04 CLK55 P0440 CODE *HELP*
I have a P0440 code in my CLK55 and cant figure out what it is.
All the vacuum lines look good, no cracking, and I changed the gas cap off my c55 and the light will still come on.
P0440 exhaust gas recirculation flow
I changed the little ticking purge valve in the driver side near the headlight.

I believe the 5.5 has dual egr with sensor they are on top and in the front of the motor.
The EGR sensor/valve might be at fault, try removal and cleaning with carb spray before replacement.
