More flameage
I went to the cinema last night, and for whatever reason I decided to take the 'teg, just though I'd give it a run. It was running flawlessly, got to the cinema without any issues, parked up and noticed a little wisp of smoke come from under the bonnet.
I popped the bonnet, and the smoke was coming from around the manifold/turbo/downpipe area. Then before my eyes said area burst into flames
So I got my fire extinguisher out of the car, pulled the safety tab, and the top of it fell apart in my hands

, I then ran into a nearby restaurant and grabbed a fire extinguisher, came back to the car and the fire had all but put itself out, I extinguished the small flame that was still burning. Thankfully there is no damage whatsoever, aside from the downpipe/dumptube heatwrap being a little scorched.
The only explantation I can think of is the turbo feed was weeping oil again, it soaked into the heatwrap, then when I stopped the heat built up and ignited the oil.
