Renault Megane – On-Site DPF Cleaning to Restore Performance

A Renault Megane (LV66 KTK) was attended at SG13 8LU, 1 Little Berkhamsted Lane, after symptoms pointed towards a heavily restricted DPF. Initial diagnostics showed a high pressure reading of 57.3 mbar, indicating poor exhaust flow. Our on-site DPF cleaning service was carried out, reducing the pressure to 22.8 mbar and restoring proper system efficiency at 93,248 miles.

Service: DPF Cleaning
Date: 26-Dec-2025
Make: RENAULT
Model: Megane
Area: London
Challenge:
With the vehicle having covered 93,248 miles, soot accumulation within the Diesel Particulate Filter had reached a level that restricted exhaust flow. Diagnostic checks confirmed elevated DPF pressure at 57.3 mbar, a clear sign that the filter was struggling to regenerate effectively. Left untreated, this level of blockage can quickly lead to warning lights, power loss, and further exhaust-related faults.
Solution:
Our technician provided a mobile DPF cleaning service at the customer’s address, using specialist equipment designed to safely remove built-up soot from the filter without dismantling. Following the cleaning process, the DPF pressure dropped to 22.8 mbar, confirming a significant improvement in airflow. The Renault Megane was left running smoothly, with the DPF system operating within healthy limits once again.
