Frequently Asked Questions
Is a check engine light urgent?
A steady check engine light means there's an issue that needs attention but isn't immediately dangerous. A flashing check engine light indicates a serious problem (usually engine misfire) — reduce speed and get it diagnosed immediately to prevent catalytic converter damage.
What's the difference between a code read and a diagnostic?
A code read ($0-$50) tells you WHAT code is stored (e.g., P0420). A proper diagnostic ($50-$200) tells you WHY — the technician tests specific components to identify the root cause. A code is a starting point, not a diagnosis.
Why does car diagnostic test cost different in San Antonio than other cities?
San Antonio's costs reflect local labor rates driven by the military-tourism-healthcare economy, humid-subtropical climate conditions that affect materials and scheduling, and relaxed permitting requirements. The competitive labor market also influences competitive pricing.
