The problem with trying to diagnose a noise is that you need to drive the car to be sure what the problem is/might be.
My van had an exhaust leak that made the turbo sound like it was noisy, I didn't actually say the problem with this car was the exhaust leaking.
You will get a turbo whistle with a split intercooler pipe as well, but it may be down on power as well.
As I mentioned earlier, my neighbour's car had a turbo failure after the turbo started whistling, but it doesn't always mean the turbo will fail.....I had a Citroen Xantia for 3 years that whistled every day from when I bought it to when I sold it....60,000 miles later. |
