My doblo has started a loud winning sound when revved ...help please

A winning sound, eh?

Sorry, likely whining, but I knew what you meant.

I would imagine turbo is about to expire if it is a "whooooo" sort of noise.

But it may be a leaking hose from the intercooler, it is a known issue on the 1.9 jtd as the hose can get worn through near the gearbox.

....or it could be a clutch release bearing

The trouble with trying to diagnose online with so little information is it's like doing the lottery. Some days you win, some days you dont

What year, what servicing and so on

Hi its an 04 plate and please excuse my ignorance but Im not sure it here a turbo as for servicing only had the car for just over a month so not sure

The problem with a whining sound is it could be absolutely anything from an alternator bearing to a failing fuel pump or even a loose belt!

At 10 years old I should imagine it could be any of the above....

Can you video it and post it?

Is it anything like this sound? :

Yooj

That sounds too much like a bearing whine to be a turbo whine.

The fact it keeps up with engine speed, as opposed to later, which would suggest turbo. So I don't "think" it's a turbo....

Does it make any difference if you press the clutch? If so, start with the release bearing. If not, it's likely to be a front engine noise.

My guess is THAT whine is a bearing. I would first disconnect the alternator belt to see if it goes. If it doesn't, I would then be checking the timing belt idler & tensioner bearings.

Last thing would be PAS pump, but it doesn't sound too much like that.

Hi guys my problem was the turbo ,had it replaced now all good

Well blow me! (you see what I did there? )

Seems whining has different frequencies then!

Trouble with whining is, so many different types....like when we were driving a rented Clio up Mt Tede in Tenerife. I could hear a whine that turned into a screech

Turned out it was my wife

Just out of interest how much was turbo.
