This is a follow up to Thread 56399 started by Pepper 2. My 2005 3 Litre Diesel has developed a whistle which I can only detect at low speed. Pepper 2, how loud was the whistle in your engine and at what speed? Motor has only 42,000kms on the clock (owned since new) and the last couple of trips on the open road seems to have lacked power and would not kickdown when driving at 80 kmh. Recent service by ARB found nothing wrong, I did not mention whistle just that it would not kickdown.

I had a leaking EGR gasket which sounded like a whistle (or squealing belt) at low speeds, it's fairly common. I didn't jave the lack of kickdown symptom that you describe though.

David,
As said by Patrol man. It sounds like a leaking gasket.
It could be anywhere on the EGR track from the exhaust to the inlet on the manifold. I found mine was on the vertical tube from the EGR valve to the inlet manifold. This tube tends to warp. I just applied some exhaust gasket goo and fixed the problem.

Mine was in nissan dealership about 8 days they could not solve the whistle removed turbo,intercooler,egr pipe etc put it back together still whistles quite loudly.Also had major lack of power this was rectified by changing meter assembly -air flow sensor.Seems to whistle more on acceleration than overrun,

Hi David,
I had this issue resolved by Nissan delaer under warranty. In my case it was blown gasket between exhaust manifold and turbo.

The most common problem is the pipe from the EGR valve to the inlet manifold is alloy and it warps where it bolts onto the EGR. Remove the pipe and sand it flat with a piece of wet and dry placed on a sheet of glass. Refit with some new gaskets or silicone and it should be fixed.
