What is included
A warning light tells you something needs attention, but it does not identify the repair on its own. We combine diagnostic testing with a hands-on inspection to investigate engine, electrical and drivability concerns.
- Discuss when the symptom occurs
- Read codes and test the affected system
- Inspect related components
- Explain the findings before repairs
When to book
- Check engine light
- Rough idle or stalling
- Loss of power
How it works
The same three steps on every job, large or small. You always know what happens next and what it costs.
