You have a leak somewhere. It isn’t from lack of use.

You will need to remove the carpets and sound deadening to dry it properly.

it can be really involved to find a leak. You need to see where the highest wet bit is and work from there.

What's worked for me in the past is a smoke test inside the car and you will see the smoke come out of the area where you have the problem.
I sa on YouTube No27 using a chimney smoke bomb on his Jaguar XKR to good effects.

Agree re it being a leak, but if not used and therefore no warm air movement it will not dry out and will still go moldy even if the leak is fixed.

You need to do both; fix ingress and dry the car out.

This is a well known issue with Levantes and Ghiblis.

The rear door seals leak, look for wetness in the shuts on the hinge side.

The water runs down into the rear footwells then works its way forward. All the wiring and modules are in the floor.

If I were you, remove both front seats and the carpet and have a look. Most of the wiring is on the drivers side so maybe just that seat first. Sometimes you can get away with drying and electrical cleaning all the contact, sometimes you can’t. There is also a big connector you need to pay special attention to.

Really good to know, given my leak was resolved with cleaning and reseating the seals, I am guessing that is not a long term solution... is there a permanent fix?

I am keen to know so I can get is fixed while under manufacturer extended warranty.

Thanks!

Congrats on your Levante! Gladly, I have few solutions which should help you regarding these problems.

As to the exhaust, it seems that the exhaust valves or actuators might be to blame. If it cannot be found it most likely is acted upon by an actuator possibly somewhere near the exhaust manifolds. In addition, it’s important, I think, to inspect the wires and fuse connections for the exhaust valve as well. If that is all okay, you may wish to have the actuator tested or even changed.

For the leaks, sounds like it could be coming from a few: First ensure door welts and sun roof drain if any are not credible. The problem with the front window might be also connected with a blockage of the drain channel. As for the rear footwell it can be due to a blocked drain or a weeping door skin. Regarding the boot, well you said that the adblue cap was off so you need to check whether all the seals and covers are secure. Often it helps simply to re-seal and clear those channels which had become blocked in some way or another.

Car is in with the Dealer now - apparently the leak is caused by water getting through behind the door card - the looks to be damage / kink on what looks like the door water membrane.
Also apparently the rear door wiring looms look like they are damaged - unsure how this could be caused!
Big question is will the warranty or goodwill cover this...
@conaero - any of this sound familiar?
Thanks!
