Hi guys, when blipping the throttle when in neutral just before it settles I get a rattle, coming from beneath the turbo, nothing obvious ie heat shields, any ideas? Thanks gal.

Still a catted up pipe?

Could be anything, do it with the clutch depressed, could be the release bearing.

Heatshield is also possible, loose exhaust bolts, intercooler bolts, fecked turbo lol

Get underneath and get someone to replicate it for you

Also a good call, the cats disintegrate and eject themselves in some cases, not recommended lol

Still catted up yes and sounds like it's coming from it!

A probable cause, watch it does collapse and travell upwards lol

Holding a screwdriver to my ear the noise is coming from the part behind the turbo with the heat shield round it

Try and get a video up to help diagnose, the noise could be travelling up the up pipe and be heard in turbine housing

gal001

Is it the first cat just behind the turbine housing i assume? Have narrowed it down to there now i have a extra pair of feet for the throttle lol! Would it defy gravity and break my turbo then? Now worried as have a 300 mile round trip in the morning!

If in doubt flat out?

The first cat is below the turbo, does it buzz when holdin revs steady at a certain point? Can the sound be traced to the turbo cartridge?

gal001

Noise is at the bottom of the cat where it meets down pipe, no buzzing, sounds like there is a nut bouncing around inside best way of describing!

Least its not to do with turbo lol has it got any worse lately? Is it standard downpipe?

gal001

Standard down pipe noise been there for a few days but got no worse, though when car idles at 800rpm it's constant, normally sits at around 5-600

Sound internal to the exhaust, have you checked the bolt that holds the downpipe on the underside? Personally if it was me i would rip the downpipe off after the journey ( when its cold lol ) and inspect it as i know how annoying rattling can be!

gal001

Bolt tight, will just take it easy tomorrow and rip the bugger off Sunday! Thanks for your help guys
