Polo GTI 6r Bi-Xenon headlights fogging up!!!

No problem, any time!

Thanks nomad,

Those photos do its justice nice work. If you get time take some in day but I think I'm sold anyways... I was going for the more aesthetics look and DRL but I reckon I'll be blown away with the visibility when night driving with Xenons.

Where abouts are you from? The Car doesn't look AU?

Btw the guy from OMTuning is saying the adapter is straight Halo to Xenons...

Not exactly.

The levelling system is designed to automatically compensate for vehicle loads. The sensors are supposed to be linked to the suspension, so it ensures that you don't dazzle oncoming traffic if you ever carry more than 2 passengers or a heavy load.

In Europe and Australia, it is a compulsory requirement for dipped-beam headlamps that have a luminous flux exceeding 2000 lumen, along with the presence of a headlamp cleaning device. Otherwise, the vehicle cannot be considered roadworthy.

A typical halogen H7 bulb has a luminous flux of 1500 lumen, but a typical gas-discharge D3S bulb has a luminous flux of 3200 lumen - so you understand why its light output needs to be strictly controlled.

As a courtesy to fellow motorists, you should at least ensure you are able to manually adjust the beam when necessary.

In having said this can you actually manually adjust the lights and what does the controller from inside do now after upgrading lights, does it move then accordingly? Couldn't you have them always facing slightly down.

Lucky it's a new car, don't need a pink slip for first five years so there would be no rejections.

@bassik

After all attempts I couldn't get the controller from inside the car to work with the xenon motor. The motor on the original headlight assembly uses a varying dc current that speaks to a circuit board contained on the motor. Along with a variable resister, it creates the "steps". Quite smart acually, a good way to use cheep components and make it do a fairly complex task. Anyway the motor in the xenons is a true 4 wire stepper motor, this requires quite complex control from the computer in conjunction with the other levelling motors. At the end of all that, no, there is no adjustment except for what u do manually.

Haha that's ok, I guess I could have handled that previous post a bit better but hey, were all human.

Hey just curious but why does everyone think I'm not from here. It does say on my profile I'm from Wantirna, Melbourne. I do live in Australia. I really dont know where people got the idea that I don't.

Anyway, yeah my car is left outside but that's not when it fogs up. It fogs up if the temp is about 10 degrees under and I'm driving with the lights on for about 30mins. If I then stop it goes away within 10mins. During the day I never get a problem. I was really just wondering if this could be considered normal. Apparently some AUDIs with xenons have have the same condition.

Assuming there is no sealing problem with the headlamps itself, it may just be a case of allowing any trapped moisture to escape? Try driving around with the lights switched on and the rubber caps removed temporarily. This may or may not be sufficient. Failing that, you may need to find an alternative way to dry the air inside the headlamps.

Yeah I have tried everything to get rid of the moisture in the air. Really I was just wondering if it happens to others, so I can consider it normal(ish) and think about it less.

I only ask because I noticed on your Polo that the little towing plug on the right hand side is a circle not a square like mine. Also you have a German flag which could mean your just a Deutschmen...lol

Try using a blow dryer to dry out the inside and then when driving around at 10 degrees temp analysis where the first condensation occurs. I'm not expert on lights but do Xenon lights emit heat like halogen, this could be a concern?
