# Atticall: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It?

Pause reading a minute if the diesel tank already has AdBlue in it: ignition off, engine off, then phone 0333 366 0103.

A drain plus a thorough flush, done right where the vehicle sits in Atticall, is usually all it needs when caught before the motor runs.

The remainder of this page explains why it takes place and how to make sure it doesn't — useful if you are reading ahead of time.

## AdBlue in a diesel vehicle: two tanks, two fillers

Diesel feeds your motor — yet plenty of modern diesels seen around Atticall and Annalong carry another fluid too.

The exhaust, not your motor, is where AdBlue ends up: dosed into the gas to fresh it, from a separate tank.

There's a filler on each tank.

On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet.

Diesel gets filled at every filling station visit, again and again.

The AdBlue side is filled far less commonly, usually from a bottle, and usually by somebody who has to stop and think where it goes.

That gap is where the error lives.

## Atticall: how AdBlue in your diesel tank happens

Seldom is it carelessness: normally three things line up.

Hurry comes from the warning. The vehicle warns you as AdBlue runs low, and an empty tank puts the vehicle into limp mode — so the top-up gets done in a rush, before work on a driveway off B7041, or heading home in the car park at the pub in the village.

Unfamiliar cars are second, too. Rentals, new motors and company cars put their fillers in new places, and the hand goes for the cap used on the old one.

Third, the spout fits: diesel filler or AdBlue filler, it slides in as readily, and once the tip starts, nothing stops it.

It takes a few seconds, be it in Killowen or bang in the heart of Atticall.

## How to tell the AdBlue filler from the diesel one

Before you pour anything, whether on a driveway in Rostrevor or a forecourt in Atticall, check these. They take a couple of seconds.

- Check the cap instead of going by where it sits: AdBlue caps are commonly blue or marked "AdBlue", and diesel caps usually aren't.

- On many vehicles, size gives it away: AdBlue gets the smaller filler neck.

- Lift the flap and check for a label — many motors mark what belongs in each inlet just there.

- In the boot or under the bonnet: that's where the filler is if it's not by your diesel cap, and the handbook tells you which.

- The person who drove it last. On a hire or company car collected from somewhere like the car park at the nearest station, ask before you leave, not when the light comes on.

## Topping up AdBlue without it reaching the diesel tank

For the day the light comes on — wherever you are in County Down — a simple routine to use.

- Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of B7065.

- Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and reading it. Daft, yes, yet it works.

- If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave it on.

- Slowly does it, through the bottle's own spout, till it is full or the bottle is empty.

- Only then, start the vehicle: close the cap, check again, and make sure the diesel cap was never opened.

Spot at step two or three that it's already gone into the diesel side? Then stop right there.

Don't go on to step five.

## Atticall: already put AdBlue in your diesel tank?

Then the order of things is short. Don't start the motor.

Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump.

Topping up with diesel will not weaken it: rather than mixing, AdBlue sinks to the bottom of that tank, right where fuel is drawn from.

If you are at a forecourt, whether it is the the nearest petrol station or the another forecourt nearby, ask the attendants to help roll your car clear of the pump.

At home in Atticall? Then your car remains where it is.

If your motor has already run, stop as soon as it is safe then switch off.

On the M77, over 50 miles from Atticall, that means the next junction.

About how far did it go? Crossing Atticall is smaller work than a run of under 15 miles to Newry, and so say.

## When we arrive around Atticall, what happens?

Wherever the car has stopped, be it by the local primary school, near the centre or on your own drive, the van comes to it.

Our engineers ask what was put in, about how much, and if it has run, because those replies decide this work and the price.

You hear that quote on the phone, before anybody sets off.

Draining the tank comes next, followed by a thorough flush of your system.

With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own.

Once the filter has been cleaned — or renewed, where needed — fresh diesel goes in, and finally the car gets tested.

We don't go until it has been started and is running properly.

Unrun cars mostly mean a half-hour job after arrival. The kit is safe on a live filling station, and quiet enough for a residential street late at night.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

Plenty of insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.

## About Atticall, briefly

Atticall is a small locality in County Down, situated inland at an elevation of 131 metres, approximately 13 miles from Newry. Atticall is characterised by its predominantly detached housing stock, reflecting its rural setting.

Atticall is located in the picturesque countryside of Northern Ireland, some 305 miles from London.

## AdBlue drains in Atticall and across County Down

Being a small village, Atticall shares its vans surrounding areas — Kilkeel, Dunnaval — right across BT postcodes and the wider area beyond.

Quickest of all: quote a BT34 4 postcode for the van.

The car doesn't need to move.

Anywhere it sits — beside a street just off the centre, in a lay-by en route to the green space at the edge of the village, at home — that's where it gets emptied.

If you're close to a border, or somewhere hard to describe like the back of the far end of the built-up part, ring and ask instead of assuming.

## For Atticall people, the short version

First, the cap; then, the pour.

Petrol in Diesel empties it on the spot, anywhere across County Down, if AdBlue has gone in your diesel tank all the same — and so leave it off then call 0333 366 0103.
