it might nudge their thinking. Or get onto Fully Charged or Which.

It is clearly a problem on some vehicles but I don't think a few reports here is evidence enough to suggest a recall. What I found more a surprise is on one post a dealer had said its normal or acceptable when it clearly isn’t. It can only happen if a seal in the unit is poor and damp air can enters then condenses out on the inside in cold weather.
With LED lights there is little heat generated to assist in drying out a failed unit so any dodgy seals are soon noticed. They have to be covered by normal warranty.

I think condensation in the headlights has happened on nearly every car I’ve owned.
