* QUESTION, Does DPF on car cleaning honestly actually work?
* ANSWER, Yes the latest release of the foaming chemical works extremely well if used by a professional with a compressor and experience of how to use the application process correctly. It has been very successful for us on our latest cleans in the last approximately two years.

* QUESTION, Is the carbon cleaning thing that people offer actually work?
* ANSWER, Strictly my opinion and without prejudice, from what I have seen from professionals using this method, all I can say is that the cleans that I have seen might clean the engine internally and the EGR valve, I don’t know, but their results showed no cleaning affect at all on the DPF filter. Also if it had been seen to have worked, we would have one in our toolbox.

* QUESTION, How much does the cleaning fluid cost?
* ANSWER, Get real – that is a trade secret, but what I will say is this, on the professional use market there are good and bad and some very bad with varying price tags. We only use the very best tried and thoroughly tested.

* QUESTION, Where do you carry out your mobile DPF filter cleaning?
* ANSWER, We cover all of Greater Manchester and North Cheshire at your home or fixed place of work or a motorhome storage park. We do not visit temporary campsites or building sites.

* QUESTION, How long does the DPF filter cleaning process take?
* ANSWER, It depends on the location of the DPF filter itself and the back pressure sensor. On many cars and vans, also motorhomes, they are located under the vehicle and not accessible so we raise the vehicle up on hydraulic ramps for safe access. But on average, including the full diagnostics session and then cleaning, it is 2 hours and 30 minutes on average.

* QUESTION, Can all DPF filters be fully cleaned to a clean enough condition to work properly as it should?
* ANSWER, In some circumstances, depending on the mileage of the vehicle and the driving style it has been driven in i.e very regular motorway driving for at least 40 minutes so it can clean itself, then no as the filter will reach a stage of what in the trade is called solidified with ash which turns part of the filter or even all of it into what would resemble a building concrete breeze block as I can only describe it as. In this case yes it will clean but only partially so. It will not rectify the gas flow rate and back pressure problem either at all or definitely not long term. I hope this answers your question.

* QUESTION, Is it illegal to remove a DPF filter from my van.
