Loud and rough idle cure w203 c200
Even after replacing the hose under or next to the supercharger ($12 hose) I was still experiencing an extremely loud and rough idle and after help off the forum I found the issue.
Idler pulley was cracked and resistant to turn as well as tensioner pulley. Alternator Pulley was ceased and needed to be replaced, as well as the A/C compressor was fried, wobbling and grinding bearings causing it sound like the supercharger was constantly whining due to the wobble of the belt from the A/C compressor being deformed.
I made a video of before and after as well as how to tell if the bearings are bad.
