The Ultimate Peugeot 108 Dashboard Warning Lights Guide: Symbols, Meanings, Safety & Fixes
Everything you need to know about every Peugeot 108 dashboard warning light – from common red alerts to obscure advisories. Definition, types, colours, how to react, safety, advantages, disadvantages, troubleshooting and expert FAQs.
Definition: What Are Peugeot 108 Dashboard Warning Lights?
DEFINITION Dashboard warning lights are part of the Peugeot 108 onboard diagnostic system. They illuminate to indicate system status, failures, or required maintenance. The colour determines urgency: red (stop immediately), amber (check soon), green/blue (information/active). Understanding these symbols helps prevent breakdowns and expensive repairs.
Why Do Warning Lights Illuminate?
They activate when an electronic control unit (ECU) detects a value outside normal range. Examples: low oil pressure switch triggers red oil light; oxygen sensor reports mixture error → amber engine light; lost communication with ABS module → amber ABS light. Modern Peugeot 108 has over 50 sensors that can trigger warnings.

How to React to Peugeot 108 Warning Lights (Step by Step)
SAFETY Red light: Pull over when safe, turn off engine. Check fluids, but do not restart if oil or temperature light stays on. Call breakdown service.
Amber light: Reduce speed, avoid hard acceleration. If the light is steady, you can drive to a garage. If flashing (engine light), stop immediately to avoid catalytic converter damage.
Green/blue: No action, they show systems in use (fog lights, high beam).
Is It Safe to Drive with Warning Lights On?
Red lights: NEVER safe. Stop the car. Amber lights: Generally safe for short trips if no performance loss, but have it checked. Flashing amber = high urgency (misfire). Green/blue – safe.
Driving with an ignored amber engine light can lead to failed emissions, damaged spark plugs, or clogged catalytic converter.
Advantages of Understanding Dashboard Lights
- Prevent breakdowns – early detection saves money.
- Safety – react correctly to brake/airbag warnings.
- Better communication with mechanics – describe exact light.
- Avoid MOT/test failure – warning lights cause instant fail.
- Reduce repair bills by fixing small issues early.
Disadvantages of Ignoring or Misunderstanding Lights
- Engine seizure due to low oil (ignoring red oil light).
- Brake failure from worn pads or low fluid.
- Costly catalyst replacement from misfire.
- Breakdown in unsafe location.
- Void warranty if neglect proven.
Use of OBD2 Scanners & Professional Diagnosis
To read Peugeot 108 fault codes, a mechanic connects an OBD2 scanner to the port under the dashboard. The code (e.g., P0171) pinpoints the problem. Some owners use Bluetooth adapters with apps. However, codes need correct interpretation – a sensor fault might be caused by a wiring issue.
Advanced tip: The Peugeot 108 has a built-in diagnostic mode: press and hold the trip reset while turning ignition on – some versions show segment check and stored warnings. But for exact codes, use a scanner.
Common Peugeot 108 Warning Light Issues by Year
| Model year | Common light | Typical cause |
|---|---|---|
| 2014-2018 | Amber engine light | Oxygen sensor (lambda) or ignition coil failure |
| 2018-2022 | Amber tire pressure | Sensor battery low or after tyre change not reset |
| All | Red oil light flicker | Oil level low or pressure switch faulty |
| Diesel versions | Amber glow plug light | One or more glow plugs failed – harder cold starts |
