Car Engine Sounds Like Police Siren In The Distance

[elhayes]

I have a 2 litre 08 plate diesel tdci galaxy. It has done 50k miles. Whilst driving it around France recently, I kept hearing a sound like a police or ambulance siren in the distance. I then realised it was the car making the noise. The noise gets louder or quieter depending on whether I am accelerating or not. I took the car to our local garage, who simply said they did not know what the noise was . the car seems to be running fine generally. can anyone please help with a diagnosis? thank you.

Try posting in the MKIII Forum, as MKIII's are completely different beasts to the MKI and MKII's

 

 

DONE.

turbo?

look to see if any pipes have come adrift.

It might just be the turbo. I had a Saab 9-5 diesel and the (very quiet) while from the turbo sounded just like a distant siren. I've not noticed any turbo noise from the Galaxy.

Our mk3 Galaxy (56 plate 2.0 TDCi) does this too.

 

Is it indicative of imminent turbo issues?  :mellow:

could be?but from what ive read it could take a very long time before it goes,my smax does this.

might also be a hole in 1 of the pipes?.

Our mk3 Galaxy made it to Brussells & back this weekend, full load & sustained 130kmh for durations we can only dream of in the UK (unless you are nocturnal). No smoke, no problems whatsoever.

I'll keep an ear out on that turbo whistle, but for now I feel that there's no real problem.

...same again last weekend - London > Pembroke Dock (SW Wales) > London (total approx 600 miles), fully loaded up... not a problem. 

Will need new tyres & I'll get the tracking done too...
