Do you have a DPF

Diesel particulate filter

light on ?

If so we can help

Your options are...

Diagnostics. £66.00

We will carry out a diagnostics test and read fault codes and DPF service data to identify soot content and correct operation of specific sensors. This will eliminate a sensor related fault to correctly determine a DPF is in need of regeneration. £66.00

DPF Regeneration. £100

Includes DPF fault diagnostics service.
We will instruct the engine management system to perform a full static or driven regeneration. The vehicle may be required to be driven under load to generate heat required to complete the regeneration. If DPF additive is also required will advise this.

DPF 3 stage deep clean service £235

Our DPF deep clean service invloves an in depth DPF diagnostics, a deep clean of the DPF which includes a cleaning and flush package which will restore the efficiency of your DPF with a success rate of 98.5%.

DPF treatment - Advised 6 monthly intervals £15.00

This chemical treatment reduces soot emissions, regenerates the particulate filter and gives the engine a good all-round clean.Resulting in lower fuel consumption and the avoidance of regular maintanance costs.Avoids frequent maintenance costs related to the manual regeneration of the blocked soot filter
Especially suited for city driving cycles

The Facts


Diesel particulate filters reduce pollution but you need the full story...here are the pros and cons.
Diesels produce lots of soot (particulate matter) that can cause respiratory problems and contribute to the risk of cardiovascular diseases.

Modern diesel cars (since 2009) have to be fitted with a Diesel Particulate Filter (DPF) in the exhaust to stop this soot passing into the atmosphere.

The aim is an 80% cut in particle emissions but the technology's not without problems.

To maintain performance a DPF has to be emptied regularly. This is usually done passively in a process called 'regeneration': when the exhaust temperature’s high enough, on motorways or fast A-roads.

The collected soot is burnt off, leaving only a tiny ash residue.
A DPF in a car used correctly should be good for well over 100,000 miles.


Active regeneration
Many cars don't get the right sort of use for passive regeneration to work so car manufacturers build in ‘active’ regeneration where the engine control software senses that the filter’s getting blocked and injects extra fuel into the engine to raise the exhaust temperature and trigger regeneration.

Active regeneration will be initiated every 300 miles or so depending on how you use your car and will take 5 to 10 minutes to complete. But it’s a problem if your journey’s too short and the regeneration doesn’t finish.

During active regeneration you may notice:

Cooling fans running
Faster engine idle speed
Automatic Stop/Start doesn’t work
Increased fuel consumption
A hot, acrid smell from the exhaust.
The engine sounds different
Don’t ignore a warning light
If you get a warning light showing that the filter’s blocked, it should be possible to complete an active regeneration cycle and clear the warning light by driving for 10 minutes or so at speeds over 40mph.

If you ignore a DPF warning light and keep driving in a relatively slow, stop/start pattern, soot will build up in the filter until your car goes into ‘restricted performance mode’ to prevent damage.

If you let it get this bad:

Driving at speed alone won’t be enough.
In extreme cases they may have to replace the filter which can cost at least £1000 plus labour.
In most cases there’s only a short time between the DPF being partially blocked and it getting so blocked it needs a manual regeneration.

If you're buying a new car and will use it mainly for town-based, stop/start driving you’d be wise to avoid diesels fitted with a particulate filter

Even if your driving isn't mainly urban/stop-start, you might need to change your driving style to keep the system working properly. Follow any advice in your vehicle handbook.

What prevents normal regeneration?
Frequent short journeys where the engine doesn’t get hot
The wrong type of engine oil – check your handbook
A problem with the fuel system or Exhaust Gas Recirculation (EGR) causing excess soot.
A warning light on the dashboard or a diagnostic trouble code stored in the engine management system.
Going over the recommended service interval
If the vehicle uses Eolys™ additive, a low level in the tank can prevent regeneration.
Low fuel level – generally less than a quarter of a tank – will prevent active regeneration taking place.
DPF additives
Most DPFs are fitted close to the engine where the exhaust is hottest so that passive regeneration is more likely to work.

But some cars use a different type of DPF which needs a fuel additive (Eolys™ fluid) to lower the ignition temperature of the soot particles so that regeneration can occur at a lower temperature.

Additive is stored in a separate tank and automatically mixed with the fuel.
A full tank of additive should last around 70,000 miles.
Don't ignore a warning light showing that the additive tanks need refilling – without additive the DPF will quickly become blocked.


Removal's not a legal option
It’s sometimes suggested that you can get a DPF cut out of the exhaust and the engine management software reprogrammed rather than pay to get it repaired.

DPFs are fitted to meet European emissions regulations and it would be an offence (under theRoad vehicles (Construction and Use) Regulations) to use a vehicle which has been modified in such a way that it no longer complies with the emissions standards it was designed to meet.
Removing a DPF could also invalidate any insurance cover because it makes the vehicle illegal for road use.

Since February 2014 a missing DPF, where one was fitted when the vehicle was built, will result in anMOT failure.
