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

Easy to use. Van now working as is should.Cheaper than the £265 I was quoted for a professional clean. Probably not the same level of cleaning, but did the job.

Good stuff

Seems to do what it says on the tin. Easy to use.

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.

Absolute junk, Does not work.
