Hi there, really need some help on what this sound is there is obviously something wrong there was no sound from outside the car only the in side. in the video there are some loose coins and a lightbulb I have taken them out and it sounds the same, so it’s not them if anyone has a guest or theory please let me know thanks you.

Suggest you check your polybelt, as may be disintegrating belt.

Remove the carpet on the rear bulkhead behind seats and undo the metal cover and you should see the belt, alternator, water pump, etc and hopefully the source will then be clear.

There's lots of online guides and videos showing you how.

Hope this helps.

That is an unusual noise on any engine I think.
Good idea about the belt above, but the engine will be well exposed with the inside cover off so if not the belt, the culprit could be more obvious.

As above check the belt first sounds more rubber related than metallic.
Good luck with the fix

Hi William,

That really is a weird sound!

In addition to the front cover you may want to remove the top cover to get access to the induction system as well. It does sound rather “reedy”, so maybe something’s flapping around internally there?
