Sl55 squeaking noise and roll bar issue
The car is a 2004 SL55 with 40Kmi
1) when I press the gas lets say more then 35% (approx) I get a squeaking noise that does not last (less then a second), kind of sound like a bov (blow off valve) from a turbo charged engine (vented to the atmosphere) just not as loud.
2) The roll bar/windscreen does not come up 100% when using the button on the center console (not as a security measure under aggressive driving etc.), and the back smaller windows won't come up neither (when convertible top down). I am not sure if the windows should come up or not.
When I lower the windscreen/rollbar I push the button untill it the engine stops and the roll bar lock in place. But when I try to put the roll bar up, it stops before it suppose to and the engine keeps "trying" but the bar doesn;t go past a certain point.
Does anyone has any idea about how to solve any of those issue, similar experience, fixes or troubleshooting please let me know

When the top is down you need to hold the window button in the up position for a little longer and the smaller back windows will come up. The BOV noise is your supercharger clutch engaging you can do a search and find many articles on the subject. Hope that helps.

You my friend have the supercharger clutch squeek. Learn to live with it because the fix is elusive. The squeek is not harmful to your engine.

The other stuff about the window and squeak is correct. You can replace the clutch assembly on the supercharger or try a couple other methods to "resurface" it lol.
