I am a little picky as a car owner. My 2019 SL400 creaks a bit with the top closed. goes away completely with the top down. Is this normal? Thanks.

Try cleaning and lubing the seals around the windows, and as many top seals as you can get at. There's a MB recommended lub for the seals called Krytox. Here's a link with a bit more info:

No noises in mine, but as mentioned you should try to treat the seals, etc.

Mine often makes a noise that sounds like wires vibrating inside, but if I give the plastic panel on my side of the roof a rap with my hand, it generally goes away until I put the top down then up again.

I had an intermittent ticking noise in my 2014 SL with the top up that seemed to be coming from behind the passenger seat. Couldn't find it.

I subsequently had the trim out behind the passenger seat for another reason and discovered that the large trim piece behind the door opening had one retainer that was bent over, so it wasn't seated. I straightened that retainer when I put everything back together and made sure it was properly seated. After that I never heard the noise again. I suspect the noise was there with the top down as well, but you just couldn't hear it over road noise.

Thanks to all for replying, I will now go to the MB dealer and see about buying the seal lubricant - of get the exact name and find it on line. Will chime back in once resolved (hopefully).

I haven't used it myself, but have read a little goes an extremely long way and to use it sparingly.
Good luck!

This video show an R230 but the principle is the same...

As a fellow car enthusiast, minor creaks and noises with the convertible top closed are common, especially in older models. If the noise dissipates with the top down, it's likely just the seals or components adjusting.
