What a DPF regeneration is

Every diesel GLS 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 GLS 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

  1. 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.

  2. Fix the cause

    Anything that stopped the filter regenerating on its own is dealt with first, or it will block again.

  3. Forced regeneration

    We run a forced regeneration with dealer-level diagnostics, burning the soot out of the filter under control.

  4. 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 4.0 Diesel 612hp typically goes from 604bhp to around 655 to 695bhp at Stage 1, from £249.
