Whistle ???

[jobela]

Hello All,

Did someone experienced a whistle when accelerating? Specially on low revs? What could this mean?

 

[BlackC55]

What car?

Is it a diesel?

 

[jobela]

Yes, a c200cdi

 

[BlackC55]

Its probably just the turbo spooling up.

 

[jobela]

And that would be normal, yes?

 

[BlackC55]

Yes if it is that.

Take it to your nearest specialist or dealer and get them to have a listen just in case it is not that.

How long have you had the car, and has it always whistled at the same volume?

As BlackC55 pointed out whilstling is normal on a turbocharged car, but if it worsens it can suggest that there is a deeper problem.

My Rover 220 SDi sounded great, like a diesel loco - much better than our ML270 CDi.

On a lighter note, I find the quickest and easiest way to stop an annoying whistle, is to make the offender smile. Very difficult to whistle when you're smiling!!

 

[jobela]

No, it has been whistling more and more...

The exhaust blew on my diesel turbo but to be honest it wasn't immediately obvious but the turbo started to whistle at certain gear change points; new exhaust cured that upon investigation, but any turbo whistle which is new and progressing must be investigated

If it sounds like a ghost train it could be either the turbo on the way out or a hole appearing in the intake hose

 

[jobela]

Ok, thank you all for your contribution

I reckons Shauns hit the nail on the head, as you build up the revs the boost pressure builds and the leak becomes noisier.

I have had similiar on landrovers and has been the hose from the turbo to the intercooler, not to dear.

Need attention as it gets worse the turbo has no head of pressure to work against and can overspeed.

You cannot get the noise just by revving the engine it has to be pulling ie working.

Could it be an exhaust tone ?
