❓ Frequently Asked Questions

► Why do Sherborne St John drivers get blocked GPFs?

Short, low-speed journeys around Sherborne St John — into Basingstoke or across to Old Basing — rarely let the engine run hot and hard enough for long 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.

► Will a blocked GPF cause an MOT failure?

Yes. An illuminated GPF warning light or engine management light is an automatic MOT failure. A professional GPF clean is typically £150–£350 — far cheaper than replacement at £800–£2,500+.

► How long does a mobile GPF clean take in Sherborne St John?

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.
