2015 C400 vibration a 2200 RPMS
I have a 2015 C400 with 127k miles. I had to replace a broken flex pipe that would rattle badly at 2200-3500 rpms. After the flex pipe was replaced I now have a vibration at the same rpm range. It is felt in the gas pedal and steering wheel and is audible. It does it in park and in drive. Any ideas what could cause this?

Find a MB specialist to replace your 2x engine + 1x tranny mounts.
About being proactive...
> Inspect the plastic coolant elbow hose at driver side firewall. It's likely leaking now.
> Shaking... when were your spark plugs last replaced??
> CPS protective pigtails installed?
