A sure sign of a blown turbo is loads of black smoke coming out the exhaust. Did the sound of the engine change at all? I ask this because one of the hoses might've popped off somewhere. Have a look under the bonnet for any loose or split hoses/pipes, starting from the air filter right the way to the inlet manifold. If the turbo is easily accessible then it might be worth taking the intake hose off the turbo and checking if there's any oil sitting around the blades or if there's any play in the shaft.

You might be lucky, it could be a loose hose but have a good look around and be 100% sure it's not before you take it to a garage and say your turbo's blown, you might save yourself a fortune.

Martys advice is good,and also have a look at the intercooler,they have a habit of splitting.

If it is the turbo itself,then avoid driving it.What will happen is it will start sucking engine oil out of the sump and the engine will rev up to 100,000 rpm and you won't be able to switch it off!.It's quite a frightening experience,I can tell you!

Good luck and let us know how you get on.:)

Intercooler

My Laguna makes a whooshing noise and I have just been diagnosed with a split intercooler - but she still drives even if its got as much go as a deceased rabbit? Power pogo's as it hits 2k then behaves like a 50cc scooter!!!!!!!!

It could be something rattling around in the cat, or if you've got a lambda sensor it might be the casing moving about, I've had that before, nothing to worry about.

Could also be the heat sheild, I think it runs the entire length, I've had issues nrear the back-box and had to bend it up out of the way - sounds like tin rattling - I noticed it more shutting the boot, didn't take a minute to find and sort out. :)
