# AdBlue in a Diesel Tank in Kingswood? Don't Start It

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

In plain terms, AdBlue is just urea in water.

The harm begins once it is sucked through the pump — it won't burn, and it won't blend with diesel.

If the engine hasn't run yet, AdBlue in a diesel tank is generally drained and thoroughly flushed where your car sits around Kingswood.

Ring 0333 366 0103 before you do anything else.

## What to do straight away, Kingswood: AdBlue in your diesel tank

Do:

- So no one can turn the ignition on, take your keys out.

- Hazards on, if moving traffic is at all near.

- Which fluid, and about what quantity? Save the bottle or the till receipt, and our technicians will see.

- Tell us a postcode starting SS16 5, or whatever street lies closest, and the van finds you straight — so ring wherever you are.

Things not to do:

- Not even briefly, and not to shift your vehicle: the motor stays off.

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

- AdBlue does not mix in diesel — it separates out — so adding more fuel will not weaken it.

- Even a short distance along Wynters is too far to drive it.

- Emptying your tank yourself by the road isn't worth trying.

Ask the people behind the counter to help you roll the vehicle away from the pumps if you're on a forecourt in Kingswood, whether it's the Asda or somewhere else.

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

## AdBlue in a diesel tank: what it does

The engine is not what AdBlue is made for; your exhaust is.

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

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

Tipped in with the diesel, it keeps separate rather than mixing — entirely different from fuel.

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

A motor topped up on a drive in Lee Chapel overnight and not started since is the simple case. No pump has pulled the AdBlue up so far — but once the engine runs, that is what goes first, directly from the bottom of the tank.

From there it does two kinds of harm.

Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filter elements and narrow channels; and, because it eats at some metals, every part it reaches keeps suffering for as long as it remains in there.

A motor left standing in Kingswood with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't.

Then there is the water: it brings no protection to the components that rely on it the most — the high-pressure pump and each injector.

## Why AdBlue in a diesel is regularly more major than petrol

Top up a diesel with petrol in error at the BP, and the problem is thinned fuel.

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

AdBlue in a diesel is another matter: not thin fuel, yet no fuel at all.

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

Crystals and corrosion remain through the following tankful, and AdBlue splits again out of the diesel, and so thinning it can't work. Hence the flush matters so much, and turning your key "to see" costs more here than nearly any other mistake — in Barstable or the heart of Kingswood alike.

The same good news holds as with petrol.

Wherever around Essex your vehicle has come to rest, an unrun engine means the AdBlue still inside the reservoir: the simplest part of a fuel system to clear.

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

It's not deliberate. Plenty of cars have the AdBlue inlet beside the diesel one, now and then under a single flap, and mixing them up is easy after dark.

Mostly it is never the forecourt: a driver picks up a bottle heading home and pours it in at home.

The ways it occurs are few and familiar.

Rushing, outside Kingswood Primary School and Nursery, after a warning light flashed on during the school run, someone tops up your car.

Near Sparrows Herne, a driver tips a container in on that drive after work.

Else, after dark by The Owl and The Pussycat, the car is refilled by a driver opening that flap for the first time.

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

Anywhere across Essex, Kingswood included, the mistake doesn't change, and nor does the first step: keep it switched off.

## Already started your engine with AdBlue in your diesel tank around Kingswood?

Then that tank is no longer where the AdBlue is.

It's been pulled through the fuel filter and the fuel lines, and if your motor ran for any time, it has reached the high-pressure fuel pump and your injectors.

You may see the engine running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Clicket Hill Playground or halfway across Kingswood.

No restarting to test: pull over when safe, then turn everything off.

Every start pulls more of that through.

Exit the M25, under 10 miles from Kingswood, at the next junction and park safely, not carrying on.

A quick hop across Kingswood to the car park by Kingswood Community Centre is one matter; heading for Southend-on-Sea, under 15 miles away, is something else, because every mile carries the AdBlue deeper in. So mileage counts.

Tell us about how far it had come.

There's more to rinse out once the engine has run, and our engineers do all of it where the vehicle has stopped.

Very rarely does it leave permanent damage if it is spotted soon.

## What does an AdBlue drain on a diesel involve in Kingswood?

We come to your car, wherever it has stopped in Kingswood: a side street near Kingswood Baptist Church, a drive, a lay-by or a forecourt.

The job rests on three replies, which we get first — which fluid was put in, the amount, and whether the engine has run.

Right there, that tank is then drained, and all of the contaminated diesel and the urea leave at once.

The fuel system is flushed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind does not rinse out on its own.

A test of the vehicle comes at the end, after fresh diesel is added and the fuel filter is cleaned or, if necessary, swapped.

If your engine hasn't run, the majority of jobs take about half an hour once our technicians are there.

The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.

Priming your system with new diesel comes last.

You set off as soon as our engineers have fired it up, and it makes no difference whether your car is on a driveway in Kingswood or in a bay at Basildon.

It is checked on new diesel to make sure it runs correctly before we head off.

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

Your insurer is likely to want an engineer's report and your VAT invoice — each handed over once the job is done.

## About Kingswood and where it is

Kingswood is a suburban area in Essex, situated approximately 25.7 miles from London and 10.8 miles from Southend-on-Sea. Kingswood sits at an elevation of around 35 metres, in a location near to Basildon, Ghyllgrove, and Lee Chapel South. Kingswood has a population of around 6048 people, predominantly living in terraced housing. Kingswood forms a residential community within the wider Southend-on-Sea urban area.

## Kingswood and Essex: AdBlue drains across the area

Our vans that answer AdBlue call-outs in Kingswood also cover the places about it, Basildon, Ghyllgrove and Lee Chapel South among them, and most of Essex beyond, across the SS postcode area.

Phone and check instead of guessing when you are by a county line, or anywhere awkward to pin down.

Kingswood is a residential suburb, and a mobile drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it sits, so it never needs to be moved to us.

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

There is no fair single quote, since the jobs aren't the same.

Three things shift the price: whether your engine has been running and for how long, how much AdBlue went in, and where your car is. That last one rests on whether our van can get to it safely, and an open driveway is simpler than a tight space behind Eastgate Shopping Centre.

With that in mind, every call from Kingswood begins with the same trio — what was put in, how much, if the engine ran — before a figure.

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

You get that price on the phone, before anyone sets off, and you pay on the day, by card or by phone, with nothing upfront.

Check your insurance whilst we are on the way: plenty include misfuelling cover.

## In Kingswood and still next to your car?

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

Ignition off, engine off, keys out.

Petrol in Diesel takes over the remainder, across Kingswood or wherever within Essex, once you ring 0333 366 0103 saying it's AdBlue, about how big an amount, and whether the engine ran.
