Come across these today on the web after I got my DPF light on, first time ever! Quickly cleared it with a 20 mile drive on M11 doing over 2k at about 70mph in fifth gear. How PowerMaxx DPF Power Clean - High Power Cleaner for Diesel Particle Filters Works The JLM diesel particulate filter cleaner is available in 2 versions. Diesel Partikel filter Reiniger gibt es in 2 versions. Diesel roetfilter reiniger is er in 2 versies. Just wanted to know if anyone has used this stuff. It says to add into tank before filling up and should last between 3-6 months. Apparently it helps burn soot at lower temperatures and helps regeneration a lot easier and keeps the DPF cleaner and last longer! Considering the DPF problems on 140's and especially 170's with a remap, maybe it is worth giving it a try? What is everyone's thoughts and opinions?
