Hey all,
Thought I'd start a thread so I can try get some advice or where to start.

Came out of a junction, loud bang backfire at the exhaust, loads of thick black smoke and loss of power.

Taken for another small drive, and no further bangs, but loads of black smoke when accelerating, and struggling to get above 30-40.

No errors on the dash at all.

... where do I start to look to diagnose? / how much is this going to cost [/i]

Sussed it, intercooler/boost pipe has a big rip in it.

Amy recommendations for quickest place to get one delivered and part number?

Have a look here.

Change both sides as if one has gone, the other won't be far behind...
