# Why It Happens and How to Prevent It: AdBlue in a Diesel Tank in Pontefract

Leave the motor and ignition off then phone 0333 366 0103 first — reading can wait when AdBlue is already in your diesel tank.

Caught before the motor runs, it is usually a drain and a thorough flush, done where the vehicle is around Pontefract.

Reading before the event? In that case the rest covers how it comes about and how to prevent it ever happening.

## AdBlue in a diesel motor: two tanks, two fillers

Many modern diesels around Grove Town, as well as Pontefract, carry on two fluids; the motor takes only your diesel.

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.

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.

The diesel side is topped up at the pump all the time.

The AdBlue side is filled far less regularly, usually from a bottle, and normally by a person who has to stop and think where it goes.

That gap is where the error lives.

## How AdBlue in the diesel tank occurs around Pontefract

It is seldom carelessness. Three things tend to line up.

First, the warning. Low AdBlue triggers a message from the vehicle, and letting it run out leads to limp mode — hence a hurried top-up, perhaps before work off Baxtergate, perhaps at Horse Vaults on the way home after work.

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

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 tip after it has started.

It takes seconds, whether out in Marl Pits or bang in the heart of Pontefract.

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

A few seconds is all the checks take — so run through them before you pour anything, on a driveway in Chequerfield or a forecourt in Pontefract.

- Colour and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position.

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

- A label inside your fuel flap frequently shows which fuel goes where, on plenty of vehicles. Look for it.

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

- The previous driver will know. Check when you collect a hire car or fleet car — at Pontefract Baghill's car park, say — rather than once the warning appears.

## Keeping AdBlue out of the diesel tank when you top up

A routine for the day the light comes on, wherever across West Yorkshire that is.

- Turn off after you park — level ground, engine stopped, and never in a rush beside Finkle Street at the roadside.

- Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works.

- The two behind one flap? So make sure the lid on your diesel filler stays shut ahead of lifting the bottle.

- Stop once that tank is topped up or the bottle runs dry; until then, pour gently using the built-in spout.

- Before starting the vehicle, close the cap and check again that the diesel cap was never came off.

Find during the second or third step that the bottle went into the diesel filler? That is where you stop.

Don't carry on to step five.

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

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

On plenty of diesels your ignition alone runs the fuel pump, so don't switch the vehicle on.

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

If you are at a forecourt, whether it's the Murco or the Shell, ask the staff to help push the car away from the petrol pump.

Your own driveway in Pontefract is the place it stays.

If the motor has already run, stop as soon as it is safe then switch off.

Pontefract lies under 3 miles from the M62; on it, take the first junction.

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

## What takes place when our technicians arrive in Pontefract

We come to your car wherever it has stopped, whether that's outside St Giles C of E Academy, near Magna Carta Memorial or on your own drive.

Our technicians ask what got in, about how much, and if it has run, because the replies settle the work and our quote.

On the phone call itself, you are told our price — before anything else.

Then that tank is emptied and your system cleaned thoroughly.

Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and none of that clears out unaided. Hence it counts more.

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

After that our technicians start the engine and check it runs properly before we go.

Most jobs are done in roughly half an hour after our technicians arrive, provided the engine hasn't run — and the pumps we use are safe on a busy forecourt yet quiet after dark outside a house.

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

It's worth checking your insurance while we travel to you: misfuelling cover comes with many policies.
