Year of Manufacture *: 2007
Engine Code or CC *: 1.9
I'm not overly familiar with newish Renault and especially diesel but found the sound to come from what appears to be an electrically actuated EGR valve. I pulled plug on and off to confirm this was the source.
Owner hasn't noticed any other problems and no Engine Check Light.
I just wanted a bit of a heads up as to if this is a common problem, checked UKAT archive and no reference to buzzing but some driveability issues which I dont have.
Maybe they partially jam and the ECU is trying to move it to a post run/pre start position? Noise stops after about 15 secs or so.
Car comming back in a couple of days for a proper look.
