W210 E320 CDI Lacks Acceleration and EPC Fault

[shivamramsagur]

Hello guys, my mercedes w210 E320 CDI is lacking acceleration and shows EPC fault everytime I press accelerator to kick down. Sometimes the maximum rev will be 2000rpm. It exhausts black smoke everytime the accelerator is pressed. Sometimes the accelerator works normal but still does the black smoke. But most of the time it doesn't work. It is really frustrating and embarrasing when trying to overtake. Can anyone help please? Thanks..

You need to get any faults and the live data read, could be a number of things.

checkout boost line for leaks /splits, see if intake manifold flaps move and turbo actuator move (when no limp mode), try swap egr and turbo vacuum transduces.

Black smoke = insufficient air (boost)
