# Woodnook: AdBlue in the Diesel Tank? Leave It Off

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

Water with urea mixed in it: that is AdBlue.

As it is water-based, it won't burn and never combines with diesel; trouble just comes once the pump begins drawing it.

In Woodnook, AdBlue in a diesel tank caught before your engine runs normally comes down to a drain and a thorough flush, right where your car is.

Before you do anything else, ring 0333 366 0103.

## AdBlue in your diesel tank in Woodnook: the first few minutes

Do:

- Pocket the keys, which prevents anyone turning the power on.

- Near moving traffic? So put your hazards on.

- So you can give us which liquid it was and about how much, save the till receipt or the empty bottle.

- Our van finds you quickest with a postcode starting BB5 2, or simply the name of a street nearby, so phone from the car.

Things not to do:

- No starting the motor — not briefly, not to reposition the car.

- Many diesels power their pump the instant your ignition comes on, and so keep the car off.

- Do not top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.

- Any driving at all is to be avoided, including a short distance along Spindle Berry Court.

- Beside the road, do not try emptying it on your own.

At a forecourt in Woodnook, whether it's the Esso or another one, ask the attendants to help you push the car away from the pump.

Stopped on your own driveway? Then it stays exactly where it is.

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

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

Stored in a separate tank, it is squirted into the exhaust stream to clean the gases.

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

It does not blend. Once it's poured into a tank of diesel, AdBlue behaves not at all like fuel.

It drops, because it's denser than diesel, and settles low where the intake takes its fuel from.

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

Two kinds of damage come from there.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps working on the components it reaches for as long as it stays there.

Where the AdBlue is in the lines, leaving it till morning around Woodnook leaves things worse. Inside your tank alone, time costs nothing.

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

## Petrol or AdBlue in a diesel: why AdBlue is regularly worse

Petrol pumped into a diesel on Texaco's forecourt leaves the fuel watery — that is the main issue.

Blended through the diesel and sitting still, it is no threat for now; running your motor is the damage.

AdBlue in a diesel is a fault of the wrong substance altogether.

Not burning, it can't simply be run through.

Nor can it be watered down, because it splits again — and the following fill won't rinse away crystals or corrosion. So the flush matters more with AdBlue, and trying the engine "to see", in the heart of Woodnook or out in Lower Fold, costs more than almost any other mistake.

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

Anywhere around Lancashire the vehicle has stopped, an unstarted engine means the AdBlue yet inside the tank: the easiest bit of any fuel system to empty.

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

Many motors put the AdBlue filler beside the diesel cap, now and then behind a single flap, and in dim light the two may look identical. No one intends it.

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

The ways it happens are few and familiar.

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

After work, a container goes in on a driveway close to Belfield Road.

Or a driver new to that flap refills the vehicle after dark, stopped in the car park by The Park.

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

An identical slip, same first response — leave it off — anywhere you are around Woodnook or the rest of Lancashire.

## Already started the motor with AdBlue in the diesel tank around Woodnook?

Then that tank is no longer where the AdBlue is.

Your filter and lines have had it sucked along, and any running carries it on to the high-pressure pump and every injector.

Watch for rough running, smoke, falling power, warnings on the dash, or a cut-out — coming back from Oak Hill Park, say, or part way across Woodnook.

No restarting to check: pull over when it is safe, then switch everything off.

Each start pulls more of it through.

On the M65, under 3 miles from Woodnook, the next junction is where to exit, and somewhere sensible is where to park — not driving on.

Hopping across Woodnook to the car park by Trinity Community Church is one thing; driving for Preston, under 15 miles away, is something else, because each mile pushes the AdBlue further in. So distance counts.

Tell us about how far it had come.

There's more to clean out once your engine has been run, and our engineers do all of it where the vehicle has ended up.

Long-term damage is very unusual if it is noticed early.

## What emptying AdBlue from a diesel involves in Woodnook

A street by St James, Accrington, a driveway, a lay-by or a forecourt: anywhere your vehicle has stopped around Woodnook, our technicians come to it.

Three replies decide the work, and so first our technicians ask what was put in, roughly the amount, plus whether your engine has run.

Next, draining the tank right there removes the polluted diesel and the AdBlue in one go.

Residue from AdBlue won't flush out by itself, so the fuel system gets a careful flush, which counts much more with urea than with petrol.

A test of the vehicle follows at the end, after fresh diesel goes in and the filter gets cleaned or, if needed, swapped.

If your engine has not run, the majority of jobs take about half an hour once our engineers are there.

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

The last step is to prime the system on clean diesel.

Whether it's a parking space outside Accrington or a drive around Woodnook, that is where we fire it up and you set off.

It's tested on clean diesel to make sure it runs correctly before we go.

No garage is needed at any point, with the entire job done on the spot.

You get a VAT invoice and an engineer report after that, which is what insurers ask for.

## AdBlue drains across Lancashire, Woodnook included

AdBlue call-outs around Woodnook go to vans that serve the places near it — Scaitcliffe, Accrington plus Barnfield — and most of Lancashire further out, throughout BB postcodes.

If you're near a boundary, or somewhere hard to explain, ring and ask rather than guessing.

Anywhere your car stands — your drive at home, a side street, a parking area, a forecourt — our engineers drain it on the spot, and there's no need to bring it to us; which suits Woodnook, a residential suburb, well.

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

There's no fair single price, because the jobs aren't the same.

The cost 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 turns on where the car is and whether a technician can reach it safely, which is simpler on an open drive than in a tight spot behind Accrington War Memorial.

Ahead of any figure, never after, every call from Woodnook begins with three questions: the fuel, the quantity, plus whether the engine ran.

The answers turn a range into a straight quote.

Quoted on the call before the engineer heads out, it is paid for on the day — card or phone, nothing in advance.

Check your insurance while we're on the way: many include misfuelling cover.

## In Woodnook and still beside your car?

Right now, the most helpful thing to do with the vehicle is to not touch it.

Ignition off, engine off, keys out.

Petrol in Diesel takes over the rest, in Woodnook or wherever within Lancashire, after you ring 0333 366 0103 to say it was AdBlue, roughly what quantity, and if it ran.
