❓ Frequently Asked Questions

► Why do Hatfield drivers get blocked GPFs?
Short urban journeys are the norm for drivers moving between Hatfield, Welwyn Garden City and St Albans. These stop-start conditions prevent petrol GDI engines from reaching the sustained exhaust temperatures needed for the GPF to burn off trapped soot, so deposits build up over months until the filter restricts flow.
► Will a blocked GPF cause an MOT failure?
Yes — a lit GPF or emissions warning light is an automatic MOT failure. A professional clean typically costs £150–£350, well below the £800–£2,500+ needed for a replacement filter.
► How long will my Hatfield GPF clean take?
Most GPF cleans take 60–90 minutes on-site. We carry out a full OBD diagnostic first, clean the filter, then verify the result before we leave.
