The engineer pulls up with the kit in the van and sets to work where the motor is. The DPF stays fitted, it's cleaned then regenerated on the vehicle, and once the job's finished your vehicle is ready to use. Two hours or thereabouts does for the whole thing, at prices from £299, fixed over the phone first. ## What a mobile DPF regeneration visit around St Thomas entails Somewhere for the van to sit, plus an engine that will run at intervals, is the whole requirement. After that, it runs the same four steps each time: - A percentage and a soot weight come off the engine ECU first, plus a check the connected hardware, sensor feeds and plugs, ahead of anything being touched. - Ash and soot a regeneration would never move are what this step breaks up, using a cleaning solution introduced at that motor's injection point and left to expand inside the DPF. - A DPF regeneration then clears what the clean has freed, either where it is where the vehicle is parked or on a monitored run out of St Thomas if you would like to come along. - Any stored codes still showing get written down at that stage, once the difference has been confirmed and the dash light put out. Emailed over once the second scan is complete, both sets of numbers go on file. ## Where does on-site DPF cleaning take place around St Thomas? Anywhere the motor can stand for the couple of hours. Which normally comes down to one of these: - A driveway at home across in St Thomas - The car park at your workplace - The spare end of a yard - Off Edina Mews, in a yard - The Co-op Food customer car park, while you do something else No standing around with the car, and no DPF being taken from it while you are gone. ## The reason diesel particulate filters clog round St Thomas If you travel in and out of St Thomas, a residential suburb, you're giving the filter exactly the runs it manages worst. The school run to Bowhill Primary School, the crawl along Cowick Street at the morning rush, five minutes to Co-op Food and back, the dash to Exeter St Thomas — none of it goes on long enough or gets hot enough for the filter to finish a regeneration cycle, so soot that should burn away collects instead. Geography adds to it. The M5 is under 3 miles from St Thomas and Exeter sits under a mile away, so unless you have a regular reason to make that journey, whole weeks pass without the sustained drive that would empty the filter on its own. By the time the light comes on, the symptoms have usually been building a while: pull dropping away, revs that will not climb the way they should, a diesel smell in the interior or dark smoke under acceleration, worse fuel economy, and auto stop-start giving up silently. ## What mobile DPF cleaning answers, and what it does not A choked filter is what treatment answers. It is not the fix to everything that puts the very same light on a dashboard, and the diagnostic is what tells the two apart prior to anything being cleaned. Cleaning will not cure: - A pressure or temperature sensor reporting a blockage that is not genuine - An EGR valve held open - A failure with the urea system - Plugs or injectors blocking a regeneration from starting at all - Turbo problems putting oil into the unit Where the fault lies in one of those, we say so ahead of any job getting going rather than after you have settled up for it. Driving without a serviceable DPF is illegal and the vehicle will not clear an MOT, so having the DPF hollowed out solves nothing. Nor is anything exchanged: what people look up as DPF renewal is the same DPF, treated where it sits and returned to service. ## Attempt a long drive before calling Where a filter has only begun to fill, a long run frequently clears it with nobody touching it. under 3 miles sits between St Thomas and the M5, and that is the drive to make, holding the pace steady. The longer route into Exeter serves too. Five minutes to Nadderwater and home does not. Once the light is on and the motor has fallen into reduced power, that window has gone and a mobile job is the obvious next step. ## What mobile DPF cleaning comes to across St Thomas Prices for on-site DPF regeneration begin from £299. Driving to you, taking the booking, carrying out the diagnostic and handing you the steer are all paid for by the call-out fee, which applies whatever the outcome. You'll be given the number over the phone rather than from a list, because the vehicle and the state of the DPF both change it. Let us know what you run and roughly where you are — St Thomas itself, over by Exeter, or elsewhere in the EX postcode area — and you will know the price before a soul is sent. A 30-day warranty sits behind the work, aftercare included. If that light's back inside the window, you'll see a technician out to St Thomas again. ## Vehicles we clean DPFs on around St Thomas The same on-site visit covers: - Your car - Light commercials - HGVs and heavy goods vehicles - Plant and site machinery - Agricultural plant You're not bringing anything to us: on each one the DPF is cleaned in place, at your door in St Thomas. If the vehicle will not turn over at all, the mobile service cannot reach it: the DPF comes off by you or your garage, goes to our premises by carrier, and is cleaned within a day of reaching us. We do not take off or refit units for either service. ## The EX area and St Thomas: where we work There's usually a van on Cowick Street most weeks, so St Thomas is rarely out of the way. The same route covers Exeter and Ide, and the villages over past Nadderwater and Shillingford Abbot. Being further out across Devon is no obstacle. Coverage extends UK-wide; what decides whether it is today or tomorrow is the local schedule rather than the journey. ## Mobile DPF cleaning questions from around St Thomas How long is the visit?
