Creaking roof

My G29 has developed an annoying creaking sound from the roof which, sometimes, disappears if I lower and raise the roof. Annoyingly it's in the section of the roof which is right behind my head.

Has anyone else experienced this and is there anything I can check or do?

Not a creaking as such but I've had a couple of issues with roof noise. One was resolved by opening and closing the roof with the car parked on level ground - the noise started after I closed the roof while driving, so it probably hadn't seated properly.

The other was a dealer job - the main power cable (I think) that runs through the roof was knocking against one of the struts, so they wrapped a bit of felt round it and it was sorted.

Thanks for that. I've noticed that the creaking sound disappears when the roof is wet.

What side of the roof does the power cable run through?

I had a similar issue with my prior e93 M3 convertible. My tech recommended using Gummi Pflege on all the exposed rubber areas. I used detailing tools to get it in the channels and at the interface points. I haven't had need to try it on my Z yet, but it might help.

Whatever it was, it's on the right, so somewhere between your head and the offside window.

PS a creak that disappears in the wet is possibly a badly fitting seal. When the seals get dry and dusty, eg with the roof down, they can move against each other. A bit of rain makes a nice airtight seal that cuts the movement and the noise down. Same issue with every convertible I've owned.

Yes I guess I havenít spent much time with the roof up until the last few weeks, but I have the exact noise just behind my right ear (RHD car) probably a cable like you say. Annoyingly my CRV has a similar noise in the A pillar.
