My dealer is still investigating like I suspected no fault codes logged.
They have it for another few days whilst they try and get it to do it. Interestingly there is a number of issues currently surrounding EGR valves.
To back it up everything about it being the EGR getting stuck for a few seconds seems possible considering my dealer admitted to me the N57 has had a number of EGR valve problems. Not related to carbon build up but lack of lubrication for the cam.
During that time I get the "pleasure" of driving a BMW 318d M Sport manual...can get it any worse!
