Had engine and gearbox changed on 06 plate. When the car hits 3k revs it's makes like a vibrating noise but only when driving, doesn't do it when stationary and doesn't change based on gear. Had people look at it and they've said noise could be coming from anywhere but more likely to be engine side. Don't want to get loads of things changed for it still to be there.
Anyone had similar issue? Thanks
