WHY DIESEL DIAGNOSTICS MATTER

Today’s diesel engines are more powerful and efficient than ever—but they also rely on complex electronic systems to manage everything from fuel injection and turbocharging to exhaust aftertreatment and engine temperature.

If something feels off, we can:

  • SCAN FOR ACTIVE OR STORED FAULT CODES
  • DIAGNOSE CHECK ENGINE LIGHTS AND WARNING INDICATORS
  • ANALYZE SENSOR AND SYSTEM PERFORMANCE
  • TEST ENGINE CONTROL MODULES (ECMS), WIRING, AND COMPONENTS
  • RECOMMEND REPAIRS BASED ON LIVE DATA— NOT GUESSWORK

FAST, ACCURATE, AND DONE RIGHT THE FIRST TIME

Our diagnostic process saves you time and money by avoiding unnecessary repairs. Whether you’re dealing with performance loss, poor fuel economy, hard starts, or emissions issues, we’ll track it down and provide a clear repair plan. At Buffalo City Diesel, we pride ourselves on no-BS service—just real answers, reliable repairs, and a team that knows diesel inside and out.
