Very new to w202's and the forum. just bought mine last Wed. When i testdrove the car it had no cel on then Thurs pm cel went on. Obd2 code reader gave me a egress flow malfunction p0400. My engine runs very strong and idle is around 6000 rpm there's no rough idling whatsoever. I just want to verify since my engine and idle has no hesitation whatsoever could it just be a clogged hose or a really dirty egr. Looking for feedback since i need to get it snogged and theres no way this would pass with cel on. Thanks
