# Don't Start It: AdBlue in a Diesel Tank in Dudleston Heath

Motor off, ignition off: that is how you start if AdBlue has got into your diesel tank.

Urea mixed in water is what AdBlue is.

Unlike fuel, it neither ignites nor blends, and nothing happens till your engine pulls it round.

A drain and a thorough flush, done where the vehicle is in Dudleston Heath, is usually all AdBlue in a diesel tank needs — if it is caught before your engine has run.

First, call us on 0333 366 0103.

## Your next steps straight away, Dudleston Heath: AdBlue in the diesel tank

Do:

- Keys out — that way nobody can switch anything on.

- Close to moving traffic? So put the hazards on.

- Which fluid, and roughly how much amount? Hang on to the bottle or your receipt, and our technicians can know.

- Give us a postcode starting SY12 9, or whichever street lies nearest, and the van finds you straight — so call wherever you stand.

Don't do these:

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

- Your ignition remains off: on lots of diesels, switching it on is enough to run the fuel pump.

- Don't top up with diesel to dilute it. AdBlue doesn't mix in diesel; it separates out.

- Keep the vehicle where it is instead of driving it anywhere, even a short distance along Hill Park.

- Do not try to drain the car yourself at the kerbside.

Moving your vehicle away from the pumps is a job for staff to help with, whichever Dudleston Heath forecourt you are on, the Texaco included.

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

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

The engine isn't what AdBlue is made for; the 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.

Inside a diesel tank it behaves very differently from fuel. It doesn't mix in.

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.

Simplest of all: a vehicle that had AdBlue in Greenhill Bank overnight and has not turned since. The liquid waits at the base of the tank, untouched — though it would be first through once your engine runs, before any diesel at all.

From there it causes two kinds of damage.

What is left when the water evaporates is urea, which turns into crystals: they lodge in tiny channels and clog filters. Worse, it eats at certain metals in the fuel system, and keeps going till it is flushed out.

Lines carrying AdBlue mean harm by morning for a vehicle sitting in Dudleston Heath. Only in your tank, it stays stable.

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

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

A fault of thinned fuel is what you get after filling a diesel with petrol at the BP.

Harm just comes from driving on it. Mixed into the diesel and left inside the tank, it does none.

AdBlue in a diesel is another problem: not thin fuel, but no fuel at all.

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

Crystals and corrosion stay through the following fill, and AdBlue splits again from your diesel, so watering it won't work. That is why the flush matters so much, and trying your engine "to see" does more harm with AdBlue than nearly any other slip — in Bryn-y-cochin or the centre of Dudleston Heath alike.

With AdBlue, the good news is no different from petrol.

Not started? Then the AdBlue sits only inside the tank, the simplest bit of the whole system to empty, wherever your vehicle has come to rest around Shropshire.

## Dudleston Heath: how AdBlue ends up in a diesel tank

It's not deliberate. Many cars have the AdBlue inlet beside the diesel one, now and then under a single flap, and mixing them up is easy in poor light.

Most of the time it takes place with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

The ways it happens are few and familiar.

Rushing, outside Criftins CofE Primary School and Nursery, after a warning light came on during the school run, a parent refills the car.

A bottle is poured in at the end of the day on a drive just off B5068.

Or a driver new to that flap tops up the car after dark, stopped in the car park outside the pub in the village.

It takes place most in the motors people 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 around Shropshire, Dudleston Heath as well, the slip does not change, and nor does the first step: leave it switched off.

## AdBlue in the diesel tank around Dudleston Heath, and the motor started?

Then that tank is no longer where the AdBlue is.

Via the fuel filter, along the pipework, and — given any running — on to the high-pressure pump and every injector: that is how far it travels.

You may see your engine running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Groves Wood or halfway across Dudleston Heath.

Stop as soon as it is safe, switch off, and don't restart the car to check.

More of that is pulled through with each start.

Dudleston Heath lies under 25 miles from the M53; if you were on it, leave at the next junction and pull up safely instead of carrying on.

Distance matters: each mile pushes the AdBlue further into your system, so heading for Wrexham, under 10 miles away, gives a much bigger job than crossing Dudleston Heath to the car park by Criftins Parish Hall.

Approximately how far had it come? Tell us.

Our technicians do all of the rinsing where the vehicle has ended up, and once the motor has been started there is more of it.

If it is caught quickly, lasting damage is very unusual.

## Dudleston Heath: how AdBlue is drained from a diesel

A street beside St Matthew, a drive, a lay-by or a filling station: wherever your vehicle has come to rest around Dudleston Heath, our engineers come to it.

The job rests on three replies, and our technicians get before all else — which fluid got in, the quantity, and whether your engine has run.

Next, draining the tank right there takes out the polluted diesel along with the AdBlue in one go.

The system is flushed thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own.

Next, your filter: flushed, or replaced when it has to be. After that clean diesel, then a check of your car.

If your motor has not run, most jobs take about half an hour once we are there.

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

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

Whether it is a parking bay at Gobowen or a driveway in Dudleston Heath, that is where our technicians start it and you set off.

Our engineers confirm it runs smoothly on clean diesel before we go.

The entire job is done where your car is, so it never has to go to a garage.

Insurers ask for a VAT invoice and an engineer report, and you get both afterwards.

Close to a boundary, or anywhere tricky to explain? Checking is better than guessing, so ring.

## What does AdBlue in a diesel tank cost to sort out in Dudleston Heath?

Not one single figure could be honest, because each job differs.

Whether the motor has run, and for how long, comes first in what moves the price. How much AdBlue got in comes next, and then the position of the car, since an open driveway is simpler for a technician to reach safely than a tight space behind St Mary the Virgin.

What was put in, how much, plus if it ran: each Dudleston Heath enquiry begins with exactly that, ahead of a figure, never after.

Their answers shrink the range down to a single number.

Priced on the call before the van sets out, the job is settled on the day — card or phone, nothing in advance.

As our engineer is on the way, check your insurance: plenty cover misfuelling.

## Dudleston Heath: still beside your car?

Then, do nothing — that is the best step there is.

Keys out, engine off, ignition off.

Say it's AdBlue, roughly how big an amount, and whether the engine ran, on 0333 366 0103. After that Petrol in Diesel takes over, across Dudleston Heath or wherever within Shropshire.
