Unlike the hi-temperature baking method, DPF Flushing Liquid reliably dissolves and removes all soot deposits and residue. The Flushing Liquid gently cleans and is safe for use with aluminum, magnesium, zinc and cadmium parts. These services are perfectly adapted for the latest generation of particulate filters.

Nick Molden, chief executive of Emissions Analytics, told the BBC: “The MoT test is clearly not fit for purpose in checking if a DPF has been removed", while Frank Kelly, professor of kKOWaj.
