# Dunston Hill: AdBlue in the Diesel Tank? Leave It Off

AdBlue in the diesel tank? Then leave the engine off — and your ignition as well.

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

Being water-based, it will not ignite and never combines with diesel; trouble just comes when your pump begins drawing it.

Caught before the motor has been run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the vehicle is around Dunston Hill.

Phone 0333 366 0103 before you do anything else.

## AdBlue in the diesel tank around Dunston Hill: the first few minutes

Things to do:

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

- Near moving traffic? So put the hazard lights on.

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

- Our van finds you quickest with a postcode starting NE11 9, or just the name of a street nearby, and so call from the car.

Not to do:

- Shifting your car just a short way is no reason to start the engine.

- Switching your key to ignition by itself sets your pump running on many diesels. Skip it.

- No extra fuel on top. The AdBlue will not blend, so it is pointless.

- Do not drive it anywhere, not even a short distance down Mountside Gardens.

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

The staff working at any Dunston Hill filling station — the Murco included — will normally help rolling it clear if you ask.

If you are on your own drive, leave it exactly where it stands.

## What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not your engine.

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

A fuel pump is not designed to take it, and AdBlue was never supposed to go through one.

It doesn't blend. Once it is tipped into the tank, AdBlue behaves nothing like diesel.

It sinks, since it is denser than diesel, and pools low where the intake takes its supply from.

A car topped up on a drive in Whickham yesterday evening and not started since counts as the straightforward case. No pump has pulled the AdBlue up yet — but when your engine turns, that's what goes first, directly from the bottom of the tank.

Two kinds of damage come from there.

Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filter elements and narrow passages; and, because it eats at some metals, every part it touches keeps suffering for as long as it stays in there.

If the AdBlue has reached the pipework, waiting till morning around Dunston Hill makes things worse. In your tank alone, waiting does nothing.

Water lubricates nothing. The injection pump and each injector depend on diesel running past them, so the water content harms them by itself.

## Why is AdBlue in a diesel regularly the bigger issue?

Put petrol in a diesel at the Esso and you have a fault of thin fuel.

No harm is done as long as it sits unused, mixed into your diesel — only once the engine runs on it.

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

Not burning, it cannot just be run through.

Whether the car is in Teams or the heart of Dunston Hill, firing it up "to see" does more harm in this case than nearly any other error, and the flush matters more. Why: it won't remain mixed, so watering it down fails; and crystals and corrosion survive the following fill.

The good news is the same as with petrol.

Anywhere across Tyne and Wear your vehicle has stopped, an unrun engine means the AdBlue yet inside the reservoir: the simplest part of any fuel system to empty.

## AdBlue in a diesel tank around Dunston Hill: how it ends up there

It is not on purpose. Many vehicles have the AdBlue inlet alongside the diesel one, now and then behind one flap, and muddling them up is easy in poor light.

It usually occurs at home, from a bottle bought en route home, not at the filling station.

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

A warning light comes on during the school run, and the top-up occurs in a hurry outside Dunston Hill Community Primary School.

After work, a container is tipped in on a drive close to Normount Road.

Or your car is topped up in the car park at The Highwayman, in poor light, by someone who has never opened that flap before.

It happens most in the motors people know least: a hire car, a new motor, a company car, or the second car of a household with one diesel and one petrol.

Wherever you're in Dunston Hill or the remainder of Tyne and Wear, it's the same slip and the same first answer: leave the vehicle off.

## Dunston Hill: started your engine with AdBlue in your diesel tank?

The AdBlue has left your tank, then.

It's been pulled through the filter and your lines, and if the motor ran for any time, it has got to your high-pressure pump and the injectors.

Perhaps coming back from Dunston Park, or part way across Dunston Hill, your motor may go lumpy, smoke, drop pace, light up the dash or stall.

When you safely can, pull over and switch everything off — with no turning it on again to see.

Each start pulls more of that through.

On the Central Motorway East, under 3 miles from Dunston Hill, the next junction is where to leave, and anywhere safe is where to park — not driving on.

Distance matters: each mile pushes the AdBlue deeper in, and so driving towards Newcastle upon Tyne, under 3 miles away, makes a much bigger job than hopping across Dunston Hill to the car park by Dunston Leisure Centre.

Let us know roughly how far it had come.

Our engineers do all of the rinsing where the vehicle has stopped, and once the motor has run there is more of it.

Long-term damage is very uncommon if it is noticed soon.

## Dunston Hill: how AdBlue is emptied from a diesel

Our technicians come to your car, wherever it has stopped around Dunston Hill: a side street close to Saint Nicholas With Christ Church, a drive, a lay-by or a forecourt.

The job depends on three answers, and our technicians get first — which fluid went in, the amount, and whether your motor has turned over.

The polluted diesel and the urea come out together after your tank is drained, on the spot.

The system is purged thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own.

After that, the filter: cleaned, or changed if it must be. Then fresh diesel, then a check of the car.

Engine not run? In that case expect roughly half an hour on site for most jobs.

Explosion-proof pumps make a live forecourt sensible to work on, and they're quiet enough not to disturb the street at night.

Last, the system is bled with clean diesel.

Whether it is a parking bay by Dunston or a driveway around Dunston Hill, that is where our engineers fire it up and you drive off.

Before we leave, our engineers make sure it is running correctly with fresh diesel in.

The entire job is done where the car is, so it never has to go to a workshop.

You get a VAT invoice and an engineer report later on, which is what insurers want.

## About Dunston Hill

## Dunston Hill and Tyne and Wear: AdBlue drains across the area

Our teams that answer AdBlue jobs around Dunston Hill also cover the spots about it, Dunston, Beechgrove and Lobley Hill among them, and most of Tyne and Wear beyond, across the NE postcode area.

Phone and ask instead of guessing if you are by a border, or somewhere awkward to pin down.

A van that comes to you fits Dunston Hill, a residential suburb: you have no need to bring your car to us, because we empty it there, on a drive, a residential street, a car park or a filling station.

## What AdBlue in a diesel tank costs to put right in Dunston Hill

Not one single price could be fair, since every job is different.

Whether the engine has been running, and for how long, comes first in what moves the cost. How much AdBlue was put in comes next, and then the position of the vehicle, because an open drive is simpler for a van to get to safely than a tight gap behind Dunston Monument.

For that in mind, every call from Dunston Hill opens with the identical trio — what went in, what quantity, if the engine ran — before a quote.

When those are answered, a range turns into a single firm number.

Quoted on the call before the van sets out, the job is paid for on the day — card or phone, nothing in advance.

While our engineer is travelling, dig out your policy: many cover misfuelling.

## Next to your car around Dunston Hill, still?

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

Keys out; engine and ignition off.

Petrol in Diesel handles the rest, in Dunston Hill or wherever within Tyne and Wear, after you ring 0333 366 0103 saying it's AdBlue, about what quantity, and if it ran.
