P0400 EGR Flow Malfunction
Hello,
Engine light came on again today. Showing a P0400 code. Does anyone know what this means for W220s? Searched but didnt see any in our section? Can someone please give me the run down?
This happend after I recently got it inspected.
Thanks.

Wow. No responses?
The CEL went off after taking the gas cap on and off a few times. Stayed off for a day and then came back on this morning. Still showing codes 0400, 5087, and 5088. Any help would be greatly appreciated.

Is this the part that will fix the EGR valve leak?
