Truck Aftertreatment Repair in Rock Hill, SC

Your aftertreatment system is critical to emissions compliance and engine efficiency. When it’s not working, you’ll lose fuel economy, power, and possibly the ability to start the engine. At Peters Mobile Services, we offer full truck aftertreatment repair that comes to you.

Remember, if your aftertreatment systems aren't up to scratch, you could quickly breach emissions regulations. This can result in fines of over $45,000 per non-compliant vehicle.

We handle:

• EGR valve replacement for trucks
• Full DPF cleaning for trucks, including forced regeneration
• Active and passive soot removal
• On-site truck DPF filter cleaning
• Diagnosing DEF levels, sensor faults, and regeneration failures
• Aftertreatment resets and verification tests

Warning signs include loss of engine power, increased fuel consumption, black smoke, slow or failed regens, and persistent DPF or check engine lights. The longer you wait, the worse it gets, and the more expensive it becomes. We help you catch and fix it before it costs you a full system replacement.

What is forced regeneration?

Forced regeneration is a manual process that cleans the diesel particulate filter (DPF) in heavy-duty trucks. When automatic regeneration fails, technicians initiate it using diagnostic tools, raising exhaust temperatures to burn off soot. This restores proper exhaust flow, prevents blockages, and maintains engine performance and emissions compliance.

What happens if DEF levels are too low?

If DEF (Diesel Exhaust Fluid) levels are too low, the truck’s system triggers warning lights and may limit engine power or speed to meet emissions rules. Ignoring it can cause the engine to eventually shut down. Regularly refilling DEF ensures compliance and prevents operational downtime.
