Whistling when accelerating outlander turbo diesel


turbo whistle is common as it comes from the tips of the compressor wheel passing through the sound barrier and the turbulence occurs. IN the older trucks you would the turbo whistle as the engine reached full RPM just before a gear change. In smaller engine it is not do noticeable as there is an excess of air pressure that keeps the compressor wheel at a lower rpm and the pressure is dumped out. Turbo compressors reach revolutions in excess of 120.000 rpm under full load If it has just started to make the noise then check the intercooler system for leaks--loose clamps--- splits - Have the turbo compressor checked for damaged fins from the ingress of fine dirt from a bad air filter---check the air filter is not blocked as the turbo speed may result from running in a partial vacuum ( no load on the compressor wheel)

Nissan Navara STR 2006 d22 3lt turbo. Turbo is whistling very


Remember, what is heard as turbocharger noise may not be caused by a noisy turbocharger. Before replacing a turbocharger perform the following diagnosis.
A. If a loud whine or whistle is heard during acceleration and increases or decreases with rpm and load. This condition is most often the result of a loose clamp/hose at the turbocharger compressor outlet, charge air cooler inlet, outlet or at the intake manifold.

1. With the engine running at idle and the transmission in Park or Neutral with the parking brake set, feel for boost air escaping at each connection between the turbocharger compressor outlet and intake manifold. For limited access areas, spray soapy water on those connectors and look for bubbles.

2. Check the exhaust manifold and exhaust system for leaks.

I hope this helped.

Thank you,
Norse

WHISTLING BELOW TURBO


Its surely not turbo, its is somewhere a hole or leak in turbo air filter housing or air inlet pipe that is making noises when turbo sucks air. check the air pipes wheather they are fitted correctly. Take a keen look at air hose and close any hole with silver tape check the hose is fitted correctly in Turbo air filter housing (if not then it makes whistling noise when air is being sucked by turbo) . Clean all air filters and then give it a go.

Whistleing sound on golf gt tdi


It's probably the turbo you're hearing. They spin very fast and make a noise like that. Ever hear an 18-wheeler go by you and accelerate and they make that high-pitched whistle? That's the turbo spooling up. Now, if it sounds like a dentist's drill, that's usually a sign that the turbo is failing, but I'd bet that since your car is under four years old, as long as you've kept up on the maintenance, it's the normal turbo spool.
