1. Describe the action and the result
Instead of “electronics broken”, explain whether the starter is silent, the engine starts and stalls, the battery drains, the locks fail, the dashboard flickers or power steering disappears. State whether it is constant or follows rain, cold weather or storage.
List replaced parts, but do not call the fault resolved until the result is verified. A diagnostic code is useful evidence, yet it does not always prove that the named component must be replaced.
- A full dashboard image rather than one warning lamp
- A short symptom video only when safe
- Diagnostic codes and a garage report
- Battery, starting and key information
2. Know when to stop testing
Repeated starting attempts, random fuse changes or improvised wiring can add damage. Stop if insulation is damaged, modules are wet, there is sparking, melted plastic, smoke or unusual heat.
If the car does not start or its safety systems are unreliable, photographs and its last known condition are enough for an initial assessment. State whether the steering unlocks, neutral can be selected and collection access is available.
3. How an electrical fault affects the offer
Uncertainty often matters more than one error code. The assessment considers model complexity, whether the fault repeats, signs of moisture or previous repairs, the overall condition, documents and transport requirements.
Provide the complete garage estimate if you have one. In the agreement, record the known symptom and diagnostic history rather than an unconfirmed final cause.
