Hi all in forum land, I have a 2006 c230 sedan . Recently I decided to use my code scanner to check and see what may be the cause what I have been noticing as a lose of power. While the power lose that I have been noticing is very pronounced and I couldn't tell if it was real or just in my head cuz my car has no check engine light on . However once I ran a scan on it the DTC p0355 came up so I cleared it ,but the scanner said the computer still had the code stored in it. Does anyone have any knowledge of this problem and what I might do to resolve it? Thanks in advance. Ebudd1973

Nice website
There is a document in the Wiki as well https://mbworld.org/wiki/images/f/f5...stic_codes.pdf

 

Is Coil E the same as cylinder 5 (Middle on Drivers side) ? I don't see any references to E to cylinder numbers!
