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

AdBlue in the diesel tank? Then leave your engine off — and the ignition too.

In plain terms, AdBlue is just urea in water.

Not like fuel, it neither ignites nor mixes, and no harm starts till the engine pulls it through.

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

Before you do anything else, call 0333 366 0103.

## Kenilworth, AdBlue in your diesel tank: what to do at once

Do these:

- Keys out — then no one can power anything on.

- If you're at all near moving traffic, put your hazards on.

- Hold on to your receipt or the empty bottle, so you can tell us what got in and about how much.

- Call right where you are. Quote a CV8 1 postcode or the closest street sign, and nobody has to hunt for you.

Not to do:

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

- Turning the key to ignition by itself starts the pump running on many diesels. Skip it.

- Pouring in more diesel doesn't help: AdBlue separates out instead of blending.

- Even a short way up Warwick Road is too far to drive the car.

- No emptying it yourself, at all, on the verge.

Ask the attendants to help you move your car away from the pumps if you are at a forecourt in Kenilworth, whether it's the Esso or elsewhere.

On that drive, the car remains just where it was left.

## What AdBlue does in a diesel tank

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

Its own tank keeps it, and from there it's fed into your exhaust, and there it treats the fumes.

Not one side suits the other: urea doesn't belong in an injection pump, and a pump cannot take urea.

Poured in with your diesel, it keeps apart instead of blending — quite different from fuel.

It is heavier than diesel, and so it sinks and gathers at the bottom of your tank, which is where the pickup draws fuel from.

The first thing your fuel system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in St Johns last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.

It causes two kinds of damage from there.

It attacks certain metals found in fuel systems, attacking whatever it reaches until it's removed from the system. And once the water evaporates, the urea forms crystals that block filters and lodge in tiny passages.

Lines holding AdBlue mean harm by morning for a car parked around Kenilworth. Only in your tank, it stays the same.

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

## Why is AdBlue in a diesel regularly the bigger issue?

Put petrol in a diesel at the Texaco and you have an issue of thin fuel.

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

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

Because it doesn't burn, running it through isn't an option.

Whether the vehicle sits in Whitemoor or the centre of Kenilworth, turning it over "to see" does more harm with AdBlue than almost any other mistake, and the flush matters more. The reasons: it will not stay blended, and so diluting it fails; and crystals and corrosion survive the following tankful.

The good news is the same as with petrol.

If your engine hasn't run, the AdBlue is still inside that tank, and the tank is the simplest part of a fuel system to clear, wherever across Warwickshire your car is standing.

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

Plenty of motors put the AdBlue filler beside the diesel one, occasionally under one flap, and in dim light the two may appear identical. Nobody intends it.

It usually happens outside the house, from a bottle grabbed on the journey home, not at the forecourt.

A few familiar ways account for most cases.

Hurrying, outside St Nicholas CofE Primary School, after a warning lamp flashed on during the school run, someone tops up the vehicle.

A bottle is poured in at the end of the day on a drive just off Custard Corner.

Or someone unfamiliar with that flap tops up your vehicle in dim light, stopped in the car park by The Dictum of Kenilworth.

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

Wherever you are around Kenilworth or the rest of Warwickshire, it is the same slip and the same first answer: leave it off.

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

Then the AdBlue has left that tank.

Given any running time, it goes on to the high-pressure pump and each injector, having passed through the filter and pipework.

Maybe coming back from Abbey Fields, or part way across Kenilworth, your engine might go lumpy, smoke, drop pace, light up your dash or cut out.

Once you safely can, stop then switch it off — without turning it on again to see.

Each start pulls more of it through.

On the M40, under 10 miles from Kenilworth, the next junction is where to leave, and somewhere safe is where to stop — not carrying on.

Distance matters: every mile pushes the AdBlue further in, and so driving for Coventry, under 10 miles away, makes a much larger job than hopping across Kenilworth to the car park by Kenilworth Clock Tower.

About how far it had come is worth telling us.

There is more to rinse out once the engine has been run, and we do all of it where the car has stopped.

Very seldom does it leave lasting damage when it is spotted early.

## Clearing AdBlue in a diesel around Kenilworth: what it takes

Our technicians come to the vehicle, wherever it has stopped in Kenilworth: a side street close to Kenilworth Library, a drive, a lay-by or a forecourt.

Before anything else our technicians ask what went in, about how much, and whether your engine has run, because those replies determine the work.

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

Your system is purged thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own.

Testing your vehicle follows last, after clean diesel goes in and your filter gets flushed or, where needed, replaced.

The majority of these jobs are a half-hour job once our technicians turn up, if your motor hasn't run.

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

Priming the fuel system with clean diesel comes at the end.

Whether it's a parking space at the nearest station or a drive around Kenilworth, that is where our technicians fire it up and you drive off.

Before we go, our engineers make sure it's running smoothly with fresh diesel in.

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

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

## AdBlue drains across Warwickshire, Kenilworth included

Abbey End, Abbey Fields and Borrowell are among the towns around Kenilworth that the same vans serve, together with most of Warwickshire further out, over the CV postcode area.

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

Kenilworth is a riverside town, and a call-out drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, we drain it where it stands, so it never needs to be moved to us.

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

Not one flat figure would be fair, since each job differs.

Whether your engine has run, and for how long, comes first in what changes the price. How much AdBlue was put in comes next, and then the location of your car, since an open driveway is easier for a van to get to safely than a tight spot behind Millennium Globe.

Ahead of any quote, never after, every call from Kenilworth opens with three questions: the liquid, the quantity, and whether the engine ran.

The answers turn a range into a straight price.

The quote is given during the call, before a van leaves; settling up comes on the day, by card or over the phone, with nothing upfront.

Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way.

## Still alongside the car in Kenilworth?

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

Ignition off, motor off, keys out.

Call 0333 366 0103 then tell us it's AdBlue, about how much, and if it has run. Petrol in Diesel takes it from there, in Kenilworth or anywhere around Warwickshire.
