Anyone give me a clue what a faint whistling noise from the engine bay might be? It's a bit like a turbo noise but obviously there isn't a turbo and it out the same way it came in.

also speedo cables is there a way of making sure they are connected to the back of the speedo?... mines looking a bit drunken.

Whistling noise? where in the engine bay is it comming from??

Could be a bearing, alt belt or alt bearing, gearbox, lot's of things really.

The speedo is normally down to the gearbox side but the dash is easy to get to to find out if it's attached properly. They do wear which can cause the fluctuations as your driving

sorry to bring up an old thread, but my panda is now whistling/hissing when i accelerate (sp), its got quite bad, and sounds like a turbo. When i drive down the high street people now look at the car due to the noise (turbo charged panda ).

Check the exhaust isn't blocked with the fibreglass type material in the back box, it can clog the exhaust if the baffles collapse and sounds like a high pressure hiss when you accelerate.

i hope its not the back box, as it was only done in july

It will still be under waranty then?

if i can find the receipt

Have someone accelerate the car whilst your behind it and see first.

Thanks for the advice Alan, i just hope its nothing to do with the selecta box

Let's hope it's the exhaust but If it's anything to do with the box check fluid, if not that what is the condition of the fluid and when was the screen filter last changed.

could be an air leak on your inlet manifold. Is it running well?

its sometimes running lumpy, and if i dont use the car for a day it judders when started.

Check the vacuum hoses on the inlet manifold side of the engine. Does the servo work ok? If it's not giving much assistance, check the hose from the inlet manifold to servo unit.

Also check the cambelt tensioner bearing. These can make weird intermittant whistling noises when they start to go.
