Diesel Particulate Filter Cleaning (DPF Cleaning)

As you are reading this page you are probably one of the many people that contact us every day with a blocked Diesel Particulate Filter (DPF)

Instructions on How To Clean The DPF Yourself

If you are unable to clean the DPF yourself, we can help you

The good news is that if after following the instructions on the above link, you still have a problem with your DPF, we can solve the problem for you.

We can identify the cause of your DPF becoming blocked, this is a chargeable service. Most garages cant do this as they dont have the knowledge, experience or correct diagnostic equipment to check the car properly, often there are no error codes (apart from one or more that say the DPF is blocked, which is at this point obvious) We check the live data and the calibration of all the sensors and determine if they are reading the actual pressures for example.

Determining the actual cause of the DPF not cleaning is one of the most important steps in the process, if the problem isnt resolved then the problem will be back again in about 2 weeks or less. Remember that the DPF is supposed to fill with Soot, that is not the problem, the problem is that the DPF is not able to clean itself, this is the real problem.

We can then fix the problem, you will be advised of the cost before we proceed with any repairs that may be necessary.

We can then Clean your DPF if necessary, occasionally cleaning is not required, the DPF can sometimes clean or regenerate itself once the cause of the problem has been resolved..

Our Specialist DPF Cleaning Process

The cause of the failure of the DPF to not  self-clean will be determined and advised and the cost of repair will be made clear to you before proceeding with the repair or cleaning of the dpf, so you will normally have a cost of one hours labour before deciding to proceed further.

Diagnosing what has caused the DPF to become blocked and fail to regenerate or self-clean is a chargeable service at £90.00 per hour, we can normally diagnose most problems within an hour, any problems advised MUST be rectified BEFORE we will clean the dpf. This will prevent the problem reoccuring.

The cleaning method that we practice allows even the most badly sooted DPF's to be cleaned and the vehicle returned to its normal working condition. 

We clean the DPF with the application of a Specialist Trade Only DPF cleaner from which is injected into the DPF Capsule in the vehicle exhaust system, the cleaner is left to soak and soften the soot and residue, the DPF and exhaust system is then flushed with a unique flushing agent that removes all of the soot and cleaning products from the DPF filter itself.

DPF CLeaning & Flushing Products


We recently had a 2009 model year Audi TT in our workshop where the soot level in the DPF was so high that the vehicle remained in limp mode, the soot level was actually higher than the maximum level that can be seen by the engine ecu, we cleaned the EGR valve, which was the cause of the excess sooting, then cleaned the DPF, cleared the stored values and took the car for a short run, (about 5 miles) the soot level was reduced to zero and the car performance was restored to its normal level. This particular vehicle had been to a number of dealers who reported that replacement at a cost of £1,700.00 was the only option available.

We can also offer advice and specialist products that can reduce the build up of soot in the first place, just ask when you bring your vehicle in for further information.

We can usually offer DPF Cleaning as a same-day service which normally takes about 2-3 hours, any further remedial work that is required will obviously take longer and is subject to parts availability but can be discussed at the time.

You are probably aware that many Diesel Particulate Filters (DPF's) cost close to £1000 or even substantially more, so our specialist DPF Cleaning service is sought by car owners from all over the country, often travelling great distances to take advantage of the specialist cleaning service that we offer. This is not really a while you wait service so many customers go for a stroll in the surrounding countryside or sight seeing in the historic City of St Albans while their car problems are solved.

We are happy to arrange a convenient appointment for you, often on the same day, to help you resolve the problem with your vehicle in a cost efficient, fast and easy to use service.

As diagnostic and auto electrical specialists we are also able to offer advice and assistance on any other problems you are having with your vehicle when you visit.
