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

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

Urea mixed in water is what AdBlue is.

The trouble starts once it's pulled through the pump — it will not ignite, and it won't blend with diesel.

In Darland, AdBlue in a diesel tank caught before your motor runs normally means a drain and a thorough flush, just where your car is.

Before you do anything else, call 0333 366 0103.

## Those opening minutes: AdBlue in your diesel tank in Darland

To do:

- So no one can switch your ignition on, pull your keys away.

- Close to moving traffic? So put the hazard lights on.

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

- Our van finds you fastest with a postcode starting LL12 0, or just the name of a street nearby, so phone from the spot.

Do not do these:

- Not even briefly, and not to roll the car: the engine remains off.

- Your ignition stays off: on many diesels, turning it on is enough to run the fuel pump.

- Pouring in more diesel doesn't work: AdBlue settles out instead of thinning.

- Never drive it anywhere, not even a short way down Darland Lane.

- Beside the road, do not try draining it yourself.

The attendants on duty at any Darland filling station — the BP among them — will normally help pushing it aside if you ask.

At home, your car remains exactly as it was left.

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

Not the motor but your exhaust is where AdBlue belongs.

It goes into its own tank and is sprayed into your exhaust gas to clean it.

Nothing inside an injection pump is made for this fluid — and no part of that was intended to travel through one.

Fuel blends; AdBlue, once poured in, will not. Its behaviour is not at all like fuel's.

Denser than diesel, it sinks and collects below it — the very place the pickup draws from.

Simplest of all: a vehicle that got AdBlue in Broadoak overnight and hasn't turned since. The liquid waits at the base of the tank, untouched — but it would be the first thing through if the motor runs, before any diesel at all.

From there it does two kinds of harm.

What is left when the water evaporates is urea, which turns into crystals: they lodge in tiny channels and block filters. Worse, it eats at certain metals in a fuel system, and keeps going until it is flushed out.

Pipes holding AdBlue spell harm overnight for a car sitting around Darland. Only inside your tank, it stays the same.

Water lubricates nothing. The high-pressure pump and every injector depend on diesel flowing through them, so the water part damages them in its own right.

## Why is AdBlue in a diesel commonly the bigger fault?

Petrol put into a diesel on Gulf's forecourt leaves your fuel thin — that is the main fault.

Damage only comes from running on it. Mixed into your diesel and sitting inside that tank, it does nothing.

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

It does not burn, and so it can't simply be run through.

Deposits and corrosion stay after the following tankful, and AdBlue separates again from the diesel, and so watering it can't help. Hence the flush counts more, and trying your engine "to see" does more harm with AdBlue than nearly any other slip — in Trevalyn or the centre of Darland alike.

The good news is the same as with petrol.

Clearing a tank is the easiest part on a fuel system, and without running, the AdBlue stays in there — wherever in Wrexham your vehicle sits.

## How AdBlue ends up in a diesel tank around Darland

No one means to do it. The AdBlue filler on many motors sits right next to the diesel filler, occasionally under the same flap, and the two caps can look alike in poor light.

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

The ways it occurs are few and familiar.

The refill is rushed outside Dodleston CofE Primary School, after your dash flashed with a warning as the kids were dropped in.

Near Gamford Lane, someone tips a bottle in on that drive after work.

Another version: darkness, a pub car park by The Dog and Pickle, and someone opening that flap for the first time.

It takes place most in the cars motorists know least: a hire car, a new vehicle, a company car, or the second car of a household with one diesel and one petrol.

Keep it off: that's the first step to the same slip, anywhere in Darland or the remainder of Wrexham you happen to be.

## Darland: started the motor with AdBlue in the diesel tank?

Then that tank is no longer where the AdBlue is.

Through your filter, through the pipework, and — given any running — on to the injection pump and every injector: that is how far it has gone.

Perhaps coming back from Marford Wood, or midway across Darland, your engine might go rough, smoke, lose power, light up your dash or cut out.

No restarting to test: pull over once safe, then switch everything off.

Each start pulls more of it through.

If you were on the M53, under 10 miles from Darland, come off at the next exit and stop somewhere sensible rather than pressing on.

A quick hop across Darland to the car park by Darland Leisure and Activity Centre is one matter; driving for Wrexham, under 10 miles away, is another, because every mile pushes the AdBlue deeper in. So distance counts.

Let us know roughly how far it had come.

Our engineers do all of the rinsing where the vehicle has come to a stop, and once your engine has been started there is more of it.

Caught quickly, it very rarely leaves lasting damage.

## What does an AdBlue drain on a diesel involve in Darland?

A street beside Hwb Yr Orsedd, a driveway, a lay-by or a filling station: wherever the car has stopped in Darland, our technicians travel to it.

Before anything else our engineers ask what went in, about how much, and if the engine has run, since those replies settle the work.

Next, emptying your tank right there takes out the polluted diesel and the AdBlue in one go.

Your system is cleaned thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own.

Next, your filter: flushed, or replaced when it must be. After that clean diesel, then a test of your vehicle.

About half an hour on site is typical for most jobs where the engine hasn't run.

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

Clean diesel goes in to bleed the fuel system, and that's the last step.

You drive off as soon as we have started it, and it makes no difference whether the car is on a driveway around Darland or in a bay outside Caergwrle.

It's tested on clean diesel to confirm it runs correctly before our engineers go.

As the job is done in its entirety where the car is, a garage never comes into it.

The insurer will want an engineer's report and the VAT invoice — each handed over afterwards.

## About Darland itself

Darland is a small village situated on the riverside in Wrexham county, with an elevation of around 11 metres. Darland lies close to the nearby villages of Lavister, Rossett, and Pulford, and is approximately 5.2 miles from Wrexham. Darland has a population of around 940 people and is characterised by predominantly detached housing. Darland is located in a region that is relatively close to the English border, with London being around 162.4 miles away.

## AdBlue drains in Darland and across Wrexham

AdBlue call-outs in Darland are passed to teams that cover the places around it — Lavister, Rossett plus Pulford — and much of Wrexham beyond, throughout LL postcodes.

If you're near a border, or somewhere hard to describe, ring and ask rather than assuming.

No moving is needed. In Darland, a village, a van that comes to you works: the vehicle is drained where it stands, be it on a drive, a side street, a parking area or a filling station.

## AdBlue in a diesel tank in Darland: the cost of fixing it

There is no fair single price, because the jobs aren't the same.

What moves the cost is, first, whether the motor has been running and for how long; then how much AdBlue went in; and after that where the vehicle is and whether a van can reach it safely, which is simpler on an open drive than in a tight spot behind Pulford Castle.

What got in, how much, and if the engine ran: every Darland enquiry opens with precisely those, ahead of any quote, not afterwards.

Their replies shrink the range down to a single number.

Priced on the call before the van sets out, it is settled that day — card or phone, no deposit.

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

## Darland: still next to the car?

In that case, touch nothing — that's the best move available.

Engine off, keys out, ignition off.

Ring 0333 366 0103: AdBlue, roughly how much, plus if the engine ran are all our technicians ask. Petrol in Diesel handles the remainder across Wrexham, Darland too.
