Is your Toyota C-HR II diesel struggling under load and puffing black smoke? Chances are it’s a clogged EGR or DPF. Here’s what to check and whether it’s safe to keep driving.
Understanding the Symptoms
If your Toyota C-HR II diesel loses power when accelerating or climbing hills, especially with black smoke pouring from the exhaust, you’re dealing with a common issue in modern diesels. The combination of power loss and dark smoke usually points to incomplete fuel combustion—too much fuel relative to air. That often traces back to problems with the Exhaust Gas Recirculation (EGR) system or the Diesel Particulate Filter (DPF) getting clogged.
