Diagnostics
Dashboard warning light on: what to do
Inspection and diagnostics for dashboard warnings. A photo of the warning helps us arrange the appropriate checks.
Modern cars have dozens of control units, and each can light a symbol on the dashboard. Colour is the first clue: red means stop, amber means check soon.
Lights that need you to stop
- Oil pressure
- Coolant temperature
- Brake system
- Charging system, when combined with other faults
Lights to check soon
- Engine management
- Tyre pressure
- Driver assistance systems
We read the fault memory and explain each message before any repair.
Questions and answers
Which warning lights are the most urgent?
Red oil pressure, coolant temperature and brake lights. Stop as soon as it is safe and call us.
Should the service reminder be reset without a service?
No. Resetting it without the work hides when the car is really due.
