Diesel particulate filter specialists
Your car’s Diesel Particulate Filter (DPF) sits in the exhaust system and filters harmful carbon particulates produced in the combustion cycle, preventing these particles from being released into the atmosphere.
First fitted to diesel vehicles in 2007, the DPF has been causing confusion and, in many cases, expensive repair bills for drivers due to a lack of knowledge about the system.
The filter is designed to deliver an 80% reduction in diesel particulate and soot emissions by trapping the particles in the filter itself.
The engine control unit (ECU) monitors the saturation level inside the filter, and when it reaches a certain percentage, it increases the temperature inside the exhaust to ‘burn off’ the particles.
If your car’s DPF hasn’t regenerated and has become ‘blocked’ you’ll see a warning light on the dashboard and need to take your vehicle to a diesel mechanic immediately.
