What are strong bullet points for an automotive technician?

Strong bullets name the system, the diagnosis or repair, and a result such as time saved or a vehicle returned right first time. These fictional examples show the style:

• Example: "Diagnosed intermittent misfires using scan tools and oscilloscope readings, tracing faults to wiring and ignition coils."
• Example: "Completed scheduled services, brake jobs and suspension repairs on 6–8 vehicles per day."
• Example: "Carried out automatic transmission removal and refit, including fluid service and adaptation resets."
• Example: "Performed warranty repairs to manufacturer procedures and documented them for claims."
• Example: "Kept comeback rates low by road-testing every vehicle before release."
• Example: "Trained two apprentices on service procedures and workshop safety."

Avoid lines like "fixed cars". The system and outcome show your skill.
