What does the sun symbol on the Audi A6 dashboard mean?
1 Answers
The appearance of a yellow sun warning light on the Audi dashboard indicates that the brake pads have worn to their limit. It is recommended to check the brake pads, and if they are severely worn, they should be replaced immediately. Brake pad replacement timing: According to the maintenance manual, replacement is typically required when the pads wear down to 1.5mm. However, it's best not to wait until this extreme limit; replacement at around 2-3mm is advisable to prevent reduced braking effectiveness or excessive wear on the brake discs. Visual inspection for brake pad replacement: When visually inspecting the brake pads, a general rule is to check their thickness after driving approximately 30,000 kilometers. When the remaining thickness is about 3mm (only 1/3 of the original thickness), you should start considering replacement. Note that some vehicle models don't allow visual inspection of brake pad thickness, in which case you'll need to visit a repair shop for professional assessment. Certain vehicles even provide a self-check function, displaying brake pad wear status on the dashboard.
