# Swynnerton: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has got into the diesel tank, leave your engine off and leave the ignition off.

Water with urea dissolved in it: that's AdBlue.

Unlike fuel, it neither burns nor blends, and nothing happens until your engine sucks it round.

In Swynnerton, AdBlue in a diesel tank caught before your engine runs usually means a drain and a thorough flush, just where your car is.

Before you do anything else, phone 0333 366 0103.

## AdBlue in the diesel tank in Swynnerton: the first few minutes

Things to do:

- Keys out — then nobody can switch anything on.

- Put the hazard lights on if you're at all near moving traffic.

- Which fluid, and roughly what quantity? Save the bottle or the till receipt, and we can know.

- Call us from where you are. A postcode starting ST15 0, or the name of the closest street, brings our van to you without a search.

Do not:

- Moving your vehicle even a short way is no reason to start your motor.

- Many diesels power their fuel pump the instant the ignition comes on, and so keep it off.

- No more fuel on top. The AdBlue will not mix, and so it's wasted.

- Leave the vehicle where it is rather than driving it anywhere, even a short distance along Stab Lane.

- No emptying it yourself, at all, on the roadside.

Moving your car off the island is a job for attendants to help with, whichever Swynnerton forecourt you are on, the BP or any other.

If you are on your own drive, leave it precisely where it sits.

## What AdBlue does in a diesel tank

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

Its own reservoir keeps it, and from there it is fed into the exhaust, where it treats the gas.

No part inside an injection pump is made for this liquid — and none of that was intended to go through one.

Poured in with your diesel, it stays apart rather than mixing — entirely different from fuel.

The intake sucks fuel from the lowest part of that tank, and that's just where AdBlue ends up: being heavier than diesel, it sinks.

A vehicle topped up on a driveway in Cotes Heath overnight and left unstarted is the straightforward case. No pump has pulled the AdBlue up so far — though when your engine turns, that is what is pulled first, directly from the bottom of your tank.

From there it does two kinds of damage.

It attacks some metals used in fuel components, attacking any part it reaches until it is removed from your system. And once the water goes, the urea turns into crystals that clog filters and lodge in tiny channels.

If the AdBlue is in the pipework, waiting overnight around Swynnerton makes it worse. Inside that tank only, time costs nothing.

Water lubricates nothing. The high-pressure pump and each injector depend on diesel running past them, and so the water part damages them by itself.

## AdBlue in a diesel: why it's commonly worse than petrol

Put petrol in a diesel at the Morrisons and you have an issue of thin fuel.

Blended through the diesel and left still, it is no threat at that stage; using the engine is the harm.

AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all.

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

Whether your vehicle sits in Cranberry or the centre of Swynnerton, turning it over "to see" does more harm with AdBlue than almost any other slip, and the flush matters for more. Why: it won't remain mixed, so diluting it is impossible; and crystals and corrosion survive the next fill.

With AdBlue, the good news is no different from petrol.

If the motor hasn't run, the AdBlue is still in your tank, and the tank is the simplest part of a fuel system to clear, wherever in Staffordshire your car is standing.

## How does AdBlue end up in a diesel tank in Swynnerton?

After dark, two caps together — the AdBlue one and the diesel one, now and then behind a single flap — can appear the same. No one intends it; many layouts invite it.

Mostly it occurs with a bottle bought on the way home and poured in on the drive, not at the forecourt.

Mostly, it occurs in one of a few familiar ways.

Midway through the drop-off, the dashboard warns, and outside All Saints CofE (C) First School the top-up is hurried.

In the evening, a bottle goes in on a driveway close to Tittensor Road.

Otherwise, after dark outside Fitzherbert Arms, your vehicle is refilled by a driver opening that flap for the first time.

The least known cars get it most — hire cars, brand-new ones, company cars, and the other vehicle in a family with one of each fuels.

Leave it off: that is the first step to an identical mistake, wherever in Swynnerton or the remainder of Staffordshire you happen to be.

## Already started the motor with AdBlue in your diesel tank around Swynnerton?

In that case, the AdBlue is no longer inside your tank.

Given any running, it travels to the high-pressure pump and every injector, having passed via the fuel filter and lines.

You may see the motor running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Stabhill Plantation or halfway across Swynnerton.

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

Each start pulls more of that through.

Exit the M6, under a mile from Swynnerton, at the first junction and park safely, not carrying on.

A quick hop across Swynnerton to the car park by Swynnerton Village Hall is one matter; driving towards Stoke-on-Trent, under 10 miles away, is something else, since every mile pushes the AdBlue deeper in. So distance matters.

Roughly how far had it come? Tell us.

Wherever your car came to a stop is where all of it gets done, even with more to rinse out once the motor has been running.

Lasting damage is very uncommon if it is caught early.

## Swynnerton: how AdBlue is emptied from a diesel

The car remains where it is, whether that is a street near St Mary, a drive, a layby or a forecourt around Swynnerton, and our van travels to it.

Three replies decide the work, and so before anything else our engineers ask what went in, about the amount, and whether the engine has run.

Right there, the tank is then drained, and all of the polluted diesel and the urea leave at once.

With AdBlue, more so than with petrol, the flush counts: the whole system is flushed right through because residue won't flush out by itself.

A test of the car follows last, after fresh diesel is added and your filter is cleaned or, where necessary, swapped.

The majority of these jobs are a half-hour job once our engineers get there, if the engine hasn't run.

The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house at night.

The final step is to bleed the system on clean diesel.

Starting the engine comes next, and then you drive off from where the vehicle is parked, at Barlaston or on a driveway around Swynnerton.

The test before our engineers head off is that it runs smoothly on clean diesel.

Since the job is done in its entirety where your car is, a workshop never comes into it.

Insurers want a VAT invoice and an engineer report, and both come at the end.

## AdBlue drains around Swynnerton and across Staffordshire

Our teams that answer AdBlue jobs in Swynnerton also cover the places around it, Sandyford, Cotes and Beech among them, and most of Staffordshire beyond, across the ST postcode area.

Guessing doesn't help by a county line or somewhere hard to pin down; phone and check.

Anywhere your car stands — your driveway at home, a residential street, a parking area, a filling station — our technicians drain it there, and there's no need to take it to us; that suits Swynnerton, a rural village, well.

## What does AdBlue in a diesel tank cost to sort out around Swynnerton?

Each job is different, and so not one fixed price would be honest.

What moves the cost is, first, whether your engine has run and for how long; then how much AdBlue got in; and then where your car is and whether a van can reach it safely, which is easier on an open driveway than in a tight gap behind Our Lady of the Assumption.

Which fluid went in, how much, and whether the engine ran: each Swynnerton call begins with exactly those, before a quote, not afterwards.

Given those replies, the range narrows to a single fixed figure.

Our quote is given on the call, before a van leaves; settling up happens on the day, by card or over the phone, with nothing upfront.

Look at your policy whilst we're on the way: plenty include misfuelling cover.

## Swynnerton: still beside the car?

Then, the best thing to do with your vehicle is to leave it.

Motor off, keys out, ignition off.

Tell us it's AdBlue, roughly what quantity, and if the engine ran, on 0333 366 0103. After that Petrol in Diesel handles it, in Swynnerton or anywhere in Staffordshire.
