Your engine can be damaged by one of the original BMW swirl flaps in your manifold failing & being sucked into the combustion chamber! This is a significant & well known problem for BMW diesel owners with stories of £8000 engine replacements being required in some cases!
But don’t despair, Iridium can help you get rid of this potential time-bomb with our professional swirl-flap removal service.....
BMW engines affected by swirl flap failures include:
Diesel BMW's feature swirl flaps in the intake manifold to aid air-fuel mixing at low engine speeds. However, these flaps are known to come loose & can be sucked into the engine causing extreme, & in some cases terminal engine failure.
We remove the entire intake manifold, remove the standard swirl flaps, clean & replace with our aluminium-alloy CNC- machined viton-sealed blanks before reassembly. This has a negligible, often-unnoticeable effect on performance or economy but totally removes the possibility of expensive engine damage through flap or screw ingestion.
