# Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Higherfence

If AdBlue is already in your diesel tank, stop reading for a moment: leave the motor and the ignition off and ring 0333 366 0103.

Normally, if the motor has not run, it's emptied and fully cleaned where your vehicle sits around Higherfence.

Here before the event? Then the rest explains how it comes about and what to prevent it happening at all.

## AdBlue in a diesel vehicle, and its separate tank

Many newer diesels in Macclesfield, as well as Higherfence, carry on two fluids; your motor takes just the diesel.

Your exhaust, not the engine, is where AdBlue ends up: dosed into the fumes to fresh it, from its own tank.

Each tank has its own filler.

Some motors put the AdBlue filler in the boot or under the bonnet; plenty of others have both side by side behind one flap.

Topping up the diesel side at the pump goes on constantly.

Seldom filled, AdBlue normally goes in out of a bottle, tipped by a driver who has to stop and think what filler to use.

It's in the gap that the mistake happens.

## How AdBlue in your diesel tank takes place in Higherfence

Carelessness seldom causes it. Instead is three things lining up at once.

On a drive off Waverley Close before work, or in the car park at Puss in Boots on the way home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue runs low the vehicle warns you, and if it is gone, limp mode kicks in.

The old car's cap is where the hand goes — yet a rental car, a new vehicle or a company car puts the fillers somewhere else. That is a second factor: a new car.

No part stops the tip once it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits.

Whether it happens in Hurdsfield or the middle of Higherfence, it is the same few seconds.

## Which filler is for AdBlue, and which for diesel?

A few seconds is all the checks take — so check them before you pour anything, on a driveway in Kerridge-end or a forecourt around Higherfence.

- Read the cap rather than going by position: AdBlue ones are frequently blue or marked "AdBlue", and diesel ones normally aren't.

- Many cars fit AdBlue the smaller filler of the two.

- Check inside the fuel flap: many motors carry a label there showing which fuel goes where.

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

- Collecting a hire or company car, say at the car park outside Macclesfield? Check with the person who drove the car last before you set off, not once the light goes on.

## Topping up AdBlue without it reaching the diesel tank

Anywhere across Cheshire the light comes on, here is a routine for the day.

- Stop on level, engine off, with time in hand — never hurried on the side of Lark Hall Crescent.

- Locate the AdBlue filler, read the cap, and say the word "AdBlue" aloud while you unscrew it. It sounds daft. It does the trick.

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

- Gently is best, through the bottle's own spout, until it is full or the bottle is empty.

- Only after that, start the vehicle: close the cap, check once more, and make sure the diesel cap was never opened.

Stop there if you find, at stage two or three, that you've already poured into your diesel side.

Never go on to stage five.

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

Don't start the engine: that's where the short order of things begins.

The fuel pump runs on many diesels the moment the ignition goes on — and so keep it off.

Don't top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from.

Ask the staff to help push the vehicle away from the petrol pump if you're at a forecourt — the Tesco, the Esso or somewhere else.

On your own drive around Higherfence? So the car stays put.

Already run? Stop once it's safe, then switch off.

The next junction is the place to come off if you're on the M56, under 15 miles from Higherfence.

Distance counts — a quick hop across Higherfence makes a smaller job than driving under 25 miles to Manchester — so tell us roughly how far it went.

## When our technicians get there in Higherfence, what happens?

We come to the car wherever it has stopped, whether that is outside Puss Bank School and Nursery, close to Holy Trinity Church or on your own drive.

Both the work and the price depend on three replies — which liquid, which amount, and whether it has run — so we ask.

You get that price on the phone, before anyone heads out.

Then your tank is emptied and your system rinsed thoroughly.

Much more than with petrol, it matters here: crystals form, certain metals are attacked, and none of that clears away on its own, however long it sits.

The filter flushed or, if it must be, replaced; fresh diesel in; and then a test of the vehicle.

Before leaving, our technicians fire it up and make sure that it is running correctly.

Unrun cars usually need a half-hour job after the moment we arrive. The equipment is fine on a live forecourt, and quiet enough for a residential street after dark.

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

Before we get there, have a look at your policy; many carry cover for misfuelling.

## AdBlue drains around Higherfence and across Cheshire

Higherfence is a residential suburb, and our vans that cover it also work the towns near it, Higher Hurdsfield and Calrofold among them, across the SK postcode area.

Fastest of all: quote a SK10 1 postcode to our van.

The vehicle doesn't need to shift.

A drive, a lay-by on the way to Brynmore Park, a side street near St Paul's Church: our technicians drain the car where it stands.

Ring and ask rather than assuming if you are close to a border, or somewhere hard to describe, like the back of St Peter's Church.
