    TUNAP has this week urged garage owners and technicians to question if DPF cleaners remove both the soot and ash content from inside blocked diesel pa

    I’m interested in looking at the proof that the tunap product can dissolve ash enough to turn it into steam and smoke seeing as ash is the waste product of the regeneration process I’m quite sure this is not possible so I think this is misadvertising I look forward to your responce

    Hi Brett, Thank you for your interest regarding our DPF cleaner and the ability of our cleaner to remove ash as well as soot. I can confirm that our cleaner unlike our competitors products does remove ash. This is a major benefit as this extends the life of the filter. We carry out testing with our manufacturer partners unfortunately these tests cannot be made available. We do have independent testing with DINEX that also confirms a significant reduction in the ash content in the filter following a clean using the TUNAP DPF cleaning system. Please can you get in touch and give us your contact details so I can organise one of our field team to make the DINEX report information available for you to confirm the results of the ash reduction. Thank you once again for your interest. Andy Trafford

    I’m a sceptic when it comes to the claims of products like this. I don’t doubt that soot removal is possible, but when it comes to the ash, I very much doubt it. Please surprise me. Steve

    Hi Steve,
    Please give me your contact details and I will organise one of our field representatives to contact you and show you the test results. Andy Trafford

    I am interested in this “Technology” and your claims that this procedure dissolves and removes ash, but you seem to be short on details as to how this occurs, I understand the patenting concerns you might have with a new product but the mechanisms that are chemically created need to be explained , for example verified readings can be taken from VCDS diagnostics on a VAG diesel using individual block advanced measurements giving soot and ash content , all you need to do is get readings from VXDS BEFORE THE PROCEDURE THENN AGAIN AFTER THE PROCEDURE and have this verified by independant parties .
    sadly the fact that (perhaps conveniently) the results of your tests carried out with manufacturers cannot be made available suggest a snake oil product . I dont wish to be harsh but if you have something that really works you should be informing your potential customer base of how it actually works, and give your product a proper chance of success when you launch it, it just smacks of another “Miracle Hair restorer” story otherwise. I would say shout it from the roof tops if this product really does what you say it does. Kind Regards John

    Hi John, thank you for your interest. The reports following the tests from manufacturers and independent testers are quite detailed and cover lots of parameters not just the ash. As I have offered in my previous replies, please give me your contact details and I will arrange for on of my Technical Products Specialists to visit you and go through the results from the testing. I hope that you will then confirm the results as an independent garage wire reader. I look forward to hearing from you. Andy Trafford

    John, the ash values reported by VCDS are calculated values based on fuel consumption and distance driven, and do not reflect the actual mass of ash in the filter (which might be a lot more or a lot less than the calculated value). Because of that those readings will never decrease, even then not, if you remove the old DPF and install a completely new DPF filter in its place. You can only reset those values manually in the ECU – but again, the engine has no way of knowing the actual mass of ash, and only uses these values as reference data.
