BMW 520D SWIRL FLAPS.........???
With many modern day direct injection engines, it is very common for carbon build up to accumulate in the inlet manifold & cylinder head ports.
Due to the EGR recirculating the exhaust gases back into the inlet to reduce the emissions, soot particles are also entering the inlet and with the engine breather system the oil vapours cling onto the inlet manifold allowing this soot to accumulate.
Over a period of time, the carbon build up becomes excessive causing restrictions to air flow and also causing resistance to the swirl flaps & its actuator. This results in failure of the swirl flaps which can cause catastrophic engine failure on certain engines.
In this FYI, we show a BMW inlet manifold that was subject to the carbon build up in which the swirl flaps & actuator had failed excessively causing a boost leak from the actuator side and also becoming disconnected.
Lucky enough for the client it was diagnosed & repaired straight away. If left any longer the swirl flaps could have broken and entered the inlet.
Repair carried out was to replace the inlet with a new Genuine BMW part!
