Do not just clear it and hope

The MIL or check engine light can cover anything from a minor emissions warning to a fault that risks damage. The first job is to understand what the car has recorded and whether it is safe to keep driving.

We start with the warning message, scan data and symptoms, then explain whether the vehicle needs servicing, a specific repair or deeper fault-finding.

What happens next

You do not need to know the workshop term. Tell us the symptoms and we will explain whether the car needs servicing, fault-finding or repair work.

What we look at

  • Engine management light, check engine light, MIL, EPC or emissions warning.
  • Code scan and basic assessment with printout where applicable.
  • Advice on whether the car should keep being driven or needs booking quickly.
  • Clear route into DPF, EGR, AdBlue, misfire or engine fault checks if needed.
