Diesel Particulate Filter Cleaning & Solutions

Solve complicated issues with your vehicle’s diesel particulate filter by booking in for a DPF filter clean and full diagnostic check today. Infinitech also offers a mobile service*.

Solve your diesel particulate filter problems with a DPF solution service from Infinitech Tuning. The diesel particle filter is a device in the exhaust system that was designed to reduce or remove soot from the exhaust gas of a diesel engine. As with any filter, they eventually fill and block up.

The filter must be efficient to allow exhaust gases to flow freely and not impact your engine’s performance. The cure is your car’s regeneration program, and DPF cleaning is an essential part of it.

The DPF Regeneration Process

The diesel particulate filter regeneration process can be active or passive.

Active: The filter is monitored by the engine ECU and when it is 45-50 percent full, small changes to the injection duration and timing are made. This raises the exhaust temperature which, in turn, burns off the soot particles.

Passive: When the vehicle is used on the freeway or is driven at high revs, the exhaust reaches high temperatures and soot particles are burnt off. This provides DPF filter cleaning as a side-effect of driving.

What to Do When DPF Regeneration Problems Arise

If, by no fault of your own, the filter does not regenerate efficiently, then the soot is free to build up more and more. This could be caused by stop-start driving or short journeys. When the filter becomes 75 percent blocked and your engine management warning light or DTC light comes on and no amount of driving at speed will clear the filter out, you will need to see Infinitech.

This technology seems to be problematic as many drivers are experiencing DPF faults even though they mostly use their vehicles for freeway driving. This can be due to a very high 5th or 6th gear which doesn’t lift the revs hard enough.

Fixing Diesel Particulate Problems

Infinitech can reprogram your ECU to safely disable your DPF system (for off road vehicles or vehicles with exemptions only). All DPF fault code data will be erased and you can remove the filter from the exhaust system with a straight through pipe.

The DPF system is turned off using the latest tuning software and can easily be re enabled if necessary in the future.

*We also offer a mobile DPF cleaning service with no need to remove the filter from the vehicle using proven JLM  Diesel DPF Cleaning products.

Combined with our state-of-the-art diagnostic system, covering 99 percent of all diesel vehicles fitted with diesel particulate filters, we can quickly diagnose and fix any related problems getting you back on the road sooner without your vehicle getting stuck at a garage for days.

Thank you Google for putting me onto Infinitech – fantastic customer service, prompt, informative and welcoming. It was great to have access to a loan car, made the whole exercise really simple. My Peugeot 308 now has it’s DPF fluid full and is running beautifully (and cleanly) thanks to a ‘triple treat’


My Holden Captiva had a severely blocked DPF. After taking it to numerous mechanics and also the Holden dealership, all gave me no confidence that they would be able to fix the problem.

After doing a google search I found Infinitech Tuning. I called and spoke to Roger who was clear and precise in his communication. Just through talking to Roger I sensed that I had finally found a trustworthy mechanic who could get my car back up and running all at a reasonable price.

I took it in and they had the blocked DPF and cracked hose fixed the next day. Its now been over a month since they serviced my car and its running just like new. Brilliant service and highly recommend the guys at Infinitech Tuning.


It’s great to see a garage looking into other methods of repair and rejuvenation of DPF other than just remove and replace used by so many. It reduces the wastage of high grade materials, saves time and effort and most importantly to me it saves a considerable amount of money! Good effort into bringing the European future into the Perth now!! Good and knowledgeable guys to top it off!
