TerraClean also targets your car’s DPF (Diesel Particulate Filter), which works to reduce emissions by capturing particles of soot and diesel in your car’s exhaust pipe. Though usually self-cleaning, your DPF can easily become blocked and cease to work correctly. In the worst cases, a blocked DPF can prevent a vehicle from functioning at all. The standard TerraClean process improves the function of the DPF, but if the problem isn’t easily resolved, specialised technology can regenerate the DPF and clear out any accumulation of particles. Buying a replacement DPF can be a significant cost. A TerraClean service prevents this unnecessary expense, restoring your existing DPF back to high-performance functionality and lowering your engine’s emissions.
