Odd Rattling from 2.5k revs up to 4k revs

[Lukas1]

I have had this problem for a month now and put it down to cheap Renault materials and but it had got progressively louder and when i give it some to get on the m'way it rattles even louder. Sounds like it is coming from behind the centre console and its truly bugging me, only seems to crop up when i put my foot on the accelerator sightly and also when i take it off the accelerator.

Any ideas guys?

Thanks
