Since 2009 exhaust emissions standards for new vehicles have required fitment of a DPF (Diesel Particulate Filter) to reduce carbon footprint.
DPF reduces diesel particles soot into the atmosphere. However, lack of motorway or long distance driving can cause this part to block.
The process of DPF Regeneration
To maintain your vehicle's performance, Eurofit Autocentres can perform an active DPF regeneration. This process involves burning the blocked soot at a high temperature to leave only a tiny ash residue.
When the soot loading in the filter reaches a set limit (about 46%) the vehicle's ECU will initiate post combustion fuel injection to increase the exhaust temperature & trigger regeneration. If you undertake a lot of short journeys or stop & start trips, the process will not complete & trigger the engine management light.
It should be possible to complete a regeneration cycle & clear the warning light by driving for about 10 minutes, at speeds greater than 40mph.
DPF removal is illegal
DPFs are factory fitted to meet European standards to reduce carbon footprint.
According to the Department for Transport, it is an offence to use a vehicle which has been modified or had its DPF removed. This makes the vehicle illegal to drive on public roads, invalidating your insurance and MOT.
How can Eurofit Autocentres help?
At Eurofit Autocentres we are able to diagnose & regenerate Diesel Particulate Filters (DPFs).
The DPF helps to reduce the amount of soot that is released into the atmosphere by diesel vehicles. A manual regeneration may be required if your vehicle has suffered from a DPF blockage or the DPF warning light is active.
Common exhaust faults include: blowing, hole in exhausts, catalytic converter faults, DPF light on dashboard, corrosion, internal breaking of exhaust fibres & limp mode.
Eurofit Autocentres advise booking a diagnostic first if you suffer from any of the common faults, as on occasions mechanical or electrical components can cause similar symptoms.
