Blocked Diesel Particulate Filters (DPF's)


Dash Light

A lot of drivers will only know their car's exhaust diesel particulate filter (DPF) is causing a problem when a warning light comes on the dash. Damage caused by a clogged DPF can result in high repair bills, often running into four figures.


Located within the exhaust system, a DPF captures small soot particles, preventing them from being expelled into the atmosphere. As with any filter it needs attention regularly and this is done automatically, by burning off the soot in a process called regeneration. This takes place over a period of steady speed driving for over twenty minutes.  Certain motorists, such as urban commuters, might find that low mileage stop – start motoring may prevent the DPF fitted to their vehicle from re-generating properly.


Legislation

The Government has been keen to ensure that the environment is protected from harmful emissions and it is now an automatic MOT failure to remove a DPF that has been fitted to the vehicle as original equipment from new.

From February 2014 the inspection of the exhaust system carried out during the MoT test will include a check for the presence of a DPF. A missing DPF, where one was fitted when the vehicle was built, will result in an MoT failure.

A vehicle might still pass the MoT visible smoke emissions test, which is primarily intended to identify vehicles that are in a very poor state of repair, whilst emitting illegal and harmful levels of fine exhaust particulate.

 It is an offence under the Road vehicles (Construction and Use) Regulations (Regulation 61a(3))1 to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet. Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use.


Let's Clean Up!

We have invested in a state-of-the-art DPF cleaner that quickly and fully flushes away all of the trapped soot, ash and other debris in an environmentally friendly process.

Eugene Finan, Managing Director of Fastline Group, said: “The new machine is the perfect solution for cleaning DPF’s.  We are seeing more and more vehicles with blocked filters and this machine cleans not only car, but commercial vehicle and bus DPF’s as well. The cost of a new DPF can range from several hundred pounds for a car to several thousand pounds for a truck.  Our facility can provide a clean that is up to 98% effective, environmentally friendly and also cost effective, starting from as little as £195+VAT for a car or taxi.  Umicore, one of the world’s leading producers of catalysts and DPFs used in automotive emission systems, state that analysis confirms there are no remarkable differences between a filter cleaned using the technology we utilise and installing a new one.  More than that, we can professionally clean oil coolers and radiators as well”

We offer a same day by appointment or next day DPF cleaning service, with free collections and deliveries to our local area, or nationwide by carrier.

SCR - Selective Catalytic Reduction

Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NOX with the aid of a catalyst.  This is usually in the form of aqueous ammonia or urea under the trade name of Ad-Blue®, which is injected into the exhaust system by a dosing system from a tank on the vehicle.  This technology enables a lot of vehicles to comply with Euro 6 regulations for exhaust emissions but like all vehicle systems these occasionally need servicing to remove the deposits created by the process.

Our cleaning process can effectively clean SCR’s and save THOUSANDS of pounds!  Below is a video of the cleaning process.
