Hi All,
I recently replaced two EGR valves after restricted performance and DSC light came on. However, the restricted performance still came on when idling so I cleaned the pipes from manifold to EGR'S which solved the problem. However, I then went through the gears hard in sport mode but when the revs got to circa 3000 and ready to go to third gear the restricted performance came on again. I have also noticed exhaust fumes coming from the left side of the engine even though I have replaced the flexi pipes quite recently.
After clearing fault codes from a diagnostic the one code remaining is P010D-22 which I believe relates to mass airflow sensor B. There is also one code which comes on intermittently which is P023D-22 which I believe relates to the turbo actuator or inlet pipes.

Does anyone have any knowledge of this problem and what might be the best way to tackle it?
Much appreciated if you can help.

 

Thank you for all the replies, it will take a bit of time to go through them. Lots for me to think about.
LOL pretty useless eh?
