NorthernNavara

Hi all, It's my first post here so please go easy on me! I've just collected a 2007 Nissan Navara which I think has a DPF problem, it's struggling under load when going up hills etc. I've found this article which outlines some of the best DPF cleaners to buy, has anybody used any of these and if so have they given good results? https://www.buyersguides.uk/best-dpf-cleaners/ Thanks in advance
