My first post
I have a 2006 2.2DCi X-Trail with 109000 miles on it. It has a strange raspy rattle on the engine especially when cold but is intermittant and there when at temp also, both at idle and when driving and can make the noise at any rev speed. It sounds like a heavy whirring noise, sounds like a damn tractor! and as I said it comes and goes.
Any ideas ?
By the way the car runs smooth, turbo pulls well and zero smoke so I am hoping its a vibration more than an internal thing.
