DFP

What is a Diesel Particulate Filter?
Diesel Particulate Filters — or ‘DPF’s — are fitted on all modern diesel vehicles. They are filters which remove soot from your vehicle’s exhaust gases before they’re released into the atmosphere. DPFs dramatically reduce the emissions of diesel vehicles, and as such are a requirement to meet modern European emission standards. They are also now an MOT requirement on applicable vehicles.

What is a ‘regeneration’?
DPFs are simply filters which catch soot in your exhaust. Over time, the soot will collect and need to be emptied. The process of cleaning a DPF is called a ‘regeneration’.

Do I need to do my own regeneration?
Nope, thankfully your vehicle should take care of it’s own DFP regeneration. However — if there is an error and the vehicle is unable to complete the DPF regeneration, you’ll be alerted by a warning light/message on your instrument panel. You’ll then need to take action.

How do I know if my DPF is ‘regenerating’?
There are a few key clues..

What can prevent a DPF regeneration?

My warning light is on — what do I do?

Don’t panic. The system is warning you that the vehicle needs your assistance to complete its DPF regeneration.

To do this, you’ll need to increase the exhaust temperature. This can be accomplished by simply taking a 10-15 minute drive whilst maintaining approximately 2500 RPMs.

Should the light not turn off, don’t ignore it! If the vehicle is unable to dispose of its soot it could cause very costly repairs and issues. At this point, you should immediately contact your manufacturer or dealer.

How long does a DPF last?
DPF’s are designed to last 100,000+ miles. They can extend their life with proper care, driving and maintenance.

AdBlue

What is AdBlue?
AdBlue is a mixture of water and urea, which you top up periodically, as you do with fuel. As you drive, AdBlue flows from the tank into the exhaust pipe via a dedicated catalyst. The effect is a chemical reaction that converts most of the NOx molecules into nitrogen and water. This is then released into the atmosphere as steam

As part of the overall drive to reduce emissions, and to comply with the new Euro 6 standards, more and more diesel cars now include SCR (Selective Catalytic Reduction) technology. Used in the right way, SCR can help to reduce Nitrogen Oxide (NOx) emissions by as much as 90%, with fuel efficiency also increasing by between 3% and 5%.

How do I use it?
For the technology to work, vehicles need to be fitted with a special tank for storing a liquid-reductant agent known as AdBlue®. So if your vehicle is fitted with AdBlue® there are a few things you’ll need to know.

How do I fill up the AdBlue tank?
AdBlue® is available from an increasing number of fuel stations and motorway services, but your dealer will also be able to supply AdBlue®. New vehicles tend to have a filling point next to the fuel cap, however it does vary depending on the manufacturer and model. So, it’s best to refer to the owner’s manual before you start.

How will I know when it’s needed?
It’s important to take action as soon as you see any relevant warning lights on your dashboard. There are three possible warnings:

Who pays for the AdBlue®?
Because it’s a solution you top up periodically, as you do with fuel, the costs are not covered by the maintenance contract and are therefore payable by the driver of the vehicle. The only exception to this is if the service schedule states that the fluid needs to be changed (rather than topped up).

Smoking Sign

Smoking isn’t allowed in any work vehicle that more than one person uses.

As an employer, you are responsible for ensuring that the correct signage is used within your workplace. Failure to clearly display no-smoking signs may result in a fixed penalty notice of £200 or a maximum fine of £1,000 if convicted by a court

Anyone caught smoking in a company car or van faces a £50 fixed penalty fine or being taken to court and issued with a £200 fine and a conviction.
