JLM Diesel Particulate Filter (DPF) Cleaner | Car Engine Additive Spray, 400ml (J02220)

The JLM DPF Cleaner is one of those products that actually delivers on what it promises. It’s very straightforward to use just spray directly into the DPF through the sensor hole and the difference it makes is noticeable. After using it, the engine ran smoother, and the warning light cleared much faster than expected. It’s ideal for anyone dealing with a partially blocked DPF or wanting to prevent issues before they start. The spray application is convenient and far less messy than pouring additives into the fuel tank. You can tell it’s a professional-grade product; it feels like something mechanics would genuinely recommend. Overall, an effective and easy-to-use cleaner that can save a lot of hassle and money in the long run.

This product has got me out of trouble and an expensive bill in the garage. Instructions are straight forward and cleans out the dpf removing the engine light.

Last time my DPF got blocked I paid £200 for a chap to come and clear it. This time I used this product and it appears to have done the job. However two caveats: I had also bought a TopDon diagnostic tool capable of clearing errors and performing a forced regen, I'm not sure how successful I would have been without that. Secondly there were no instructions whatsoever on the can or an included leaflet and you really need to know what you're doing, so because this is aimed at the home user that is definitely 1 star off.

Not many motorists know that one can specifically target the DPF with a cleaning fluid like JLM DPF Cleaner Spray injected with the DPF in place, without needing to go through the fuel tank and the (entire) fuel system. This will not risk causing any unwanted damage to the injectors, fuel pressure pumps, sensors, turbocharger, seals, catalytic converters and so on. With this method the cleaner goes only where it needs to go, there it does the job and then leaves through the tailpipe. One only needs to find a way/port into the DPF depending on the specific engine/system, via the back/exhaust pressure sensor pipe, or the pre-DPF side of the two lines attached to the differential pressure sensor. Once injected, the cleaner needs to be left for about a quarter-hour to sit and dissolve the soot and deposits. following that, the engine will need to be taken for a drive on the highway for at least half-an-hour or the engine will need to be revved up to about 3k revolutions/min for around ten minutes. There will be smoke and foam at the tailpipe, but that is normal for the operation. This method will eventually unclog a blocked DPF or will improve flow through one, reducing DPF regeneration temperatures (and frequency). A slightly more advanced diagnostic tool may be needed to reset fault codes and possibly tell the system that a new DPF has been fitted.

i would not use this again, was a total waste of time, my renulat traffic had 52grams of soot in the system when i started, after i had used both tins and took a test drive it then had 62grams of soot. id advice using Mannol DPF Cleaner Diesel Particulate Filter with Probe 500 ml, link here cheaper and had better results

The actual item was excellent But took 3 days to track it down as it had been left at the wrong address So would not blame the seller

Fabulous product. My car is gleaming

Used in conjunction with JLM diesel additive.Ive done 5 ,000 miles up to now with DPF behaving.
