hi, i have a code coming up on carly 004501 which as far as I can learn is Exhaust gas recirculation control deviation? does anybody know what to do or check to fix this as its bringing up an EML and I need an MOT. I have cleaned the EGR valve , the MAP sensor, and fitted a new modified crank case breather so I don't quite know what to look for next. thanks Paneuro.
