EGR Systems

Signs of EGR Failure

Decreased Engine Performance: A malfunctioning EGR system can reduce engine power and fuel efficiency. This is caused when the EGR valve gets stuck, either in the open or closed position, affecting the air-fuel mixture.

Increased Emissions: A failed EGR system allows higher levels of nitrogen oxides to escape into the atmosphere, increasing the vehicle's emissions.

EGR System Repairs

EGR system issues require prompt and skilled attention. Our repair services include:

Valve Cleaning or Replacement: EGR valves can become clogged with soot and carbon deposits over time. We offer thorough cleaning services or valve replacement if necessary.

EGR Cooler Repair: EGR coolers can crack or clog, necessitating repair or replacement. We ensure that the cooler effectively reduces exhaust gas temperatures.

DPF Systems

Signs of DPF Failure

Increased Regeneration Frequency: If the DPF system is not functioning correctly, it may need to regenerate more often, indicating a damaged filter.

Reduced Engine Performance: Similar to EGR issues, a failing DPF can decrease engine efficiency and power.

Warning Lights: Dashboard indicators may light up to signal DPF issues requiring immediate attention.

Engine D-Rate: When a D-rate Indication occurs a common cause would be failed exhaust sensors or clogged exhaust filters.

DPF System Repairs

DPF issues demand expert care, and our services include:

Deep Cleans: We offer deep cleaning services to remove ash and soot buildup, extending the life of your DPF.

Forced Regeneration: When normal operation doesn't clear the DPF, we perform forced regeneration to burn off excess particulate matter.
