How do you clear a particle filter?

Warm up the engine to operating temperature, then drive it for 15 minutes at constant speed on a motorway. Aim to keep the revs above 2000rpm for this period. The heat generated will help clean the DPF filter and the cars Regeneration cycle will usually kick in under these circumstances.

How long do DPF filters last?

around 100,000 miles

How do you force a regeneration?

A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.

Why does my DPF keep regenerating?

Your DPF will become blocked when soot builds up in it. 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.

Can you drive with a blocked DPF?

Can you ignore the DPF light and carry on driving? Technically yes, but we would not recommend it. If you ignore the DPF light and continue driving, the build-up of soot will soon reach a point whereby your car has to enter ‘limp-home’ mode in order to prevent any damage to the engine.

How far do you need to drive to clear DPF?

Because the DPF is under the car, not ‘close coupled’ in the exhaust manifold, the car needs to be driven quite a long way (50 miles) at 2000 – 2500 rpm to get the DPF hot enough to promote a passive regeneration.

How do I know if my DPF needs cleaning?

What Are The Signs Of A Blocked DPF?

1. You feel a loss of power in your engine (limp mode).
2. The DPF light will appear on your dashboard.

4. A pungent smell of diesel.
5. Automatic Stop-Start System Not Working.
6. Your car seems to be releasing an excessive amount of smoke.

How often should DPF be cleaned? The frequency with which you should clean your DPF depends on various factors including the manufacturer specifications, duty cycle, and condition of your engine. Generally, it’s recommended that a DPF be cleaned roughly every 150,000-200,000 miles.

Can I remove my DPF filter?

While it’s not illegal to remove a car’s DPF, it is illegal to drive without it if one should be fitted. The process for removing a DPF is a relatively simple one that requires cutting a hole in a vehicle’s exhaust, removing the filter and welding the resultant hole shut.

When should I clean DPF?

How often should you clean a DPF filter? Typically to keep your DPF working at it’s most efficient and reduce the risk of harmful materials getting into your engine, we recommend cleaning it every 6-9 months.
