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

If AdBlue has gone into your diesel tank, leave your motor off and leave your ignition off.

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

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

A drain and a thorough flush, done where the car is around Broughton, is generally what AdBlue in a diesel tank needs — if it is caught before the engine has run.

Before you do anything else, ring 0333 366 0103.

## Your next steps right now, Broughton: AdBlue in the diesel tank

Do:

- Pull the keys out, so nobody switches the ignition on.

- Put your hazards on if you are at all close to moving traffic.

- Which fluid, and about what amount? Hang on to the bottle or the receipt, and our engineers can know.

- Our van finds you quickest with a postcode starting SO20 8, or simply the name of a street close by, and so phone from the car.

Don't do these:

- Moving your vehicle just a few yards is no reason to start your motor.

- Switching your key to ignition alone starts the pump running on many diesels. Skip it.

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

- Any driving at all is best avoided, even a short stretch up Chapel Lane.

- No draining it yourself, either, at the verge.

Moving your vehicle off the pumps is a job for staff to help with, wherever Broughton forecourt you are on, the Pace or any other.

If you are on your own drive, leave the car just where it is.

## What does AdBlue do in a diesel tank?

AdBlue is made for your exhaust, not your motor.

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

Neither side suits the other: urea does not belong in a pump, and an injection pump can't take urea.

Fuel blends; AdBlue, after poured in, won't. Its behaviour is nothing like diesel's.

It drops, since it's heavier than diesel, and pools low where the pickup draws its fuel from.

Simplest of all: one that had AdBlue in North Houghton last night and has not turned since. The liquid waits at the base of your tank, undrawn — but it would be the first thing through once the engine runs, before any diesel at all.

Once it is sucked in, the harm takes two forms.

It attacks certain metals used in fuel components, attacking any part it touches until it is cleared from the system. And once the water goes, the urea turns into crystals that clog filters and lodge in tiny channels.

Where the AdBlue is in the pipework, waiting overnight in Broughton makes it worse. In your tank alone, waiting does nothing.

Water lubricates nothing. The high-pressure pump and every injector depend on diesel flowing through them, and so the water content damages them by itself.

## AdBlue in a diesel: why it is frequently worse than petrol

Petrol put into a diesel on another forecourt nearby's forecourt leaves your fuel watery — that is the main fault.

Damage just comes from running on it. Blended into the diesel and sitting in your tank, it does none.

With AdBlue in a diesel, the fluid as such is plainly the wrong one.

It can't simply be run through, because it does not burn.

Crystals and corrosion remain after the following fill, and AdBlue separates back from the diesel, so watering it can't work. Hence the flush matters so much, and turning the key "to see" does more harm with AdBlue than almost any other mistake — in Danebury or the heart of Broughton alike.

The good news is the same as with petrol.

Clearing a tank is the easiest part on any fuel system, and without running, the AdBlue remains in it — wherever across Hampshire your car has stopped.

## AdBlue in a diesel tank around Broughton: how it ends up there

It is not deliberate. Many vehicles have the AdBlue inlet beside the diesel one, now and then under one flap, and mixing them up is easy after dark.

It mostly happens at home, from a bottle grabbed on the journey home, rather than at the filling station.

A few familiar ways account for the majority of them.

The top-up gets hurried outside Broughton Primary School, after the dash flashed with a warning as the kids were taken off.

Near High Street, a driver tips a container in on that drive after work.

Or a driver new to that flap tops up your vehicle in dim light, stopped in the car park outside The Greyhound.

It comes up most in a rental, a new vehicle, a company car, or the other vehicle in a home with both fuels — the vehicles drivers use the least.

Same slip, an identical first step — leave it switched off — anywhere you are around Broughton or the rest of Hampshire.

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

Then the AdBlue has left the tank.

The fuel filter and lines have had it sucked through, and some running takes it on to the injection pump and each injector.

You may see the engine running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Broughton Sports Field or halfway across Broughton.

Stop when it is safe. Switch off. Leave the car off rather than testing it again.

More of that is pulled through with each start.

Broughton lies under 15 miles from the M27; if you were on it, exit by the next junction and stop somewhere safe instead of driving on.

Distance matters: each mile carries the AdBlue further into the system, and so heading towards Salisbury, under 15 miles away, gives a much larger job than hopping across Broughton to the car park by St. Mary's Church.

Approximately how far had it come? Tell us.

There is more to clean out once the motor has been started, and our engineers do all of it where your car has ended up.

Spotted soon, it very seldom leaves lasting damage.

## What clearing AdBlue from a diesel involves in Broughton

Anywhere it has come to rest in Broughton — a filling station, a lay-by, a drive, a street by Broughton Village Hall — our van comes to your car.

Three replies shape the job, so first we ask which fluid was put in, roughly the amount, plus if your engine has turned over.

The contaminated diesel and the urea come out as one after that tank is drained, right there.

A full flush matters much more with AdBlue than after petrol, because residue will not clear out by itself.

The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested.

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

Our equipment is explosion-proof, so a live forecourt is no issue, and it is quiet enough for a residential street after dark.

New diesel goes in to bleed your system, and that's the last step.

You drive off as soon as our engineers have started it, and it makes no difference whether the car is on a drive around Broughton or in a space by Mottisfont & Dunbridge.

Before we leave, we check it's running properly with clean diesel in.

No garage is needed at any point, with the entire job done on the spot.

You receive a VAT invoice and an engineer report after that, which is what insurers ask for.

## About Broughton, briefly

Broughton is a village situated in a riverside setting in Hampshire, with an elevation of 46 metres above sea level. Broughton lies near the cities of Salisbury and Winchester, and is surrounded by other small villages such as Bossington and Nether Wallop. Broughton has a population of approximately 1091 residents, who mostly live in detached houses. Broughton is located 68.2 miles from London, making it a rural retreat within commuting distance of the capital.

## AdBlue drains around Broughton and across Hampshire

AdBlue jobs in Broughton are passed to vans that cover the places around it — Bossington, Nether Wallop as well as Houghton — and most of Hampshire beyond, across SO postcodes.

Ring and ask instead of guessing if you're close to a border, or somewhere tricky to pin down.

A mobile service fits Broughton, a village: you have no need to bring your car to us, because we drain it there, on a drive, a side street, a parking area or a forecourt.

## What AdBlue in a diesel tank costs to put right in Broughton

Each job is different, so no single quote would be honest.

The cost shifts first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it depends on where the vehicle is and whether a technician can get to it safely, which is simpler on an open drive than in a tight spot behind Hildon House.

Ahead of a quote, not after, each enquiry from Broughton begins with the same three questions: the liquid, the amount, plus if the engine ran.

Once they are known, a range turns into one fixed number.

Our quote is given on the call, before anyone leaves; settling up comes on the day, by card or over the phone, with nothing upfront.

Misfuelling cover comes with many insurance policies, so it is worth looking at yours before the van arrives.

## Broughton: still next to your car?

Then, the best thing to do with your car is to not touch it.

Motor off, keys out, ignition off.

Petrol in Diesel takes over the remainder, in Broughton or anywhere in Hampshire, after you call 0333 366 0103 to say it's AdBlue, roughly how big an amount, and whether it ran.
