Microscopic soot particles are inhalable and can affect respiratory conditions such as asthma, bronchitis and emphysema. Reducing the level of diesel soot particles being emitted improved air quality; and therefore, is beneficial to good health.
Diesel vehicles are required to be fitted with a Diesel Particulate Filter (DPF) in the exhaust system, to reduce emissions. DPF control software is incorporated into the Engine Control Module (ECM). When you drive, the particles in the exhaust gases collect in the filter. The DPF software monitors the level of trapped particles. To prevent obstruction to the free flow of exhaust gases, the DPF cleans itself by burning off the particles at high temperatures.
If you regularly drive in city of urban traffic, the particles build up more rapidly. When the amount of trapped particles has increased, the sensor will send a signal to the ECM to request regeneration.
An amber warning light illuminates and is accompanied by a DPF message in the message centre of your Land Rover’s dash. As such, you will need to drive steadily at approximately 40 – 70 mph to allow the particles to be burnt away. The regeneration process will take between 10 and 20 minutes to complete. Once completed, the amber warning lamp extinguishes.
If regeneration is not successful, the amber warning light is replaced with a red warning lamp. If this occurs please contact your local Beadles Land Rover retailer for advice and assistance.
Due to the high temperatures reaches, the materials within the DPF will expand and contract. This expansion and contraction can produce noises which may be audible when exiting your Land Rover – please be assured this is completely normal.
For any further information on Diesel Particulate Filters, please call your local Beadles Land Rover retailer and a member of the team will be happy to assist you.
