DPF Cleaning & Forced Regeneration

What the DPF does

The Diesel Particulate Filter traps soot to protect air quality. Short trips, failed regens or sensor issues can load the filter with soot and ash, causing high back-pressure, limp mode and turbo stress.

Our solutions

• DPF Clean (on-car): Professional cleaning to dissolve soot and lower back-pressure. From R1800.
• Forced Regeneration: We command a controlled regen to burn soot when conditions weren’t met during driving. With clean + regen: R2200.

Why not just “code it out”?

Removing DPF/EGR functions for road use can breach regulations, increase local pollution and risk test failures. We prefer to restore the system so it works as designed. If you’re building an off-road project, discuss your goals and local rules with us.

DPF vs performance over time

A healthy DPF has minimal impact on performance. A blocked DPF raises back-pressure, heats the turbo and hurts fuel economy — that’s why preventative maintenance is essential.

FAQs

Why did my DPF block?

Lots of short trips, stuck thermostats, EGR faults, weak glow plugs, old oil or a failing pressure/temperature sensor can all prevent regeneration.

Will cleaning fix it permanently?

Cleaning restores flow, but the cause must be addressed. We diagnose first, then clean, then confirm back-pressure readings.

Is forced regen safe?

Yes when monitored and the engine is healthy. We check oil level, temperatures and live data throughout.

What about ash?

Ash (from oil additives) can’t be burned off by regen. Our cleaning process targets soot; heavy ash loading may require off-car service or replacement.

How do I avoid repeat issues?

Fix underlying faults, use the correct oil, allow longer runs weekly, and consider an annual carbon clean to reduce soot formation.
