Virgin or IMMO OFF?
- Virgin: after fitting it codes itself to the car and immobiliser, no programming – with matching numbers and a working immobiliser.
- IMMO OFF (on request): the engine runs, but a red immobiliser message stays on the dash and an error in diagnostics; it disappears only after the immobiliser is programmed.

Possible symptoms of a faulty ECU
Before you buy, check with diagnostics whether the ECU is to blame. A faulty ECU may be indicated by:
- failure after water ingress or a short circuit in the wiring,
- the engine does not start, no injector control,
- no power supply to the ECU although the fuses are fine,
- no communication with the ECU during diagnostics.
The ECU is not always to blame – wiring, power supply and sensors give similar symptoms, so diagnostics come first.
