🔥 Why You Need DPF Regeneration
Regeneration (or \"regen\") is the process that burns soot accumulation inside your DPF filter. An unmaintained DPF filter:
- ❌ Runs your vehicle unnecessarily hard and less efficiently
- ❌ Reduces fuel mileage
- ❌ Makes your vehicle feel sluggish
- ❌ Can lead to engine derate and eventually engine shutdown
When Is DPF Regeneration Required?
- 🎨 The exhaust backpressure sensor is replaced
- 🎨 The PM trap is removed or replaced
- 🎨 The fuel additive nozzle is removed or replaced
- 🎨 The catalytic oxidizer is removed or replaced
- 🎨 The DPF regeneration MIL is turned on
- 🎨 The DPF regeneration control module is replaced
Why Perform DPF Regeneration Yourself with F804 Plus?
💰 Save BIG on Maintenance Costs
Dealer maintenance costs $500‑$2,000. Doing it yourself saves enough to buy a new vehicle!
⚡ Restore Full Power
Clogged DPF reduces power and mileage. Regular cleaning restores performance.
✅ Additional Benefits:
Better MPG · Better throttle response · Fewer regens · Longer DPF life · Less downtime
