How should I get rid of the soot in my DPF?

What's the best way to clean soot from a DPF?

Depends on what the problems are with the DPF. In theory, a 100 mile run on Superdiesel, keeping the revs between 2000 and 2500, but not dropping significantly below 2000 might 'passively' regenerate it and might promote 'active' regeneration. But if something is wrong with the system or if the DPF has become full of ash, it won't. If the DPF is full of ash it might be possible to chemically clean it out by sending it away to Ceramex for about £400. Otherwise it needs replacing at much greater cost.
