Should this be unplugged?
I have a 2008 S550 4Matic and after trying to find the source of a hiss coming from the drivers side of the engine bay (unsuccessfully) I saw this unplugged by the MAF sensor. I couldn't see where it would plug in, but it seems odd to have it just hanging out. Does anyone know what it is?
