Professional DPF Cleaning Completed for a Porsche Cayenne in Harrow
Initial diagnostic testing identified an excessive DPF pressure reading of 47 mbar, indicating a significant restriction within the diesel particulate filter. Following our professional cleaning process, the pressure reduced to 37 mbar, demonstrating a noticeable improvement in exhaust gas flow. The vehicle's recorded mileage at the time of service was 68,761 miles.
DPF pressure readings recorded before the cleaning service, showing an initial differential pressure of 47 mbar during diagnostic testing on the Porsche Cayenne.

Challenge:
The diesel particulate filter had accumulated soot deposits, resulting in higher-than-normal back pressure. If left unresolved, this could have led to reduced engine efficiency, increased fuel consumption, and potential DPF-related warning lights.
Solution:
Our mobile technician performed a professional on-site DPF cleaning, significantly reducing the filter restriction and improving exhaust flow. The vehicle was returned with healthier DPF readings, helping to enhance engine performance while reducing the likelihood of expensive future DPF repairs.
