What can be causing excessive internal condensation on my windscreen .

Obvious question but are you running with AC on or off?

There are threads every winter on the same subject.

 

Water trapped in the door, passenger door if not opened.

So see the seal and the drain holes are oh.

Pollen Filter clean / dry.

No water in the spare tyre well.

Dry Carpets.

Use the AC when it works, above 2*oC. 

 

Put dump draps in the car and boot.

Clean inside windows and use anti fog.   etc etc

As rooted states you must have water in the car somewhere.

We live on the Pennines where it is said that we enjoy   9 months of winter and 3 months of bad weather, this year has been extremely wet but our Karok parked on the drive has never suffered excessive condensation inside in 4 years

On frosty nights we also get condensation inside the windscreen - but just the windscreen, all other windows are clear - and all drain points are clear, carpets dry, a/c on permanently and cabin filter was (supposedly) changed at dealer service a month ago. Only thing I can put it down to is the fact that we have the heated windscreen which is the all over foil type rather than thin wires. I guess the foil just makes the inside of the screen colder than if it was just glass alone and hence attracts moisture more than other inside windows. That said, it's not heavy (raindrop size water beads) levels of condensation - just a light layer, so is dealt with quickly with a couple of sheets of kitchen roll (thrown away indoors - not kept in car) plus boost button setting on screen demister. We also use a Pingi dehumidifier.

Thanks for your info.

Up until two months ago I have never experienced condensation problems with the car. The only thing that has changed is the guy who valet's my Koraq has started using a different glass cleaner on the inside of the windscreen and I do not know wether that can be the problem.So I will ask him to just use a window leather and a micro fibre cloth to finish, then if the problem does not recur then I will know what has been the problem.

I shall update my page in due time

Yes, valeters products can be terrible on glass / windscreen in the cold.

 

The stuff used on brand new cars reacts with what ever chemicals come out the new plastic as well as the AC and that horrible blue blume.

 

White Vinegar is as good as anything to clean off the crap stuff.

Or Meths, alcohol / spirits, or more expensive stuff.   Scrubbed with scrunched up news paper worked well enough for decades with Tight Scottish people like me.

 

As did DRY Rock salt in Marg containers with some holes pierced for damp traps,    But i do not grudge paying a £1 each now.  (Having made money cleaning cars properly. 

Thanks for your advice 👍

What are they?

Thanks. Must have been fat fingered last night on the phone. 

But what did you mean to write? The only thing I could think of was damp rags but you would not want them in the car, damp clothing in boot yes, did you mean the humidity absorber things?

Damp trap.  As illustrated by pictures of Damp Traps.   Just those who can not think for themselves.  Dehumidifiers is the name sold under now.   But not the ones you plug in to Dehumidify someplace.    Search Damp trap.  Some still retail as such. Or Moisture Trap, or Moisture Absorber.

Thanks, the photos were not showing for me when I read the posting, that is usually the first sign that my crappy internet connection is about to drop out.

 

If I don't see anything then I dont know that something is missing, yes damp trap is quite obvious now seeing the photos.

When my 2019 Karoq SEL DSG started having that problem I took it in to the dealership and they kept it for several weeks trying to find the problem.

Turned out the windscreen was leaking and water was running down the back of the bulkhead behind the carpet.

This is a well known issue with the Karoq which you will see if you google it. Check thoroughly to see if your carpet is damp and if so take it in for investigation.

You should not have any condensation at all if everything is sealed up correctly. I havent suffered any since the repair.

Is anyone suffering the issue this spring in the UK?

The only time I have ever had condensation on my windscreen was when there was a leak. Since the windscreen was replaced I have not had an issue.

It was a long drawn out process which was particularly disappointing as the whole of the cars interior had to be stripped.

If this does turn out to be your problem make sure to check everything after the work as I suffered considerable damage to various internal trims etc.

Make sure the scuttle drains are free of dead leaves and similar detritus.

My koraq was getting a lot of condensation 9n 5he front screen and eventually I noticed the rear side windows were misting, then I found there water in the spare wheel storage area. I complained to the head office in the uk. I was asked to allow skoda to let them collect the car and replace the drainage valves around the sunroof channels and I am happy to say I have never had a problem since.

Hope this heips,
