Engine Diagnostics

The check engine light is your car's way of telling you something needs attention. It could be as minor as a loose fuel cap or as serious as a catalytic converter failure. In either case, professional engine diagnostics are essential to correctly identify the issue and avoid unnecessary repairs. At Luxury Auto Care Dubai, our engine diagnostic service goes beyond basic code reading to provide a complete analysis of your engine's electronic and mechanical health.

Our engine diagnostic process begins with reading all stored, pending, and history fault codes from the engine control unit. We then analyse freeze frame data to understand the conditions when each fault was detected. Using live data streams, we monitor critical parameters including fuel trim values, oxygen sensor signals, ignition timing, boost pressure, and intake air temperature to identify any deviations from normal operating ranges. We also perform actuator tests such as fuel injector balance tests, EGR valve operation verification, and variable valve timing system checks.

For performance-related complaints such as power loss, rough running, hesitation, or poor fuel economy, we conduct a more detailed analysis that may include compression testing, ignition system analysis, fuel pressure testing, and exhaust gas analysis. We document all findings in a comprehensive report that explains the fault in plain language, outlines our recommended repairs, and provides a cost estimate. This systematic approach ensures we address the root cause of the problem rather than just replacing parts based on fault codes alone.
