Engine ECU 9666909780 / V29006828A – VIRGIN and IMMO OFF version for Peugeot and Citroën (V34.1)

The engine ECU 9666909780 V29006828A is a V34.1 control unit used in selected Peugeot and Citroën models. This is an original module, professionally prepared in VIRGIN mode (clean, reset, cleared of previous vehicle data) or in IMMO OFF version, allowing the car to start without immobilizer adaptation.

The VIRGIN version allows the ECU to be coded to the vehicle using diagnostic tools (Lexia, DiagBox), while the IMMO OFF variant enables quick installation without programming – ideal in emergency situations when time and simplicity matter.

This module was used in popular petrol engines installed in PSA Group cars, including Peugeot 207, 307, 308 and Citroën C3, C4 with engine sizes from 1.4 to 1.6. Produced around 2005–2011, it proved to be a reliable ECU ensuring proper engine and auxiliary system operation.

Each ECU is bench tested, ensuring the buyer receives a fully functional and ready-to-use unit. The VIRGIN version requires adaptation in the vehicle, while the IMMO OFF version offers Plug & Play installation with no coding needed.
