Mercedes-Benz Diesel Particular Filter (DPF) may build up excessive soot content, leading to exhaust restriction, and eventually, the check engine light turns on. If you have a diesel Mercedes-Benz and are quoted a new DPF filter, carry out a forced DPF regeneration. In some cases, DPF regeneration may need to be done twice to clean a clogged DPF.

When the DPF becomes blocked, the ECM will modify the parameters of the engine and switch on an extra fuel injector. This extra fuel reacts with the catalyst to burn the soot.
