# AdBlue in a Diesel Tank in Periton? Don't Start It

Motor off, ignition off: that is how you start if AdBlue has got into the diesel tank.

Water with urea dissolved in it: that is AdBlue.

The harm begins once it is pulled through your pump — it will not burn, and it won't combine with diesel.

A drain and a thorough flush, done where the vehicle is in Periton, is usually what AdBlue in a diesel tank needs — if it's caught before your engine has been run.

Call 0333 366 0103 before you do anything else.

## AdBlue in your diesel tank in Periton: the first few minutes

Do these:

- So nobody can turn your ignition on, pull your keys out.

- Hazards on, if moving traffic is anywhere near.

- Keep the receipt or the empty bottle, so you can tell us what got in and about how much.

- Ring us from where you are. A postcode starting TA24 8, or the name of the nearest street, brings the van to you without a search.

Never:

- No starting your motor — not briefly, not to reposition your car.

- Many diesels run their fuel pump the instant your ignition comes on, so keep the vehicle off.

- Pouring in more diesel does not work: AdBlue settles out instead of thinning.

- Don't drive it anywhere, not even a short distance down South Park.

- Emptying your tank on your own beside the road isn't one to try.

Get the attendants to help you roll the vehicle away from the island if you are on a forecourt in Periton, whether it is the Texaco or elsewhere.

If you're on your own drive, leave it precisely where it stands.

## What does AdBlue do in a diesel tank?

Not your motor but the exhaust is where AdBlue is meant to go.

Its own reservoir holds it, and from there it's sprayed into your exhaust, and there it treats the gas.

A fuel pump isn't designed to cope with it, and AdBlue was never supposed to travel through one.

Tipped in with your diesel, it keeps separate instead of blending — entirely different from fuel.

It is heavier than diesel, and so it sinks and collects at the bottom of your tank, which is where the pickup draws fuel from.

A vehicle topped up on a driveway in Higher Town yesterday evening and left unstarted is the simple case. Nothing has sucked the AdBlue up yet — but once your engine runs, that is what goes first, directly from the bottom of your tank.

After it's pulled in, the harm takes two forms.

Crystals and corrosion. As the water dries, it leaves urea that crystallises in filters and narrow passages; meanwhile, because it eats at certain metals, each part it reaches keeps suffering for as long as it remains inside.

Lines holding AdBlue mean damage by morning for a car sitting around Periton. Just in that tank, it stays the same.

Diesel lubricates the high-pressure pump and each injector as it passes; water offers no lubrication, which is a separate kind of harm.

## Why AdBlue in a diesel is frequently more major than petrol

A fault of thin fuel is what you end up with from filling a diesel with petrol from the Morrisons.

Mixed into the diesel and left still, it's no threat for now; using your engine does the harm.

AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all.

Because it doesn't burn, running it through is not an option.

Nor can it be thinned, since it separates again — and the next fill will not clear away crystals or corrosion. So the flush matters more here, and turning the key "to see", in the centre of Periton or out in Alcombe, does more harm than almost any other slip.

The same good news applies as with petrol.

Never started? Then the AdBlue sits just inside that tank, the easiest section of the entire system to empty, wherever the car has stopped in Somerset.

## Periton: how AdBlue ends up in a diesel tank

After dark, two caps side by side — the AdBlue one and the diesel cap, occasionally under one flap — can appear the same. Nobody intends it; plenty of layouts allow it.

Usually it's never the forecourt: a driver picks up a bottle driving home and tips it in outside the house.

Usually, it occurs in one of a couple of familiar ways.

The refill gets rushed outside St Michael's Church of England First School, after your dash lit up with a warning as the kids were taken off.

In the evening, a container is tipped in on a driveway near Exmoor Way.

Or a driver unfamiliar with that flap tops up the vehicle after dark, stopped in the car park outside The Duke of Wellington.

The least familiar vehicles get it the most — rentals, new ones, fleet ones, and the spare car in a family with both fuels.

Wherever in Somerset, Periton included, the slip doesn't change, and neither does the first step: leave it off.

## Periton: started the motor with AdBlue in your diesel tank?

Then the AdBlue has left your tank.

With any running, it travels to the high-pressure pump and each injector, after passing through the filter and lines.

Watch for lumpy running, exhaust smoke, lost power, warnings on the dash, or a cut-out — coming back from Periton Park, say, or part way across Periton.

Stop as soon as it is safe, switch off, and don't restart the vehicle to check.

More of that is pulled through with each start.

Periton sits under 25 miles from the M5; if you were on it, exit at the next junction and pull up safely instead of carrying on.

Distance counts: each mile carries the AdBlue deeper into the system, so driving for Cardiff, under 25 miles away, gives a far larger job than crossing Periton to the car park by St Andrew.

Roughly how far had it come? Tell us.

Once your engine has run, the flush includes more, and all of it is done where the car has stopped.

Lasting damage is very unusual if it is caught quickly.

## What does an AdBlue drain on a diesel involve around Periton?

We come to the car, wherever it has stopped around Periton: a side street near Queen Anne, a drive, a lay-by or a forecourt.

The job depends on three replies, which our technicians get before all else — what got in, the quantity, and if the engine has run.

Next, draining your tank on the spot removes the polluted diesel and the AdBlue in one go.

A careful flush matters far more after AdBlue than with petrol, because residue won't clear out on its own.

Testing your vehicle follows last, once clean diesel is added and the fuel filter gets cleaned or, if necessary, replaced.

Most of these jobs are a half-hour visit once we get there, provided your motor has not run.

Quiet enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.

Lastly, the system is bled with clean diesel.

Then our technicians start it and you set off, whether from a parking space at the nearest station or a drive around Periton.

Before leaving, our technicians make sure it's running properly with clean diesel in.

No workshop is needed at any point, with the entire job done then and there.

Your insurer will want an engineer's report and the VAT invoice — both yours once this job is done.

## About Periton, for a moment

Periton is a suburban area in Somerset, situated near the coast and approximately 62 metres above sea level. Periton lies within commuting distance of several nearby towns, including Minehead and Bratton, and is also close to the Welsh border, with Cardiff being the nearest city. Periton has a population of around 2752 people, predominantly living in detached housing. Periton is part of the wider South West region, with London being around 147 miles to the east.

## Periton and Somerset: AdBlue drains across the area

The vans that answer AdBlue call-outs in Periton also cover the locations about it, Woodcombe, Minehead and Bratton among them, and most of Somerset beyond, across the TA postcode area.

If you're near a boundary, or somewhere hard to describe, ring and ask instead of assuming.

Periton is a residential suburb, and a call-out drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it sits, so it never needs to be shifted to us.

## What AdBlue in a diesel tank costs to put right in Periton

There's no fair single price, since the jobs aren't the same.

Whether the engine has been running, and for how long, comes first in what moves the cost. How much AdBlue got in comes next, and then the location of the vehicle, since an open drive is easier for a van to reach safely than a tight gap behind Rayners Gallery.

With that reason, each call from Periton opens with the identical trio — which fluid got in, how much, if the engine ran — ahead of any quote.

Those replies narrow a range right down to a single figure.

You hear that quote by phone, before anyone heads out, and you pay on the day, by card or over the phone, with nothing upfront.

While the van is on the way, dig out your policy: many cover misfuelling.

## Periton: still beside the car?

Then the most useful thing you can do is nothing to the car.

Ignition off, motor off, keys out.

Petrol in Diesel handles the rest, across Periton or wherever in Somerset, after you call 0333 366 0103 to say it was AdBlue, roughly how big an amount, and whether it ran.
