engine noise
Hi, new member here. I just purchased a 2002 c230 coupe (26K miles) and I was just wondering about the engine noise. I have tried to do a search and I looked through 8 pages of c-class w203 section of the forum but no answer. I noticed that the engine is unusally loud, I mean to the point where it's embarassing to accelerate next to cars with their windows down. Ticking noise for the first minute or so after starting the car. No one I know owns a coupe so I really can't compare the noise to see if it's normal or not. Service advisor said that the problem couldn't be duplicated and the car sounds normal. It sounds worse than a 88' honda civic. Others say that it's loud because of the supercharger so that's what I thought but the more I hear it the more I get worried. Please help!!

Its an emissions thing. The sound is indeed the supercharger. A bypass door opens and sends compressed air from the supercharger onto the catalyst. This preheats the catalytic converter, allowing it to meet ULEV status.
The sound is perfectly normal when the engine is cold, and usually goes away in 30 seconds.

I have a 2002 c230 couple just like you, it's a little loud when it warms up but after that it's fine. You have the same engine as the 02 and past c-class sedans. It's called the M111 which is 2.3 supercharged. The post-02 c230's have a m271 engine which is 1.8 supercharged.
Now if the noise is just way too loud then there's something wrong with the car. Go have it checked out. Why did you purchase a car without first driving it?

Mine does the same thing as everyone elses so I guess it must be normal. I wonder why MB had to design it to be so loud and rough at start-up. Emission purpose or not, an MB shouldn't sound like a lawn mower!

C200K (w204)
Check the exhaust system for leak, my friend has her car's exhaust system checked (C200K coupe) and changed due to leaking (not sure which part), before it was changed, sounds f*kin terrible, now it sounds the way it should.
