Your home or your workplace is where the cleaning happens. A technician drives to you anywhere in Gwynedd and treats the DPF while the vehicle stays where it sits.

Nothing comes off the motor.

The starting figure is from £299. Attendance is often same-day or next-day and time on site is typically around 2 hours.

There are 361 towns and villages we reach across the county. Bangor, Caernarfon, West End, Bethesda and Upper Bangor are among them.

Every one of them is named further down this page, and each has a page of its own.

What the engineer does when they get to you

Nothing is treated until the scan is finished.

A DPF warning light is not proof that the filter is the fault, and a blocked filter commonly sits alongside a sensor, glow plug, injector or turbo fault that has to be ruled out first.

The cause turning out to be one of those is something you are warned of before work starts.

a full diagnostic scan and live read of the ECU, to establish the fault and see how full the filter is
chemical cleaner, under pressure and introduced through the easiest access point on that vehicle
a burn-off of what the clean loosened, run on a regeneration cycle
one brief road test where conditions allow, after a second scan and a warning lights reset
an email afterwards with the pre- and post-clean reports

Heavily blocked filters now and then need a second clean, carried out on the same visit.

How much is it in Gwynedd?

Nobody sets off before the price is agreed. Cleaning starts from £299; what you drive and how blocked the filter is both shift the figure from there.

A call-out charge applies to every visit.

Whether or not cleaning happens, the charge covers the call-out, the booking, the diagnostic and the advice that comes with it — a fault that is found to be something other than the filter is still a visit and still a diagnosis.

A 30-day warranty covers aftercare on every clean. Should the light come back inside it, a technician returns.
