Can you force a DPF regeneration?

Forced regeneration: Mechanics can carry out a forced regeneration where they burn the soot off for you. This is expensive, and can only be done 4 times before it damages the filter permanently.

Warm up the engine to operating temperature, then drive it for 15 minutes at constant speed on a motorway. Aim to keep the revs above 2000rpm for this period. The heat generated will help clean the DPF filter and the cars Regeneration cycle will usually kick in under these circumstances.

Can a blocked DPF damage the engine?

Driving the vehicle with a blocked DPF can seriously damage your engine / turbo and it’s not uncommon to have to replace a turbo when the warning light has been ignored for extended periods. The ash residue which remains after successful regeneration cannot be removed and will eventually fill the filter.

Do diesels need to be driven hard?

Driving an old diesel hard may well have shifted any soot build up but to clear any build up in the DPF a regeneration is required, it simply cannot be blown out even though some maintain it can, its an urban myth. Regens take place when required and are controlled by the ECU, you cannot force one yourself.

Can you pressure wash a DPF filter?

Water in a DPF can set the soot/ash into concrete like substance, which will, in turn, ruin the DPF completely. Moreover, high-pressure water damages the cells inside the DPF. Ash removal through compressed air is not enough too. Per say, such a procedure for diesel cleaning service does more harm than good!

Is premium diesel better for DPF?

Use premium (expensive) fuel – This may be a contentious tip but the makers of the expensive versions of diesel claim that their fuels burn cleaner. Presuming that this is true, less unburnt fuel (soot) is likely to be produced, which benefits the DPF, especially in winter.
