10. What does a green-tagged tool in a properly maintained Audi workshop inspection program typically indicate? → The tool has passed its most recent safety inspection and is approved for use
11. When replacing brake fluid on an Audi with an electronic parking brake (EPB), what must be done before compressing the rear caliper pistons? → Use an EPB service mode via scan tool to retract the caliper
12. What is the required action if an Audi technician sustains a cut from a sharp sheet metal edge and the bleeding does not stop within a few minutes? → Seek immediate first aid or medical attention and report the injury per shop protocol
