Ridiculous condensation
« on: 09 November 2019, 07:40 »
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?

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.
