Citroen ds4 2011 huge water condensation on roof

[Manchinga_]

Hi guys!

I just bought a Citroen ds4 2011 from a friend, they have it for the last 7 years, but the last 2/3 years they started having some water dripping from the roof specially during the cold months (they haven used the car much in the last couple of years which it could make the condensation worst) I'm going to attach some photos so you can see the huge amount of water condensation in the roof, can anyone have an idea of where it can come from or had anything similar in this model?

(Sorry for the quality of the pictures, but I was quite hard to put the phone in between the roofs)

Possibly the aerial seal.

I thought that but it looks fine, I will have a look. All the door seals looks fine as well

Yes, assuming they do not have a sliding roof, then the aerial base is the most common place for water ingress. These can be poorly sealed at the base and it's common for the aerial base rubber to be loose of not make a good seal. Automatic car / pressure washers and heavy rain are your worst enemies. If possible, the aerial base securing nut should be checked for tightness and then consider either a replacement if it's got signs of poor fitting or applying some clear silicone sealant at the base.

Thanks for your answers, I'll look at it during the weekend and I'll do an update

A friend that I work with has a Skoda Fabia that is a repaired Cat N (I think), he had no end of internal condensation issues. The cause of the problem was traced to a leaking tail light gasket that resulted in a wet spare wheel well. The resultant condensation on a damp day if the car was left standing, covered both front and rear screens and headlining. Perhaps look down instead of up?

I been to the garage and they told me it could be just condensation because the car was almost unused for the last year, (apparently is happening just during the cold months) all the seals looks fine. So I'm going to park the car on a sunny street and I will keep an eye if it build up water on rainy days

Just to make an update, the problem is solved, I was keeping the car in sunny streets for a few days and water is totally gone, there was a couple of rainy days in between and the roof is completely dry. So just a condensation problem.

You have sun in Scotland?

Not really
