Tiguan :: Windshield Constantly Fogging Up
Jun 23, 2011
Having issues with the windshield constantly fogging up?
I love my car, but this is a large annoyance for me. It seems as though the heat is escaping from the engine bay and being ducted directly into the lower half of the windshield. I know it is occurring on the outside of the glass because I can wipe it off with the wipers, but it just keeps coming back. Sometimes, it's so bad that I can't even see the road...
I do have the APR Carbonio intake installed, and I'm wondering if the intake tube that parallels the windshield has a leak somewhere.

I traded in my 2009 Sonata for a 2012 Elantra Ltd recently and I have had an issue with the headlights, Both of them are constantly fogging up on the inside, Anytime there is rain, even light rain the headlights fog up. Especially when I wash the car, I was thinking about taking my car into the dealer and having them repair or provide me with new headlights.
I have read that the headlights are vented on the back but this does not make sense for them to leak like this.

Ok so it was 93 degrees and quite humid...guess around 65-70%, in Dallas. I got the fogging problem with 3 distinct circles on the windshield. I tried several settings.
Keeping the front dash (eye level) and feet level vents on seems to work abit. Keep the air away and from going to the windshield.
Then if it still fogs up...Hitting the 2 "Recir" buttons alternatively seems to work.
This may not work in FL , VW needs a better fix than just sealing those vents and stopping airflow to the windshield completely.

My 2010 Tiguan's windows are always fogging on the inside. When backing from garage, when getting in after sitting in a parking lot, temperature and humidity seem to make it worse, but it happens under all kinds of conditions. My Jetta sits right next to the Tiguan, and it rarely fogs up.

My current issue is as such: I started my car the other evening after a long day at work to find that when I started the car (I always leave the heater/AC control in bi-level mode with the a/c on with the fan at low or not on at all, unless I need the floor heater or the defroster) the interior of the windshield as well as the side windows instantly became fogged up. It took close to 10 minutes for the windshield to defog. Upon arriving home from work, I checked the reservoir where the coolant is recirculated and found that it was bone dry.
After the vehicle had cooled down, I popped the radiator cap and indeed the radiator fluid level was down. I replaced close to a 3/4 gallon if not a tad bit more of 50/50 mix. The next morning I started the car and the problem was still there and it took a few minutes for the heater to heat the car. Last evening and then again this morning, after the engine cooled to ambient temp, i squeezed the upper and lower hoses and there was still coolant in both hoses and thought this was odd, but I started the car w/o the fan on and the problem seemed to go away, but I noticed it didn't take any time for the car to heat up. Taking all of these things into account, is this a heater core(no coolant in cabin) or water pump problem or simply a bad thermostat?

I just had the 30,000 mile service at a dealership, replaced a leaking water pump, front and rear brakes. The car has just 30k miles on it so it hasn't needed anything major despite being 10 years old. Once I got it back the front windows and windshield are fogging up. It doesn't seem to matter if the car just started or has been going for a while. We have had temperature changes and humidity changes in the weather, neither makes a difference. I have to drive with the windshield defrost on all the time. The dealer said it isn't anything they did, but it started immediately after I got it back. Is it possible that they knocked something and broke it?

I drive two 1999 Caravans, a base model and a Sport. With both I have a persistent problem with moisture in the heating/cooling system. When I turn it on, it smells and feels moist (not like coolant), heat or A/C, summer or winter. I have pressure tested, no leaks. I have replaced heater cores, o ring seals, checked the condensate drains for blockages, replaced the metal tubes that go through the firewall on one car. There is no moisture coming from the outside. The windshield starts fogging at about 34 degrees and gets so bad when it is colder that the defroster full on with the A/C on cannot completely clear the inside glass. Really cold (for us) 20s and the windshield is so fogged that driving is scary. When I drive into a cold spot in winter, sometimes the whole windshield will fog in a few moments-- that's with the defroster on.

So I'm about 10 mins from home today when the coolant low/overheating dash light (the key light) came on and started flashing. I got off the next exit and pulled into a Wal-Mart and notice I had no coolant when I lifted the hood. There was a strong coolant smell so I looked under the car and it was pouring out.
I got some more put in to get me home. I was 5 mins away and by the time I got home it was completely empty again. I can't see the leak looking from the top of the engine. When I look up it's coming out on the passenger side at the back of the firewall.
I filled it back up and just pulled the car into the garage. 7 hours later and the coolant is still full so it only happens when I'm driving. There was no oil present in the coolant leak. I pulled the oil dipstick and it looks normal, no milky color.
I'm having it towed to the local VW dealership tomorrow morning but just wanted to see what everyone's opinion on the issue might be.
Only 33K miles on the Tiguan The engine never ran hot. The needle was right in the middle the entire time. No engine mods other than a Chip, Intake, and Catch Can. I've yet to hear about either of those three mods causing this issue.

