Mercedes CLS55 AMG W219, Replacing The Supercharger Idler Pulley
Posted in Mercedes CLS55 AMG W219
I noticed that the supercharger idler pulley had quite some dirt accumulation on it and also felt a bit of play, so decided to replace it with a new pulley. I made the right decision as the grease was escaping and therefore attracting the dirt.
Runs smooth again with the new pulley. When I will upgrade with billet pulleys, I will also replace the tensioner itself.
