The main reasoning behind DPF fault lights are due to soot building up in the exhaust. This could be caused by the driver only making short journeys or there could be a sensor fault or wiring fault stopping the DPF from functioning correctly. When the DPF is blocked by soot, the dashboard then shows an illuminated light. Usually if you drive long distances, as a driver you can perform the passive process to allow the DPF to unblock itself.
DPF and ABS Light Faults
At Cardiff Auto Electrics, we have the experience and equipment necessary to diagnose and repair faults with the DPF.
ABS stands for anti lock braking system, and if the ABS warning light is illuminated in your car’s gauge cluster, that means the antilock system has been deactivated because of a malfunction.
Your car’s regular brakes should work fine, but the anti lock feature that prevents wheels from locking up during braking will not work. In addition, if your vehicle has stability control and traction control, those will be disabled as well because those systems rely on the same wheel-speed sensors as the antilock system.
All 2012 and newer vehicles are required to have stability control, so they also have ABS and traction control. Many older cars also have some or all of those features.
The ABS light (usually yellow, amber or orange) should come on briefly every time you start your car as part of a system check. If the light stays on, that means something isn’t working and the system has been shut down. We would advise you to book in for us to check and diagnose the issue.
