Expanded Answer (Simplified)
DPF replacement is one of the more expensive maintenance items for diesel vehicles, but costs vary significantly depending on your vehicle type and where you have the work done.
Typical Cost Ranges:
Small to Medium Cars: £1,500-2,500 total cost
- DPF filter: £800-1,500
- Labour: £300-500
- Additional parts: £100-200
Large Cars and SUVs: £2,000-3,000 total cost
- DPF filter: £1,200-2,000
- Labour: £400-600
- Additional parts: £150-250
Luxury Vehicles: £2,500-4,000+ total cost
- DPF filter: £1,500-2,500
- Labour: £500-800
- Premium parts and specialist labour
Commercial Vehicles: £2,500-4,000+ total cost
- DPF filter: £1,500-3,000
- Labour: £400-700
- Larger, more complex systems
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
