"Chik Chik Chik" sound from the engine during cold start

[xaba]

I'm driving the C180 7 G-tronics (11 month old).

 

Recently, I realised that the car is having this "chik chik chik" high pitch sound from the engine during cold start.
It rhythm will slow down with the increasing temperature.  When the temperature reaches about 80 deg Cel, the sound disappears.

 

The sound is not quite audible from inside the car, the sound proofing of the car is pretty good.

 

Any bro encountering the same thing?

I believe is the Catalytic Converter

 

It happen when the CAT is cold and the engine warm up at a higher rev to make the CAT to it optimum temperature faster..

Is it normal then to have such sound?

 

I still hasn't got my new MB but when I saw this C180, prob less than a yr old judging from no. plate and the looks, parked nearby and when she walked away, I can hear that tick tick sound from the car.

Since day one, I have this tic tic sound, but C&C claim its normal.

The tick tick sound from the rear during shutdown is pretty normal with Turbo car.

But the whizzing sound from the engine at cold start ... I'm not too sure. Also, it disappears when the engine temp hits abt 80.

i had this problem as well but recently rectified by C&C. 1st i send my car in they couldnt isolate the noise as it only come during cold start ie. early in the morning. when i drove my car there its alrdy warmed up and nothing can be heard. i was reluctant to leave my car overnight hence what they did was jus some lubrications on the belt pulley. for the 1st week everything was fine after that and it came back. send my vehicle in again and this time round they changed the belt. no more screeching noise during cold start ever since.

Thanks bro.  I'll bring my car in to let them check.  Do you have to make an appointment with them for such incident?  Or do you just drive there and report the problem?

[Jayson]

call up the service centre and book an appointment. All the best. Cheers

Maybe they wanna cut cost. Initially my 1st trip there to rectify the screeching noise they only lubricate. Best thing is i leave my car there for 1 full day. Sigh
