Land Rover Discovery 3 - All fault lights on in diagnostic check - azzman
Recently my car broke down with all faults showing on the dashboard.
I've had all filters replaced as red diesel has been used in it before. But the problem still persists, does anyone know what this could be as the garage aren't too sure? Many thanks

In all honesty I would look for a garage that knows what they are doing !

All the dash lights will be on with the ignition until lit starts. Low battery voltage or charge rate will cause all the warning lights too be on, but on a disco it needs proper diagnostics with a proper check and no more than 2-3 hrs the cause should be found

All it needs is experience, proper diagnostic equipment and a clued up tech
