What is a DPF
A Diesel Particulate Filter, also known as a DPF is a filter designed and integrated into the exhaust system of diesel vehicles to trap and safely remove Diesel Particulate Matter or Soot from the exhaust gasses. The aim of the DPF is to remove on average 80% of harmful toxins and lower the emissions of the diesel engine to meet with Euro standards. Regeneration is the process required to clean the DPF and is automatically carried out via the vehicle’s ECU when the soot level inside the DPF filter reaches up to 45% (some vehicles will regenerate much sooner).
The DPF filter has a lifespan of around 70,000 miles (varying dependant on the vehicle) and once the filter can no longer be regenerated or is damaged, then a replacement filter is required. There is a DPF Removal service available, however due to the recent change in legislation it will now be an MOT failure if you have the DPF removed – so we are offering the DPF Removal as an “Off-Road” service only.
Replacement DPF Filters
The Diesel Particulate Filter (DPF) is a very expensive part to replace when it blocks up. You can in most cases regenerate the filter to get more life out of it but eventually it will need replacing. There are many copy filters available on the market for most makes & models of vehicle but are of poor quality and 9/10 times will only be applicable to vehicles that are over 4 years old. So if you have a new Mazda 6 2.2D for example, then you won’t be able to find a copy filter anywhere on the market – and a new filter direct from Mazda will cost you around £1600 +Vat.

dpf light stay on
Hi I have just purchased a 2013 Vauxhall Astra CDTI SRI S/S 2ltr Estate Manual with 20k miles on the clock & the DPF warning light is on. Can you advise on my best course of action please? Also with an expected life of 70k miles why should it go so soon? My Mercededes E320cdi was still going strong on the original DPF at 120K miles?
Thanking you in anticipation. Jon Spencer…
Sorry a bit more information for you. The Astra 2CDTi has 20K miles on the clock & has full Vauxhall service history. Should I cut my losses and have your modification(Quote please) or should it be down to Vauxhall? Im sorry to burden you with these questions but you are the only ones who seem to know what your talking about! My journeys are generally over 20 miles and I do like to drive with a bit of “gusto” meaning Im no slouch when driving! my average miles will be around 10k a year but I do want to enjoy the benefit of having a diesel & its economy & performance.
Regards, Jon…
I have a mazda 3 1.6 diesel REG. SL57HKX. It has 120000 miles on the clock and a problem regenerating. Decided it may be a good idea to replace the dpf. Please advise a price for a suit a blue replacement along with the fixing kit and any helpful tips.
Many thanks.
I have a mazda 6 2.0 TDI 2006 GK56*** And my dpf is beginning to cause problems, would you be able to provide me with a quote to my email for one of your custom build replacement DPF’s.
Also I have been told they can be tricky to replace due to the sensor bolts fusing into the current dpf due to the heat, if true is there a good way around this?
The sensors appear to be £400+ each. Or would you recommend a complete DPF removal in this case?
Kind Regards
Ian
Hi There.
I Recently had a dpf Clean from a mobile dpf mechanic on my fiat fiorino diesel van which immediately after i had the work done it seemed running perfect again for a while,no light coming on no smoke etc.But 1 month later the problem has returned with lots of smoke from the exhaust whilst driving and loss of power also when on the road driving.Tried smoothing it out along motorway which helped temporary but even doing this the problem seems to return with the dpf light coming back on when driving so i would like some advice for the best thing to do please …Thanks..Paul
