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

If AdBlue has gone into your diesel tank, leave the motor off then keep your ignition off.

Water with urea dissolved in it: that is AdBlue.

As it is water-based, it will not ignite and never combines with diesel; trouble only starts once the pump starts drawing it.

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

Phone 0333 366 0103 before you do anything else.

## Those opening minutes: AdBlue in the diesel tank around South Ashford

Do:

- Take your keys out, and so no one switches your ignition on.

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

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

- Give us a postcode starting TN23 7, or whichever street lies closest, and our van reaches you straight — so ring wherever you are.

Don't:

- No starting your engine — not for a second, not to reposition the car.

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

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

- Even a short way along Torrington Road is too far to drive it.

- No emptying it yourself, either, at the roadside.

Rolling the car away from the pumps is a job for attendants to help with, whichever South Ashford forecourt you're on, the BP included.

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

## AdBlue in a diesel tank, and what it does there

AdBlue is made for your exhaust, not the motor.

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

Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

Fuel mixes; AdBlue, once tipped in, will not. Its behaviour is nothing like diesel's.

It drops, because it is heavier than diesel, and settles low where the intake draws its fuel from.

A vehicle filled on a driveway in Brookfield yesterday evening and left unstarted counts as the simple one. No pump has pulled the AdBlue up so far — though when your engine turns, that's what is pulled first, straight from the bottom of your tank.

It causes two kinds of damage from there.

Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filters and narrow passages; and, because it attacks certain metals, each part it reaches suffers for as long as it remains in there.

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

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

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

Put petrol in a diesel at the eg and you have a fault of thin fuel.

No damage comes while it sits put, mixed into the diesel — only when the engine runs on it.

AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all.

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

Whether the car is in St Georges Square or the centre of South Ashford, firing it up "to see" costs more with AdBlue than almost any other error, and the flush matters for more. The reasons: it will not stay blended, and so diluting it fails; and crystals and corrosion survive the next tankful.

The same good news holds as with petrol.

If the motor hasn't run, the AdBlue is still in the tank, and your tank is the simplest part of a fuel system to clear, wherever in Kent the vehicle is standing.

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

It is not on purpose. Many cars keep the AdBlue inlet beside the diesel one, now and then behind a single flap, and mixing them up is easy in poor light.

Mostly it is never the forecourt: someone buys a bottle driving home and tips it in outside the house.

It tends to happen in a few familiar ways.

Midway through the drop-off, the dashboard warns, and outside Victoria Road Primary School the refill is rushed.

Near Christchurch Road, someone tips a bottle in at home in the evening.

Another pattern: dim light, a pub car park outside The Locomotive, and a driver using that flap for the first time.

The least familiar cars see it most — rentals, new ones, company cars, and the other vehicle of a home with one of each fuel types.

Wherever you are around South Ashford or the remainder of Kent, it is the same slip and the same first answer: leave the vehicle off.

## Started the engine with AdBlue in your diesel tank in South Ashford?

Then your tank is no longer where the AdBlue is.

The filter and pipework have had it pulled along, and some running time takes it on to the high-pressure pump and every injector.

Maybe coming back from Bowens Field, or part way across South Ashford, the engine might go rough, smoke, drop power, light up your dash or cut out.

When safe, pull over and turn it off — with no turning it on again to see.

More of it is pulled through with each start.

Leave the M20, under 3 miles from South Ashford, at the next junction and park somewhere safe, rather than driving on.

Each mile pushes the AdBlue deeper into your system. That's why a hop across South Ashford to park beside Christ Church and a drive of under 15 miles for Canterbury are such different jobs.

Roughly how far it had come is worth telling us.

Once your engine has run, the flush takes in more, and all of it is done where your car has come to a stop.

Noticed quickly, it very seldom leaves long-term damage.

## Clearing AdBlue in a diesel in South Ashford: what it takes

The vehicle stays where it is, whether that's a street near Evangelical Church, a driveway, a lay-by or a filling station around South Ashford, and our van travels to it.

The job rests on three answers, which we get before all else — which fluid was put in, the amount, and if the motor has turned over.

On the spot, that tank is then drained, and all of the contaminated diesel and the urea leave as one.

A careful flush matters much more after AdBlue than after petrol, because what remains won't clear away on its own.

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

Roughly half an hour once we arrive is typical for most jobs when your engine has not run.

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

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

At that point our engineers fire it up and you drive off, whether from a parking space by Ashford International or a driveway in South Ashford.

It's tested on clean diesel to be sure it runs smoothly before we head off.

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

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

Assuming won't help by a county line or somewhere tricky to describe; ring and ask.

## AdBlue in a diesel tank in South Ashford: the cost of fixing it

Because each jobs vary, a single figure wouldn't be honest.

Whether the engine has run, and for how long, comes first in what moves the price. How much AdBlue went in comes next, and then the location of the car, because an open driveway is simpler for our van to reach safely than a tight spot behind M&S Outlet.

That's why each call from South Ashford starts with the same three queries, asked before giving a figure, not after: what was put in, how much, and if it's run.

The replies turn a range into a straight price.

Before anyone sets off, you hear our price on the phone. Then payment is on the day, 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 gets there.

## Still beside the vehicle around South Ashford?

Not touching the car is, then, the most useful move open to you.

Motor off, keys out, ignition off.

Petrol in Diesel takes over the remainder, in South Ashford or wherever in Kent, after you phone 0333 366 0103 to say it was AdBlue, about what quantity, and whether it ran.
