Does it happen with engine off, running or just when you`re driving and does it stop if you turn the heater off? (mine`s never whistled at me but then I`m old and rough as a bears a**e)

happens intermittantly whilst driving takes a while to start whistling maybe after 5 10 mins driving but once started does not stop not investigated turning off blower seems to come from the left of the car louder when i open the window wide as if it is coming from the wheel ? thats why i thought wheel bearing but not too many miles on the clock so unsure ? ( not even sure if wheel bearing makes a whistle or a bang ?)

If it takes a while to start it sounds more like a mechanical problem. You could be right about the bearings but I`d wait for one of the more mechanically expert to give an opinion. (it doesn`t take much to be more mechanically expert than me)

Hi there Sarah. In my opinion, if you can hear the noise get louder when you open the window, then I could only conclude that it originates from outside the car (so I wouldn't think its the heater/fan). The type of sound you are describing, and the fact that its not present upon first setting off, but once it starts - its constant, would lead me to believe that there is some dry contact occuring. Two main questions;
1. Does it vary with speed (i.e. get louder / higher pitched) as the car's speed increases? If yes, then that would indicate that the sound is originating from the wheel area - could be bearings, or even a high-spot on a brake disc making contact with the pad.
2. If possible, try to drive (once the sound is present) at a constant speed, then change down/up a gear without changing speed - does the sound change? If it does, then that would indicate something under the bonnet (slipping drive belt, the bearings in a pump, for example) is giving rise to this.

What I'm trying to do is eliminate some possibilities, and narrow the field.

Hope some of this helps you.

Paul:)

Yep,I'd agree....

Sounds as though there is a problem with the rear brakes.If it stops when you put your foot on the brake,then it could a dust build up or something rubbing.I'd get it checked asap.:)

More likely to happen to drums than to disks. Does yours have drums at rear? Easy to find out... apply your handbrake as you drive and if it (the whistle not the car) stops, it's rear brakes.

Nah! Just checked on t'Internet and it says they have discs. Try the handbrake test though.

Hi sarahswregscenic

From reading through the thread the whistle is the brakes rubbing at the back,this can happen even with new pads fitted (as we found out on our scenic).

The cure on ours was to dismantle the rear brakes,clean and reassemble,then check the action to ensure brakes release.The calipers themselves have two sliding pins which if siezed will cause your problem these pins need to slide to allow the pads to release the disc.

My advice is to get a good mechanic to dismantle the brakes and clean sliding pins on the calipers.

Hope this helps.

:) :)

When the whistling starts again, lift the bonnet and check the noise isn`t coming from the belts on the engine. You might need to rev the engine a bit (Go to another garage and get another opinion on your brakes although the figures don`t seem to bad).
