Green / Blue Lights – Informational Indicators

These lights confirm that a system is active and working as designed.

Engine Management Warning Light (Check Engine)

What It Indicates

A fault within the engine management or emissions control system.

Common Causes

• Faulty oxygen (lambda) sensor
• Loose or damaged fuel cap
• Misfiring spark plugs or coils
• EGR valve malfunction
• Turbo boost irregularities

What To Do

• If the light is steady, drive cautiously and book diagnostics
• If flashing, stop driving immediately to prevent catalytic converter damage

Oil Pressure Warning Light

What It Indicates

Critically low engine oil pressure.

Likely Triggers

• Insufficient oil level
• Oil pump failure
• Blocked oil pickup or filter

• Electrical load too high

Impact

No safety concern; fuel-saving feature temporarily disabled.

Preventing Dashboard Warning Lights in the Vauxhall Mokka

Routine Maintenance Best Practices

• Regular oil and filter changes
• Battery health checks
• Correct tyre pressures
• Periodic diagnostic scans

Driving Habits That Reduce Warnings
