Smart forfour DPF regeneration in Stoke‑on‑Trent
A diesel particulate filter that never gets a long enough run fills with soot, and the Smart forfour lights up its DPF warning or drops into limp mode. We hold 2 diesel forfour engines: pick yours below and we will clear the filter and fix what blocked it.
A DPF regeneration on a diesel Smart forfour burns the soot out of the filter, and we fix what stopped it clearing itself, at our unit in Fenton, Stoke-on-Trent. It is priced on request. We hold 2 diesel forfour engines: pick yours below, then message us with your reg.

Message us about this engineWhat a DPF regeneration is
Every diesel forfour has a diesel particulate filter that traps soot and burns it off on longer runs. Short journeys stop that happening, the filter fills, and the car shows a DPF light or drops into limp mode. A forced regeneration burns the soot out in the workshop and the filter stays on the car.
Why forfour owners ask for it
- Clears a blocked filter without the cost of a new one
- Gets the car out of limp mode and back to full power
- The filter stays in place, so nothing changes for the MOT
How it works
Diagnose
We read the fault codes, the soot load and the differential pressure, and look for the cause: a faulty sensor, an EGR fault or a run of short journeys.
Fix the cause
Anything that stopped the filter regenerating on its own is dealt with first, or it will block again.
Forced regeneration
We run a forced regeneration with dealer-level diagnostics, burning the soot out of the filter under control.
Check and hand back
We check the soot load and pressure readings again and clear the codes before the car goes back to you.
Pair it with a remap
A clear filter is the right time for a Stage 1 remap too. The 1.5 Diesel 95hp typically goes from 94bhp to around 120 to 125bhp at Stage 1, from £249.
