CommercialUltrasonic DPF Cleaning

At The DPF Cleaning Co we understand that a commercial vehicle being off the road for a few days can run into £1000's of lost revenue. Because of the nature of commercial businesses we offer a same day turnaround for commercial vehicle customers meaning you can have your vehicle back on the road as quick as if you replaced the DPF for new. Call us on 01977 600630 today.

If a vehicle fails to regenerate the diesel particulate filter will become blocked and the engine management or DPF warning light will illuminate. The failure to regenerate can be caused by the style of driving or type of journeys covered not allowing the vehicle to reach the parameters required for regeneration or due to the failure of a sensor or component associated with the regeneration process.

It is paramount that the reason the original diesel particulate filter became blocked is correctly diagnosed and rectified prior to installation of a replacement unit. Once this has been done and the new unit fitted the vehicle must be set up correctly with compatible diagnostic equipment. Failure to set up the vehicle correctly after installation will almost certainly lead to the replacement DPF becoming blocked.

What is a DPF?

The Diesel Particulate Filter (DPF) is housed in the exhaust and is designed to capture the soot particles emitted from modern diesel engines.

Sadly, many of the DPF equipped cars are developing problems due to the DPF either failing, clogging up or just failing to carry out a regeneration properly.

This can be down to the age of the vehicle, mileage or could be simply down to the driving style of the owner. Whatever it is, when a DPF warning light illuminates it often means a pretty expensive bill is on its way. 

If this does happen, there are some upsides. A DPF clean can increase your vehicles fuel economy, performance and decrease the likely hood of a breakdown or your car ending up in "limp mode" and save you a pretty large sum of of money if the time has come to replace your Diesel Particulate Filter which can be considered normal for some car manufacturers at 60 to 75 thousand miles and costing upwards of a £1000 and over to replace.

Is my DPF covered under warranty?

The DPF is seen as a consumable by many manufacturers and warranty providers. The cost of replacing or regenerating the filter is normally not covered but we would suggest seeking advice if you are experiencing DPF related issues.

What is Ultrasonic DPF Cleaning?

Ultrasonic cleaners employ oscillating sound pressure waves at frequencies beyond those perceptible by the human ear (Ultrasound). As the soundwaves act on the tank and agitate the contained liquid, cavitation (the implosion of tiny air bubbles within the liquid) is induced.

This acts against contaminants adhered to objects contained in the vessel, separating the two much more gently, efficiently and precisely than would be the case with conventional cleaning methods aided by brushes or solvents.

The ultrasonic cleaning process is used in conjunction with solutions in suitable carrier liquids (often water). As the ultrasonic-induced cavitation occurs, the effectiveness of the aqueous solution is greatly improved to deliver an outstanding clean.

Ultrasonic cleaning is the ideal solution for DPF cleaning, it leaves no contamination or build-up on the DPF filter meaning essentially, the DPF after cleaning is "as new".

What we don't do is "DPF Removal" or what's commonly known as "DPF Delete". To find out why, click on the button below.

Removal is not a legal option

It is suggested from time to time that the answer to failed DPF regeneration is get the DPF removed from the exhaust system rather than pay to get it repaired/renewed.  Indeed there are companies advertising just such a service including reprogramming of the engine management software, but is it legal?

DPFs are fitted to meet European emissions regulations designed to reduce vehicle emissions of particulate matter (soot) associated with respiratory disease and cancer.

According to the Department for Transport, it is an offence under theRoad vehicles (Construction and Use) Regulations (Regulation 61a(3)) 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.

Insurance

You must notify your insurer if the vehicle is modified but such a modification could in turn invalidate any insurance cover because it makes the vehicle illegal for road use.

MOT

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.

With an original equipment DPF removed from the exhaust the car may or may not pass an MOT smoke test - a Euro V (September 2009 diesel) is more likely to fail than one designed to comply with earlier emissions standards.
