You’ve seen this message in your Ford Focus and are now wondering: What does it mean and what do I need to do? Don’t worry, you’re not alone! Many Ford Focus drivers see this message and are unsure.
“Exhaust filter full” means that the Diesel Particulate Filter (DPF) in your Ford Focus has accumulated a certain amount of soot and needs regeneration. The DPF is an important part of modern diesel vehicles, ensuring that harmful soot particles do not enter the environment.
The message “Cleaning drive” means that you need to drive your vehicle under certain conditions so that the DPF can clean itself.
What is a DPF Cleaning Drive and How Do I Perform It?
In a DPF cleaning drive, also known as regeneration, the accumulated soot in the filter is burned off at high temperatures. Certain conditions must be met for this to happen, such as:
- Vehicle Temperature: The engine must have reached operating temperature.
- Engine Speed: The engine must run at a minimum of 2,000 revolutions per minute for an extended period.
- Driving Duration: The cleaning drive should last at least 20-30 minutes.
How to perform a DPF cleaning drive:
- Drive onto the highway or a well-maintained country road.
- Maintain a constant speed of approximately 60 mph (at least 40 mph).
- Keep the engine speed above 2,000 revolutions per minute (pay attention to the appropriate gear).
- Continue driving in this mode for at least 20-30 minutes.
Important: Do not interrupt the cleaning drive, as this can lead to further filter clogging.

What Happens If I Ignore the DPF Cleaning Drive?
If you ignore the message “Exhaust filter full Cleaning drive Ford Focus” and do not perform a cleaning drive, this can have serious consequences:
- Loss of Performance: The engine may go into limp mode to prevent damage.
- Increased Fuel Consumption: A clogged DPF increases back pressure in the exhaust system and leads to higher fuel consumption.
- Expensive Repair Costs: In the worst case, a clogged DPF can no longer be regenerated and must be replaced.

Tips to Avoid a Full Diesel Particulate Filter
- Avoid Short Trips: On short trips, the DPF cannot regenerate sufficiently.
- Use the Correct Engine Oil: Pay attention to engine oil with the “Low SAPS” specification, as this reduces soot formation.
- Refuel with Quality Diesel: Ensure you use high-quality diesel fuel.
