I really don't know where to post this.
My vehicle is a 2009 Nissan Navara D40, 6 speed manual 4WD 4Dr 2.5 diesel.
please bear with as I'm going to describe a noise that my local Nissan dealer can't diagnose.
We both agree on the existence of this noise - but what it is as yet is unexplained; they are now sending the vehicle to Bangkok for their "engineers" to sort out.
However I'd like some input form outside Nissan as to what it might be - I don't want Nissan to come back and tell me there is nothing they can do......I think they might be playing for time here or even trying to avoid costly work whilst under warranty.
So here goes......
essentially there is a "ticking" sound. This runs in sync with the engine and is only audible when the throttle is depressed - to any extent big or small.
Under hard acceleration the ticking becomes louder and with the pedal to the floor a rather disturbing "thwacking" sound occurs. This sound is strongest under acceleration with your foot right down especially in 5th gear. (I'm not even 100% sure the 2 noises are related or emanating form the same source).
My local dealer's service dept has made several attempts - in vain - to eradicate the sound, finally announcing they couldn't do it and are sending the car to Bkk for 3 days.
The mechanics who have test driven it with me seem to be convinced it is a clutch problem - I'm not 100% convinced and think it might be injector/common-rail or even turbo.
If you have any ideas, I'd be most grateful as I'd like to be in a position to make an educated assessment of Nissans diagnosis when it comes in a couple of days.
Look forward to hearing your suggestions.
