At Bsmart Autocentre we offer in-house DPF filter (Diesel Particle Filter) carbon clean service for your blocked DPF. DPF carbon clean is the best and most environmentally friendly way to clean and regenerate your car DPF.

What is a DPF filter?

DPF stands for diesel particulate filter and it’s main job is to trap soot which is created by a byproduct of the combustion process.

DPFs need to ‘regenerate’ to prevent clogging and this only happens when you drive for an extended period.

The DPF can start regeneration in a couple of ways, but both need the exhaust gases to get extremely hot — usually around 500 degrees Celsius, which is twice as hot as a domestic oven. ‘Passive regeneration’ takes place when you drive your car at speeds above 40mph for several minutes at a time, and doing this regularly should burn off the particulates in the DPF automatically.

If you don’t drive at speed often, the engine will try to clear the DPF via ‘active regeneration’. This is where the engine lets the exhaust gases get hot enough to burn off the soot without requiring the car to be run at a speed above 40mph.

Most cars have a two-stage warning system:

  • Amber light – you should be able to regenerate the vehicle by driving above 40mph.
  • Red light – trip to a garage

DPF’s or Diesel Particle filters were first introduced in 2008 on diesel vehicles. It was introduced to catch carbon particles.

If carbon content in the DPF exceeds a certain amount the car engine electronic system will not allow this generation and therefore at this stage you need a specialist garage to perform a full DPF carbon clean.

So there are a lot of reasons why your DPF has become blocked the most common is that carbon has been accumulating in your DPF over a period of time and due to little or no journeys travelling at over 60mph your DPF has reached a point where it can not self-clean or regenerate.

How long does it take for my DPF to be cleaned?

Bsmart can clean your DPF using our dedicated equipment which takes an average of 3-4 hours, this includes the removal of the DPF itself from your car. We will make sure it’s fully cleaned and regenerated.

DPF Cleaning Procedure outlined below:

  1. Remove the DPF from your car or van
  2. DPF is attached to the Carbon Clean DPF machine and cleaned using a non flammable detergent, air and water
  3. DPF is then fitted back onto the vehicle
  4. All diagnostic codes cleared, DPF data reset and regenerated

DPF Carbon clean uses special formulated detergents and compressed air which are both sent through the DPF preventing future exhaust and engine issues by flushing out all the carbon that has built up and any remaining ash from previous regenerations.
