Maruti Suzuki EGR Valve Fault — Top Causes

While egr valve fault affects multiple brands, Maruti Suzuki has specific factors that make it worth a specialist diagnosis.

• Heavy carbon soot deposit clogging EGR valve — most common on diesel cars in city use
• EGR valve solenoid electrical fault or wiring harness break
• EGR cooler blockage from coolant or soot — causes EGR system failure
• Faulty EGR position sensor giving incorrect feedback to ECU
• EGR valve stuck open causing rough idle from over-recirculation
