Weird noise under hard acceleration.

[volvokid]

I have noticed a weird rattle sound when i floor it i think its from the engine. My mates 182 does it also, does anyone else hear it in there car and what is it???

On mine it was the exhaust sheild rattling as it had come loose

Where does the noise seem to come from?

Rattling and knocking noises are the Clio's forte. As people have asked, where is it coming from and how loud is it?

Mine still makes a knocking sound (although it's quieter than it us to be) when I accelerate hard even though I've tried various things to cure it.

It not crazy loud but very noticeable, it could be the exhaust but i don't think so, if you rev the car when its stopped you still hear it but you have to put the foot down before it does it.

Yeah my money is on the exhaust hitting the underside of the car if it's doing it when stationary, is it a metal on metal sound? Check the exhaust mounts, the rear ones are prone for wearing out.

yeh i have the same problem, i have an after market exhaust system and one of my mates told me it could be a loose bracket as they had the same problem, all he did was take it off and the rattle disapeared.

Not definitely saying it is this by the way, just the 1st thing I'd check.

Its just weird how my mates one does it as well thats why i thought it may be a common thing.

 

[Jonff]

Yeah it is fairly common due to the rear mounts being crap. Best thing to do do is waggle the backbox and check for excessive movement, or get under the car and get someone to rev it, you'll be able to see where it's hitting the heat shield underneath. If that's what the noise is obviously.
