Description
MAGNETI MARELLI injection control unit FAP particulate filter
The FAP control unit EAS300.01 is a specialized electronic module designed to control the particulate filter system (FAP) in Citroën and Peugeot cars. They take care of the correct function of the additive injection and the regeneration of the filter so that there is an optimal combustion of soot and a reduction of emissions. With a properly functioning FAP control unit, engine performance remains stable and the risk of emergency mode, excessive smoke or error messages on the on-board computer is reduced.
This part is suitable for professional auto mechanics as well as skilled home repairers who are looking for an exact replacement according to the unit code to keep the emissions system working properly and avoid expensive engine or exhaust repairs.

Typical symptoms of a faulty FAP control unit may include frequent illumination of the check engine light, errors in the additive system, the inability to regenerate the particulate filter, increased smoke or the engine going into emergency mode. Replacing the unit with a properly functioning one can, in most cases, eliminate errors related to mismanagement of the FAP system, promote a longer diesel particulate filter life, and ensure smoother engine operation.
Installation recommendations:
– Before removing the old unit, disconnect the vehicle battery to avoid damage to the electrical equipment.
– Check the condition of the wiring and connectors, possible oxidation or mechanical damage can cause errors even with the functional unit.
– Install the unit in the original holder so that it is protected against vibration, moisture and heat according to the original solution of the manufacturer.
– In many cases, after replacement, diagnosis and adaptation/programming of the control unit with appropriate diagnostic equipment is necessary so that it communicates correctly with the rest of the vehicle’s electronics.
– After installation, perform a test drive and check error codes to ensure that the FAP and additive system is fully functional.
