Put a tube in your ear and wave the other end around until the noise is loudest. A vacuum cleaner tube does work.

My ETB's make a similar noise but not as high pitched or as loud.

To me it sounds like some sort of alarm.

Something in fuel tank system, like an air inlet valve, or one on an emissions system canister?
Second thought, an air conditioning valve, heard similar on heatpumps with stuck reversing valves.

I reckon #7 is the winner.
Where the F is the off switch ๐Ÿ™‰

12 nop take a better guess lol

gpg58, Jan 20, 3:20pm
3rd thought, brake system - Vacuum Inlet Check Valve, or booster diaphragm leaking?

#10? ๐ŸŽง
Air conditioning valve?
That noise is worse than fingernails down the blackboard, Iโ€™m not pushing play again but I feel like Iโ€™ve heard it before. ๐Ÿฅด

I think you may be right - we didn't do anything to try and correct it though - the car was in for something else.

Donโ€™t tell anyone but I have no idea of what it is you are talking about but Iโ€™ll remember what it sounds like ! ๐Ÿคฃ

Thanks for the fun ๐Ÿ˜„
