A DPF (Diesel Particulate Filter) is a device fitted to the exhaust system of many new diesel cars. It's there to reduce the amount of harmful particulate that's emitted from the tailpipe. They perform this function well, but if the vehicle is used predominately at low speeds, for example city driving- they can pose problems and become blocked.
