Important programming information
The VIRGIN version does not require a diagnostic computer when the vehicle is healthy. After installation, automatic synchronization with the immobilizer takes place. However, if there are wiring problems, body computer errors, issues with the immo ring, the key or CAN communication – adaptation may not be possible. In such cases, the root cause in the vehicle must be repaired first.
Typical symptoms of a faulty ECU
- engine will not start
- no communication via OBD
- cooling fans running at maximum speed

- random sensor faults despite good wiring
