❓ Frequently Asked Questions

► Why do so many cars in Ambrosden end up with a blocked GPF?

Ambrosden sits amid a cluster of villages around Bicester, so many local cars only ever do short, low-speed trips to the shops, school or the station. A petrol GDI engine needs sustained running at motorway speed and load for the exhaust to reach the 600°C+ required for passive GPF regeneration, and journeys around Ambrosden rarely get hot enough or long enough for that to happen, so soot gradually builds up and blocks the filter.

► What happens at MOT time if my GPF is blocked?

A blocked or missing GPF is an automatic MOT failure under the current emissions rules, regardless of how the car otherwise drives. Getting ahead of it with a professional clean typically costs between £150 and £350, whereas leaving it until the filter is damaged or fully clogged can mean a replacement bill of £800 to £2,500 or more, so it is far cheaper to deal with early.

► How long does a mobile GPF clean take when you come to Ambrosden?

We start with an OBD diagnostic check to confirm the GPF is genuinely the problem and to record baseline fault codes and soot load, then carry out the clean itself, which takes around 60 to 90 minutes in total on your driveway or at your workplace. Afterwards we re-run the diagnostics to verify the filter is clear and clear any stored fault codes before we leave.
