Sunroof Speed and Temp Test
I tested my sunroof to see if MB had designed it for the Autobahn speeds.
It opened without any problem, but failed during closing. It closed partially and stopped. I had to press the close button a few times to close it.
Since then, I have noticed a slight hesitation while closing (ambient temp 87 F).
In the morning (ambient temp 55 F), it opens without any problem but closing it requires pressing the button a few times.
It is possible that something is mechanically wrong with it, but the effect of temperature is strange.
