Check engine light


The check engine light is telling the driver the computer has found a problem that will affect engine performance and emissions. The light is not a warning for mechanical problems.
You need to get the computer scanned for trouble codes to proceed with testing.

My 2007 Land Rover Freelander makes a whistling sound when vehicle is idling. Sound goes away when accelerating or applying petrol?


it may be a turbocharger if so equipted, lots of turbocharged cars whistle as the unit gets older..only other thing I can think of is something with the exhaust system.. get it looked at by putting the car up on a lift and inspecting it..now some cars also whistle thru the radio ..this is called alternator whine and is usually correected by a filter in the power line of the radio...good luck

2003 PT Cruiser turbo. Has just 67k miles on it. Just began making a low pitched loud whistle sound on acceleration or load/uphill. Gets louder with greater acceleration/load, no decrease in power.


I took my car to Keller's Auto Repair in Gettysburg PA, He specializes in Chryslers. I have 04 Cruiser with 2.4 Turbo that had the same whistle noise, and check engine light on. He found code P0301. The noise was caused by the #1 Cylinder injector O ring. Check them out on facebook. They will help you.

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 noise when accelerating


you most likely have an aftermarket radio installed
the noise you hear is engine noise, if yo turn your radio off it will go away
this can be fixed by either getting better wiring for your aftermarket radio or by installing a noise filter, you can purchase that at most big electronic stores
