I've noticed that when going down the gears, as the revs fall to 2500 there's a bit of a rattle.

I'm assuming that its the turbo slowing down, with back pressure? and its making it rattle.

Is this normal?

If not, do I need a new turbo or could it be something else?

Erm, the turbo wouldn't rattle...
What MY is it? Most likely to be that the up-pipe's or header's 'cover' has cracked (not uncommon). Depending on your ECU, the fuelling will switch at around the 2500rpm point when revs are dropping, which could I suppose cause a bit of a shake, which might be at just the right frequency to rattle one of these?
But I may be completely wrong I'd be suprised if it were the turbo, though!

Hi nom,

Thanks for the quick reply

It's a MY99 UK

Glad its probably not the turbo (could of been expensive)

I've just done a search (didn't think it was working, but it seems to be now) and looking through the tread results it could possibly be the heat shield?

Yep - heat shield's another one! Forgot about that

The turbo would not rattle as you say. If the turbo impeller was loose in the compressor housing you would only hear a very hight pitched wine until seizure. Sounds like something ancillary to me probably the heat shield as said or something else like a flexible cable or something. Do a bit of troubleshooting if I were you.
