- Passive and active regeneration keep failing.
- A pungent smell of diesel.
- Automatic Stop-Start System Not Working.

How much does it cost to clean a diesel particulate filter?
How much does it cost to clean a DPF filter?
| Low cost | Average cost | |
|---|---|---|
| DPF cleaning | $85-$100 | $195.50 |
Can a blocked DPF damage turbo?
A blocked DPF can force exhaust gas through the smallest of gaps, including the clearances in the bearing housing VNT lever arm and turbine housing waste gate mechanisms. If this occurs, carbon build up in these mechanisms can restrict movement of the levers affecting performance of the turbo.
Can a fully blocked DPF be cleaned?
Some garages can clean blocked DPFs, in a process called forced regeneration. This usually costs around £100 and, while it’s not a 100% guaranteed fix, it’s usually successful in removing the excess soot and allowing the DPF to work and automatically regenerate again.
How can I clean my DPF without removing it?
Can I clean DPF myself?
Driving without a DPF is illegal in many locations and a vehicle without one won’t pass inspections. The only time that a DPF can be removed is for repair work by a qualified mechanic. Never attempt to remove the DPF to repair it yourself, as this requires extensive, expert knowledge and equipment.
How do I clear my DPF while driving?
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.
Is a DPF expensive to replace?
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!
Can you drive with a full 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.
Can a fully blocked DPF be cleaned?
Can you clean a DPF? (Diesel Particulate Filter) – Yes, you can. DPF cleaning is one of the most commonly-requested services now amongst our 500+ TerraClean dealers. Many of our dealers actually provide this service to neighbouring garages who need to have their customers’ vehicles’ DPFs cleaned.
What do you do when your diesel particulate filter is full?
When you first see the light, you can resume normal driving, but when you get a chance, take the car onto the highway and drive it for around 10 minutes at 40+ MPH. This should sufficiently raise the temperature to levels high enough to regenerate the filter, and hopefully the light will turn off.
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.
How do I stop my DPF from clogging?
The soot can block the filter, stopping the engine from running and leaving you with a repair bill running into the thousands. To stop this from happening, the soot needs to be burned at a high enough temperature to turn it into smaller ash particles, which can then be expelled from the system.
What happens if you don’t clean DPF filter?
If the soot trapped by a DPF is not removed regularly, the filter can’t work properly. This results in a vast build-up of soot. When the DPF is cleaned, the excess soot is burned off. This lowers dangerous emissions and will reduce the amount of black smoke emitted by your vehicle.
What is the best way to clean a DPF filter?
Does premium diesel help DPF? Not so much in the fuel system, but in the combustion area, emission components (EGR, DPF), and intake manifold, intake valves, etc. Using a premium diesel will undoubtedly delay the formation of carbon deposits in these areas.
How often does a DPF regenerate? Active regeneration will be initiated every 300 miles or so depending on how you use your car and will take 5 to 10 minutes to complete.
How do I know my DPF is regenerating?
You will know whether active regeneration is taking place by the following symptoms:
- Engine note change.
- Cooling fans running.
- A slight increase in fuel consumption.
- Increased idle speed.
- Deactivation of automatic Stop/Start.
- A hot, acrid smell from the exhaust.
How do you clean a DPF while driving?
If your car has an automatic transmission, shift your gears in a manual mode by moving the gear shift gently. No need to use the speed limiter, it is with no seeming value added. Ride like this for a minimum of 30 minutes. This will initiate a regeneration cycle, and your DPF will be cleaned.
How does a DPF clean itself?
During normal working condition the diesel particle filter will clean itself regularly by self-regeneration. After each regeneration-cycle, some ash are left in the filter and cause shorter regeneration interval. This means that each DPF will need service sooner or later.
How do you unclog a DPF filter?
Can a blocked DPF cause power loss?
Problems. A blocked DPF can cause many problems including loss of power, economy and throttle response. With more extreme cases, filters that are extremely blocked can cause the engine not to start at all.
What happens to engine if DPF is blocked?
Because a DPF blockage directly affects your exhaust system and its ability to remove gas from your engine, this then stops your engine from working as powerfully and as efficiently as it could. This in turn makes the diver heavier on the gas, which burns through fuel quicker and contributes to the engine suffocation.
How do I know if my DPF is regenerating?
So how do you tell that your engine is performing an active DPF regeneration? One signal to look for is your cooling fans running at a higher capacity than normal, or the sound of your engine may change note. Sometimes, a hot and pungent smell can also start coming from your engine as the soot is being burned away.
Can you clean DPF by driving? If your car has an automatic transmission, shift your gears in a manual mode by moving the gear shift gently. No need to use the speed limiter, it is with no seeming value added. Ride like this for a minimum of 30 minutes. This will initiate a regeneration cycle, and your DPF will be cleaned.
