Symptoms: Indicator stays on after lane change or overtaking manoeuvre; manual cancellation required from 20,000 km | Low | |
| Intermittent injection warning Some vehicles occasionally show an 'Check injection' warning without a permanent fault. Often a software or sensor issue identifiable by diagnostic scan. Symptoms: Engine warning light and 'Check injection' message, often disappears on its own from 25,000 km | Low |
