oh dear,
The problem is also that assuming this is not an issue with MY07, IMO the jungle drums will sound and the (misplaced) assumption will be that all cars pre MY07 have an issue even though it is MY06 specific
To be honest it does say it is a MY06 specific problem, but i am a little worried as the GT4 had the 300ps engine. Personally i think Nissan know there a problem with this engine, hence the new engine in the MY07.
