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

Motor off, ignition off: that's how you start if AdBlue has got into your diesel tank.

AdBlue is urea mixed in water.

The trouble begins once it's pulled through your pump — it will not burn, and it will not blend with diesel.

Caught before the engine has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where your car is around Neston.

Phone 0333 366 0103 before you do anything else.

## What to do straight away, Neston: AdBlue in your diesel tank

To do:

- Remove your keys, which prevents anyone switching the electrics on.

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

- So you can tell us which liquid it was and roughly how much, keep the till receipt or the empty bottle.

- Call us from where you are. A postcode starting CH64 9, or the name of the closest street, gets the van to you without a search.

Not to do:

- No starting your motor — not briefly, not to shift your car.

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

- No extra fuel added. The AdBlue won't blend, so it's wasted.

- Don't drive it anywhere, not even a short distance along Brook Street.

- Emptying that tank yourself by the road isn't worth trying.

On a forecourt around Neston, whether it is the Shell or another one, ask the staff to help you roll your car away from the pump.

At home, your car remains exactly where it is.

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

The engine isn't what AdBlue is made for; your exhaust is.

From a dedicated tank it is fed straight to your exhaust, cleaning what your engine lets out.

Nothing in an injection pump is made for this fluid — and none of that was meant to go that way.

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

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

The first thing the system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Parkgate last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has drawn it in.

It causes two kinds of harm from there.

What remains when the water goes is urea, which forms crystals: they settle in narrow passages and block filters. Worse, it eats at some metals in the fuel system, and carries on till it is flushed out.

A vehicle left standing around Neston 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 damage of its own: the high-pressure pump and the injectors depend on diesel to lubricate them, and water offers them nothing.

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

Petrol pumped into a diesel on Gordale Petrol Station's forecourt leaves your fuel thin — that is the whole issue.

It mixes with the diesel, and whilst it is inside the tank it causes no damage; the damage comes from running your engine on it.

AdBlue in a diesel is a fault of the wrong substance altogether.

Not burning, it cannot simply be run through.

It does not stay mixed, and so it can't be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting the motor "to see" costs more here than almost anywhere else, whether the car is in Ness Holt or the middle of Neston.

As with petrol, there's good news.

Clearing a tank is the easiest part on any fuel system, and without running, the AdBlue stays in there — anywhere across Cheshire the vehicle sits.

## How does AdBlue end up in a diesel tank around Neston?

Many vehicles place the AdBlue filler beside the diesel cap, occasionally under one flap, and in dim light the two may look the same. No one means it.

Usually it is never the forecourt: a driver picks up a bottle heading home and tips it in outside the house.

The ways it takes place are few and familiar.

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

A bottle is poured in at the end of the day on a drive just off High Street.

Or someone new to that flap refills your car after dark, stopped in the car park by The Brown Horse.

The least familiar vehicles get it the most — hire cars, brand-new cars, fleet ones, and the other car of a family with one of each fuel types.

Anywhere around Cheshire, Neston as well, the mistake doesn't change, and neither does the first response: keep it switched off.

## Started the engine with AdBlue in your diesel tank in Neston?

The AdBlue has left the tank, then.

With any running, it travels to the injection pump and each injector, having passed through the fuel filter and lines.

Lumpy running, smoke from the exhaust, lost power, dashboard lights or cutting out: each might show up, perhaps part way across Neston or coming back from Comrades Field.

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

Each start pulls more of that through.

Leave the M53, under 3 miles from Neston, at the first junction and park somewhere safe, rather than driving on.

Hopping across Neston to the car park by The Bushell Fountain is one matter; driving towards Liverpool, under 10 miles away, is another, since every mile pushes the AdBlue further in. So distance matters.

About how far it had come is worth telling us.

Once your engine has been started, the flush covers more, and all of it is done where the car has stopped.

When it's caught quickly, lasting damage is very uncommon.

## What clearing AdBlue from a diesel involves around Neston

Our technicians come to your car, wherever it has stopped in Neston: a side street near St. Mary and St. Helen Neston Parish Church, a drive, a lay-by or a forecourt.

The job rests on three answers, which our engineers ask for before all else — which fluid went in, the quantity, and whether the engine has run.

Then the tank is emptied where the vehicle waits, so the tainted fuel and the AdBlue come out together.

A full flush counts far more with AdBlue than after petrol, since what remains won't clear out by itself.

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

About half an hour once we arrive is typical for most jobs when your motor has not run.

Low-noise enough for use outside a house at night, and fine on a busy forecourt, the pumps are explosion-proof.

Lastly, the fuel system is primed with clean diesel.

You set off as soon as we have fired it up, and it makes no difference whether your car is on a driveway in Neston or in a space outside the nearest station.

Before we leave, our engineers check it is running correctly with clean diesel in.

Because the job is done in full where the car is, a workshop never comes into it.

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

## About Neston, briefly

Neston is a coastal town in Cheshire, situated near the Dee Estuary and approximately 9 miles from Liverpool. Neston has a population of around 13137 people and is characterised by predominantly detached housing. Neston sits at an elevation of 37 metres, with nearby places including Moorside, Little Neston, and Hinderton. Neston is located in the North West region of England, about 174.6 miles from London.

## Neston and Cheshire: AdBlue drains across the area

Over the CH postcode area, the vans answering AdBlue call-outs around Neston serve most of Cheshire as well, Moorside, Little Neston and Hinderton included.

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

Anywhere your vehicle stands — your drive at home, a side street, a parking area, a filling station — our technicians drain it on the spot, and there's no need to bring it to us; that suits Neston, a coastal town, well.

## Neston: what AdBlue in a diesel tank costs to fix

Because the callouts differ, a flat price would not be honest.

Whether the motor has run, and for how long, comes first in what changes the price. How much AdBlue got in comes next, and then the position of your car, because an open drive is simpler for a technician to reach safely than a tight space behind Neston Town Hall.

For that in mind, every call from Neston begins with the identical trio — what got in, what quantity, if the engine ran — before a figure.

Their replies narrow a range right down to a single number.

Before a van heads out, you hear our quote on the phone. And payment is on the day, card or over the phone, with nothing upfront.

Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.

## Neston: still next to your car?

Then the most handy thing you can do is nothing to the vehicle.

Ignition off, engine off, keys out.

Tell us it's AdBlue, roughly what quantity, and if the engine ran, on 0333 366 0103. After that Petrol in Diesel takes over, in Neston or anywhere in Cheshire.
