# Don't Start It: AdBlue in a Diesel Tank in Nether Langwith

AdBlue in your diesel tank? Then keep your engine off — and your ignition too.

AdBlue is urea mixed in water.

Unlike fuel, it neither ignites nor blends, and no harm happens until the engine sucks it round.

If your engine has not run yet, AdBlue in a diesel tank is normally drained and carefully rinsed where the vehicle stands around Nether Langwith.

Before you do anything else, call 0333 366 0103.

## What to do right now, Nether Langwith: AdBlue in your diesel tank

To do:

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

- If you are anywhere near moving traffic, put the hazard lights on.

- The empty bottle or the receipt tells us the product and the quantity, so do not bin it away.

- Ring us from where you are. A postcode starting NG20 9, or the name of the nearest street, brings the van to you without a search.

Never:

- No starting the engine — not briefly, not to reposition the vehicle.

- Plenty of diesels power their fuel pump the moment the ignition comes on, and so leave the car off.

- Adding extra diesel does not work: AdBlue settles out instead of blending.

- Leave the car where it is instead of driving it anywhere, even a short way up Queens Walk.

- Emptying your tank on your own beside the road is not worth trying.

The staff on duty at any Nether Langwith forecourt — the JET among them — will normally lend a hand pushing it aside if you ask.

At your own drive, do not touch it at all.

## What AdBlue does in a diesel tank

Made for the exhaust, AdBlue has no business in your engine.

Stored in a separate tank, it is squirted into the exhaust stream to clean the fumes.

A fuel pump isn't designed to take it, and AdBlue was never intended to travel through one.

Fuel blends; AdBlue, after tipped in, won't. The behaviour is not at all like fuel's.

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

The first thing the fuel system pulls through, once it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Langwith last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in.

Two kinds of damage come from there.

Crystals and corrosion. As the water evaporates, it strands urea that hardens in filter elements and narrow channels; meanwhile, because it eats at some metals, each part it touches keeps suffering for as long as it remains in there.

A car left sitting around Nether Langwith with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't.

And there is the water: it offers no protection to the parts that rely on it the most — the injection pump and every injector.

## Petrol or AdBlue in a diesel: why AdBlue is frequently worse

Top up a diesel with petrol by mistake over at the Welbeck Service Station, and this issue is thinned fuel.

It mixes with the diesel, and whilst it's in that tank it causes no harm; the harm comes from running the engine on it.

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

Because it does not burn, running it through isn't an option.

Whether your car sits in Whaley or the heart of Nether Langwith, turning it over "to see" costs more in this case than nearly any other error, and the flush matters for more. Why: it will not stay blended, and so diluting it fails; and crystals and corrosion survive the next tankful.

With AdBlue, the good news is no different from petrol.

If your engine has not run, the AdBlue is still in the tank, and your tank is the quickest part of a fuel system to clear, wherever around Nottinghamshire the car is standing.

## How AdBlue ends up in a diesel tank in Nether Langwith

Nobody means to do it. The AdBlue filler on plenty of cars sits right next to your diesel filler, occasionally 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 drive, not at the pump.

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

A warning light comes on during the school run, and the top-up happens in a hurry outside Whaley Thorns Primary School.

After work, a container goes in on a drive near Main Road.

Another version: dim light, the car park by Jug and Glass, and someone using that flap for the first time.

It takes place most in the cars motorists 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 are around Nether Langwith or the rest of Nottinghamshire, it's the same mistake and the same first answer: leave the vehicle off.

## Already started your engine with AdBlue in your diesel tank around Nether Langwith?

The AdBlue has left that tank, then.

Through the filter, along the lines, and — with any running time — on to the high-pressure pump and each injector: that is how far it travels.

You may see your engine running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Boon Hills Wood or halfway across Nether Langwith.

When safe, stop and turn it off — with no restarting to see.

Each start pulls more of that through.

Exit the M1, under 10 miles from Nether Langwith, at the first junction and park somewhere safe, not driving on.

Hopping across Nether Langwith to the car park by War Memorial is one thing; driving for Sheffield, under 25 miles away, is something else, since every mile pushes the AdBlue further in. So distance matters.

Tell us roughly how far it had come.

There is more to rinse out once the engine has been run, and our engineers do all of it where your car has ended up.

If it is noticed early, long-term damage is very rare.

## What clearing AdBlue from a diesel involves around Nether Langwith

We come to the car, wherever it has stopped around Nether Langwith: a side street close to Whaley Thorns & Langwith Village Hall, a drive, a lay-by or a forecourt.

Before anything else our technicians ask what was put in, roughly how much, and whether the engine has been run, since those answers settle the work.

Right there, that tank is then emptied, and all of the polluted diesel and the urea leave as one.

The system is flushed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own.

Testing the vehicle comes at the end, after clean diesel is added and the filter gets cleaned or, where necessary, replaced.

Engine not run? Then expect about half an hour on site for most jobs.

The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house after dark.

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

You set off as soon as we have fired it up, and it makes no difference whether your car is on a drive in Nether Langwith or in a bay by Langwith - Whaley Thorns.

The check before we head off is that it runs properly on new diesel.

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

At the end, you are given the paperwork for your insurer: a VAT invoice plus a report from the engineer.

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

There is no fair single quote, since the jobs aren't the same.

Whether the engine has been running, and for how long, comes first in what moves the cost. How much AdBlue got in comes next, and then the position of the car, because an open driveway is easier for a van to get to safely than a tight gap behind Langwith Whaley Thorns Heritage Centre.

For that reason, every enquiry from Nether Langwith opens by asking the identical trio — what went in, what quantity, whether it ran — ahead of any figure.

Once they are known, a range becomes one firm number.

Our quote is given during the call, before a van sets off; payment comes on the day, by card or by phone, with nothing upfront.

Misfuelling cover is part of many insurance policies, so it pays to look at yours before the van gets there.
