Know the main options before you decide what your vehicle needs.

Normal DPF regeneration burns off trapped soot as part of the vehicle’s emissions management. It is not the same as machine cleaning of a removed filter.
A suitable DPF can be removed and treated using specialist equipment. This may address deposits but does not correct faults elsewhere on the vehicle.
If the filter substrate is cracked, otherwise damaged or beyond suitable recovery, replacement may be needed. Ask your garage to assess the condition and type-approval requirements of any replacement.
There is no single best option for every vehicle. Good diagnosis and a realistic discussion of suitability should come first.
