What does the p2459 code on DPF mean?
The P2459 code indicates that the regeneration process has not been completed with the desired frequency, over a programmed period of time (or amount of miles/km). This code should only be exhibited in diesel powered vehicles. DPF systems are designed to remove ninety-percent of carbon particles (soot) from diesel engine exhaust.
Why is my Mazda 6 DPF not working?
P2458 00-2F Diesel Particulate Filter Regeneration Duration (Meaning: The regeneration process is active for a too longer period, caused by only a small reduction in back pressure during the regen process). P2463 00-AF Diesel Particulate Filter – Soot Accumulation (Meaning: The DPF is blocked!)
What are the symptoms of DPF regeneration p2459?
Because DPF regeneration is critical to maintaining desired exhaust back pressure, addressing a P2459 should be considered a priority. Symptoms of a P2459 code may include: Excessive black smoke from the exhaust. Other DPF codes usually accompany the P2459. Inability to maintain RPMs.
Do you need DPF regeneration on a Mazda 3?
IF you are an owner of any Mazda Diesel (SKYACTIV) ( Mazda 3, Mazda 6, CX-3, CX-5, CX-8 ) from 2012 to present then you should be aware that DPF or DIESEL PARTICULATE FILTER Regeneration is Extremely important to maintain vehicle Emissions, Economy, Warning Lights, and yes Engine longevity.

When does DPF reset on a Mazda 3?
The pic below shows what can happen when the engine oil gets polluted with diesel when repeated DPF regen cycles have occurred over a long period of time. It can also happen if you use the wrong engine oil. Check and clean it every 80 – 100 thousand kilometers.
