❓ Frequently Asked Questions

► Why do Berkhamsted cars seem particularly prone to GPF blockages?

Berkhamsted's narrow High Street (the A4251) and the surrounding lanes towards Tring and Hemel Hempstead mean a lot of driving happens at low, constant-braking speeds. Petrol GDI engines need sustained high exhaust heat to clear soot from the GPF, and that heat is hard to reach on these routes.

► Will a blocked GPF actually fail my Berkhamsted MOT?

Yes — a blocked or damaged GPF is an automatic MOT failure. A mobile clean generally costs £150–£350, considerably less than the £800–£2,500+ a dealer typically charges to replace the filter outright.

► How long will a mobile clean take at my Berkhamsted address?

We start with an OBD diagnostic check to confirm the blockage, then clean the filter on-site — the whole visit usually takes 60–90 minutes. A final scan afterwards confirms the GPF is reading clear.
