What to watch out for during assembly
– Immobilizer/BSI: The ECU is paired with the vehicle. After assembly, it is necessary:
– either clone the contents of the original drive to this one (transfer data/EEPROM),
– or put the unit in “virgin” state and pair with diagnostics (e.g. DiagBox/PP2000) according to the vehicle’s PIN.
– Compare before ordering:
– marking IAW (48P2.72),
– PSA numbers (9648568480 / 9645989480),
– design of the connector.
– Recommendation: Check compatibility by VIN and part numbers or consult diagnostics/service.
