# Don't Start It: AdBlue in a Diesel Tank in The Barton

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

Urea dissolved in water is what AdBlue is.

Unlike fuel, it neither burns nor mixes, and no harm happens till your motor sucks it through.

If the motor has not run yet, AdBlue in a diesel tank is usually drained and carefully rinsed where the car sits around The Barton.

Before you do anything else, ring 0333 366 0103.

## AdBlue in your diesel tank in The Barton: the first few minutes

To do:

- Remove the keys, and that stops someone switching the electrics on.

- Close to moving traffic? Then put the hazards on.

- The empty bottle or your receipt shows us the product and the amount, so don't throw it away.

- The van finds you fastest with a postcode starting GL9 1, or just the name of a street nearby, so phone from the spot.

Never:

- Not even for a second, and not to roll the car: your engine remains off.

- Switching the key to ignition alone starts the pump running on many diesels. Avoid it.

- AdBlue does not dilute in diesel — it separates out — so adding more diesel will not weaken it.

- Never drive the car anywhere, not even a short distance up The Barton.

- No emptying it yourself, either, on the roadside.

On a forecourt around The Barton, whether it's the BP or another one, ask the staff to help you roll the vehicle away from the pump.

At home, your car stays just where it is.

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

The engine is not what AdBlue is made for; the exhaust is.

Its own reservoir keeps it, and from there it is sprayed into your exhaust, and there it treats the fumes.

Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Fuel blends; AdBlue, after poured in, won't. The behaviour is nothing like diesel's.

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

When your pump runs, the AdBlue is first to be pulled through. Before then it sits underneath your diesel, which is why a car topped up in Orange End last night and not switched on stays the simple one, as long as nobody touches your key.

Once it's pulled in, the harm comes in two forms.

It eats at certain metals used in fuel systems, attacking whatever it reaches until it's cleared from your system. And when the water goes, the urea turns into crystals that clog filters and lodge in tiny passages.

By daybreak, a vehicle sitting in The Barton with AdBlue through its pipework grows worse; if it is just in that tank, it doesn't.

Water lubricates nothing. The high-pressure pump and every injector need diesel flowing past them, so the water content damages them in its own right.

## Why AdBlue in a diesel is regularly more serious than petrol

Fill a diesel with petrol by mistake at the Harvest Energy, and this issue is thinned fuel.

Damage just comes from driving on it. Mixed into the diesel and left in your tank, it does none.

With AdBlue in a diesel, the fluid itself is simply the wrong one.

Not burning, it can't simply be run through.

Nor can it be watered down, since it splits back out — and the following fill won't rinse away deposits or corrosion. So the flush counts more with AdBlue, and turning the key "to see", in the centre of The Barton or out in Dunkirk, costs more than almost any other slip.

As with petrol, there is good news.

Emptying a tank is the easiest part on any fuel system, and with no running, the AdBlue stays in it — wherever across Gloucestershire the car sits.

## How AdBlue ends up in a diesel tank in The Barton

Many cars place the AdBlue cap alongside the diesel one, now and then behind one flap, and after dark the two may appear the same. Nobody means it.

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

The ways it occurs are few and familiar.

Rushing, outside Hawkesbury Church of England Primary School, after a warning light flashed on during the school run, someone tops up the car.

Someone pours the container in outside their house, just off High Street, as the day ends.

Else, after dark outside Beaufort Arms, your vehicle gets topped up by someone using that flap the first time.

The least known cars get it most — hire cars, brand-new cars, fleet cars, and the spare car of a home with one of each fuels.

Wherever around Gloucestershire, The Barton included, the slip doesn't change, and neither does the first response: leave it switched off.

## AdBlue in the diesel tank in The Barton, and the motor started?

The AdBlue has left your tank, then.

The fuel filter and lines have had it sucked through, and some running time carries it on to the injection pump and each injector.

Maybe returning from Hawkesbury Upton Tennis Club, or midway across The Barton, your engine might run lumpy, smoke, lose pace, flash your dash or stall.

No restarting to test: stop when safe, then switch everything off.

Each start pulls more of it through.

Exit the M4, under 10 miles from The Barton, by the next junction and park somewhere safe, not carrying on.

Each mile pushes the AdBlue further into the system. That's why a hop across The Barton to park near Hawkesbury Upton Village Hall and a drive of under 15 miles for Bath are such separate jobs.

Roughly how far it had come is worth telling us.

Our technicians do all of the rinsing where your car has ended up, and once the motor has been started there is more of it.

Very seldom does it leave lasting damage if it is spotted soon.

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

Our technicians come to the car, wherever it has stopped in The Barton: a side street near Hawkesbury Upton Methodist Chapel, a drive, a lay-by or a forecourt.

The work depends on three answers, which our technicians get before all else — what was put in, the quantity, and if your motor has run.

Next, draining the tank on the spot removes the contaminated diesel along with the AdBlue together.

A careful flush counts much more with AdBlue than with petrol, because residue won't clear out by itself.

Next, the filter: flushed, or replaced if it must be. After that clean diesel, and then a test of your car.

Roughly half an hour on site is usual for most jobs where the motor hasn't run.

Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough to spare the neighbours at night.

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

After that our engineers start the car and you set off, whether from a parking bay by Yate or a driveway in The Barton.

Our technicians make sure it runs correctly on clean diesel before leaving.

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

Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

## About The Barton and where it is

The Barton is a suburban area in Gloucestershire, situated inland at an elevation of 196 metres, with detached housing being the predominant type of accommodation. The Barton lies approximately 13.9 miles from the city of Bath and 94.6 miles from London, placing it in a rural yet accessible location. The Barton is surrounded by nearby places such as Hawkesbury Upton, Hawkesbury, and Britain Bottom, and has a population of around 1025 residents.

## AdBlue drains across The Barton and Gloucestershire

AdBlue call-outs around The Barton go to teams that cover the towns near it — Hawkesbury Upton, Hawkesbury as well as Britain Bottom — and most of Gloucestershire further out, throughout GL postcodes.

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

The Barton is a residential suburb, and a mobile drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it sits, and so it never needs to be shifted to us.

## What AdBlue in a diesel tank costs to put right in The Barton

Not one flat figure could be honest, since each job differs.

The price moves first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that was put in. After that it rests on where your car is and whether our van can reach it safely, which is simpler on an open drive than in a tight space behind Somerset Monument.

Before a quote, not after, each call from The Barton begins with the same three questions: the liquid, the amount, and if the engine ran.

Once they are known, a range turns into a single fixed number.

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

While the van is on the way, dig out your insurance: plenty include misfuelling.

## Beside your car in The Barton, still?

In that case, touch nothing — that is the most helpful step available.

Ignition off, motor off, keys out.

Say it's AdBlue, about what quantity, and if it ran, on 0333 366 0103. After that Petrol in Diesel handles it, across The Barton or wherever in Gloucestershire.
