VIRGIN Plug & Play – automatic vehicle pairing
The module has been cleared of data from the previous vehicle and prepared as VIRGIN. After installation and the first ignition cycle, the control unit automatically stores the vehicle’s immobiliser data and pairs itself with the car.
No matching set with a key, ignition switch or body control module is required for installation. However, the vehicle must have a fully functional immobiliser, electrical system, ECU power supply and correctly operating remaining modules.
Possible symptoms of a faulty IAW 5NF.PS control unit
- the engine does not start or starts only occasionally,
- the vehicle stalls while driving or after warming up,
- no diagnostic communication with the engine control unit,
- problems controlling the ignition coils or fuel injectors,
- irregular engine operation and misfires,
- the engine or immobiliser warning light remains illuminated,
- control unit faults return despite a fully functional electrical system and components.
Similar symptoms may also be caused by faulty ignition coils, sensors, wiring, ground connections or power supply. We recommend carrying out a complete vehicle diagnosis before replacing the ECU.
