I have a 2006 megane sport turbo and it suffers from a terrible rough idle especially when the car is on a slight incline, what could cause this
Renault said it was leaking injectors and replaced them and this made no difference at all
Hi there hope i can be of assistance.
Did Renault carry out any diagnostics one the car?Did they get any fualt codes?
Also, what elese did they fit to the vehicle, i.le fuel filter, air filter anything like that?
