Check Engine Light & Powertrain Diagnostics

An illuminated check engine light can signal anything from a minor loose gas cap to a critical internal engine fault. At Alfa Garage Miami, we don't just clear the code and send you on your way; we pinpoint the exact root cause to protect your vehicle's performance and longevity.

Electrical System & Module Diagnostics

From power windows to the central Body Control Module (BCM), modern vehicle electronics are deeply interconnected. When a glitch happens, we don't guess—we measure. Using precision digital multimeters and oscilloscopes, our specialists accurately map wiring shorts, track down parasitic battery drains, and isolate faulty modules with factory-level precision.

Transmission & Drivability Troubleshooting

If your vehicle is slipping between gears, hesitating under acceleration, shifting harshly, or idling roughly, your powertrain control system is struggling. To diagnose the issue accurately, our team utilizes advanced live-data scanners to monitor solenoid performance, clutch pressures, and engine misfire counters in real-time during a targeted test drive.

Evaporative Emissions (EVAP) Leak Testing

Your vehicle’s EVAP system is a sophisticated, closed network engineered to capture raw fuel vapors and prevent them from escaping into the atmosphere. Because even a minor leak triggers an immediate dashboard warning, pinpointing the issue requires specialized gear. We utilize high-density smoke machines to safely pressurize the network, allowing us to visually locate microscopic pinholes in fuel lines, charcoal canisters, or faulty purge valves with absolute precision.

Check Engine Light & Electrical Diagnostics — $195

Professional diagnosis, not guesswork. Our ASE-certified technicians use factory-level scanners, oscilloscopes, and smoke machines to pinpoint the real cause — we don't guess. What's included:

  • Full interview about your symptoms
  • Complete scan of all vehicle modules (engine, transmission, ABS, airbag, body)
  • Live-data analysis and pinpoint testing as needed
  • Visual inspection related to the complaint
  • Written findings and an honest, itemized estimate before any work begins How long it takes: most diagnostics take 1–2 hours. Complex or intermittent issues can take longer — we'll tell you upfront. Our promise: when you approve the recommended repairs with us, $100 of the $195 diagnostic fee is credited toward your final invoice. Appointment only.
