Mercedes E320 EGR code P0400

[@eulisesj]

I have a 2003 E500 with the same problem thanks for the heads up

You have a very good video I like how you showed how that little vacuum line had a crack in it I will give you a call this morning I'm up here in Lagu

Thanks, gives me a good idea of what to look for. Getting the same code on my 99 e320 4matic wagon. Just got done replacing the CPS on it because that was failing, now i have this code. I am not a mechanic, but as complicated as these cars might be, so far everything seems easy to work on and diagnose. Just got a bluetooth ODB2 scanner and torque pro for android.

I do have Mercedes e320 2004 where can I find EGR to clean or replace? please help

[@leanidis300]

I have two MBZ Mechs that I've used in the past, both said the same thing, that the code may not mean that the EGR Valve is bad and could be as much as $2k to fix?! . One want $200+ to Diagnose and the other wants $400+ I'm tempted to tell them both to take a hike!!

I think this is the problem with my E320. I had a bad egr valve, that I changed. After a few miles I got the p0400 code again.

Hi. Somewhat helpful but you didn't show where the failed vacuum hose was located on the car. Can you please tell me which vacuum line you replaced? Thanks!

2005 should be same, right?
