Diesel particulate filter
Some of our customer have been experiencing issues with the diesel particulate filter (DPF) self-cleaning system. In conjunction with Vauxhall, our maintenance authorisation team are committed to try to keep you on the road and earning money. Any standard servicing items or warranty issues with your car will be dealt with promptly. In order to try to prevent any issues occurring and the potential inconvenience of your car being off the road we have produced the following FAQ.
- What is a diesel particle filter?
Diesel particulate filters (DPF) or ‘traps’ do just that, they catch bits of soot in the exhaust. The filter system includes a self-cleaning function that runs automatically to burn off the soot particles at high temperature. Diesel vehicles were required to be fitted with a DPF to meet new European emissions regulations from 2009 in a bid to reduce soot emissions in the environment.
- What is the issue with DPF?
If you are typically driving short distances and using low revolutions per minutes then the self-cleaning system may not automatically switch on, which causes soot to build-up and can lead to serious engine damage. A flashing symbol will display on your dash if the automatic cleaning is not enabled.
- How can I prevent this from happening on my car?
It’s important that you regularly drive above 2000 revolutions per minute for up to 20 minutes even if the warning light does not appear. We would recommend driving on the motorway at least once a week to achieve this to ensure the automatically cleaning system is enabled.
- What should I do if the flashing light is displayed?
You should follow the steps above immediately. Do not turn off the engine or interrupt the cleaning process until the light extinguishes on your dash.
- What will happen if I ignore the issue?
As part of your contract you have agreed to take care of your vehicle in line with the manufacturer’s service schedules and DPF maintenance. If you fail to follow the DPF advice and your car continues to show the flashing light, your car may go into ‘limp home’ mode and you will be responsible for the rectification costs, which can be up to £600 and you will not be eligible for a replacement vehicle.
If the following icon illuminates on your dash then this indicates the cleaning process is not possible and you must seek assistance at your nearest Vauxhall garage.
We will chase manufacturer warranty on your behalf at this stage, however, if the problem is caused by neglect then the fault and costs will be your responsibility.
