# Don't Start It: AdBlue in a Diesel Tank in Fair Green

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

Water with urea mixed in it: that is AdBlue.

It does not burn, it doesn't mix with diesel, and the harm it does begins when your fuel system draws it in.

In Fair Green, AdBlue in a diesel tank found before your motor runs usually means a drain and a thorough flush, right where your car is.

Phone 0333 366 0103 before you do anything else.

## Fair Green, AdBlue in your diesel tank: what to do straight away

Things to do:

- So nobody can turn your ignition on, pull your keys out.

- If you are anywhere near moving traffic, put your hazards on.

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

- Our van locates you quickest with a postcode starting PE32 1, or just the name of a street nearby, so call from the car.

Not to do:

- Not even for a second, and not to shift your car: the engine stays off.

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

- No extra fuel on top. The AdBlue won't blend, so it is wasted.

- Any driving at all is best avoided, including a short stretch along Brookwell Springs.

- Emptying that tank on your own beside the road is not one to try.

The staff working at any Fair Green forecourt — the Esso among them — will normally lend a hand pushing it clear if you ask.

On your own driveway, don't touch it at all.

## What does AdBlue do in a diesel tank?

Not the motor but your exhaust is where AdBlue belongs.

From a dedicated reservoir it is fed straight to the exhaust, cleaning what your engine emits.

A fuel pump is not made to take it, and AdBlue was never intended to travel through one.

It doesn't blend. Once it is tipped into a tank of diesel, AdBlue behaves not at all like fuel.

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

A car filled on a drive in Blackborough End overnight and left unstarted is the simple one. No pump has pulled the AdBlue up yet — but once the motor runs, that is what goes first, straight from the bottom of the tank.

It does two kinds of harm from there.

Crystals and corrosion. As the water dries, it strands urea that crystallises in filter elements and narrow channels; and, since it eats at certain metals, each part it touches keeps suffering for as long as it remains inside.

If the AdBlue is in the lines, leaving it overnight in Fair Green leaves it worse. Inside your tank alone, waiting does nothing.

The water in it causes harm of its own: your high-pressure pump and your injectors rely on diesel to lubricate them, and water gives them nothing.

## Why AdBlue in a diesel is frequently more significant than petrol

Put petrol in a diesel at the Sainsbury's and you have a problem of thin fuel.

Damage just comes from running on it. Mixed into your diesel and sitting in your tank, it does nothing.

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

It doesn't burn, and so it cannot simply be run through.

Nor can it be watered down, since it splits again — and the next tankful won't rinse away crystals or corrosion. So the flush matters more with AdBlue, and trying the engine "to see", in the heart of Fair Green or out in Leziate, costs more than nearly any other error.

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 remains in there — anywhere around Norfolk the car has stopped.

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

After dark, two caps side by side — the AdBlue cap and the diesel cap, now and then under one flap — may appear the same. Nobody intends it; plenty of designs allow it.

Mostly it happens with a bottle bought on the way home and poured in on the drive, not at the pump.

Mostly, it takes place in one of a couple of familiar ways.

Hurrying, outside Middleton Church of England Primary Academy, after a warning lamp came on during the school run, a parent refills the vehicle.

Close to Graham Drive, a driver pours a container in on the drive in the evening.

Or the vehicle is topped up in the car park at The Gate Inn, in poor light, by a person who has never opened that flap before.

It comes up most in a hire car, a brand-new vehicle, a fleet vehicle, or the spare motor in a home with one of each fuels — the vehicles drivers know least.

An identical slip, same first step — leave it off — anywhere you are around Fair Green or the remainder of Norfolk.

## Already started the motor with AdBlue in the diesel tank in Fair Green?

If so, the AdBlue is no longer inside the tank.

Via your filter, through the lines, and — given any running time — on to the high-pressure pump and every injector: that is how far it travels.

You may notice the engine running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Middleton Hall Golf Club or halfway across Fair Green.

Stop as soon as it is safe, switch off, and don't restart the vehicle to check.

Every start pulls more of it through.

If you were on the A1(M), under 50 miles from Fair Green, come off at the next junction and stop somewhere safe instead of pressing on.

Distance matters: each mile pushes the AdBlue deeper in, and so heading for Ely, under 25 miles away, makes a much bigger job than hopping across Fair Green to the car park by Middleton Mount Motte and Bailey Castle.

About how far it had come is worth telling us.

Wherever your car came to a halt is where all of it gets done, even with more to flush after the motor has been run.

Noticed soon, it very rarely leaves lasting damage.

## What emptying AdBlue from a diesel involves around Fair Green

The car stays put, whether that is a street near Saint Mary, a drive, a layby or a forecourt in Fair Green, and the van comes to it.

Before anything else we ask what went in, roughly how much, and if the engine has run, since those answers decide the work.

Then that tank is drained where your car sits, and so the polluted fuel and the AdBlue come out together.

With AdBlue, far more than with petrol, flushing matters: the whole system is cleaned right through since residue will not wash out unaided.

Clean diesel goes in once your filter is flushed — or replaced, if it needs to be — and after that your car is tested.

Roughly half an hour on site is usual for most jobs when the motor hasn't run.

Low-noise enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.

Fresh diesel goes in to prime your system, and that's the final step.

You set off as soon as our engineers have fired it up, and it makes no difference whether the vehicle is on a drive around Fair Green or in a bay at Kings Lynn.

The check before we go is that it runs smoothly on fresh diesel.

The whole job is done where your car is, so it never needs to be taken to a workshop.

The insurer will want an engineer's report and your VAT invoice — both yours afterwards.

## About Fair Green itself

Fair Green is a small suburban area in Norfolk, situated inland at a low elevation of around 9 metres. Fair Green lies near several nearby villages, including Middleton, Tower End, and North Runcton, and is within commuting distance of the city of Ely. Fair Green has a population of approximately 565 people, predominantly living in detached housing. Fair Green is also relatively close to the regional transport networks, being about 87 miles from London.

## AdBlue drains across Norfolk, Fair Green included

Middleton, Tower End and North Runcton are among the towns near Fair Green that the same vans serve, along with much of Norfolk beyond, throughout the PE postcode area.

Assuming won't help close to a county line or anywhere hard to pin down; ring and check.

Wherever the car sits — a drive at home, a residential street, a parking area, a forecourt — our technicians empty it on the spot, and there's no need to take it to us; which suits Fair Green, a residential suburb, well.

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

Because each jobs differ, a flat price would not be fair.

The cost changes first with how long, if at all, the motor has been running, and next with the amount of AdBlue that was put in. After that it depends on where the vehicle is and whether our van can reach it safely, which is simpler on an open driveway than in a tight spot behind Middleton Village Hall.

That is why each call from Fair Green starts with the same three questions, asked before giving a figure, not after: what went in, how much, and whether it has run.

With those replies, a range narrows to a single fixed number.

Quoted by phone before the engineer heads out, it is paid for on the day — card or phone, nothing in advance.

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

## Alongside the vehicle in Fair Green, right now?

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

Ignition off, engine off, keys out.

Tell us it's AdBlue, about how big an amount, and if it ran, on 0333 366 0103. After that Petrol in Diesel takes over, in Fair Green or wherever within Norfolk.
