Common Warning Lights and Issues We Diagnose

If your dashboard is displaying any of these warning lights, a diagnostic check can identify the cause:

  • Engine Management Light – Can indicate anything from a minor sensor fault to a major engine issue.
  • ABS and Traction Control Light – Possible problems with brakes or stability systems.
  • Airbag Warning Light – Safety system faults that need urgent attention.
  • DPF (Diesel Particulate Filter) Warning – Issues with emissions and exhaust filters.
  • Battery and Charging System Light – Faults with the battery, alternator, or wiring.

Even if there are no warning lights, unusual performance issues—poor fuel economy, loss of power, or strange noises—can also indicate a hidden problem that needs diagnosing.
