No, it’s illegal to remove or delete your DPF. Your vehicle has been designed by the manufacturer to operate with a DPF system. It is illegal and will also void the manufacturer’s warranty on your vehicle and Australian consumer law protections. Removal or deletion of your DPF will also impact your vehicle�’s insurance policy due to fire risk.  DPFs are fitted to enable the vehicle to comply with the Australian Design Rules (ADR) emission requirement levels.

DPF systems are very technical and some mechanics may not fully understand their complex operation, and in our experience that also includes some dealerships. Some workshops may use the “keep replacing parts” method hoping it’ll solve the fault, but inevitably your bank balance will cop a hiding! Try to find a diesel specialist workshop that frequently deal with DPF systems and understand how they work.

To help prevent your DPF from blocking up again try to drive the vehicle at least once a week on the highway for 30 minutes or more. This will ensure that the DPF will perform a passive regeneration (self-activated) and the soot gets cleaned from your DPF. Ensure that the vehicle’s service schedule is adhered to and correct engine oil is used. Find an independent mechanic that is familiar with your make and model of vehicle and is experienced in servicing modern diesels.

There are some chemical fuel additives on the market that claim to be able to clean blocked DPF’s but do not remove ash build up. They are extremely ineffective and a waste of your hard-earned money. Some additives may remove some soot from the filter walls but there is a large amount of chemical residue retained in the DPF itself which is absorbed by the remaining ash content. This residue contributes to future blockages occurring in a much shorter time frame.

As an owner/driver of a Diesel powered vehicle you need to clean the DPF regularly as this will save you money in operating costs and prevent costly downtime in the long run.  Maintenance schedules or cleaning cycles vary according to the type of vehicle and how your vehicle is being used.  To keep your DPF’s optimal operating performance we suggest a clean at least every 12 months. Shorter timeframes may be needed if your vehicle is exposed to:

Pressure drop evolution with soot accumulation in the DPF showing rapid initial rise in pressure drop due to soot accumulation in the filter pores (1) followed by a gradual increase as soot builds a layer along the walls (2).  If the DPF develops too much pressure then the last type of regeneration must be used - a forced regeneration. This can be accomplished in two ways.

Diesel particulate filter for heavy-duty vehicle (a), cross-section viewing showing filtration processes within several DPF channels (b), and close-up view of particle capture and build-up on the channel walls (c).  Passive regeneration occurs during the vehicle’s normal operating temperatures when engine load and vehicle drive-cycle create temperatures that are high enough to regenerate the soot build up on the DPF walls. The DPF will oxidise the particulates anywhere between 275-360⁰ Celsius. Fuel Injection

Diesel Particulate Filter  Unlike the DOC, the diesel particulate filter (DPF) is a wall-flow filter consisting of a matrix of materials (a composite of cordierite, silicon carbide, or metal fibres) that traps any remaining soot that the DOC couldn’t oxidize. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can achieve soot removal efficiencies approaching 100%.
