What Are the Signs of a Bad DPF?

Common signs include frequent regenerations, reduced engine power, excessive fuel consumption, warning lights, and engine derate conditions. A clogged DPF restricts exhaust flow, increasing backpressure and affecting overall engine performance.

What Happens When an EGR Goes Bad?

When an EGR valve fails, it can cause rough idle, loss of power, increased emissions, overheating, and poor fuel efficiency. In severe cases, it may trigger limp mode or engine derate to protect internal components.
