Mobile DPF Cleaning covering Rotherwick, Hampshire

The cause diesel particulate filters clog round Rotherwick

For a DPF, the poorest driving is the sort you meet around a rural village such as Rotherwick. None of it goes on long enough or runs hot enough for the filter to complete a regeneration: the school run to Whitewater Church of England Primary School, Post Horn Lane standing at half past eight, five minutes to Sainsbury's, the run to Hook. Instead of burning off, the soot load builds up.

Neither is distant from Rotherwick: under 3 miles to the M3, under 25 miles to Winchester. Neither is on the way to anywhere most weeks, though, so the drive that would empty a filter never gets made.

The motor stays put for on-site DPF cleaning across Rotherwick

Nothing is taken from the car. That surprises people. The DPF sits fixed where it is and the work happens around it, on a driveway, in a works car park, wherever it can wait for a few hours.

First a check. Running ECU data, the soot load as a percentage and as a weight, the sensor readings, the glow plugs, the associated components — all of it logged before anything is started.

Soot and ash that a regeneration by itself will never move are loosened next, by a solution put through the entry point on that car, which spreads inside the filter. Where the filter is heavily clogged, expect a second pass.

Then a regeneration, to drive off what the clean has lifted. Either it is done as a monitored drive out of Rotherwick, with you along, or it runs where the vehicle stands and the live data is checked afterwards.

A second check confirms the change, clears the warning light and logs anything still outstanding. Both reports are emailed, so you keep the before and after figures recorded.

Figures for DPF cleaning around Rotherwick

A call-out charge applies whatever happens, and takes in the visit, the booking fee, the diagnostic and the advice passed on. Treatment itself begins from £299.

Once we have what you drive, and about what the filter will take, the price gets fixed over phone. A single price for all would not be truthful. Two things move it: what you run, and where you are — Rotherwick itself, across at Hartley Wespall, or further out in the RG postcode area.

If the diagnostic rules a clean out, there is nothing to pay for it. What even so stands is the call-out charge, since the visit was made, the scan was carried out and the advice was offered.

Aftercare is taken in by a 30-day warranty: should the light reappear within it, an engineer comes back to Rotherwick.

Questions Rotherwick drivers ask about DPF cleaning

Will a long drive shift it?

Sometimes, if you get it early enough and the car has not slipped into limp mode. That means motorway speed for a steady run, rather than a quick trip to Sainsbury's.

How long does the visit take?

It is typically around 2 hours. A severely clogged filter can need a second clean, which lengthens that.

The cost in Rotherwick — what is it?

The call-out charge covers the visit, the scan and the advice; the clean itself starts from £299. The vehicle and your address both shift the price, so we quote on the phone.

Must I be there in person?

The vehicle wants a spot for two hours or so. Nobody expects you to be in it. If you would sooner come along, the regeneration can be run as a watched drive instead.

When can someone come to Rotherwick?

You are looking at often same-day or next-day, though it depends what is currently in the diary. Call 0303 330 1830 and you will learn what is available across the RG area.

The filter — does it leave the motor?

Not on the on-site service — it is treated where it is. We never lift filters off or bolt them back on, whichever way.

What if the light returns?

Included by the 30-day warranty: aftercare, and an engineer travelling back to Rotherwick.
