❓ Frequently Asked Questions

► Why do so many petrol cars in St Albans develop a blocked GPF?

St Albans city traffic, especially around the A414 ring road, involves constant braking and low average speeds. Short trips out to Harpenden, Hatfield or Watford rarely give a petrol GDI engine the sustained heat it needs to burn soot out of the GPF naturally.

► Does a blocked GPF cause an automatic MOT fail in St Albans?

Yes — a blocked or faulty GPF is an automatic MOT failure. A mobile clean costs around £150–£350, versus £800–£2,500+ for a full dealer replacement, so it's worth checking before your test.

► How long will a mobile GPF clean take at my St Albans home?

Typically 60–90 minutes from start to finish. We first run an OBD diagnostic to confirm the blockage, clean the filter on-site, then verify the result with a follow-up scan.
