Range Rover DPF Cleaning – Restoring Efficient Exhaust Flow
Initial pressure readings indicated 13 mbar and 1,100 hPa. The vehicle had covered 115,368 miles, making a thorough assessment of the DPF system an important part of the service.

Challenge:
The DPF pressure readings required attention to help maintain effective exhaust flow. With the vehicle's mileage in mind, the priority was to clean the filter and reduce the measured pressure levels.
Solution:
GMM1 carried out DPF cleaning, reducing the recorded pressure from 13 mbar to 6 mbar and the hPa reading from 1,100 to 700. These improved readings indicate reduced measured pressure after the service. This work supports more efficient exhaust flow and DPF operation.
