DPF and FAP delete

Most modern Diesel vehicles will come fitted with a Diesel Particulate Filter (DPF). This can also be called an FAP.

If you get a warning message telling you to 'unblock diesel filter' then it is likely you have a problem with your Diesel Particulate Filter. These are designed to 're-generate' using an oil called Eolys Fluid. Alongside a late 'post injection' of fuel this will raise temperatures inside the DPF and burn off any soot.

If you don’t reach the desired conditions for the DPF to ‘regenerate’ or if there is a fault with your vehicle, the DPF will become clogged. If the DPF becomes clogged you will lose a lot of power as the exhaust flow will not be high enough to spool the turbine of the turbo charger. This starts a degenerative cycle of increased smoke/soot which results in the DPF becoming more and more clogged. Eventually you will need to replace the DPF because it is not possible to regenerate to a usable state. When problems occur it’s best to fix them immediately.

In most countries including the UK, removing the DPF will make your vehicle illegal for road use. Always check the laws and regulations where you live before undergoing such a software change. We cannot offer DPF Delete for UK customers if the vehicle will be used on the UK roads.

Keep your DPF fitted and use our DPF friendly tuning software!

We’ve developed a ‘DPF friendly remap’ which is designed to run with similar AFR to the stock mapping to prevent your DPF from clogging. This is a great option if you want to gain a bit of power without removing the DPF system. This does require that there are no problems with the DPF system prior to remapping. Another benefit is that you remain within regulations. These DPF safe settings come as standard in all our Stage 1 remaps which are designed for road use on stock components.

Anti pollution warning

If you have a warning on the center console of ‘anti pollution fault’ this DOES NOT necessarily mean that there is a fault with the DPF or EGR. In-fact, on the Peugeot and Citroen vehicles this is a generic warning for any kind of fault and does not point to any of the anti pollution systems. This fault message can indicate any engine related fault. To find the cause you must go to your nearest garage and have them read for fault codes. This will pinpoint the exact fault. A DPF fault will typically display ‘UNBLOCK Diesel filter’.

Alternatively you can buy ELM327, Peugeot Planet 2000 or LEXIA. This will give the ability to read for fault codes yourself and save a lot of money. This equipment is available from ebay, and is not something we sell..
