2008 Mazda 5 2.0 Diesel

Keep going in to a limp mode, cant go above 2.500 rpm power cuts out till rev return to 900rpm and throttle comes back alive. same in neutral

found EGR pipe Blocked with carbon, valve removed cleaned and tested to be working.
DPF filter not blocked,
Fuel Filter Replaced, Fuel Regulator Changed.
Lambda Sensor changed due to flagging up a issue on mazda health check on IDS, still no change although passed test now.
DPF regen completed.
No fault Codes on engine only one there is on the abs. but was on before this issue.

any help or suggestions would be great

 

What scan tool are you using?

 

using Mazda ids VCM2, not much on Delphi and snap on

 

Save a session & open a tech case with Mazda tech centre. They seem to see alot more that we humble techs can view with MMDS ( Mazda's name for IDS software)
