# AdBlue in the Diesel Tank in Langwith Junction? Keep It Switched Off

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

Chemically, AdBlue is just urea in water.

The trouble begins once it is sucked through your lines — it won't burn, and it will not blend with diesel.

Caught before the engine has been run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where your car is in Langwith Junction.

No step comes before calling 0333 366 0103.

## AdBlue in your diesel tank around Langwith Junction: the first few minutes

Do these:

- Pocket your keys, and that stops anyone switching the power on.

- Hazards on, if moving traffic is at all close.

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

- Call just where you are. Quote a NG20 9 postcode or the closest street name, and nobody has to hunt for you.

Not to do:

- Don't start your motor, even for a moment to shift the vehicle.

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

- No more fuel on top. The AdBlue will not blend, and so it's wasted.

- Do not drive the vehicle anywhere, not even a short stretch along Chatsworth Avenue.

- Do not try to drain the vehicle yourself by the roadside.

At a forecourt in Langwith Junction, whether it's the JET or another one, ask the staff to help you push the car clear of the pump.

On that drive, the car stays just as it is.

## AdBlue in a diesel tank: what it does

Meant for the exhaust, AdBlue has no business in the engine.

From a separate tank it is fed straight to your exhaust, treating what the motor emits.

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

Tipped in with the diesel, it keeps apart rather than blending — entirely unlike fuel.

The pickup sucks fuel from the lowest part of your tank, and that is exactly where AdBlue settles: being denser than diesel, it sinks.

A vehicle filled on a drive in Nether Langwith yesterday evening and left unstarted is the simple case. Nothing has pulled the AdBlue up yet — but once the engine turns, that is what is pulled first, directly from the bottom of that tank.

Two kinds of harm come from there.

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 till it is flushed out.

A car left sitting around Langwith Junction with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not.

Diesel lubricates the high-pressure pump and every injector as it passes; water gives none of that, and that is a second kind of damage.

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

Petrol put into a diesel on Texaco's forecourt makes your fuel watery — that is the main problem.

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

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

It cannot simply be run through, since it does not burn.

Whether the car sits in Whaley Thorns or the centre of Langwith Junction, turning it over "to see" does more harm with AdBlue than almost any other mistake, and the flush matters more. Why: it won't remain mixed, and so watering it down is impossible; and crystals and corrosion survive the following tankful.

The good news is the same as with petrol.

Anywhere in Derbyshire your vehicle has stopped, an unstarted engine leaves the AdBlue yet in the reservoir: the simplest bit of a fuel system to clear.

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

No one means to do it. The AdBlue filler on plenty of vehicles rests right next to your diesel filler, at times under the same flap, and the two caps can look alike in poor light.

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

The ways it occurs are few and familiar.

Hurrying, outside Brookfield Primary School, after a warning light came on during the school run, someone tops up the vehicle.

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

One more pattern: dim light, a pub car park outside The Badger, and someone opening that flap for the first time.

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

Wherever across Derbyshire, Langwith Junction included, the slip does not change, and nor does the first step: leave it off.

## AdBlue in your diesel tank in Langwith Junction, and the engine started?

Then the tank is no longer where the AdBlue is.

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

Maybe coming back from Lady's Grove, or part way across Langwith Junction, your engine may go lumpy, smoke, lose power, light up the dash or stall.

When safe, pull over then switch everything off — without restarting to see.

Each start pulls more of that through.

Leave the M1, under 5 miles from Langwith Junction, at the next junction and stop safely, rather than driving on.

How far it went matters. A couple of hundred yards across Langwith Junction to the car park by Shirebrook Village Hall is a very different job from a run towards Sheffield, under 25 miles away, with the AdBlue reaching further into your system with each mile.

Let us know roughly how far it had come.

There is more to flush once the engine has been started, and our technicians do all of it where your car has stopped.

Permanent damage is very rare if it is caught early.

## Langwith Junction: how AdBlue is drained from a diesel

The vehicle remains put, whether that's a street beside Kingsgate Centre, a driveway, a lay-by or a filling station around Langwith Junction, and our van comes to it.

The job depends on three replies, and we get first — what went in, the quantity, and if your motor has turned over.

Right there, the tank is then drained, and both the contaminated diesel and the urea come out at once.

What remains from AdBlue will not wash out unaided, so the fuel system gets a careful flush, which matters far more here than for petrol.

Fresh diesel goes in once your filter is flushed — or replaced, when it needs to be — and then the car is tested.

Not run? Then count on about half an hour once we are there for most jobs.

Quiet enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.

Bleeding the fuel system with new diesel comes last.

Whether it's a parking bay by Shirebrook or a drive around Langwith Junction, that is where we start it and you drive off.

It's checked on new diesel to make sure it runs smoothly before our technicians go.

As the job is done in full where the vehicle is, a garage never comes into it.

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

Langwith Junction is a residential suburb, and an on-site 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 is, and so it never needs to be shifted to us.

## What AdBlue in a diesel tank costs to put right around Langwith Junction

Every job differs, so no single quote is fair.

Whether your engine has been running, and for how long, comes first in what shifts the price. How much AdBlue was put in comes next, and then the location of the vehicle, because an open drive is simpler for a van to get to safely than a tight space behind Holy Cross.

Which fluid went in, what quantity, and if the engine ran: every Langwith Junction enquiry begins with exactly that, ahead of any quote, not afterwards.

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

Before anyone heads out, you are told the quote on the phone. Then you pay on the day, by card or over the phone, with nothing upfront.

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

## In Langwith Junction and still alongside the vehicle?

In that case, do nothing — that's the best move there is.

Motor off, keys out, ignition off.

Call 0333 366 0103 and tell us it's AdBlue, roughly how much, and whether it has run. Petrol in Diesel takes it from there, in Langwith Junction or anywhere around Derbyshire.
