Spark plugs
I have 2012 C250 M271 evo. The Turbo air intake box is vibrating a lot at idle when touching, and the car vibrates on acceleration. The engine mounts are OK. I have cleaned the spark plugs to made them look as new.
There is a code P0340 which I have not fixes yet. How do I know whether the spark plugs are causing the issue?
Does Icarsoft, (150 dollars)scanner able to detect spark plugs functionality?

I had similar issue on my C250 2013. One of the coil packs was bad. Error Code P0340 - Camshaft Position Sensor Circuit Malfunction, not sure if this is the cause or something else is setting that error code.
