See an indicative UK DPF replacement cost and understand when cleaning, regeneration or diagnosis may be worth checking before fitting a new filter.
£595–£1,695
AutoAid reference: parts £400–£1,500, around 2.5 labour hours, using the current built-in UK labour reference of £78/hour.
This is a broad independent-garage sense-check, not a live quote. Vehicle specification, location, parts quality, corrosion and access can materially change the total.
A diesel particulate filter traps soot from the exhaust and periodically burns it off during regeneration. A blocked-DPF warning does not automatically mean the filter itself needs replacing, so diagnosis matters before committing to an expensive new unit.
A forced regeneration or specialist clean may be appropriate in some cases, but only after checking why the filter became overloaded. Faulty temperature or pressure sensors, EGR problems, injectors, boost faults and repeated short journeys can all contribute.
The filter price varies widely between vehicles and between aftermarket and manufacturer parts. Access, seized exhaust fasteners and whether sensors or clamps also need replacement can increase the labour and parts total.
Replacing a blocked filter without correcting the cause can lead to the new DPF becoming overloaded again. Fault-code data, pressure readings and the vehicle's regeneration history can help establish whether the problem is the filter itself or something upstream.
Put the quote into AutoAid and compare it with the relevant job benchmark and your regional labour rate.