My washer fluid low light is constantly ON, even if it is 100% full. I even ordered and filled the OEM washer fluid, but no change.
After reading though a lot of forums i realized what the actual issue was. i used the crappy orange Rain-X that screwed up my washer fluid sensor, like everyone else's.
U was looking for a DIY where i can change it myself, without taking it to the dealer.

So it rained today. I go to turn on my wipers, and they sound like this: [URL].......................
Clattering and skipping, only for the driver side. So I go to look at the wipers, and they look fine. Put it into service mode, and driver side is not flush to windshield. Took off the windshield blade and saw that the piece that attaches the blade to the arm is crooked. And then there's a slight bend in the arm itself. Pictures show it not very obvious, but is noticeable in person. And there is a bend on both, but the driver side is much more bent than the passenger, and its also at a different angle, hence the crooked attaching piece.

Recently the low windshield washer warning light came up on my dash. I rarely use it so found it weird. As I thought it was pretty full already. The warning only show up when its around 4 degree Celsius and doesn't show up when its around 10 degree.

So my brand new previously gorgeous tiguan, which is only 20 days old, unfortunately had a ding on it on the panel between the windshield and the passenger door.
I drive about 60 miles daily to and from work (and didn't notice anything like that on the car this weekend), so im guessing a rock or something kicked up and nicked the car. Paint doesn't look to be scratched or anything.
Of course since my car is new, im pretty frustrated and annoyed. I know dings will happen but I guess I assumed the body was stable enough to deal with minor kickups.

I would assume that my sensor needs replacement. What it takes to access the sensor? Where is it exactly located before I start ripping apart everything.

Well we got our first snowfall here and since buying the Tiguan and I had to clean windshields this morning. Go to lift the wipers off the windshield to clean under them and "THUNK"; they don't lift higher than a couple of inches above the windshield and they certainly don't stay there while I'm trying to scrape, brush, clear off snow and ice. The hinge on the wiper arm is below/under the trailing edge of the hood! This is a horrible design flaw.
Not mention that when knowing that we are going to get horrible freezing rain/snow, I would typically lift my wipers while away from the car so they would not freeze to the windshield. Clearly I cannot do this on the Tig.
This design flaw will lead to faster wearing of wiper blades through ice not being cleared and blades being frozen to the windshield in wet turning to freezing weather, a fairly common occurrence here. Like last night.
How do those of you in wintery climes deal with this issue? Is it only on the face-lifted '12s and '13s?

Replacing my HID bulbs, and I thought the the driver lens was just more scratched or rock pitted than the passenger.
However, it appears that their is some fogging or dust inside the lens. It doesn't seem to be actual moisture - it appears almost like a layer of dust or residue - perhaps it had moisture at one time that has evaporated or vented out.

I have noticed that the interior windows fog in the morning after leaving our garage. If the temps are in the 40s-50s, I will have the heater set at 72, outside air coming in, fan set at 1. Within a half mile I have to put the defrost on and engage the A/C. At this point the windows clear, but as soon as I disengage the A/C they fog again. I don't recall having this happen in the past. I have checked to see if there is moisture in the car, such as wet carpets, but everything seems dry. It seems crazy and wasteful to have to engage the A/C at these low temps. Is this normal?

Windows tend to fog up VERY easily in their mk6? It seems like my windows in my JSW tend to fog up all the time. Day and night, hot or cool out. I usually have my AC on low when driving. Just seems like its a little more abnormal then it should be.

My '06 B6 2.0T windows get really fogged up when it is humid outside and it is nearly impossible to defog them. Takes forever and sometimes it's like driving a tank...only looking through a little piece of the windshield. Any info about this other than a manual wipe?

I bought some stock headlights that were retrofitted with projectors. The re-seals seem on but after a decent rain the right side light is completely fogged inside. I have taken the back cap off and it will dry out after a day in the sun but should not do this. What's causing this and is it fixable or not??

The headlights on my 05 V8 (12K mi) are starting to "fog" up a bit on the inside -- and all within the last 200mi or so. The fog doesn't appear to be the result of condensation inside of the lens. Instead, it almost looks like the glass is now dirty and, I'd guess, about 10% opaque immediately in front of the main projectors on both sides. It shows no signs of going away under any conditions. FWIW, the weather has been steady temperature-wise and has been quite dry for the last few weeks.
