# AdBlue in the Diesel Tank in Windy Arbor? Keep It Switched Off

If AdBlue has gone into the diesel tank, keep the engine off and leave the ignition off.

Water with urea mixed in it: that is AdBlue.

Unlike fuel, it neither ignites nor blends, and nothing happens till your motor sucks it round.

If your engine has not run yet, AdBlue in a diesel tank is usually emptied and thoroughly purged where your car sits around Windy Arbor.

Before anything, ring us on 0333 366 0103.

## Windy Arbor, AdBlue in the diesel tank: what to do at once

Things to do:

- Remove your keys, which stops someone switching the electrics on.

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

- Which fluid, and roughly how much volume? Save the bottle or the receipt, and our technicians can see.

- Call us from where you are. A postcode starting L35 1, or the name of the closest street, brings the van to you without a search.

Never do these:

- Shifting the vehicle just a few yards is no reason to fire up your engine.

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

- No extra fuel on top. The AdBlue will not blend, and so it's pointless.

- Any driving at all is best avoided, even a short way along Windy Arbor Brow.

- Draining the tank on your own beside the road is not worth trying.

The attendants working at any Windy Arbor filling station — the Shell included — will normally lend a hand rolling it clear if you ask.

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

## What does AdBlue do in a diesel tank?

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

Its own reservoir holds it, and from there it is sprayed into your exhaust, and there it treats the gas.

A fuel pump isn't made to take it, and AdBlue was never supposed to go through one.

Fuel mixes; AdBlue, once poured in, will not. Its behaviour is not at all like fuel's.

Denser than diesel, it sinks and pools below it — the very spot the intake draws from.

The first thing the fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Huyton Park last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in.

After it's pulled in, the harm takes two forms.

It attacks certain metals found in fuel components, working on any part it touches till it is removed from your system. And when the water evaporates, the urea forms crystals that clog filters and lodge in tiny channels.

Where the AdBlue has reached the pipework, leaving it overnight in Windy Arbor leaves things worse. Inside the tank only, time does nothing.

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

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

Petrol put into a diesel on Esso's forecourt makes the fuel watery — that's the main problem.

Damage just comes from running on it. Mixed into your diesel and sitting inside that tank, it causes none.

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

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

It does not stay mixed, and so it cannot be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting the motor "to see" costs more here than nearly anywhere else, whether the vehicle is in Tarbock Green or the middle of Windy Arbor.

The good news is the same as with petrol.

Emptying a tank is the simplest part on a fuel system, and without start-up, the AdBlue stays in there — wherever around Merseyside the car sits.

## How does AdBlue end up in a diesel tank in Windy Arbor?

It is not on purpose. Plenty of cars keep the AdBlue inlet alongside the diesel inlet, occasionally under a single flap, and mixing them up is simple in poor light.

A bottle bought while driving home and tipped in at home, instead of at the filling station, is the usual story.

The ways it happens are few and familiar.

A warning light comes on during the school run, and the top-up takes place in a hurry outside Halsnead Primary School.

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

Another pattern: darkness, a pub car park outside Brewers Fayre, and a driver using that flap the first time.

The least familiar vehicles see it most — hire cars, new ones, company ones, and the other car in a home with both fuels.

Anywhere in Merseyside, Windy Arbor included, the slip does not change, and neither does the first response: leave it off.

## Windy Arbor: started the motor with AdBlue in the diesel tank?

If so, the AdBlue is no longer in that tank.

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

Lumpy running, smoke from the exhaust, dropping power, dashboard warnings or cutting out: any might show up, maybe part way across Windy Arbor or coming back from Round Clump.

Stop when it is safe. Turn off. Leave it off instead of testing it again.

Each start pulls more of that through.

If you were on the M57, under a mile from Windy Arbor, come off at the next exit and stop somewhere sensible instead of pressing on.

How far it went counts. A few hundred yards across Windy Arbor to the car park by St Nicholas Church is a very different job from a run towards Liverpool, under 10 miles away, with the AdBlue reaching further into your system with every mile.

Roughly how far had it come? Tell us.

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

When it is noticed early, long-term damage is very rare.

## Clearing AdBlue in a diesel around Windy Arbor: what it takes

Wherever it has stopped around Windy Arbor — a filling station, a layby, a drive, a street beside Saint Leo's Church — our van comes to the car.

Three replies shape the job, so before anything else our technicians ask which fluid went in, roughly the amount, and if the engine has turned over.

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

Residue from AdBlue won't wash away by itself, and so the whole system gets a careful flush, which counts much more with urea than for petrol.

Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested.

Not run? Then count on roughly half an hour once we are there for most jobs.

Explosion-proof pumps mean a busy forecourt sensible to work on, and they're quiet enough to spare the neighbours at night.

Priming the system with clean diesel comes last.

After that our technicians start the car and you head off, whether from a parking bay at Whiston or a driveway in Windy Arbor.

Before we go, our technicians confirm it's running smoothly with clean diesel in.

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

Insurers want a VAT invoice and an engineer report, and you get both at the end.

## About Windy Arbor and where it is

Windy Arbor is a suburban area in Merseyside, situated on the riverside with an elevation of around 37 metres. Windy Arbor lies approximately 7 miles from Liverpool, within the North West region of England. Windy Arbor is characterized by its semi-detached housing and is located near other local areas such as Whitefield Lane End and Whiston. Windy Arbor is a relatively small community, with a population of around 994 residents.

## AdBlue drains in Windy Arbor and across Merseyside

Whitefield Lane End, Huyton Quarry and Whiston are among the places near Windy Arbor that the same teams serve, along with most of Merseyside further out, over the L postcode area.

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

Windy Arbor is a residential suburb, and an on-site 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 does AdBlue in a diesel tank cost to sort out around Windy Arbor?

Because the jobs differ, a single figure wouldn't be honest.

Whether the engine has been running, and for how long, comes first in what changes the price. How much AdBlue got in comes next, and then the position of the car, since an open drive is easier for a technician to reach safely than a tight gap behind George Howard Centre.

Which fluid was put in, how much, and if it ran: each Windy Arbor enquiry opens by asking precisely that, ahead of a figure, not afterwards.

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

Quoted by phone before the van sets out, the job is paid for on the day — card or phone, nothing in advance.

Misfuelling cover is part of many insurance policies, so it is worth looking at yours before the van arrives.

## Windy Arbor: still alongside your car?

Then, the best thing to do with the vehicle is to not touch it.

Keys out; motor and ignition off.

Ring 0333 366 0103 then tell us it is AdBlue, roughly how much, and if it's run. Petrol in Diesel takes it from there, around Windy Arbor or anywhere in Merseyside.
