What is it?

A warning light that stays on (for example ABS, airbag or engine fault) points to a fault that has to be read out first.

Repair indication: mediuma targeted repair at the garage.

How to check it at the viewing

Switch on the ignition: all lights come on briefly and go out after starting. If one stays on, ask about the cause.

Ask the seller: Does a warning light ever come on, and has the fault been read out?
