❓ Frequently Asked Questions

► Why is a blocked GPF such a common problem for Royston drivers?

Royston sits where the A10 and A505 meet, and most local trips towards Baldock, Letchworth or Buntingford are short and interrupted by junctions. That stop-start pattern stops the exhaust reaching the sustained heat a petrol GDI engine needs to clear the GPF on its own.

► Will my Royston car automatically fail its MOT with a blocked GPF?

Yes, a blocked or faulty GPF results in an automatic MOT failure. A mobile clean typically costs £150–£350, much cheaper than the £800–£2,500+ a full replacement filter can cost.

► How long does a GPF clean take for a Royston address?

Expect around 60–90 minutes. We run an OBD diagnostic first to confirm the GPF is actually blocked, carry out the clean on-site, then verify the result with a follow-up scan.
