WHAT YOU NEED TO KNOW ABOUT THE DPF
The DPF (Diesel Particulate Filters) can reduce pollution coming from your vehicle, here are the facts below.
Diesel produces lots of soot (particulate matter) that can cause respiratory problems and contribute to the risk of cardiovascular diseases. Modern diesel cars (since 2009) have to be fitted with a DPF in the exhaust to stop this soot from passing into the atmosphere. The aim is to cut 80% in particle emissions but the technology’s not without problems.
To maintain performance a DPF has to be emptied regularly. This is usually done passively in a process called ‘regeneration’ when the exhaust temperature’s high enough, on motorways or fast A-roads.
The collected soot is burnt off, leaving only a tiny ash residue. A DPF if used correctly should be good for well over 100,000 miles.
