# AdBlue in the Diesel Tank in Braunstone Town? Keep It Switched Off

With AdBlue in the diesel tank, the ignition stays off and so does the motor.

AdBlue is urea mixed in water.

The harm begins once it is pulled through the pump — it will not ignite, and it will not combine with diesel.

If the motor has not run yet, AdBlue in a diesel tank is normally drained and carefully flushed where your car sits around Braunstone Town.

First, ring us on 0333 366 0103.

## Braunstone Town, AdBlue in the diesel tank: what to do at once

Do:

- Take your keys out, so no one switches the ignition on.

- Hazards on, if moving traffic is anywhere close.

- Hold on to the till receipt or the empty bottle, so you can tell us what was put in and roughly how much.

- Give us a postcode starting LE3 3, or whatever street is closest, and our van finds you directly — so call from wherever you are.

Things not to do:

- Do not start the engine, even for a moment to shift your car.

- Don't switch the ignition on. On plenty of diesels that alone runs the fuel pump.

- Pouring in more diesel doesn't help: AdBlue separates out rather than blending.

- Leave the car where it is instead of driving it anywhere, even a short way along Balmoral Drive.

- Draining your tank yourself by the road isn't worth trying.

The attendants on duty at any Braunstone Town forecourt — the Esso among them — will normally lend a hand rolling it clear if you ask.

On the drive, the car remains exactly as it was left.

## AdBlue in a diesel tank, and what it does there

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

It goes into its own tank and is sprayed into the exhaust gas to fresh it.

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

Inside a diesel tank it acts really differently from fuel. It does not mix in.

The pickup sucks fuel from the lowest part of your tank, and that's precisely where AdBlue settles: being heavier than diesel, it sinks.

Simplest of all: a vehicle that had AdBlue in Western Park overnight and hasn't turned since. The AdBlue waits at the foot of the tank, untouched — but it would be the first thing through if the engine runs, ahead of any diesel at all.

After it is sucked in, the harm takes two forms.

Crystals and corrosion. As the water dries, it strands urea that crystallises in filters and tiny passages; meanwhile, since it eats at certain metals, every part it reaches keeps suffering for as long as it stays in there.

A vehicle left standing in Braunstone Town with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't.

The water in it causes harm of its own: the high-pressure pump and the injectors depend on diesel to lubricate them, and water gives them nothing.

## Why AdBlue in a diesel is commonly more significant than petrol

Top up a diesel with petrol in error at the Shell, and the problem is thinned fuel.

Mixed through your diesel and sitting still, it is no threat for now; running your engine is the damage.

AdBlue in a diesel is an issue of the wrong substance altogether.

Not burning, it cannot simply be run through.

It does not stay mixed, so it can't be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than almost anywhere else, whether the car is in Fosse Park or the middle of Braunstone Town.

The same good news holds as with petrol.

Not started? Then the AdBlue sits just in your tank, the simplest section of the whole system to clear, anywhere your vehicle has come to rest around Leicestershire.

## AdBlue in a diesel tank around Braunstone Town: how it ends up there

In dim light, two caps side by side — the AdBlue cap and the diesel cap, occasionally under a single flap — may appear the same. No one intends it; plenty of designs allow it.

Most of the time it happens with a bottle bought on the way home and poured in on the drive, not at the pump.

A couple of familiar ways account for most cases.

Hurrying, outside Kingsway Primary School, after a warning lamp flashed on during the school run, someone refills the vehicle.

Close to Herle Avenue, a driver tips a bottle in on that drive in the evening.

Otherwise, after dark outside The Bees Knees, the car gets topped up by someone using that flap the first time.

Rented vehicles, new cars, fleet vehicles, or the second car in a home with both fuels: the least known vehicles see it most.

Wherever around Leicestershire, Braunstone Town as well, the slip does not change, and neither does the first response: keep it off.

## Already started the engine with AdBlue in your diesel tank around Braunstone Town?

The AdBlue has left the tank, then.

With any running time, it goes on to the high-pressure pump and each injector, having passed through your filter and lines.

Lumpy running, smoke from the exhaust, dropping power, dashboard warnings or cutting out: any may show up, perhaps part way across Braunstone Town or coming back from Shakespeare Park.

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

Each start pulls more of that through.

On the M1, under a mile from Braunstone Town, the next junction is where to leave, and anywhere safe is where to park — not carrying on.

Hopping across Braunstone Town to the car park by Saint Peter's Braunstone Park is one thing; driving for Leicester, under 3 miles away, is another, since each mile pushes the AdBlue deeper in. So distance matters.

Tell us about how far it had come.

Wherever your car came to a halt is where all of it gets done, even with more to rinse out after the engine has been run.

If it is caught soon, permanent damage is very uncommon.

## Clearing AdBlue in a diesel around Braunstone Town: what it takes

A road by Braunstone Sure Start Children's Centre, a driveway, a lay-by or a filling station: anywhere the vehicle has stopped around Braunstone Town, our engineers travel to it.

The job rests on three answers, which our technicians ask for before all else — which fluid got in, the quantity, and if the motor has turned over.

Then that tank is cleared where your car waits, so the contaminated fuel and the AdBlue come out together.

A careful flush counts much more with AdBlue than with petrol, since residue will not clear away by itself.

A test of the vehicle comes last, after clean diesel is added and the filter is flushed or, if necessary, replaced.

If your engine hasn't run, most jobs take about half an hour once we arrive.

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

Lastly, your system is bled with new diesel.

Whether it is a parking space at Leicester or a driveway around Braunstone Town, that is where our engineers start it and you set off.

The test before our engineers head off is that it runs properly on new diesel.

The entire job is done where your car is, so it never has to be taken to a workshop.

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

## About Braunstone Town itself

Braunstone Town is a suburban area located on the outskirts of Leicester, situated near the River Soar in Leicestershire. Braunstone Town has a mix of housing types, but is predominantly composed of semi-detached homes. Braunstone Town is close to several nearby places, including Rowley Fields, Westcotes, and Braunstone Frith, and is about 2.2 miles from Leicester city centre. Braunstone Town sits at an elevation of around 85 metres above sea level.

## Braunstone Town and Leicestershire: AdBlue drains across the area

Throughout the LE postcode area, the teams taking AdBlue call-outs in Braunstone Town reach much of Leicestershire too, Rowley Fields, Westcotes and Braunstone Frith among them.

Near a border, or anywhere tricky to explain? Checking is better than assuming, so phone.

No moving is needed. In Braunstone Town, a residential suburb, a van that comes to you fits: the car is drained on the spot, be it on a drive, a residential street, a parking area or a filling station.

## What does AdBlue in a diesel tank cost to sort out in Braunstone Town?

Because the callouts differ, a flat figure would not be fair.

Whether the motor has been running, and for how long, comes first in what changes the cost. How much AdBlue went in comes next, and then the position of the car, because an open drive is simpler for a technician to reach safely than a tight spot behind Braunstone Civic Centre.

With that in mind, every enquiry from Braunstone Town opens by asking the same trio — which fluid was put in, how much, if it ran — before a quote.

Those answers turn a range into a straight quote.

Our quote is given during the call, before anyone leaves; settling up happens on the day, by card or over the phone, and nothing upfront.

As our engineer is on the way, dig out your policy: many include misfuelling.

## Still alongside your car around Braunstone Town?

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

Keys out; engine and ignition off.

Ring 0333 366 0103: AdBlue, the amount, and if the engine ran is all our technicians ask. Petrol in Diesel handles the rest across Leicestershire, Braunstone Town included.
