How do I fix my Diesel Particulate Filter warning?
What do you do when you see the DPF light? When the DPF light has become illuminated, it’s telling you that ‘passive regeneration’ has failed and that you need to actively regenerate the diesel particulate filter. You can do this by increasing your speed to more than 40mph for between 10 and 15 minutes.
How do you clear a DPF warning light?
If you get a warning light showing that the filter’s blocked, it should be possible to complete an active regeneration cycle and clear the warning light by driving for 10 minutes or so at speeds over 40mph.
How do I know if my DPF is bad?
Here are some signs that indicate the DPF is not regenerating properly due to the DPF sensor failing:
- Poor engine performance.
- Poor fuel economy.
- High engine temperatures.
- High transmission temperatures.
- An increase in black smoke (soot) from the exhaust.
- Check engine light.
Is removing DPF a good idea?
While it’s not illegal to remove a car’s DPF, it is illegal to drive without it if one should be fitted. Removing the filter doesn’t affect the car’s performance, and some motorists even state they achieve better fuel economy and engine performance without one.
Can I clean a DPF myself?
Don’t DPFs clean themselves? In theory, yes. “Passive Regeneration” or if appropriate Active DPF regeneration will take place as part of a healthy diesel engine running cycle, but active regeneration can fail once a blockage reaches a certain level. Sometimes a “forced” regeneration may be carried out by a mechanic.
How do you clean the DPF on a motorway?
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 should a DPF filter last?
How long should a DPF last? A DPF can last up to around 100,000 miles if maintained properly.
How do you manually regenerate a DPF?
To kick off a manual DPF regeneration you should
- Put the vehicle in neutral.
- Put on the hand brake.
- Leave the pedals alone!
- Press and hold the DPF button for 2 seconds or longer.
Can you regen a truck while driving?
The short answer is, Yes! If you keep driving your truck without doing a parked regen your truck will enter a derated mode. An active regen is when the truck does this process automatically. This happens when the soot reaches a certain threshold and starts the active process to burn the soot off.
How much does it cost to replace DPF filter?
Replacing a DPF can easily cost $4000 to $8000, and sometimes more, it’s a big cost … particularly when a vehicle is out of warranty!
How much does it cost to clean a DPF filter?
➢ Prices charged for DPF Cleaning range between $350 and $500, depending on location and cleaning method used. ➢ Some manufacturers offer exchange programs in lieu of cleaning, which usually run between $600 and $800.
Can a blocked DPF damage the engine?
Driving the vehicle with a blocked DPF can seriously damage your engine / turbo and it’s not uncommon to have to replace a turbo when the warning light has been ignored for extended periods. The ash residue which remains after successful regeneration cannot be removed and will eventually fill the filter.
Can you drill holes in a DPF filter?
Drilling holes in substrates of diesel particulate filters to make exhaust gases flow more freely through the honeycomb structures. This defeats the purpose of the DPF, which is to remove soot from the exhaust, and affects reliability of the devices, noted Kevin Otto, service director for Cummins Emissions Solutions.
Does removing DPF affect mot?
The most significant area for diesel car owners is stricter rules on the permissible level of emissions of cars fitted with a DPF. If a car’s exhaust emits visible smoke of any colour, it will fail the MOT test. It’s already illegal to drive a vehicle that has had its DPF removed.
Does removing DPF cause black smoke?
There are companies that remove the DPF permanently and professionally and will cause MOT to fail. The DPF is designed to remove the ‘soot’ from the exhaust gas of a diesel engine. A diesel car or van equipped with a functioning DPF filter will emit no black smoke from its exhaust pipe.
