What’s Included in the Cost:
The DPF Filter Itself: This is the biggest expense, typically 60-70% of the total cost. Genuine manufacturer parts are more expensive but often come with better warranties.
Labour Costs: DPF replacement is labour-intensive, often requiring 3-6 hours of work depending on the vehicle.
Additional Components: Often need new gaskets, clamps, sensors, or other related parts.
Ways to Reduce Costs:
Aftermarket Parts: Can save 20-40% compared to genuine parts, but check warranty implications.
Independent Specialists: Often cheaper than main dealers while maintaining quality.
Remanufactured DPFs: Can save 30-50% but may have shorter warranties.
Professional Cleaning: Sometimes possible instead of replacement, costing £200-500.
When Replacement Might Be Covered:
Vehicle still under manufacturer warranty
Extended warranty coverage
Some insurance policies cover emission system failures
