Will a blocked DPF cause smoke?
If there is black smoke leaving your exhaust pipe, this is an obvious indicator that your DPF filter is not working properly. Like any filter, your DPF will, over time, start to form a blockage from the waste that it holds and will need to be cleaned.
Does AdBlue keep DPF clean?
AdBlue favours regeneration cycles, so it participates directly in the maintenance of the diesel particulate filter. However, so that the diesel car’s emission control system to work properly, it is necessary to make long trips (a minimum of 30 minutes) by regularly pushing the gears.
What happens if the DPF is not working properly?
If theses are not working effectively it can potentially speed up the DPF blocking. Failed Regeneration – For the DPF to regenerate there are certain conditions to be met. If these prerequisites are not met the DPF will fail to regenerate. See here for more info – http://wiki.ross-tech.com/DPF
Where does the DPF go in a diesel car?
What is a DPF? The Diesel Particulate Filter is in the exhaust system of all diesel-powered cars sold new since 2009. It is a vital component that is designed to enable cars to pass increasingly tough emissions legislation.
How does a car clear a DPF blockage?
To clear it, the soot needs to burn away, which is called “regeneration”. There are several ways that DPF regeneration can happen: Passive regeneration: This happens naturally when the car gets hot enough, during long drives at a high speed. Active regeneration: This is a process that your car can initiate in response to a blockage.
What to do when DPF warning lamp comes on?
When the DPF warning lamp comes on (check your handbook to see exactly what the one on your diesel looks like) it’s time to take the vehicle on a longer run, preferably on a faster road such as a dual carriageway or motorway.
When to empty the Diesel Particulate Filter ( DPF )?
The aim is an 80% cut in particle emissions but the technology’s not without problems and our patrols are often called to cars with a blocked DPF. 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.

What happens when you ignore a DPF warning light?
If you ignore a DPF warning light and keep driving in a relatively slow, stop/start pattern, soot will build up in the filter until your car goes into ‘restricted performance mode’ to prevent damage. If you let it get this bad: Driving at speed alone won’t be enough.
Are there any problems after removal of DPF?
So far this may seem very tempting, but a problem is looming, and it can be a very serious one, which although unlikely, can leave you open to the risk of a criminal conviction.
