Hi all,
I have got a wrx n reg and I have a rattle noise from the turbo area. It sounds like a heat shield but all seems secure? Any ideas or anyone else got/has this[/QUOTE]

It usually is the heat shield, whip it off and recheck

Yep, same as Matt said, they are prone to rattle, annoying things!

Its normally the heatshield covering the downpipe from the turbo, its there to stop the brake cylinder from getting too hot i think (could be totally wrong, as i am no mechanic). I think it has two skins to it, sometimes it comes lose and rattles.

Cheers will have a look later. My down pipe is a decat and has no heat shield

Could it be a bracket from the decat fouling on something?

PJB1

It sounds like its inside turbo

Does it sound more like a scratching on idle then increase with higher revs? I only ask as I've just removed a turbo that's knackered and that sounded like a scratching, metal on metal. Failing that it would be a case of trying to tighten up anything that may have worked loose, I'm sure somebody will be along to advise you further

Had Duncan from race dynamics this afternoon sorting mapping and he said its heat shield.
