You should drive your vehicle for approximately 15 minutes keeping the engine revs between 2000 - 2500 rpm. This is probably best done on an A road.
Anyway, does DPF Cleaner Really Work?
Yes, you can use Redex DPF Cleaner to prevent problems as well as cure them. ... However, it's not a very reliable way to keep the DPF working. Redex DPF Cleaner is much easier as it lowers the temperature that the soot burns at, so it will burn off during normal driving.
Furthermore there, what can I use to clean my DPF filter?
Beside, can you clean a DPF yourself?
Don't DPFs clean themselves? In theory, yes. “Passive Regeneration” or if appropriate Active DPF regeneration will take place as part of a healthy diesel engine running cycle, but active regeneration can fail once a blockage reaches a certain level. Sometimes a “forced” regeneration may be carried out by a mechanic.
How many times can you regen a DPF?
Active regeneration will be initiated every 300 miles or so depending on how you use your car and will take 5 to 10 minutes to complete. But it's a problem if your journey's too short and the regeneration doesn't finish.

Jet washing may remove surface carbon, but DPF Clean Team states that it will not remove any internal carbon or oil contaminants. ... Cameron concludes: “Professional DPF cleaning is a quicker, more accurate, and cost-effective solution to unblocking a DPF, catalytic converter or silencer than investing in a new unit.
If there is black smoke leaving your exhaust pipe, this is an obvious indicator that your DPF filter is not working properly. Like any filter, your DPF will, over time, start to form a blockage from the waste that it holds and will need to be cleaned.
➢ Prices charged for DPF Cleaning range between $350 and $500, depending on location and cleaning method used. ➢ Some manufacturers offer exchange programs in lieu of cleaning, which usually run between $600 and $800.
Many people are taking out the DPFs from their vehicles and bringing them to a car service centre in order to blow them out with the air compressor or clean them out with water. ... Water in a DPF can set the soot/ash into concrete like substance, which will, in turn, ruin the DPF completely.
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.
Dokter says a DPF filter, itself, can cost anywhere from $5,000 to $10,000 to replace so it doesn't take long to justify the cost. He says the DPFs found on most Tier 4 engines build up soot and ash during use and lose their effectiveness.
It is much more normal for DPFs take 10k miles to become blocked. However, this only happens if the owner NEVER takes their car for a run. Once a week, once a fortnight, or even once a month, a 30–60 minute run at a constant 3–4k RPM will ensure it doesn't get blocked.
To make sure that the regeneration takes place, most manufacturers suggest that every few hundred miles, the car is driven for a period of more than 15 minutes at a consistent speed in excess of 40mph. Doing this should clear the filter.
The DPF will not regenerate if: Theengine management light is on for any fault; There is a faulty EGR valve; There is less than 20 litres of fuel in the fuel tank, if the fuel light is on or the engine management light is illuminated.
