One of the most common mistakes fleets make is failing to service the aftertreatment systems often enough. DPFs require regular cleaning, and the rest of the system requires regular inspections. Upstream leaks in the system are often the cause of downstream failures. The most common mistake diesel technicians make when diagnosing problems and performing repairs is to look at one part of the system instead of the four parts that make up the complete system. For example, the DPF is often blamed as the source of the problem when it is the symptom of a problem elsewhere in the system.
