Case files / evidence over theatre
Show the thinking, not just the finished part.
A case file can make workshop quality visible: the reported symptom, the checks performed, the decision made, and the way the outcome was verified.
Three diagnostic scenarios
Open the evidence trail.
Each file moves through the reported symptom, the evidence path, the decision point, and the final verification check.
CF / 001Starting / electricalIntermittent no-start after short journeys
The starter response changes when the vehicle is warm, but the battery has already been replaced.
- Concern reproduced warm
- Supply voltage held under test
- Control-side voltage drop changed with temperature
Trace the control circuit before recommending another battery or starter assembly.
Repeat hot-start cycles and compare the control-side reading after the approved repair.
CF / 002Braking / wheel endSteering vibration under braking
Vibration is reported at road speed and becomes stronger with light braking.
- Road-speed context recorded
- Wheel-end play checked
- Disc and hub condition measured rather than judged visually
Base the recommendation on the measured source of runout or wear, not on vibration alone.
Repeat the same road-test condition and record the post-work result.
CF / 003Cooling systemSlow coolant loss with no obvious puddle
The level drops over several days without a clear leak on the floor.
- Cold level and cap condition recorded
- System pressure behaviour observed
- Temperature-dependent leak points inspected
Identify the leak path and system condition before replacing visible nearby parts.
Recheck pressure stability and coolant level after the approved repair and heat cycle.
Publishing case evidence responsibly
Permission, context, and a repeatable check.
A useful published case protects customer privacy while still showing the reasoning behind the work.
Written permission for imagery and story use
No names, plates, VINs, addresses, or private paperwork
A precise symptom and relevant vehicle system
Photos or readings that support the decision
The work the customer actually authorized
A repeated test tied to the original concern
Your vehicle concern deserves the same clarity.
Prepare what you have noticed and let the workshop decide which evidence is needed next.
