❓ Frequently Asked Questions

► Why do Wheathampstead drivers see blocked GPFs more than expected?

Wheathampstead's country lanes and short journeys to St Albans, Harpenden or Welwyn Garden City involve a lot of low-speed, stop-start driving. A petrol GDI engine needs sustained high exhaust heat to burn off trapped soot, and these local routes rarely provide it.

► What does a blocked GPF mean for my Wheathampstead MOT?

A blocked or faulty GPF is an automatic MOT failure. A professional mobile clean typically costs £150–£350, far less than the £800–£2,500+ a dealer would charge for a full replacement.

► How long does a mobile GPF clean take for a Wheathampstead property?

Usually 60–90 minutes. We begin with an OBD diagnostic to confirm the fault, clean the filter on-site, then run a follow-up scan to make sure it's fully cleared.
