hi all could somebody help me with this fault code

2511-001 check component y27/9(left egr positioner ) positioner signal fault.

2355-002 check system component egr control the mass is to large..

is it as simple as changing the egr valve

thank you
 
Give the EGR valve a good clean first to see if it clears the fault.
 
If this is on the E300, EGR don't generally give trouble, so look for a vacuum leak or ruptured actuator diaphragm.
 
hi dieselman thanks for reply no its on a 09 E320 cdi v6 if you can give me pointers cheers
 
As E270 owner says, try cleaning the valve, if that doesn't fix it it's either new valve or EGR Shunt time.
 
Yes.
