# Preventing AdBlue in a Diesel Tank in Lower Bunbury: Why It Happens

AdBlue already in the diesel tank? Then set this page aside for now, keep your ignition and motor off, then ring 0333 366 0103.

Around Lower Bunbury, finding it before your engine runs normally leaves a drain and a thorough flush where it stands.

If you are reading before it has happened, the remainder of this page is about why it occurs and how to make sure it does not.

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

Plenty of newer diesels around Higher Bunbury, as well as Lower Bunbury, run on two liquids; the engine gets only the diesel.

The exhaust, not the motor, is where AdBlue goes: sprayed into the fumes to fresh them, from its own tank.

Separate tanks, separate fillers.

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

Filling the diesel side at the petrol pump happens constantly.

Rarely filled, AdBlue normally goes in out of a bottle, tipped by someone who has to stop and think what filler it needs.

The mistake lives in that gap.

## Lower Bunbury: how AdBlue in your diesel tank occurs

Carelessness rarely explains it. Instead is three things coming up together.

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

Unfamiliar motors come next, as well. Rentals, new cars and company vehicles put their fillers in new places, and the hand reaches for the cap used on the old one.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour once it has started.

It's a few seconds, be it out in Bunbury or bang in the heart of Lower Bunbury.

## The AdBlue filler and your diesel filler: telling them apart

Whether a Lower Bunbury forecourt or a driveway out in Woodworth Green, take a few seconds on these before any is poured in.

- The cap. The AdBlue cap is regularly blue, or marked "AdBlue". The diesel cap usually isn't. Read it rather than going by position.

- On many motors, size gives it away: AdBlue has the smaller filler neck.

- Open the filler flap and check for a label — plenty of motors mark what goes in which filler just there.

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

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

## How to top up without AdBlue in your diesel tank

For the day the light comes on — wherever you are around Cheshire — a routine to follow.

- Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of Bunbury Lane.

- Silly as it sounds, saying "AdBlue" aloud while you unscrew the cap works — after you have located the filler and read the cap.

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

- Stop once the tank is topped up or the bottle is empty; until then, tip slowly using the built-in spout.

- Shut the cap, and look once more — making sure the diesel cap stayed closed the whole time. Only then, start your car.

Find at stage two or three that it has already gone into your diesel side? So stop right there.

Never go on to step five.

## Put AdBlue in your diesel tank in Lower Bunbury already?

Do not start the engine: that's where the short order of things begins.

Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump.

Filling up with diesel will not dilute it: rather than mixing, AdBlue drops to the bottom of that tank, just where fuel is taken from.

If you are at a forecourt, whether it is the Texaco or the another forecourt nearby, ask the attendants to help push the car away from the pump.

Leave it where it is if you are on your own driveway around Lower Bunbury.

When the engine has run already, pull over somewhere safe and switch the car off.

Lower Bunbury lies under 15 miles from the M53; there, use the next exit.

Roughly how far did it go? Hopping across Lower Bunbury is less a job than a trip of under 15 miles to Chester, and so say.

## Lower Bunbury: what happens when our engineers turn up

Our engineers come to the car wherever it has stopped, whether that's outside Bunbury Aldersey CofE Primary School, near Bunbury Village Hall or on your own drive.

The answers decide this work and our quote, so we ask what got in, about how much, and if it's run.

You hear that quote by phone, before anyone heads out.

Emptying the tank comes next, followed by a full flush of the system.

More than with petrol, it counts with AdBlue: crystals form, some metals are attacked, and none of that clears away unaided, however long it sits.

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

The engine is fired up next and tested to be sure it runs smoothly, all before we leave.

Using pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs where your engine has not run take about half an hour once our engineers are there.

Payment is on the day, not upfront, and you receive the paperwork your insurer asks for: an engineer's report and a VAT invoice.

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

## Lower Bunbury and Cheshire: AdBlue drains across the area

Over CW postcodes, our teams that cover Lower Bunbury — a residential suburb — work the nearby spots too, Spurstow and Bunbury Heath included.

Quickest of all: give a CW6 9 postcode for our van.

The vehicle remains where it is.

A driveway, a lay-by on the way to Peckforton Wood, a side street close to St Boniface: our engineers drain the vehicle where it is.

If you're near a boundary, or somewhere hard to explain like the back of Bunbury Mill, ring and ask rather than guessing.
