Hi
I see a lot of mk7 owners suffer from condensation this time of year but why the mk7?
Ive checked and I’ve not leaks in the car.
I’ve got a large silica bag in the car and it makes no difference.
Yesterday I put anti fog treatment on all the windows. Drove last night, left the car for an hour. Came back and my car is the only car in the car park covered in condensation.
Can anyone explain why the mk7 ???
Thanks

Is your climate control working ok? Do you have window protection/treatments on? Have you checked your door seals?
-
Yes to everything. Thanks
-
Have you replaced the pollen filter recently? Dirty filters dont allow the climate control to work at its optimum, also do you have it on re-circ mode? Both will retain moisture in the car interior.

Also check;
- the pollen filter isn’t saturated with water
- if the car has a sunroof, the drain pipes aren’t blocked and letting water into the cabin
- the carpets are dry (if they’re wet, probably a sign of leaking seals, or blocked pollen filter)
- water isn’t getting into the car around the door speakers, as the speaker seals have been known to fail
- there isn’t water in the spare wheel well in the boot. If there is, possible causes might be a defective light cluster seal, a perished drainage tailgate grommet, the rubber concertina sleeves that carry electrical wiring and washer fluid pipe into the tailgate might be damaged. Also check water isn’t getting into the boot around where the tailgate hinges are attached to the car body shell (a problem on early mk7’s).
- any damp / wet outdoor clothing and umbrellas have been removed from the car.
-
I’ve just checked the boot and the pollen filter and they are both fine. No damp carpet anywhere

My current trial that I thought of this morning is to leave the air flow button direction the the windscreen to see if air flow while the engine is off helps. After 1/2 hour parked up I had no condensation....
Maybe when the system is on auto, it shuts all the vents when you turn off the engine stopping air moving in the cabin causing condensation.
-
It sounds as if water is getting somewhere?
The humidity sensor is in with the rain/light sensor in the rear view mirror housing. I would also check the vents in the mirror housing are dust free?
-
I posted something similar re my Audi A3 - my theory is that for whatever reason VAG cars are more prone to this - bit annoying!

I’ll check for dust but I only get condensation when the cars parked. When the car is running it’s fine.

Here is a possible theory - When I start my car (2016 GTD) initially the heating and ventilation system doesn't do very much for about the first 5 seconds, as in next to sod all. After this initial time lapse, it all starts coming to life with the circulating fan cycling up and then the heating/ventilation process begins. I can only presume that the HVAC module has been setup to do this deliberately so as to ensure that the battery load is minimised as much as possible so as to ensure the maximum available capacity is there for the engine start up process and to allow the load on the electrics to settle before the ancillaries kick in properly? The downside is that in those 5 secs while sitting in the car (with doors and windows closed), is more than enough time (at this time of year) for the darned thing to mist up!! What I've started doing is unlock the car; hold my breath; open driver's door; get in; start car (still holding breath!) and count to five - circulating fan cycles up and then... b-r-e-a-t-h :laugh:
I know, it is less than ideal. Wouldn't mind guessing that there is scope to adjust the HVAC module through VCDS or something similar...?

Check the spare wheel well is dry as if you have a leak in the tailgate or around the rear light cluster, water will pool there and cause condensation.

Thanks for the reply. The car is misted up before I even get in the car.
I do wonder if the system shuts off all air vents coming into the car when you turn it off then open again 5 seconds after you start as you suggested.

I'd agree, my wife's 2018 Ibiza is a nightmare for this whereas my BMW hasn't any issues - both live on the drive overnight.
-
Leak from the sharkfin? That's been seen on here a few times. Check the rear headlining.
-
I feel your pain.
I have the same issue. Mine is 67 plate and on one occasion I got in my car on a damp morning and it looked like water had been sprayed all over the inside of the windscreen. The only way I could clear it was by wiping it down with a towel. Mine appears to have no leaks however I will check what others have said in this thread.
Is the pollen filter behind the glove box or under the bonnet?
-
Behind the glovebox. Watch a YouTube on removal so you know how to remove the pollen filter cover plate as you could break the cover clips I used a small screwdriver.
My pollen filter is a carbon one so is grey. For a second I thought it was filthy until I realised it was supposed to look like that !

I can only assume this is a wind-up?
I've had no issues with condensation with either Mk7.5. I leave it in auto, with ac on all year.
Daft question - OP have you made sure your ac is on?
-
Yes air is always on and re gassed last month.
Since leaving my air direction to the windscreen I’ve had no condensation in 2 days so far .....

His car is off.

I get in to a soaking wet windscreen, i reckon I’ll need a scraper for the inside when it gets cold like my old beetle used to

Yes, wasn't suggesting he leaves it running. But not using ac when driving could cause it to get condensation when parked. Simple really.

