DPF DIAGNOSTICS / HYDROSONIC DPF & INTAKE CLEANING
If your diesel vehicle has lost power, entered limp mode or has a DPF warning light illuminated, High Rollers 4x4 can help.
Our experienced technicians provide professional DPF diagnostics, hydrosonic diesel particulate filter (DPF) cleaning and intake manifold cleaning for a wide range of diesel vehicles. Using advanced diagnostic equipment and professional hydrosonic cleaning technology, we can accurately diagnose DPF-related faults and restore airflow and engine performance without immediately resorting to costly component replacement.
Whether you drive a 4WD, ute, SUV or commercial vehicle, we'll determine the cause of the problem and recommend the most effective solution for your vehicle.
WHAT IS A DIESEL PARTICULAR FILTER (DPF)?
A Diesel Particulate Filter (DPF) is an emissions control device fitted to most modern diesel vehicles. Its job is to capture and store soot particles produced during normal engine operation before burning them off during a regeneration cycle.
Over time, soot and ash naturally build up inside the filter. If regeneration cannot occur successfully, the DPF can become blocked, restricting exhaust flow and causing a range of performance issues.
Without proper maintenance, a blocked DPF can lead to expensive repairs and reduced engine performance.
SIGNS YOUR DPF MAY BE BLOCKED
A blocked or restricted DPF can cause several noticeable symptoms, including:
- DPF warning light illuminated
- Engine warning light
- Limp mode
- Reduced engine power
- Increased fuel consumption
- Frequent regeneration cycles
- Poor acceleration
- Excessive exhaust smoke
- Failed DPF regenerations
- Strong diesel smell
- Cooling fan running after the engine is switched off
If you've noticed any of these symptoms, it's important to have your vehicle diagnosed before the blockage becomes more severe.
PROFESSIONAL DPF DIAGNOSTICS
Before recommending any repairs or cleaning, we carry out a thorough diagnostic assessment to determine exactly what's causing the issue.
Our technicians inspect and test:
- Stored diagnostic fault codes
- DPF soot and ash load
- Differential pressure readings
- Exhaust gas temperature sensors
- DPF pressure sensors
- Boost pressure
- Airflow readings
- Injector balance (where applicable)
- Turbocharger operation
- EGR system operation
- Regeneration history
Many DPF problems are caused by an underlying fault rather than the filter itself. By identifying the root cause first, we can recommend the correct repair and help prevent the problem from returning.
HYDROSONIC DPF CLEANING
If your DPF is heavily restricted but still structurally sound, hydrosonic cleaning can often restore it to near-new condition.
Unlike chemical cleaners or forced regenerations, hydrosonic cleaning removes accumulated soot, ash and contaminants from deep within the filter using specialised cleaning equipment.
Benefits of hydrosonic cleaning include:
- Restores exhaust flow
- Improves engine performance
- Helps reduce fuel consumption
- Extends DPF life
- Removes ash that regeneration cannot burn away
- Cost-effective alternative to DPF replacement
- Environmentally responsible solution
After cleaning, the DPF is thoroughly inspected before being reinstalled and tested.
INTAKE MANIFOLD HYDROSONIC CLEANING
Modern diesel engines can also suffer from carbon build-up inside the intake manifold. Over time, soot from the EGR system combines with oil vapour from the crankcase ventilation system, restricting airflow into the engine. This build-up can contribute to:
- Reduced engine performance
- Poor throttle response
- Increased fuel consumption
- Rough idle
- Reduced airflow
- Loss of efficiency
Our hydrosonic cleaning process removes stubborn carbon deposits from the intake manifold, helping restore airflow and improve engine efficiency.
WHY WE CHOOSE HYDROSONIC DPF CLEANING
There are many DPF cleaning methods available, and not all are created equal.
One common method involves injecting a cleaning solution through the DPF sensor ports in an attempt to dissolve soot and contaminants without removing the filter from the vehicle. While this may provide a temporary improvement in some cases, it generally doesn't remove the ash and deposits that accumulate deep within the DPF over time.
At High Rollers 4x4, we prefer hydrosonic cleaning because it involves removing the DPF from the vehicle and cleaning it using specialised equipment designed to flush contaminants from throughout the entire filter. This process targets both soot and the ash that cannot be removed during a normal regeneration cycle.
By thoroughly cleaning the entire DPF rather than just treating it in place, hydrosonic cleaning offers a far more comprehensive solution and, in many cases, can restore a serviceable DPF to near-new performance without the cost of replacement.
Of course, if our diagnostics show that a DPF is physically damaged, melted or beyond repair, we'll explain your options and recommend the most appropriate course of action.
BOOK A DPF INSPECTION
If your diesel vehicle has entered limp mode, has a DPF warning light or isn't performing as it should, don't ignore the warning signs.
Our experienced technicians can accurately diagnose the problem, determine whether your DPF can be restored through hydrosonic cleaning, and recommend the most effective solution for your vehicle.
