Hello all.

I'm hoping some of you here would have had some experience with roof/seal leaks on these motors.

I have a 2007 3L V6 alphard which was fine and leak free (have had it in Skye in worse conditions back in September). I went further north last weekend and it was rather rainy as you could imagine. Slept in the van overnight and in the morning it was much damper than usual. I noticed the roof liner where the A pillar is had quite a large damp patch on both the passenger and driver sides.

I drove 3 hours back home with the heater and AC on full, which dried the liner out completely.

Today I went out to use the van after sitting for a week and noticed another damp patch. Seems to be happening on the passenger side only this time, but the driver side is dry this time.

Any ideas would be appreciated. Is this common? Where should I be looking to try fix this? By the looks of my picture, I am not sure if it is coming from inside the pillar, or if it's above the passenger door and running downwards.

Picture attached!

Thanks a lot

EDIT: My alphard is the one with the sunroof and moon roof, but I doubt this is anything to do with the sunroof because it is happening so far from it?

Adding useful info Re: sunroof

Damp meters aren’t too expensive, when we had issues with a motorhome body leak it indicated the area where the source was.
