EGR failed or just new gasket/plate
Hi. Hope you guys can advise.
I have a 159 2.4 Ti (57 plate) as of a few days ago i have absolutely no power under 1500 rpm. Sounds an obvious EGR failure to me, so it was into the garage under their warranty thismorning.
They just called me back saying that they have orderd a new gasket/plate for the EGR as this has since been modified by Alfa for this car and will be the fault and not the EGR valve itself. ( this has been advised to them by Alfa dealer !).
So my question ( and i am assuming I know the answer) is..... How can the gasket/plate that has been on the car and been running great can suddenly cause this loss of power and just by changing it for a modified one fix it ?
Surely they will find problem still exists after they change this ???
many thanks for any comments
