Description
Part number 21584180-6, also catalogued as 84820V02, is an original Sagem engine management unit for Citroën and Peugeot models built on the shared PSA platform. Sagem supplied engine control units to PSA across a broad production period, and this unit was specified for a defined engine and calibration variant within that range.
Removed from a vehicle confirmed in active service, this ECU has been bench‑tested to validate all primary management functions. Connector condition and housing integrity are checked before the part is packaged for delivery.
A Sagem OEM control unit holds the factory fuel and ignition calibration specific to the PSA application it was built for. Using an original part ensures the engine operates precisely to its design parameters, preserving the performance and economy characteristics the powertrain was engineered to deliver.
Quote either 21584180-6 or 84820V02 when ordering to confirm suitability for your Citroën or Peugeot. Our team can advise on application‑specific fitment before purchase.

No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
