21583563-2A / SW9665799180 – Engine ECU J34P Peugeot Citroën | VIRGIN / IMMO OFF

The offered engine ECU with numbers 21583563-2A and SW9665799180 is an original Magneti Marelli J34P module used in Peugeot and Citroën vehicles equipped with 1.4 and 1.6 petrol engines. It is a factory unit found in popular models such as Peugeot 206, 207, 307, 1007 and Citroën C2, C3, C4.

The ECU is available in two preparation versions:

  • VIRGIN – fully cleared, ready for coding and adaptation just like a new service unit,
  • IMMO OFF – immobilizer disabled, ready to start immediately without BSI pairing.

Each unit has been tested on a professional bench, fully functional and ready for installation. The IMMO OFF version eliminates immobilizer or BSI communication issues, especially in older vehicles.

FAQ – Frequently Asked Questions

Which models are compatible with ECU 21583563-2A / 9665799180?

This ECU is used in Peugeot and Citroën vehicles with 1.4 16V and 1.6 16V petrol engines, including Peugeot 206, 207, 307, 1007 and Citroën C2, C3, C4. Always compare your ECU number to be certain.

What is the difference between VIRGIN and IMMO OFF?

VIRGIN version behaves like a brand-new ECU — after installation it requires BSI and key adaptation. IMMO OFF has the immobilizer disabled and works immediately without pairing to the BSI.

How to program the J34P ECU?

The Magneti Marelli J34P ECU can be programmed using diagnostic tools such as Lexia / DiagBox, Launch X431, Autel, or ECU programmers like KESS, KTAG, MPPS.

Can I install the ECU myself?

Yes. Installation is simple. For IMMO OFF no configuration is required — the ECU works immediately. For VIRGIN you will need adaptation using DiagBox or Lexia.

Is the ECU tested and covered by warranty?

Yes. Each ECU is tested before sale and comes with a 6-month warranty. Warranty applies if seals are intact and the unit has not been opened.
