Anyone has clear solution for ticking sound from engine when accelerating?? I know it's got to do something with purge valve for c240 sedan, but is it the same for the coupe?
I brought the car to dealer and they said it's normal sound from a supercharged engine, but it definitely isn't the engine sound u expect from a MB..

Well MB's 111-engines are well known for not sounding that sexy you know. And yes, the C230K has the purge-valve as well. The bad purge valves usually ticks loud when idleing (to be drowned in other sounds on higher revs).

No, this has nothing to do with the purge valve. It is a signature sound of the supercharger, at least in this configuration. Mine has become louder and can be heard almost always, not only during hard acceleration when the car was new.

I hear the ticking on my car, but it's always been there from day 1 so I never thought twice about it, just the fact that the idle sounds pretty cheesy right now. Gotta get that muffler tip to drown out that sound.
