Did you know that your local Autobahn service centre can inspect and diagnose your cars diesel particulate filter system!
Diesel Particulate Filter (DPF) is an emissions control device installed in the exhaust systems of diesel vehicles to reduce the emission of particulate matter (PM) and other harmful pollutants. Regular maintenance and proper driving habits can help prevent excessive blockage of the DPF.
A Diesel Particulate Filter (DPF) is an emissions control device installed in the exhaust systems of diesel vehicles to reduce the emission of particulate matter (PM) and other harmful pollutants. The DPF works by trapping and collecting soot and other fine particles produced during the combustion process in diesel engines. This helps to reduce air pollution and improve air quality by preventing these particles from being released into the atmosphere.
DPFs play a crucial role in meeting emissions standards and regulations set by environmental agencies. These standards are aimed at reducing the environmental and health impacts of diesel engine emissions, which can include harmful particles and gases.
Over time, the trapped particles in the filter can accumulate, leading to reduced engine performance and increased fuel consumption. When the DPF particulates are excessive or a predetermined cycle is reached, a process called “regeneration” is initiated. This process involves raising the exhaust gas temperature to burn off the trapped particles and regenerate the filter.
If regeneration is not successful or if the DPF is excessively clogged (can be indicated via tell-tale warning light illumination, and or lack of performance), it may require professional servicing or replacement. Regular maintenance and proper driving habits can help prevent excessive blockage of the DPF. This might include ensuring the vehicle is driven at sufficient speeds for extended periods, as this helps maintain the necessary exhaust gas temperatures for effective regeneration.
It’s important for diesel vehicle owners in Australia to follow manufacturer recommendations regarding DPF servicing and maintenance to ensure compliance with emissions regulations and to avoid potential issues with engine performance. Additionally, if the vehicle has a lack of performance or the DPF tell-tale light is illuminated, it’s advisable to consult with an Autobahn qualified technician for specific information about DPF servicing and or replacement.
An Autobahn professional technician can determine any issues or faults with your cars diesel particulate system and advise you on the best action to rectify the fault.
Did you know that your local Autobahn service centre can inspect and diagnose your cars constant velocity (CV/Drive-shafts) joints!
Constant velocity (CV) joints on cars is an important component of the vehicle’s drivetrain. CV joints are crucial components that allow the driveshaft to transmit power to the wheels while accommodating the up-and-down motion of the suspension.
Did you know that your local Autobahn service centre can inspect and diagnose your cars suspension system!
Suspension problems in modern cars, can affect the vehicle’s handling, ride comfort, and overall safety. A properly functioning suspension system is crucial for maintaining control, stability, and comfort while driving.
Did you know that your local Autobahn service centre can inspect and diagnose your cars tell-tale light warning system!
The tell-tale warning lights in modern cars serve a critical role in informing the driver about various vehicle conditions and potential issues… These warning lights are designed to provide timely and important information to the driver.
