Not saying it’s 100% the sunroom just best guess.
I’ll take some photos tomorrow morning.

I have had a couple of Mk5's and found the door seal joints at the bottom of the car come away from the bodywork........which then lets in moisture that creates condensation.

Was it sunny following a cold night?
Had a windscreen replacement recently?

can’t be sure on the windscreen as it was a recent purchase.
I think it’s sorted now, I think it was just sat for a while, I took it for a 4 hour drive with heaters on max a few days in a row hasn’t happened since so fingers crossed

It literally only happens over winter when the morning sun heats the car up after a cold night. Black car parked outside on a south facing drive. Sh1t happens.
I just live with it and keep a chamois in the glove box it happens so infrequently.

My wife's mk5 suffered badly and it stopped when I sorted these out.

One thing I did notice is the sunroof seems to be sitting proud of the roofline. It was flush when I bought the car but over the years it seems to be slowly making a bid for freedom. Could be another source of water ingress.

Checked my seals today and they seem OK. Will any issues with those be obvious? They seem securely attached with no holes or rips. Pollen filter looked OK as well.

Do these cars have sunroof drains? I do not have a sunroof on mine so cannot check but most do and it is nearly always the reason for an issue with water leaks as the drains become blocked or the pipes that connect to them shrink with age and become unattached behind the trims.

They do indeed. I think the drain tubes live behind the arch liners though, so not a quick check unfortunately.
Maybe open the sunroof and pour some water in the sunroof gutter. If it stays there in a pool get the strimmer wire out and gently feed it down the drain or put some kind of tube on the hole and gently blow down the drain. If it runs away and does not appear under the car somewhere you will have to act like Columbo and find where it is going :) Ho and one more thing (See what I did there) maybe get a new sunroof seal?
