How much does a DPF clean cost?

Forced regen on a scan tool: £60–£120. Off-car professional clean: £250–£450. Replacement: £900–£2,500.

Here's a quick, honest answer from a working UK mechanic — what causes it, what it costs to fix, and what to do next.

Why does my DPF keep blocking? — Short journeys, faulty differential pressure sensor, or wrong engine oil are the main causes.

Can I drive with a blocked DPF? — Only briefly. Sustained driving with a blocked DPF damages the turbo and engine.
