Thread: A whine D3

The top hose splitting underneath seems to be a common problem as the hoses get older.

adzee - if you do find a split or other damage to the intercooler hose, a suggestion: replace it with a silicone hose. Like this one:

Good luck with the fix, I have a similar whine in my D3, I am assuming it is not the same issue as I have no extra black smoke, fuel consumption or boost/power loss.

It is a high pitched whine, and it comes and goes with acceleration, pretty much from boost rpm's upwards to where the boost curve flattens.

The issue is turbo related:
It seems to be either slight damage with the veins in the compressor housing or it could be a sticking waste-gate actuator.

I will also check my I/C hoses, but pretty sure they are ok as I did check them briefly on Saturday during the alternator install.

Thanks all for your help in potential symptoms.


The noise I have been hearing apparently isn't the hose... I couldn't see any damage/holes or splits and so took it to a local land rover specialist.

They took it for a spin and think it may be an idle or belt tensioner. So it's booked in for Thursday. Hoping its that.

Apparently I am a bit sensitive to it, and there was no visible smoke so it pretty much ruled out the hose.

Will keep you all posted, and if I intend on keeping the vehicle I may end up replacing the hose.

Cheers

No wastegate on these turbos.

Ah oh dear, then my whine is a worn turbo bearing or compressor wheel?..

Might want to research this possible problem: - I was thinking it was waste-gate, but they are non gated turbos, diesel style.

-The arm for the variable vein actuator on the turbo. These can get rusty and stick open, also a build up of carbon can cause the issue. The issue is boost comes on pretty hard around 2000rpm and you getting a pretty decent whine from passenger side front throughout the boost curve

Looks like this is the issue with mine

Ok so I got mine back today and it was the idle tensioner, had it replaced and checked over, along with a few other assessments and all is good, $380.

Glad it wasn't the trans, and at least I know about the turbo hose.

Now for the next couple of things to sort.., tax back better be good! Haha
