Have been to another dealer....
Couldn't find any issue on the ramp, when rather than assuming I am another tosser of a customer, we went out for a road test and found the noise.
It is coming from the rear off side spring and wishbone!! So it is booked in, and the dealer are goin to keep the car until it is fixed...
I also asked to show the service manager the corroding wheels, but he said he had already seen them, its a common problem, and they will get it sorted out! He did say there would be no issue getting it sorted, which is good news, but also added that it would be MY wheels getting refurbed, not another random set. Apparently the first car they ever had a problem with was a GT4, and Nissan put a stop on fitting new wheels, and only supply refurbs... at least therefurbs will be mine, so I know what is going back on!
Thought you guys would find that useful info....
I must also recommend Coventry dealer too... very good indeed. Even bought me a coffee!
