Dashboard Warning Lights Explained

Red, amber or green? A quick guide to what your dashboard is trying to tell you, and when to act.

Colour is your first clue

As a rough guide, red usually means stop and act now, amber means something needs checking soon, and green or blue is simply telling you a system is on. When in doubt, do not ignore it.

Lights worth acting on quickly

Some of the most common warning lights include:

  • Engine management light: have it diagnosed before it affects running or the catalytic converter.
  • Oil pressure (red): stop safely as soon as you can, low oil pressure can wreck an engine.
  • Battery/charging: the charging system needs checking.
  • Brake warning: could be the handbrake, low fluid or a fault, get it looked at.
  • ABS: the car still brakes, but the anti-lock system needs attention.

Let us read the real cause

A warning light is only the start of the story. Our diagnostic equipment reads the stored fault codes and, just as importantly, our technicians interpret them properly so you fix the genuine cause, not a symptom.
