dpf Deep Cleaning & solutions


dpf Cleaning

There are probably hundreds of thousands of vehicles out there today with some sort of DPF issue. Deep cleaning the DPF while still fitted to the vehicle is a cost-effective way of eradicating expensive replacements & vehicle downtime.

The upside of DPF Cleaning is that it is much cheaper – We can come to you to carry out the necessary work – We also tell you what is causing the DPF to fail for example EGR issue, boost leak or just not getting a chance to self clean

The DPF Deep Cleaning

This article we will discuss the problems with DPF filters and what we can do to rectify the problem as well as how to maintain your vehicles DPF Filter. We hope you find this article helpful and of course if you have any question please get in contact.

There are lots of problems and checks that need to be addressed before a DPF can be cleaned. If you decide to have your DPF cleaned or removed completely from your vehicle you must be aware of the follow MOT law.

Stricter rules for diesel car emissions

There are stricter limits for emissions from diesel cars with a diesel particulate filter (DPF). A DPF captures and stores exhaust soot to reduce emissions from diesel cars. Check your car’s handbook if you don’t know if your car has a DPFYour vehicle will get a major fault if the MOT tester: can see smoke of any colour coming from the exhaust and finds evidence that the DPF has been tampered with.

Cleaning Procedure

Once you have made the conscious decision to have the DPF Deep Cleaned we must follow the following set of rules:

  1. We always scan the vehicle for any DPF or non-related fault codes.
  2. We also monitor the DPF pressures at idle as well at 3000rpm to establish how blocked the DPF is.
  3. Once we have assessed how blocked your DPF is we can then go ahead and start the cleaning by using the very best environmentally friendly chemicals out there today.
  4. We introduce the cleaning chemical into the front of the DPF through the pressure side of the DPF pressure sensor pipe work. We introduce the chemical at a pressure of 130psi whilst the engine is running.
  5.  Once all of the chemical is loaded into the DPF we wait for 5 to 10 minutes for the chemical to get to work breaking down the carbon & soot build up inside the DPF causing the blockage. 
  6. We then reassemble the sensor pipe work and start the engine, we take the engine rpm up to 3000rpm and force out the chemical through the DPF thus cleaning it. We also monitor the DPF pressure to make sure the pressure is being relieved from the DPF itself. Once we are happy that the pressures are within tolerance and the soot levels have dropped to the correct levels we are complete.
  7. We then reset the DPF to tell the vehicle that the vehicle has had new new DPF we can now do this as the DPF is in like new condition again.



Common Faults With DPF Filters

The most common faults are either:
  • Faulty Sensors
  • Fully blocked DPF because the car has not been able to conduct a full regeneration.
  • Eoyls tank is empty if fitted.
  • Pressure differential pipe work split.
  • The most missed on is that the DPF is just full of ASH!

Guide To Cost's

The price list is as follows:
  • DPF Deep Clean £300
  • DPF Static Regeneration only around £100-£150
  • Hydrogen Carbon Engine Cleaning (Hydro Clean) of the DPF £150.
  • DPF Replacement is between £1200 to £3000+

Preventative Measures

There are a few preventative measures that can be taken to stop your vehicles DPF from becoming prematurely blocked they are as follows:

  • Drive the vehicle up and down the motorway and get the DPF into a natural state of regeneration at least once a week.
  • Try to use a high fuel grade maybe 1 in every 3 tank fills.
  • Have a maintenance DPF Deep Clean once a year or every 30k miles
  • Regularly conduct a Hydrogen Carbon Clean.
