Removing your DPF may seem like a good idea, because the damage caused by a clogged DPF can result in four-figure repair bill, but recent clamp-downs means removing your DPF is also illegal. As of this year testing stations are now required check for a DPF as part of the MOT test. The vehicle will automatically fail test if the filter had been fitted as standard but is no longer present.
Located within the exhaust system, a DPF captures small soot particles, preventing them from being expelled into the atmosphere. As with any filter it needs emptying periodically and this is done automatically, by burning up the particulates in a process called regeneration.
If you live in London and don't often get to do many Motorway miles your DPF can quickly get clogged up. When a DPF has become too blocked the engine management will not allow any further regenerating and needs to be replaced (this can be very expensive) or professionally cleaned.
