Signs Your DPF Needs Attention
- DPF warning lamp illuminated
- Increased fuel consumption
- Reduced engine power (limp mode)
- Failed active regeneration cycles
- Backpressure reading above 2.5 kPa at idle
The Case for Cleaning
Professional DPF cleaning — pneumatic pulse cleaning followed by thermal bake-out — can restore a partially clogged filter to near-new efficiency at a fraction of replacement cost. Our sister company, Len's Clean Air Inc., specializes in this service across Canada. Cleaning is cost-effective when the substrate is structurally intact and ash loading is below 70%.
The Case for Replacement
Replace when: the substrate shows visible cracks or melt zones, repeated cleanings have not resolved the issue, the filter is original and past 600,000 km, or the cost of downtime for another cleaning cycle exceeds the value of replacement. At those points, a quality aftermarket DPF from DPF Global is the smarter investment.
