# AdBlue in the Diesel Tank in Bonnington? Keep It Switched Off

If AdBlue has got into the diesel tank, keep your engine off and keep the ignition off.

Urea dissolved in water is all AdBlue is.

The trouble starts once it's sucked through your pump — it won't ignite, and it won't combine with diesel.

A drain and a thorough flush, done where your car is in Bonnington, is generally all AdBlue in a diesel tank takes — if it is caught before your engine has been run.

First, phone us on 0333 366 0103.

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

Do these:

- Pocket the keys, and that stops someone switching the power on.

- Put the hazards on if you're at all close to moving traffic.

- So you can tell us which liquid it was and roughly how much, keep your receipt or the empty bottle.

- Ring us from where you are. A postcode starting TN25 7, or the name of the closest street, gets the van to you without a search.

Things not to do:

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

- Switching your key to ignition alone starts your pump going on plenty of diesels. Avoid it.

- AdBlue doesn't mix in diesel — it separates out — so adding extra diesel will not weaken it.

- Leave the car where it is rather than driving it anywhere, even a short distance down Bourne Road.

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

Get the attendants to help you roll the car away from the island if you're at a forecourt around Bonnington, whether it's the John Childs Garages or elsewhere.

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

## What AdBlue does in a diesel tank

Not the motor but the exhaust is where AdBlue is meant to go.

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

No part in a fuel pump is designed for this liquid — and no part of that was intended to travel that way.

Inside a diesel tank it behaves very differently from fuel. It does not mix in.

The intake takes fuel from the lowest part of that tank, and that is just where AdBlue settles: being heavier than diesel, it sinks.

A motor topped up on a driveway in Bilsington yesterday evening and not started since is the straightforward one. Nothing has pulled the AdBlue up so far — but when the engine turns, that's what is pulled first, straight from the bottom of the tank.

It causes two kinds of damage from there.

What is left when the water evaporates is urea, which forms crystals: they settle in narrow channels and block filters. On top of that, it attacks some metals in a fuel system, and carries on until it is flushed out.

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

And there's the water: it brings no lubrication to the parts that rely on it most — the injection pump and every injector.

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

An issue of thin fuel is what you get after filling a diesel with petrol at the Tesco.

No damage is done while it sits unused, blended into your diesel — only once the engine works on it.

The trouble with AdBlue in a diesel is a completely unsuitable liquid.

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

Whether the car is in Chequertree or the centre of Bonnington, firing it up "to see" does more harm in this case than almost any other mistake, and the flush counts for more. Why: it will not remain mixed, so diluting it fails; and deposits and corrosion outlast the next fill.

The same good news holds as with petrol.

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

## How AdBlue ends up in a diesel tank around Bonnington

No one 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.

A bottle picked up when heading home and tipped in at home, rather than at the filling station, is the typical story.

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

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

Near Cherry Orchard Lane, a driver pours a container in at home in the evening.

Or the vehicle is topped up in the car park at Walnut Tree Inn, in poor light, by somebody who has never opened that flap before.

It takes place most in the motors people know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol.

An identical mistake, same first response — leave it off — anywhere you happen to be around Bonnington or the remainder of Kent.

## Already started the engine with AdBlue in the diesel tank around Bonnington?

The AdBlue has left that tank, then.

With any running, it travels to the high-pressure pump and every injector, having passed through your filter and pipework.

Perhaps coming back from Park Wood, or part way across Bonnington, your engine may run lumpy, smoke, drop power, light up your dash or cut out.

No starting it again to check: pull over when safe, then turn it off.

Every start pulls more of that through.

Bonnington sits under 3 miles from the M20; if you were on it, leave by the next junction and stop safely rather than driving on.

Each mile carries the AdBlue deeper in. That is why a hop across Bonnington to park near Aldington Village Hall and a drive of under 25 miles towards Canterbury are very distinct jobs.

Roughly how far had it come? Tell us.

There is more to rinse out once the motor has been started, and our engineers do all of it where the vehicle has stopped.

If it is caught soon, long-term damage is very uncommon.

## What emptying AdBlue from a diesel involves around Bonnington

Wherever it has stopped around Bonnington — a forecourt, a layby, a driveway, a road by Saint Rumwold's Church — the van travels to your car.

The job depends on three answers, and we ask for first — what got in, the quantity, and if the motor has turned over.

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

A careful flush matters much more with AdBlue than with petrol, because residue won't clear away by itself.

Fresh diesel goes in after the filter is cleaned — or replaced, if it needs to be — and after that the car is tested.

Most of these jobs are a half-hour job once our engineers arrive, provided the motor has not run.

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

Finally, the system is primed with clean diesel.

Starting the engine comes next, and then you drive off from where your car is parked, outside Ham Street or on a drive around Bonnington.

It is checked on fresh diesel to make sure it runs properly before our engineers go.

No workshop is required at any point, with the entire job done then and there.

Insurers want a VAT invoice and an engineer report, and you get both at the end.

## About Bonnington itself

Bonnington is a small village in Kent, situated inland at an elevation of 34 metres, approximately 15 miles from Canterbury and 54 miles from London. Bonnington is characterised by its predominantly detached housing stock, reflecting its rural setting. Bonnington lies near other small settlements, including Aldington and Aldington Frith, and is surrounded by the countryside of the South East region.

## Bonnington and Kent: AdBlue drains across the area

Throughout the TN postcode area, the vans answering AdBlue jobs around Bonnington reach much of Kent as well, Aldington, Aldington Frith and Clap Hill included.

Close to a border, or anywhere tricky to explain? Asking beats assuming, so ring.

Wherever the vehicle stands — your driveway at home, a residential street, a parking area, a filling station — we empty it on the spot, and there's no need to take it to us; which suits Bonnington, a rural village, well.

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

Each job is different, and so no fixed price would be honest.

The price moves first with how long, if at all, the motor has been running, and next with the amount of AdBlue that went 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 St Peter & St Paul.

Ahead of any quote, not after, each enquiry from Bonnington begins with the same three checks: the liquid, the quantity, plus whether the engine ran.

When those are answered, a range becomes a single firm number.

Our quote is quoted during the call, before anyone leaves; settling up happens on the day, by card or over the phone, and nothing upfront.

As the van is travelling, dig out your policy: many include misfuelling.

## In Bonnington and still next to the car?

In that case, touch nothing — that is the most helpful move there is.

Engine off, keys out, ignition off.

Ring 0333 366 0103: AdBlue, roughly how much, plus whether it ran is everything our engineers need. Petrol in Diesel takes over the remainder across Kent, Bonnington too.
