Ignoring a DPF light can cause numerous issues for a truck and even cause the truck to go into limp mode and/or stop. Diesel particulate filters (DPFs) are important to a diesel trucks exhaust system and vital to its emission control. DPFs remove soot in the exhaust. Over time soot builds up in the filters causing the filters to fail and the truck goes into limp mode. DPF repair and DPF cleaning can recover a truck from limp mode and are required to keep newer trucks running along with regular regens. Our skilled technicians are well trained in DPF repair and DPF cleaning guaranteeing you minimal down time.
