The Problem: DPF Failure

Under the new changes to the law, diesel cars fitted with a DPF will now be given a ‘Major’ defect and automatically fail the MOT test if they emit ‘visible smoke of any colour’ during metered checks the MOT inspector will then class this as a ‘Major’ defect and result in failing the car. Our DPF Assist team has treated many vehicles successfully which has saved our customers hundreds of pounds by using a professional-grade DPF Cleaning method.

Our DPF Solution

We find that most of our customers are surprised by the cost they incur due to a DPF fault. In many cases, our customers report that the same problem re-emerges. We have therefore put together a service plan to help save costs. The service plan cost varies by vehicle.

Once a Diesel Particulate Filter (DPF) becomes blocked, replacing the DPF or cleaning the DPF will only provide a temporary fix.  The root cause should be identified or the DPF will once again become blocked. A blocked DPF will always require investigation to understand why regeneration is not taking place. Our state-of-the-art vans and the remote diagnostic centre provide the very latest cutting-edge technology that is heads and shoulders above any local private garage.

DPF failure FAQ:

Short journeys, clogged EGR Valve increasing diesel soot passed to the DPF, faulty fuel injectors sending too much fuel to the air/fuel mixture, incorrect engine oil upon servicing the car – (Low Ash + Low Sulphur required for DPF Cars), turbo failing with oil dripping into the DPF and high mileage car that will find regeneration harder.

You feel a loss of power in your engine (limp mode), The DPF light will appear on your dashboard, passive and active regeneration keeps failing.  A strong smell of diesel, automatic Stop-Start System not Working and your car seems to be releasing an excessive amount of smoke.

During active regeneration you may notice the following symptoms; Increased idle speed, deactivation of automatic Stop/Start, a slight increase in fuel consumption, engine note change.

  • Loss Of Power / No Throttle Response
  • Warning Lights On Dash
  • Poor Fuel Consumption
  • Hard To Start & Slow Pick-Up In Speed
  • Limp Mode (Will does not rev over 3000RPM)
  • Engine Starts & Cuts Out
  • Engine Fails To Start
  • Turbocharger Faults
  • EGR Faults
  • Injector Leak
  • Engine Seals Leaking
  • Complete Engine Failure

vehicles engage active regeneration, which is the process of removing the accumulated soot from the filter by adding fuel post-combustion to increase exhaust gas temperatures and burn off the soot.

To clear the DPF, the soot needs to burn away, which is called “regeneration”. There are several ways that DPF regeneration can happen:

Passive regeneration: This happens naturally when the car gets hot enough, during long drives at a high speed, however, if you are getting symptoms of blocked DPF you will need forced regeneration.

Active regeneration: This is a process that your car can initiate in response to a blockage. Your car injects diesel on the exhaust stroke so that it ignites and burns the soot. However, if you are experiencing limp mode then you will need forced regeneration an area, we specialise in.

Forced regeneration: We carry out a forced regeneration where flush the soot off for you. This can only be done four times before it damages the filter permanently. This is done once the filter becomes very blocked and the car goes into limp mode.

It takes time for a DPF to block, sometimes years. Once blocked though, turbo failure can occur very quickly. If you don’t check for a DPF issue when installing a replacement turbo, there is a very high chance the replacement turbo will suffer the same failure, as it will be subject to the same operating environment as the previous unit.

DPF sensors are used in your diesel car’s exhaust system in order to help minimize the amount of soot, which is emitted from your car. That’s important not just for your car, but for the environment too. By filtering the diesel particulates, your car helps to cut down on the black smoke which is often seen billowing out the back of older diesel cars or vehicles which have a broken or faulty DPF sensor

Diesel particulate filter (DPF) is a filter that captures and stores exhaust soot, in order to reduce emissions from diesel cars. Because they only have a finite capacity, this trapped soot periodically has to be emptied or ‘burned off’ to regenerate the DPF. This is done by specialist equipment that we have on our fleet of vans.

Below are some common generic fault Codes:

  • P2452 – Particulate Filter Differential pressure sensor malfunction
  • P2453 – Diesel Particulate Filter Differential pressure sensor malfunction
  • P2454 – Diesel Particulate Filter Differential pressure sensor voltage too low
  • P2455 – Diesel Particulate Filter Differential pressure sensor malfunction
