New, Need help
Hi all,
I am new with Mercedes and would most appreciate any assistance.
The problem is my C200K (Auto) rpm drops to a level (still above 500pm) where I can feel the engine /steering wheel vibrates (feels like engine dying but never died once so far) whenever I slow down to less than 10kmh, what could be wrong?
I have cleaned the idle valve, re-programmed as well tried with either C or S mode.
Other the above, everything works fine on the move.
Any assistance/sharing on this experience greatly appreciated.
Thank you

Isn't there an electronic idle stabilizer, which would not be susceptible to cleaning, etc. if it has become faulty? I think it's time for a diagnostic plug-in at the dealer!

What is your idle RPM supposed to be? If it is running below that, I agree with Sportstick that your engine electronics are likely the culprit with a faulty sensor being the most likely cause.

95 should be what is recommended by Mercedes.. It might not hurt to fill up on a tank of Shell Power-V, which country is the op in? I would always go with the highest rated if he's in Eastern Europe.

Dear all, thanks for the feedback and suggestions, most appreciate it.
Unfortunately, an engine diagnosis revealed no fault. I have tried 97 Octane fuel, still no difference. Air filter had been changed too. The RPM on idle is around 700-800 with the aircon and lights on. It is only when I slow down say to a junction that I get the symptons.
Could it be foul plugs? Gearbox? The mechanic had also checked the engine mountings and they are ok. He suggested that it could be a loose/worn alternative bearing taking an extra load.
Any one had these symptons before?
Thanks to all in advance.
