# How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Fall Bank

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

Caught before your engine runs, it is normally a drain and a thorough flush, done where your car is in Fall Bank.

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

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

No single fluid but two: that's how many modern diesels around Fall Bank and Dodworth Bottom carry, with diesel for the engine.

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

Separate tanks, different fillers.

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

The diesel side is fuelled at the pump all the time.

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

The error lives in that gap.

## How AdBlue in the diesel tank happens around Fall Bank

Seldom is it carelessness: normally three things coincide.

On a driveway off Manchester Road before work, or in the car park outside Dodworth Tap heading 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 once it's gone, limp mode kicks in.

Then the car is new. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and your hand hits for the cap it would have used on the old one.

No part stops the pour after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits.

Dodworth or the heart of Fall Bank: it is the same few seconds either way.

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

A few seconds is all these take — so check them before you tip anything, on a drive in Keresforth Hill or a forecourt in Fall Bank.

- Check the cap rather than going by where it sits: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps normally are not.

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

- Open the flap and check for a label — many cars mark which goes in each inlet just there.

- Can't find it next to your diesel filler? In that case check beneath the bonnet or in your boot — the handbook will say where.

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

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

For the day the warning appears — anywhere it is in South Yorkshire — a simple routine to follow.

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

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

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

- Finish once that tank fills or the bottle runs dry; before that, tip gently using its own spout.

- Close the cap, and look once more — making sure your diesel cap remained shut throughout. After that, start the vehicle.

Discover at the second or third stage that the bottle went in the wrong filler? That's where you stop.

Step five is out.

## Already put AdBlue in your diesel tank in Fall Bank?

Brief order, then. Top of it: the motor remains off.

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

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

The staff at Asda, Jet or another forecourt will usually help pushing your car clear when asked.

Leave it where it is if you're on your own drive in Fall Bank.

Stop as soon as it is safe and switch off, if the motor has already run.

Fall Bank sits under a mile from the M1; there, use the first exit.

About how far did it go? Hopping across Fall Bank is smaller a job than a run of under 10 miles towards Wakefield, so tell us.

## Fall Bank: what occurs when our engineers arrive

The van comes to your car anywhere it has come to rest — your own drive, near Collins Close Community Centre, or by Dodworth St John the Baptist CofE Primary Academy.

Those replies decide the work and our price, and so our engineers ask what went in, roughly how much, and if it's run.

During the call itself, you are told the quote — ahead of anything else.

Then that tank is drained and the system cleaned thoroughly.

Not like petrol, AdBlue forms crystals and attacks some fuel-system metals, and neither washes away unaided. That is why it matters more.

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

Before we go, we start the engine and check that it is running smoothly.

Unrun cars mostly mean a half-hour visit from arrival. The kit is fine on a live filling station, and quiet enough for a residential street after dark.

Your insurer will ask for the engineer's report and your VAT invoice, and you get both at the end. Payment is on the day, with no deposit.

Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way.
