good morning folks and a happy christmas to everyone,im looking for some advice,i bought a 2014 A5 last week its a nice car and im happy with it but the egr valve is sendeing on the eml and the vcds is showing code P0401 00,insufficient flow.
now it was parked up for a few months so ive put in a cleaning additive and am using the car as much as possible,theres no problem with power.my question is should i get the valve replaced with a new one or get it blanked?i dont know much about this system of mapping it out and wonder will it effect the emissions when i nct [mot]the car.
thanks in advance and have a peaceful christmas and new year.GREG
