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

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

AdBlue is urea dissolved in water.

Unlike fuel, it neither burns nor mixes, and nothing starts till the motor sucks it round.

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

Before you do anything else, phone 0333 366 0103.

## Stockingford, AdBlue in your diesel tank: what to do right away

Do these:

- Remove your keys, and that prevents someone switching the electrics on.

- Near moving traffic? So put the hazards on.

- So you can tell us which fluid it was and about what quantity, save the receipt or the empty bottle.

- Ring right where you are. Say a CV10 8 postcode or the nearest street name, and no one has to hunt for you.

Don't:

- Do not start the engine, even for a moment to shift the vehicle.

- Plenty of diesels power their fuel pump the moment the ignition goes on, so keep the car off.

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

- Keep the vehicle where it is instead of driving it anywhere, even a short stretch down Wiclif Way.

- Draining the tank on your own by the road isn't one to try.

On a forecourt in Stockingford, whether it's the the nearest petrol station or another one, ask the attendants to help you push your car clear of the petrol pump.

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

## What does AdBlue do in a diesel tank?

AdBlue is made for the exhaust, not your engine.

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

A fuel pump is not designed to cope with it, and AdBlue was never intended to go through one.

Fuel blends; AdBlue, after poured in, will not. Its behaviour is not at all like diesel's.

It drops, since it is denser than diesel, and pools down where the intake draws its supply from.

Easiest of all: one that had AdBlue in Galley Common last night and has not been started since. The liquid sits at the foot of your tank, undrawn — but it will be the first thing through if the motor starts, before any diesel at all.

After it's drawn in, the harm comes in two forms.

It attacks some metals found in fuel systems, working on any part it reaches until it is cleared from your system. And once the water evaporates, the urea forms crystals that clog filters and settle in tiny passages.

Where the AdBlue is in the lines, waiting overnight around Stockingford leaves it worse. Inside that tank only, waiting does nothing.

Then there is the water: it offers no protection to the components that rely on it most — the injection pump and each injector.

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

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

No damage is done while it sits unused, blended into the diesel — only when the motor runs on it.

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

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

It doesn't stay mixed, so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting the motor "to see" costs more here than almost anywhere else, whether the car is in Heath End or the middle of Stockingford.

The same good news holds as with petrol.

Clearing a tank is the simplest part on a fuel system, and without running, the AdBlue remains in there — anywhere around Warwickshire your vehicle sits.

## How does AdBlue end up in a diesel tank in Stockingford?

It is not deliberate. Plenty of cars have the AdBlue cap beside the diesel one, occasionally behind one flap, and mixing them up is easy in poor light.

Usually it is not the forecourt: a driver buys a bottle heading home and tips it in at home.

The ways it occurs are few and familiar.

A warning light comes on during the school run, and the top-up takes place in a hurry outside St Paul's CofE Primary School, Nuneaton.

After work, a container goes in on a drive near St Paul's Road.

Else, after dark by The Royal Oak, your vehicle gets topped up by someone opening that flap the first time.

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

Leave it off: that is the first response to an identical mistake, wherever in Stockingford or the remainder of Warwickshire you happen to be.

## AdBlue in the diesel tank in Stockingford, and the engine started?

In that case, the AdBlue is no longer in the tank.

Given any running time, it travels to the high-pressure pump and each injector, after passing via your filter and lines.

You may notice the engine running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Stockingford Recreation or halfway across Stockingford.

Once you safely can, stop and turn everything off — with no turning it on again to test.

More of it is pulled through with each start.

Exit the M6, under 5 miles from Stockingford, by the first junction and stop safely, not driving on.

How far it went counts. A couple of hundred yards across Stockingford to the car park by St. Paul is a very different job from a run towards Coventry, under 10 miles away, with the AdBlue reaching further into the fuel system with each mile.

Let us know roughly how far it had come.

Our technicians do all of the cleaning where the vehicle has come to a stop, and once the engine has been started there is more of it.

When it's noticed early, lasting damage is very rare.

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

Wherever it has stopped in Stockingford — a forecourt, a layby, a drive, a street by Stockingford Community Centre — the van comes to your vehicle.

Three answers shape the work, and so first our engineers ask which fluid got in, about the amount, and whether your motor has run.

On the spot, the tank is then drained, and both the contaminated diesel and the urea come out as one.

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

After that, the filter: cleaned, or replaced when it must be. After that clean diesel, and then a check of the car.

Engine not run? Then expect about half an hour once we are there for most jobs.

The equipment is explosion-proof, so a busy filling station is no problem, and it's hushed enough for a residential street after dark.

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

At that point our engineers start the car and you drive off, whether from a parking bay by Bermuda Park or a drive in Stockingford.

Our engineers make sure it runs properly on fresh diesel before we go.

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

At the end, you are given the paperwork for the insurer: a VAT invoice and a report from the engineer.

## About Stockingford

Stockingford is a suburban area in Warwickshire, situated on the riverside at an elevation of 131 metres, with terraced housing being the predominant type of accommodation. Stockingford lies approximately 7.7 miles from Coventry and 91.3 miles from London, making it a commuter-friendly location. Stockingford is surrounded by nearby places such as Whittleford, Camp Hill, and Robinsons End, and has a population of around 6850 residents. Stockingford's riverside setting provides a unique character to the area.

## AdBlue drains across Warwickshire, Stockingford included

Whittleford, Camp Hill and Robinsons End are among the towns around Stockingford that the same vans reach, together with much of Warwickshire further out, over the CV postcode area.

Assuming won't help close to a border or somewhere hard to describe; ring and check.

No towing is needed. In Stockingford, a residential suburb, a mobile service fits: the car is drained where it stands, be it on a drive, a residential street, a car park or a filling station.

## AdBlue in a diesel tank around Stockingford: the cost of fixing it

Because the jobs vary, a flat price wouldn't be fair.

Three things change the price: whether the motor has run and for how long, how much AdBlue was put in, and where the car is. That last one comes down to whether a van can get to it safely, and an open drive is simpler than a tight gap behind Welcome to Grove Farm.

What was put in, how much, plus whether the engine ran: every Stockingford enquiry begins by asking exactly that, before a quote, never afterwards.

Those replies shrink a range down to a single figure.

Before anyone heads out, you hear our price on the phone. Then payment is on the day, card or by phone, with nothing upfront.

While our engineer is travelling, check your policy: many cover misfuelling.

## Stockingford: still alongside the vehicle?

Leaving your vehicle alone is, then, the most useful thing open to you.

Keys out; engine and ignition off.

Call 0333 366 0103 then tell us it is AdBlue, roughly how much, and whether it's run. Petrol in Diesel takes it from there, in Stockingford or anywhere in Warwickshire.
