any c230k sedan owner has heard the ticking noise when it's idle?

It is probably just the fuel injector "clicking" you hear.

so is it normal or something that can be adjust so it makes less noise

It should not be considered normal. Take it to the dealer and tell him you want it fixed.

Specially in V6 engines...

This ticking comes sometimes not always...

but dont worry about it... because i faced the same and the munifactuer or MB V6 users feed me that its normal.. and it not ticking always.. i guess this comes when the engine get warm

i have the same problem with my coupe in the mornings.. i've always attributed it to the car warming up and figured that it's part of the whole coupe sounding like a lawnmower underwater thing

But those only make noise when they are worn out. This should not be happening on a new engine. It's probably the injectors. I don't think it's an issue unless it's accompanied by other problems.

For the car that I had before (2001 C320) the ticking noise came from the purge valve. They replaced new ones and noise went away. I suggest bringing it to the dealer and have them check it out...perhaps mention to them if it could be a purge valve.

Thanks.

Yes the noise you hear is the purge valve. If you do a search on here you can find many topics on this issue. What shocks me is that they still have not solved this issue on the 2003 models. What a disappointment in quality
