What is your question?
EGR FLOW P0400 and Evap system large leak P0455 messages at the same time. These problems started after hitting a pothole.
How long has your 1998 Mercedes-Benz E320 had this problem?
A month

Hello, I do not see any possible reasonable correlation between hitting a pothole and a misfire code. The P0455 code could be from a fuel cap not fastened, for example, but could be another large leak that would seem to be physically verifiable. Your EGR flow concern would seem to be not related to a pothole either. Diagnostic testing is required to get to the bottom of all concerns.
