Here we have a Mazda CX-7 with fault code P2459. The Mazda had low mileage and came into our Ashington HQ – Energy Tuning. The DPF light was illuminated and showed the fault code due to excessive failed DPF regenerations. The car was quickly back on the road after our 3 stage DPF cleaning service, which saved the customer around £2000 compared to the price of a new DPF.
