Gritty feeling engine!
I took my car back AGAIN just this week. They gave me a C 230 as a loaner. I live in Canada, btw. The C 230 engine was way way smother than my C 300 4 MATIC. The C 230 engine idles like the car was wasn't running at all that is so quiet and I can hardly feel or even hear the engine. When the car was running, the engine was so smooth and quiet at any engine speed and road speed. Unlike my C 300 4 MATIC. The technician said it is normal for the 3.0L engine to ildes loud and sounds gritty
I am still not convinced!!

But thats ridiculous. The 3.0 liter shouldn't feel ANY different than the 2.5 or 3.5 V6.

I hope it's not a typical drivetrain noise from the front AWD driveshafts, propeller shaft, bearings, etc.


Anyone has their problems fixed yet? Please let us know if you have your problems fixed. Thanks!

So, now the next step is for them to drive the car to see if it fixed the issue. If there is the slightest problem when I get the car back I will be dropping it with them again and initiating the Arbitration process for the Lemon Law.
I will have to take my car in again
BUT when I took the car back and start driving the car, I felt immediate differences. The car now feels a lot smoother and quieter when the car is running at it highest gear at 1500rrpm...NO MORE rumbling noise. Also, the transmission shifts so smooth now that I could even barely feels it. Most importantly, the engine idles a lot smoother...very little "feedback" to the steering wheel.
I suspected that there was a software update for the engine management system?? They updated it but they did NOT want to disclose to me for whatever reasons and just told me that NO issues were found??
In addition, they updated the software for the BLUETOOTH as i complained that the other sides couldn't hear me due to too much feedback. The problem seems to be fix as I made a few phone calls today and nobody complained that they can't hear me anymore.

Anyway, I am very happy now that the issue is resolved. Yes, I suspect that they may just simply got the software loaded correctly for both the engine and the transmission. Anyway, no more complains from me, as there are no more issues with the car. This is a very good car indeed and I enjoy driving it every seconds when I am behind the wheel.

Glad to hear you are, once again, a happy MB owner, but hate to hear the 3.0 is the noisiest of the bunch!
