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

AdBlue in the diesel tank? Then keep the engine off — and the ignition as well.

Water with urea mixed in it: that's AdBlue.

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

In Rangeworthy, AdBlue in a diesel tank found before the engine runs usually means a drain and a thorough flush, right where the vehicle is.

No step comes before calling 0333 366 0103.

## AdBlue in the diesel tank around Rangeworthy: the first few minutes

Do these:

- So nobody can switch the ignition on, take the keys away.

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

- Which fluid, and roughly what quantity? Hang on to the bottle or the till receipt, and we can know.

- Call us from where you are. A postcode starting BS37 7, or the name of the nearest street, gets the van to you without a search.

Never do these:

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

- Your ignition remains off: on many diesels, switching it on is enough to start the fuel pump.

- Do not top up with diesel to thin it. AdBlue doesn't mix in diesel; it separates out.

- Keep the vehicle where it is instead of driving it anywhere, even a short stretch down B4058.

- Don't try to drain the vehicle yourself by the kerbside.

Ask the attendants to help you move your car off the island if you're on a forecourt in Rangeworthy, whether it's the Esso or somewhere else.

On your own drive, don't move it at all.

## What does AdBlue do in a diesel tank?

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

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

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

Inside a diesel tank it acts really differently from fuel. It doesn't mix in.

Denser than diesel, it sinks and collects below it — the same spot the pickup draws from.

A motor filled on a drive in Latteridge yesterday evening and not started since is the simple case. Nothing has sucked the AdBlue up yet — but once your motor turns, that's what goes first, straight from the bottom of your tank.

It causes two kinds of damage from there.

What remains when the water goes is urea, which turns into crystals: they lodge in narrow channels and block filters. On top of that, it eats at some metals in a fuel system, and keeps going till it's flushed out.

A motor left sitting in Rangeworthy with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't.

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

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

A fault of thinned fuel is what you get after fuelling a diesel with petrol from the Morrisons.

It mixes with your diesel, and while it's inside the tank it causes no damage; the damage comes from running the motor on it.

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

Because it does not burn, running it through is not an option.

Nor can it be watered down, because it splits back out — and the following fill will not rinse away crystals or corrosion. So the flush matters more here, and turning the key "to see", in the heart of Rangeworthy or out in Stidcot, does more harm than almost any other mistake.

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

If the motor has not run, the AdBlue is still inside that tank, and the tank is the quickest part of a fuel system to clear, wherever around Gloucestershire the vehicle is sitting.

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

Nobody means to do it. The AdBlue filler on plenty of cars sits right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light.

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

A few familiar ways cover most cases.

Rushing, outside Rangeworthy Church of England Primary School, after a warning lamp flashed on during the school run, someone refills your car.

Close to New Road, someone tips a container in at home in the evening.

Or a driver new to that flap tops up the car after dark, parked in the car park by Rose and Crown.

It comes up most in a hire car, a brand-new car, a company motor, or the other car of a home with one of each fuel types — the cars drivers use least.

An identical slip, an identical first response — keep it switched off — anywhere you happen to be in Rangeworthy or the remainder of Gloucestershire.

## Already started the motor with AdBlue in your diesel tank around Rangeworthy?

In that case, the AdBlue is no longer in that tank.

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

Perhaps coming back from Rangeworthy Playing fields, or midway across Rangeworthy, the engine may run rough, smoke, drop pace, light up your dash or cut out.

Stop as soon as it is safe, switch off, and do not restart it to check.

With each start, more of it is pulled through.

On the M5, under 3 miles from Rangeworthy, the next junction is where to exit, and anywhere safe is where to park — not driving on.

How far it went counts. A couple of hundred yards across Rangeworthy to the car park by Rangeworthy Village Hall is a very different job from a run towards Bristol, under 15 miles away, with the AdBlue reaching further into your system with each mile.

Roughly how far had it come? Tell us.

Once the motor has run, the flush includes more, and all of it is done where the vehicle has stopped.

When it is caught quickly, permanent damage is very uncommon.

## Rangeworthy: how AdBlue is emptied from a diesel

Our technicians come to your car, wherever it has stopped in Rangeworthy: a side street close to Holy Trinity, a drive, a lay-by or a forecourt.

Before anything else our engineers ask what got in, roughly how much, and whether your engine has run, since those answers determine this work.

The contaminated diesel and the urea come out together when your tank is emptied, on the spot.

Your system is purged thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own.

Next, the fuel filter: flushed, or changed if it must be. Then fresh diesel, and then a check of your car.

If your motor has not run, most jobs take about half an hour once we arrive.

Explosion-proof pumps make a live forecourt safe to work on, and they're quiet enough not to disturb the neighbours at night.

Fresh diesel goes in to bleed the fuel system, and that is the final step.

You head off as soon as we have fired it up, and it makes no difference whether the vehicle is on a drive around Rangeworthy or in a bay outside Yate.

We confirm it runs smoothly on new diesel before leaving.

The entire job is done where your car is, so it never has to go to a garage.

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

## About Rangeworthy itself

Rangeworthy is a small village in Gloucestershire, situated inland at an elevation of around 70 metres, approximately 10 miles from Bristol. Rangeworthy has a population of around 760 people, with predominantly detached housing. Rangeworthy is located near other small settlements such as Bagstone and Engine Common, and is about 100 miles west of London.

## AdBlue drains across Rangeworthy and Gloucestershire

The teams that answer AdBlue calls around Rangeworthy also cover the places round it, Bagstone, Engine Common and Iron Acton among them, and most of Gloucestershire beyond, across the BS postcode area.

Guessing won't help by a county line or anywhere hard to describe; phone and check.

No towing is needed. In Rangeworthy, a rural village, a mobile service fits: your car is emptied where it stands, be it in a drive, a residential street, a car park or a forecourt.

## What does AdBlue in a diesel tank cost to sort out in Rangeworthy?

No flat price could be fair, because each job differs.

What changes the cost is, first of all, whether the engine has been running and for how long; then how much AdBlue got in; and then where the vehicle is and whether our van can reach it safely, which is easier on an open drive than in a tight gap behind Acton Court.

That is why each call from Rangeworthy starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it has run.

With them, a range narrows to a single firm figure.

The price is given during the call, before a van sets off; settling up happens on the day, by card or by phone, with nothing upfront.

While the van is on the way, check your policy: many include misfuelling.

## Rangeworthy: still alongside the vehicle?

Then, do nothing — that is the best move available.

Motor off, keys out, ignition off.

Say it's AdBlue, roughly what quantity, and whether the engine ran, on 0333 366 0103. From there Petrol in Diesel takes over, in Rangeworthy or anywhere in Gloucestershire.
