Short trips between Stevenage's town centre and neighbouring Hitchin, Knebworth and Letchworth rarely sustain motorway-level revs, preventing petrol GDI engines from reaching the 600°C+ needed for passive GPF regeneration.

❓ Frequently Asked Questions

► Why do Stevenage drivers report blocked GPFs so often?

Stevenage's town-centre roundabouts and short hops to Hitchin, Knebworth or Letchworth keep most journeys at low, variable speeds. Petrol GDI engines need sustained high exhaust heat to burn off trapped soot, which this kind of driving rarely provides.

► What happens at my Stevenage MOT if the GPF is blocked?

A blocked or faulty GPF triggers an automatic MOT failure. A professional mobile clean is typically £150–£350, well below the £800–£2,500+ cost of a full replacement filter.

► How long does the mobile GPF clean take in Stevenage?

Usually 60–90 minutes per visit. Our technician runs an OBD diagnostic first to confirm the blockage, performs the clean on-site, and verifies the fix with a follow-up scan.
