Diesel Aftertreatment System Maintenance: Why It’s Essential

Diesel aftertreatment systems play a critical role in reducing emissions and ensuring compliance with modern environmental regulations. However, neglecting diesel aftertreatment system maintenance can lead to increased downtime, higher fuel costs, and even complete vehicle shutdowns.

A recent Transport Topics article by Homer Hogg, "Don’t Let Aftertreatment System Maintenance Be an Afterthought," highlights key best practices to keep your system running efficiently.

Below, we summarize the key takeaways to help you extend the life of your aftertreatment system and avoid unnecessary expenses.

Best Practices for Diesel Aftertreatment System Maintenance

1. Be Proactive

Like any other component of your truck, the diesel aftertreatment system requires regular upkeep. Proactive maintenance ensures vehicle uptime and prevents unexpected failures.

According to industry experts, failure to maintain the system can lead to excessive DPF regenerations, increased fuel consumption, and even a vehicle derate or complete shutdown. Addressing minor issues before they escalate will save you time and money in the long run.

2. Understand Your Warning Lights

Modern diesel vehicles are equipped with warning lights that indicate potential issues with the engine or aftertreatment system. Learning to recognize these signals and responding promptly can prevent costly repairs.

Ignoring these alerts can lead to severe damage, forcing an emergency repair or replacement that could have been avoided with timely maintenance.

3. Recognize the Signs of Clogged Filters

Prematurely clogged diesel particulate filters (DPFs) often signal underlying issues such as:

• Poor air filter maintenance

• Leaks in the intake system

• A filter reaching the end of its serviceable life

Addressing these problems early prevents major breakdowns and extends the lifespan of your aftertreatment system.

4. Save Money by Preventing Costly Replacements

Consistently maintaining your diesel aftertreatment system reduces long-term expenses. Neglecting maintenance could turn a cleanable DPF into one that requires a complete replacement—an unnecessary and costly mistake.

Additionally, a clogged or poorly functioning filter increases fuel consumption, adding to operational costs with every fill-up. Keeping your system in peak condition ensures optimal fuel efficiency and savings.
