Rattling Sound From Boot Area When Pumped Full Tank

[Firestorm 0]

I have this rattling sound from the boot area for quite some time already. its very irritating and it will come on when i go pass uneven road, humps etc... and i realise the sound comes from slightly different locations at different times.

I adjusted and tightened almost everything, stuffed papers n tshirts on the top of the boot area etc but cant solve the problem.

 

 

then i realised that when my petrol is abt less than half full, this rattling sound will disappear.

anyone know why is it like this? any experience pls?

 

thank you!

What car?

I'm thinking anti roll bar bushes.

 

 

But what type of noise is it and is this a sportwagon or saloon?

its a 159 saloon.

the rattling sound is something lie metal hitting agst each other, when car goes over uneven road, there will be like "dit dit dit" or"dit dit dit dit" sound...

loose heatshield or ARB bushes I'd say.

so loose hearshield or ARB bushes can be affected by amt of fuel in tank to make the rattling noise.

 

many worshops do not want to troubleshoot my prob bcos they say is too time consuming and may end up with no fault found.. sighs...

Plastic tanks sag when full so they can press on heatsields, and the more fuel in the tank the more weight in the back so the position of the ARB bushes is slightly more rotated, without the car it's guesswork based on previous issues I've solved
