W212 Engine Noise
I am currently experiencing an issue with a mechanical fault sound originating from the engine of my W212 E200 model from 2011 with a 136 Horsepower (100 kW) 2.1 diesel engine. I am seeking assistance from fellow members who may have encountered a similar noise problem in the past and could provide insights regarding its source.
Thank you in advance for any assistance or guidance you can provide.
Best regards,




It sounds like one of your GLOW-PLUG is causing a non contributing condition... Is your engine now extra shaky from idle to 1500.RPM ?
Do you have a code scanner? This will help you a lot.
