Exhaust Aftertreatment System Issues (DPF/SCR)

Diesel Particulate Filters (DPF) and Selective Catalytic Reduction (SCR) systems can become clogged or malfunction, leading to reduced performance and emissions-related fault codes. This is common in heavy-duty diesel trucks. Estimated repair cost: $500 - $2,500+.

The turbocharger can experience wear over time, leading to reduced boost pressure and potential failure. Proper lubrication and avoiding excessive heat are key to its longevity. Estimated repair cost: $1,000 - $2,500.

Diesel fuel injectors can become clogged or fail, impacting fuel atomization and engine performance. Regular use of quality fuel and occasional fuel system cleaners can help. Estimated repair cost: $600 - $1,500.
