DOES ANYONE HAVE ANY IDEAS ON THIS ONE....I WAS DRIVING THE OTHER NIGHT WHEN SUDDENLY I GOT THIS WEIRD NOISE ..IT COMES IN WHEN THE TURBO IS ABOUT 0.5BAR BOOST WHEN ACCELERATING ..THE CAR DOESN'T SEEM TO BE LOOSING ANY PERFORMANCE ..IT SOUNDS LIKE IT COULD BE THE TURBO ...HAS ANYBODY HAD THIS OR KNOW WHAT COULD BE WRONG?????

Does it sound like a metalic rattle and have you got a de-cat exhaust?

Does it sound like someone blowing accross a bottle top? If so then no panic, you are just leaking boost and a new DV is cheap and easy to fit.

IT DOES SOUND LIKE A METALLIC RATTLE AND YES I HAVE A DE-CAT EXHAUST!

It does it on mine, I asked the question a few weeks ago and got the response something along the lines of...

It's exhaust gas escaping between the turbo and DP joint beacause of the seal.

yeah, the metallic rattle is sometimes the gasket fluttering at the turbo flange, try replacing it.

;)

Think it was someone from scoobymania that gave that answer. Only started when I addded the HKS Downpipe. Like you I thought it was the turbo, I've done nothing about it yet but I guess I'll stick some exhaust seal between the DP and turbo when I get the chance.

It was me that fitted the DP and I know for a fact there is no gasket between it and the turbo.

Can't see how it could cause any damage.

ah, dunno if you havent even got a gasket :confused:

maybe just gas escape then

I think it would do it when the DP heats up because I have no seal between the DP and turbo, heat would expand the metal and could create a gap and the whole joint could move hence rattle.

I HAVE HAD THE DOWNPIPE FOR A WHILE AND IT HAS JUST HAPPENED ..AFTER A BLAST...HOW DO I SORT IT .I WAS GOING TO TAKE IT TO THE DEALER .IT DOES SOUND LIKE SOME SORT OF LEAK .
