Your Mercedes
C200 2015
Dear All

Kindly advise on your thought on the following symptoms...

Car - C200 - 2015 - Mileage 50,000 - Purchased under a year ago from Sytner UK and Service B - Major was carried out at the time.

The car shake/vibrate/wobble intermittently for 2-3 seconds approximately once in two weeks on average. The car may be idle in N mode or Driving anything from 10mph to 70 mph when this behavior will be observed. The Engine Maintenance Light will come up on dashboard and the Eco Start/Stop A sign (stays mostly in Amber color) will disappear from dashboard.

After switching off the car, the Eco Start/Stop A sign will reappear (Amber color) however the Engine Maintenance Light may disappear or stay for a day or days however will eventually clear itself.

A local mechanic checked the car and advised on Nitrogen Sensor replacement when I took the car for inspection for Engine Maintenance Light. The light cleared itself and may be it was the injector cleaner that cleared it.

I dont know when was the car battery replaced last or it may or may not need replacement now.

Currently, there are no light on dashboard and the car is running fine waiting for the next shake/vibrate/wobble...

Please advise on possible causes and tips to pin point the issue and fix it. Thanks
