My 2013 SL550 was recently in the shop to fix a pervasive background squeaking noise that had appeared during my 3 months of ownership and approx 1000 miles of driving. Fortunately the dealership was able to reproduce, acknowledge, and fix the problem. I'm reporting it here in case any other SL owners experience the same issue.

The squeaking occurred at fairly low speeds, e.g. 5-10 mph, but not directly related to road roughness. I only heard the noise with the top closed and it seemed to come somewhere in the rear and on the driver's side. I recorded a short 15-sec clip for my service adviser (you have to turn up the volume to hear it clearly, at the very end of the clip I turn on the turn signal so you can use that to gauge how loud the squeaking was):


The reported fix on my service paperwork was:

good they found the problem. Where did all the sand come from, wind blown beach sand or something?

I don't know why they reported a lot of sand & dust -- I don't live or drive anywhere near a beach. I do park each day in a somewhat sketchy area underneath the highway underpass and where they're frequently moving dirt around so my car is often dusty when I return. But I'm surprised if that could cause significant dirt/dust in the seals as I very rarely put the top down afterward. Oh well, just something to watch out for...

I appreciate your taking time and trouble to post this topic . Good to hear they found the smoking gun
I would never imagine a dust could be blame for a squeak at all lol
