Thanks guys.

As I was up near Inverness when the car broke down, I have left it with a mechanic up there. (Reccommend garage from a friend).

I am still waiting to hear from them what the damage is....so fingers crossed.

In the meantime, I have a 3cyl 1.0l fiesta turbo on hire for the week, and its a fantastic yoke. fast and smooth!

Swirl flaps are little butterfly valves within the inlet manifold. I know these were a problem in older model 3 series, but not sure about the F30 series...
What happens to the swirl flaps is they can get clogged with gunk, and/or break apart whereby the bits can fall into the cylinder causing major damage.


Is there a procedure on how to remove the inlet manifold? And EGR cooler?

Just heard back from the mechanic...
EGR cooler is blocked, which caused the inlet manifold to heat up and melt.

New EGR cooler + valve, inlet manifold, MAP sensor & gaskets.
£1100 on parts
4.5hours on labour.

Going ahead with the fix.
Next question is should I sell it? or is it safe to keep....

The N47tu/N57 has swirl flaps, but they are of a different design than on m47/m57. It looks more robust.
