❓ Frequently Asked Questions

► Why are GPFs so often blocked in Letchworth Garden City?

With most local trips staying under a few miles between Letchworth Garden City and neighbouring Baldock or Hitchin, exhaust temperatures rarely climb high enough. 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.

► Can a blocked GPF stop my car passing its MOT?

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 Letchworth Garden City 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.
