While we were travelling recently, and towing the Van I noticed that it has developed a whistle noise similar to a boiling kettle sound, it mainly did it when acceleratng under load,and when you take the foot of the go- pedal it would go away, it's a 2008 3ltr CRD, since we have returned home I have noticed the noise is there all the time when acceleratng, it doesn't whistle when idling, I was wondering if it could be a problem with the Turbo, I have booked it in at Nissan because it's still under warranty it's just turned over 20000 ks, yep it,s the Cooks shopping trolley lol.

Cheers

Hi Daza,
Your problem sounds very much like a split in one of the flexible hoses connecting the turbo to the intercooler or the intercooler to the inlet manifold.

Yeah, for what it's worth I'd go along with that. Sounds like turbo boost leaking from a hose or some connection which is why the noise is more noticable on acceleration when boost pressure is highest.

hi dazza
i would'nt worry to much
my safari turbo has whistled just like you describe since day one when i had it fitted after market at 52 th km's
and it's now done 138 th km's and still whistles while under acceleration there are no leaks or holes in anything as mentioned and i took it off last year and had it checked all a1 put it back on and it just continues to whistle and sounds good
whistles while it works and i have a boost guage and all is ok pressure wise

I think the difference might be that yours whistled from day one so probably a characteristic turbo sound while his has just learnt to whistle.
Maybe it will sing when it learns the words...............lol

The are well known, amongst other things, for getting pin-holes in the intercooler. Please get it looked at quickly, as loading it up too much whilst leaking boost could lead to higher than normal EGT's.

EGR valves have also been known to leak a little.

I just had a similar thing with the 100 series, I found out it was a simple inlet manifold leak, we tightened it up and all is good.

It could also happen if the exhaust manifold has a similar leak.

You could give it a new nickname Daza,
Polly, as in Polly put the kettle on.

I hope they find the culprit, It'd drive me insane, I hate noises, I've got a rattle somewhere in the back that I can't find, And No it's not empty Beer bottles,
I've cleaned them out.

Mine did the same a couple of weeks ago. It was a distorted return pipe from the EGR to head. A thicker gasket was the answer. The original gasket acted like a reed with the air passing over it.

Mine had the same noise under the same conditions. It turned out to be the pipe from the EGR had slightly separated from the flange. It took a year to find going back and forth to Nissan.The turbo was replaced and the pipe removed examined and replaced over this time before it was found. All under warranty.
After all that time the only telltale was a small amount of soot at one small area where the pipe goes into the flange. So! So! glad to have it fixed it was driving us crazy. Good Luck!!!
