Mercedes GLA On Site DPF Cleaning for Performance Restoration

A 2015 Mercedes GLA dropped in limp mode after its DPF became severely blocked, showing a high differential pressure of 58.5 mbar. Our technician carried out a full on-site DPF clean using specialist equipment, bringing the pressure down to 9.4 mbar. With the soot load safely removed and the system flowing freely, the vehicle’s performance was fully restored and the DPF warning light disappeared immediately.

Challenge:
The customer reported sudden loss of power, and diagnostics confirmed the vehicle had gone into limp mode due to an overloaded DPF. The filter was holding excessive soot and ash, preventing natural regeneration and triggering high pressure readings. At 58.5 mbar, the system was too restricted for normal operation, leaving the Mercedes unable to deliver proper boost or throttle response.
Solution:
Our mobile technician performed a complete on-site DPF cleaning service, using advanced flow-restoration equipment to break down and flush the built-up deposits inside the filter. After the cleaning cycle, the differential pressure dropped to 9.4 mbar, confirming that the DPF was functioning properly again. A final scan showed no DPF light on the dashboard, and the Mercedes GLA regained smooth, unrestricted performance right on the spot.
