2020 Defender


The check engine warning lamp illuminates when the vehicle's ignition is switched on.

The lamp remains illuminated until the engine starts. If the lamp illuminates when the engine is running, an emissions-related fault has been detected. The vehicle remains safe to drive with the lamp illuminated, although qualified assistance should be sought as soon as possible.

With the lamp illuminated, the vehicle may enter limp-home mode. Limp-home mode reduces vehicle performance to safeguard against any further damage to the vehicle. See LIMP-HOME MODE.

If the check engine warning lamp flashes when the engine is running, reduce the vehicle's speed as soon as it is safe to do so. Seek qualified assistance immediately.
