My R170 320 has a clicking sound when idle and is coming from the item circled in the image below. I have no idea what this is? It has on occasion stopped clicking but soon restarts not long after. Can someone help me identify what this is?

Hi,

That is Fuel Vapour Evap Can Purge Solenoid, it sounds to me like it is working normally ........................

When you stick your head under the bonnet of a well maintained and good Mercedes V6, V8 and V12 Engine that is really all you should be hearing, plus a faint Injector Clicking from under the covers :grin:

HTH, Cheers Dave
