The Check Regen Lights Came on Again
Your DPF warning light simply came on: What should you do?
It'southward unsettling, but if your diesel fuel particulate filter alert lite comes on here'south what you do…

When your DPF warning light comes on, recollect this: Orangish warning lights are sub-critical events.
You demand to act, but it's not life and death for your engine.
Red warning lights, on the other paw, are reserved for engine life and expiry.
So, vehicles are subtly different, and the DPF light activation scheme varies. Consult the owner'southward transmission, and practice what information technology says.
A flashing orange DPF light (or whatever the chief activation mode is) just tells y'all that the filter is getting loaded upward, and a burn down or regeneration is necessary and/or overdue.
The car knows this because it measures the force per unit area drop beyond the DPF. More pressure drop equals more than clogging equals demand to regenerate now. Regeneration is usually seamless and automatic, in the groundwork, but for some reason this has fallen over on your vehicle.
And then as soon as you tin can, get out on the highway and become for a complimentary-flowing cruise. Get in a priority because not addressing this will get expensive. Aim for about an 60 minutes of cruising - l kays one mode, and return (ish). And then, 100 all up.
Don't shift to second and rev the crap out of the engine on some tranquility suburban street, or try whatever other cockamaime hack to regenerate - specific conditions need to be met earlier a filter regenerates.
Highway cruising is the easiest way to meet those weather condition. If the light goes out, it worked. Excellent. If not, you need to visit a workshop. It can exist a dealership or an independent workshop, just if it's an contained make sure they're familiar with this trouble.
They can plug in to the diagnostic port and force the vehicle to do an ambitious regen in the service bay. And that might turn the car'due south DPF frown upside-downwardly. If that doesn't work, y'all tin await at getting the DPF cleaned. They can inject special solvent and endeavour breaking up the blockage. It's worth a shot - because this is much cheaper than a replacement DPF.
If that doesn't work and you're up for a new DPF, the cost of the genuine unit of measurement from the authorised dealer might just about give you middle failure. They exercise typically charge an arm and a leg for these things.
Before agreeing to the toll, investigate aftermarket solutions. Equally DPFs proliferate on our roads, the economies of calibration producing good quality aftermarket units continue improving. This could save yous a few hundred to a few chiliad dollars, depending on the vehicle.
PRO TIPS for DPFs:
-
Prioritise your DPF gets adequate routine highway driving to permit regenerative procedure to happen
-
Use a qualified technician knows what they're doing to service your DPF: Don't be scared to ask.
-
Ensure the right low-ash oil has been used during servicing: Once more, inquire, write information technology downwardly.
-
Confirm appropriate computer settings have been reset: Eg. oil dilution reset
-
DPF issues are symptoms (typically) of the core problem: Eg. Warning light = blockage. Blockage = inadequate highway driving.
-
Remember: Possessor abuse is how manufacturers escape warranty claims - DPF abuse is very much function of that. If y'all accept a serious DPF failure and they can argue the example for inadequate driving conditions, you could be forced to pay for your repairs.
Cause and effect
A couple of other things to realise.
Nearly DPF problems are caused by a failure to practise adequate highway driving. If you have a DPF-equipped vehicle, attempt to leave on the open road once a fortnight for about an hour, minimum.
The other matter to remember is that DPF faults are oft symptoms, rather than the core problem itself.
DPF warning lights herald a blockage, simply the blockage can be a symptom that (perhaps) yous're not doing enough highway driving. Merely information technology tin can also be symptomatic of a more malicious (and harder to diagnose) problem.
For example, if at that place's an air leak in the inlet, later on the turbo and the MAF sensor, then the MAF sensor volition read besides loftier (relative to the air that'southward actually making it into the engine). The car is then going to over-fuel continuously.
When that happens, particle production goes through the roof, and the filter keeps clogging. The symptom is the clogging. The disease is the crack in the inlet air plumbing. If you don't cure the disease, the symptoms volition just keep popping up.
And then what I'm saying here is y'all often need a really skillful mechanic with high-level fault finding skills to go to the bottom of this. Dealerships don't often have these skills, and it'south easy to go trapped into this 'Groundhog Twenty-four hours' / DPF death / hell on world feel where you pay the big bucks, replace the DPF, and so it merely dies again, repeat.
If that happens, this is the massive wake-upward call that the repairer is treating the symptom and not the illness.
So if your DPF warning light, lights upwards, don't panic. It's not an emergency. But don't ignore it either - because it's not going away unless you human activity.
And if y'all do ignore it, the problem'due south just gunna get worse. Meaning 'much more expensive'.