Any update on this post? :grin: Been reading through the replies and it's quite entertaining and interesting at the same time

I don’t think it helped in the end.
What has improved condensation is I took the rear door cards off, ran water down the outside window and sealed all the clips, speakers and rubber seals that were letting drips of water in.

Glad to hear. Sounds like a lot of effort for anyone that has this issue. Not sure if it will happen with mine yet. But I had it on my last 2 cars and scraping ice off the inside of the windscreen is a complete joke!
-
Mine seems really bad this year too, very frustrating - definitely nowt to do with AC
-
See I turned my AC off and got hardly any water on the inside compared to bottom half of windscreen so wet it leaves water spots and takes 10 minutes to dry with AC on

I haven’t tried that. Worth a go. Thanks

Well I just spent most of the day trying to find a water leak in rear drivers footwell. Noticed condensation on the window and checked the footwell. Wet but not sopping. Saw drips of water coming from under where the speaker is in the rear door. So took the door card off and immediately saw drips of water at the bottom of the speaker. Why VW thought it would be a good idea to rivet the speakers in I’ll never know. So I drilled the 4 rivets out. Removed the electrical connector and removed the speaker. Sure enough the liquid gasket has failed right at the bottom of the speaker. I removed all the old gasket to get it perfectly clean. Applied new liquid gasket, set it back into position and then put in 4 new rivets. After that I put another small layer of liquid gasket along the speaker where it sits. Then put the door card back on. Car is in the garage now with the heat on full whack to try and dry the carpet. All in all spent about 5 hours on it with lots of colourful language and coffee breaks. Checked the other 3 speakers and they seem dry but I’m guessing it’s only a matter of time before this happens on the other doors. Why they couldn’t use a proper gasket and bolts to hold the speaker in I’ll never know. Penny pinching ?? Hopefully it works now and it stays dry. :rolleyes:

I've got exact same problem on mine, it's booked in for its 2nd service in 2 weeks and I've reported the water leak to them along with a couple of other warranty issues. The garage have asked to have it for 2 days so they can identify and fix in one visit as I can't be taking back and forth all the time.
-
I’m out of warranty but I have so little faith in the dealership that I went at it myself becoase at least I knew I would do it right ! good luck in getting it all sealed up satisfactory.
-
After having my car for a few weeks no, I'm starting to get the condensation issue. The most annoying part is that there's condensation on the windscreen when I get in the car and there's no way for me to get it off without doing it myself. I start the engine and press the Windscreen Max button but it doesn't even touch it until I start driving. I could sit there for 10 min and I don't think the condensation would clear on the inside of the windscreen.
Another annoying issue I found is that when the car is parked I can get in and start driving, about 2 min later the inside of the windscreen starts misting up very fast as I'm driving. Obviously this is quite dangerous and the only solution I've found is to leave the fans on very low on the windscreen. Never had that happen on a car before where it starts rapidly misting up while driving, just after being parked.

Do you turn your heating off after demisting your screen? Do you not just leave your climate control on at all times?

Nice job although painstaking at least you know it’s done and done properly. The seal goes on the old Mk1 Fabia’s round the interior door panel so you have to seal it up with silicone as it’s all riveted. Guessing it’s the same style seal they use.
I’ve had condensation but only slightly and mine was the rubber boot that takes the wiring into the rear hatch. The clip had broken. That was a ball ache to swap out for a new one too.
-

Agreed as should just be left on however if Lordie has water ingress somewhere then when the climate control is just on auto it will mist up quite quickly again as it turns down to control the temperature on low.
-
Just tried something different one the way home today, now I'm even more confused. So I drove to a friends house with the climate control set to OFF.
On the way back about 5 min down the road I noticed a very very small amount of condensation with it set to OFF, so it set it to windscreen and the fan speed was on very low (speed 1 or 2). At that point the window misted up very fast in about 5 seconds and I was struggling to see where I was going. I had to really quickly hit the MAX Windscreen button while trying to dodge a poorly lit pedestrian crossing island in the middle of the road on a slight bend. Fun times. Luckily then it clears in a few seconds, but so annoying.

what did you expect to happen with the climate control set to off in this weather? It's damp and cold! Why don't you just turn your climate control to auto and then leave it alone? In just over three years of ownership the only times I've ever touched mine is on a cold morning where it goes to max setting on screen and then when it's finished it's left in auto to automatically do it's thing.

I think you read my message wrong. My window stayed clear when it was set to OFF but started misting up really fast when I switched it ON and put the fan speed to low, then only clearing when I whacked it up to Max. Never had anything like that in any of the other cars I've owned, was just saying that it seemed a bit strange to rapidly mist up when the windscreen setting is activated.
-
I think probably every car will do it especially in this weather. Misting when you switch it on from being off is probably warm air coming out of the screen vents and hitting the colder screen. Once the climate control is doing it's thing it clears very quickly. I would say just leave it in auto and let it keep the air to the temp you select.
