Hello - this "intake swirl runner" problem may require removal, and repair or possibly replacement, of the intake manifold. The "swirl flaps" are internal to the intake manifold, and work to keep air velocity high during low speed operation for better performance and fuel economy. Since your engine is turbo-charged, the intake manifold often has positive pressure on it, which results in the outward flow of air and soot you have noticed. It may be possible to repair this problem by replacing the intake manifold runner control. This can be done by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
