# Preventing AdBlue in a Diesel Tank in Newall Green: Why It Happens

AdBlue already in your diesel tank? Then put this page aside for now, leave the ignition and engine off, then call 0333 366 0103.

Caught before the motor runs, it is generally a drain and a thorough flush, done where your car is in Newall Green.

Nothing happened yet? Further down, the page covers the reasons it occurs and the ways to avoid it altogether.

## Why does AdBlue in a diesel vehicle need its own filler?

Many newer diesels in Woodhouse Park, like those in Newall Green, carry on two liquids; your motor takes only your diesel.

AdBlue's own tank holds it, and from there it goes to your exhaust, and there spraying cleans the fumes.

There is a filler for each tank.

Plenty of cars share a single flap for the two, whereas others put the AdBlue filler to your boot or under the bonnet.

At the petrol pump, the diesel side gets filled constantly.

Someone who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and far less often.

The error lives in that gap.

## Newall Green: how AdBlue in your diesel tank occurs

Rarely is it carelessness: usually three things coincide.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Malling Road before work, or in the car park outside The Newall Green on the way home.

Next, your hand reaches for the cap it knew on the old motor — since a rental car, a new car or a company car puts the fillers somewhere your last one did not.

Lastly, the bottle goes in: a diesel filler or AdBlue one, it goes in just as easily, and once the tip begins, nothing halts it.

It's a few seconds, whether out in Wythenshawe or bang in the centre of Newall Green.

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

Before you pour anything, whether on a driveway in Davenport Green or a forecourt around Newall Green, check these. They take a couple of seconds.

- The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap usually is not. Read it rather than going by where it sits.

- On many cars, the size tells: AdBlue has the smaller filler neck.

- A label inside the fuel flap frequently says which fuel goes where, on plenty of motors. Look for it.

- The handbook. If the filler is not by your diesel cap, it's in your boot or under the bonnet, and the handbook says which.

- Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Manchester Airport.

## AdBlue top-ups that never reach your diesel tank

A routine for the day the light comes on, wherever around Greater Manchester that is.

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

- Daft as it sounds, speaking "AdBlue" aloud while you unscrew the cap works — once you have located the filler and read it.

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

- Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.

- Close the cap, then look once more — confirm the diesel filler stayed shut throughout. After that, start the car.

Find at the second or third stage that AdBlue went into the wrong tank? That's where you stop.

Don't go on to stage five.

## Newall Green: already put AdBlue in your diesel tank?

Brief order, then. First: the motor remains off.

Keep the ignition off too, since on many diesels it alone starts your pump.

Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is pulled from.

Ask the attendants to help roll the car clear of the pump if you are at a forecourt — the BP, the Shell or somewhere else.

At home in Newall Green? So the car stays put.

Stop as soon as it is safe then switch off, if your engine has already run.

The next junction means the place to leave when you're on the M56, under a mile from Newall Green.

Distance matters — a quick hop across Newall Green is a smaller job than driving under 10 miles to Salford — so tell us about how far it went.

## Our arrival around Newall Green, and what takes place next

Anywhere your car has stopped, be it outside St Peter's Catholic Primary School, near Newall Green Baptist Church or on your own drive, our van travels to it.

We ask what was put in, roughly how much, and if it's run, because the replies settle this work and the quote.

The quote is given over the phone, ahead of any van leaving.

Next: draining, then a full flush of the whole system.

Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of that clears out by itself. That is why it counts more.

The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested.

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

If your motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark.

Paying happens on the day, not upfront, and you are given the documents an insurer wants: an engineer report and a VAT invoice.

While we travel, have a look at your policy; many include cover for misfuelling.
