Exhaust Clean Australia says it has the answer

Exhaust Clean Australia says it offers the ultimate emissions cleaning solutions for DPFs, SCRs, EGRs, intake manifolds, intercoolers and EGR coolers.
Most vehicles that frequent Exhaust Clean Australia are 4WDs and it reports that a lot of vehicle owners are not aware of how a DPF operates and what external factors influence how a DPF completes regenerations successfully.
Early intervention can save a fortune down the track in having to replace expensive components and large repair bills.
Exhaust Clean Australia notes that the majority of 4WDs these days require some degree of electronic reset once an oil and filter change are completed.
In the absence of completing the necessary resets electronically and with the overfilling of oil, Exhaust Clean Australia reports it has seen many a vehicle come to its team with owners in a frantic state thinking they’ve got a major DPF problem.
When it comes to diagnosing a DPF issue, Exhaust Clean Australia says checking for boost leaks is number one, and an easy process.
A scan tool won’t always tell you that the vehicle has a boost leak unless you are conversant with what faults codes may be apparent for the issue, but a simple visual check of hoses, looking for signs of oil vapour on hoses, clamps and intercoolers is a good place to start. However, some may be harder to find and might require smoke testing through to an in-depth diagnosis of boost levels and MAP sensor readings in live data on a road test.
Sensor failures is another staple cause of DPF issues. DPF pressure sensors, EGT sensors, MAF and MAP sensors right through to EGR sensors can all cause mayhem on the DPF and can easily be overlooked if the correct diagnostic process is not adhered to.
A blocked DPF can also be an early sign of a more sinister engine issue. Symptoms of badly worn or leaking injectors, excessive engine wear causing high crankcase and blow by issues can all make the DPF unhappy.
Exhaust Clean Australia says it has seen many vehicles where this scenario is commonplace and while some can be salvaged, others are destined for hefty engine rebuilding repair bills.
At the end of the day, Exhaust Clean Australia says you should not be too quick to hit the forced regeneration button on the scan tool and send the customer on their way.
Instead, it recommends the development of a diagnostic process which you stick to no matter what the vehicle exhibits problem-wise.
Finding the cause of the DPF issue and then rectifying the effect of a blocked DPF will make for many a happy customer who isn’t going to be back every month with a light back on the dash again, says Exhaust Clean Australia.
Exhaust Clean Australia offers a complete cleaning solution of emissions systems, new aftermarket units, and cleaned/tested second hand DPFs, as well as over the phone advice.
