# AdBlue in a Diesel Tank in Bournville: Why It Occurs and How to Prevent It

AdBlue already in your diesel tank? In that case set this page down a moment, keep your ignition and motor off, then ring 0333 366 0103.

Around Bournville, catching it before the motor turns normally leaves a drain and a thorough flush where it stands.

The rest of this page explains why it occurs and how to ensure it doesn't — handy if you're reading ahead of time.

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

Many modern diesels on the roads round Bournville and Ten Acres carry two liquids, not one. Diesel goes to the engine.

AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has its own filler.

Many of vehicles share a single flap for the two, while others put the AdBlue filler to your boot or under the bonnet.

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

Someone who has to stop and think where it goes usually tops up the AdBlue side, from a bottle, and much less regularly.

It is in the gap that the slip lives.

## How AdBlue in the diesel tank happens in Bournville

Carelessness rarely causes it. Instead is three things lining up together.

The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Selly Oak Road before work, or in the car park at Attic Brew Co. on the way home.

The old car's cap is where the hand reaches — yet a rental car, a new vehicle or a company car puts the fillers elsewhere. That's a second thing: a strange vehicle.

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

It takes a few seconds, whether out in Griffins Hill or bang in the centre of Bournville.

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

Before you pour anything, whether on a drive in Bournbrook or a forecourt around Bournville, check these. They take a couple of seconds.

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

- Look at the size: the smaller neck is, on many cars, the AdBlue one.

- Open the filler flap and look for a label — many cars show what goes in each inlet right there.

- Cannot see it beside your diesel inlet? Then check below the bonnet or in the boot — the owner's manual says where.

- Collecting a hire or company car, say at the car park at the nearest station? Ask the person who drove the car last before leaving, rather than once the light comes on.

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

For the day the light appears — anywhere it is across West Midlands — a simple routine to follow.

- Pull in on level, motor off, with time in hand — never hurried on the side of Oak Tree Lane.

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

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

- Finish when your tank is topped up or the bottle is empty; before that, pour slowly using the own spout.

- Before you start the vehicle, shut the cap and check a second time that your diesel cap never came off.

Spot at step two or three that it has already gone into the diesel side? So stop just there.

Don't go on to stage five.

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

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

Leave your ignition off as well, since on plenty of diesels switching it on by itself runs your pump.

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

If you are at a forecourt, whether it's the Esso or the Mary Vale Service Station, ask the staff to help roll your car clear of the petrol pump.

At home in Bournville? So the car remains put.

Already run? Pull over when it is sensible, then switch off.

Come off the Frankley Services Southbound — under 5 miles out of Bournville — at the next exit.

Distance counts — a short hop across Bournville is a smaller job than driving under 5 miles to Birmingham — so tell us about how far it went.

## What happens when we get there around Bournville

The van reaches your car anywhere it has come to rest — your own driveway, beside Bournville Carillon, or outside Bournville Village Primary.

Those answers decide the work and our price, so our engineers ask what was put in, about how much, and whether it's run.

No one heads out until you have had our price over the phone.

Then your tank is drained and the system flushed thoroughly.

More than with petrol, it counts here: the crystals build up, some metals are attacked, and none of it clears out unaided, no matter how long it sits.

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

We don't leave until it has been fired up and is running smoothly.

Using pumps safe on a working forecourt and quiet enough for use outside a house at night, most jobs in which your engine hasn't run take about half an hour after our engineers arrive.

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

It is worth looking at your insurance while we travel to you: misfuelling cover is included with plenty of policies.
