BMW swirl flap blanks
BMW diesel engines produced between 2000 and 2008 have a particular design problem with inlet manifold swirl flaps. Swirl flaps are used inside the inlet manifold of the BMW M47TU & M57TU diesel engines to vary the length of inlet manifold tract subject to load and anticipated demand. This allows optimum performance to be delivered. BMW swirl flaps commonly fail in such a way that they either drop a screw and/or the upper section of the spindle. This can do major damage to the engine, The outcome of such failure is not pretty in the slightest. A metal piece fallen off the butterfly flap will be slammed by the moving internal components. Most often one or more piston ends up being severely damaged along with valves, an injector and the cylinder head, with possible damage spreading to the turbo as well!
