Hi Community, I would like to ask if anybody here is driving with Long Tube Headers on the M156 Engine (Doesn’t matter if C63, S63, Cl63 etc.). My Car is running with them since roughly a half a year. At the same time may car has started to vibrate starting from 120 KM/H (Roughly). While going crazy and visiting one workshop after another and replacing random Parts (I better don’t say how much was unnecessarily replaced….) finally I found a good address who found the issue. And guess what, it’s the Long Tube Header.
