A bit more info:
I set up a dashboard in Torque showing Boost, Intake pressure, and EGR Error. Running the engine at various speeds showed that each was delivering live data. Critically, EGR Error always returned quickly to near zero after a change in engine speed. The engine was not under load here, but this does suggest that the EGR valve is working.
Can anyone tell me which sensor drives the "MID: $31 TID: $90" values?
Thanks
Andrew
