Damp carpets and condensation issue

[M4rez]

I have a MY18 Granturismo and noticed some condensation on the front windscreen and the carpets in the front passenger and drivers footwells are both slightly damp too. The car had been sitting on the drive for about three months during the winter and took it for its first drive of the year this weekend. Any thoughts on what the issue could be? I’m assuming it’s to do with the drainage holes near the front windscreen being blocked or some sort of AC overflow issue, but I could be completely off the mark! Any help and guidance would be much appreciated.

That’s highly likely what the issue is. Open the bonnet and check to see if there’s leaves by the hinges. If they are cleaned out and the problem still there; scuttle panel and wiper arms need to be removed to clean it all out thoroughly.

Or you left a window slightly open.

Thanks Dicky, appreciate the advice!

I’ve just had a look under the bonnet at what I think are the drainage pipes and they look swollen (photos attached) - Is this what they normally look like? Or are they full of crud that needs clearing out?

That some odd foam they stuffed in there. It pulls out, with a bit of wiggling (I'm talking specifically of the black stuff)

I think you need the scuttle panel and wipers arms off in order to access the drainage holes, as Dicky rightly points out.
The drainage hole at the fuel filler cap was completely blocked on mine, quick burst of compressed air sorted it and a load of black crud flew out under the car.

Is this foam a potential cause for the water ingress issue into the footwells, and therefore worth pulling out? Or is it normal for there to be foam in these locations?

It's normal, but may be restricting your view / also trapping debris

I’m not really handy with a spanner, but is taking the scuttle panel and wiper arms off something a novice can do? And is compressed air the only/best option to flush it out?

Or is this task best left to the experts? if so, is this a Maserati specialist job or could a local mechanic be able to sort it?

Pretty sure you don't need to take anything off. It's been a while but I think they are a little inboard of where you're looking. Perhaps someone can take a photo for you

Any local mechanic could do it in 15 mins.

Bring the diagram above and ask him to put the air compressor through the drainage holes.

See how saturated it is. It obviously has a purpose, it may even block a "non drain related water access point" on purpose...but if it is continuoly a saturated sponge then that will cause metalwork issues over time.
