I'm not doubting what you say, and i don't want to mislead anyone, i'm only reporting what i find.
As you say with the plug disconnected it threw a code and the message 'check component left egr positioner..signal wire open circuit' .
I didn't drive like that so i don't know if it was in limp mode.
Next i fitted the resistor to the disconnected plug and checked for codes with engine running and all ok..no codes..no eml.
Next i took the car for the 25 mile drive and as i reported the car drove perfect, no eml..no limp mode and 37 mpg, as i reported i checked for codes and got the code i reported 'egr control..the air mass is too large'
As i said this is with the EGR valve plug disconnected and the valve in the default closed position,
I'm no electronics expert but the resistor is preventing the open circuit that causes the pcm to throw the code, so as the car is running ok at the mo i will leave it as is and see how it goes while we work out what is causing the error message.
so at the moment the car is running with no swirl motor and no egr valve in the circuit and appears to be running perfect so we'll see how it goes
i am not recommending anyone do the egr mod untill we sort the error message.
I know what you mean about the maf sensor, i got the car back from the garage after it had new heater plugs and the eml was lit. i checked and had various codes including one for the maf sensor right, when i checked the right side maf plug was not clicked home,after i refitted it all the codes cleared
