W204 C300 engine chirping noise
Hey guys I recently swapped out the water pump and tensioner pulley along with the belt and it’s still making this clanking/chirping noise from the secondary intake pump area any ideas? By the way it’s a 2008 C300 3.0L V6 I’m stumped here guys

How about the idlers? The one on the top left is notorious for this.
