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

Leave the motor and ignition off then call 0333 366 0103 first — the rest can wait if AdBlue is already in the diesel tank.

Normally, if your motor hasn't turned, it is emptied and fully flushed where the car is around Round Hill.

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

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

Plenty of current diesels on the roads round Round Hill and Cutsyke carry two liquids, not one. Diesel goes to your motor.

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

Different tanks, different fillers.

Other motors keep the AdBlue filler in your boot or under the bonnet; a lot more place both together behind one flap.

Topping up the diesel side at the petrol pump goes on all the time.

The AdBlue side is topped up far less commonly, usually from a bottle, and usually by somebody who has to stop and think where it goes.

It's in the gap that the error lives.

## Round Hill: how AdBlue in your diesel tank happens

Carelessness rarely explains it. Instead is three things lining up at once.

On a driveway off Love Lane before work, or in the car park outside Roundhill Road Club on the way home: that is where the rushed top-up takes place. Why the rush? As AdBlue gets low the car warns you, and once it's gone, limp mode follows.

Then your car is unfamiliar. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand hits for the cap it would have used on the old one.

A spout-topped bottle finds no obstacle at a diesel filler any more than at an AdBlue one. And so the tip, once begun, carries on.

It takes seconds, be it out in Half Acres or right in the centre of Round Hill.

## How to tell the AdBlue filler from the diesel one

Before you tip anything, whether on a drive in Castleford Ings or a forecourt in Round Hill, check these. They take a few seconds.

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

- Many cars give AdBlue the smaller filler of the two.

- The flap. Look inside the fuel flap for a label. Many vehicles say there which fuel goes where.

- The handbook shows which it is when the filler isn't next to the diesel cap: the boot, or under the bonnet.

- Whoever had it before will know. Check when you collect a hire car or fleet car — from Castleford's car park, say — rather than when the light comes on.

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

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

- Pull in somewhere level, engine off, with time in hand — never rushing on the side of Beancroft Road.

- Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and reading it. Daft, yes, but it does the trick.

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

- Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty.

- Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car.

Find at step two or three that it's already gone into the diesel side? Then stop just there.

Never go on to step five.

## AdBlue in the diesel tank already, in Round Hill?

The short order of things, beginning with no starting the motor.

Do not switch your ignition on; on plenty of diesels that alone runs the fuel pump.

AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is drawn from — so don't top up with diesel to thin it.

At a forecourt — the nearest petrol station, Asda or any other — the attendants will normally help roll the vehicle clear, if you ask.

At home around Round Hill? Then the car remains put.

Where the engine has been run already, pull over safely then turn it off.

Round Hill sits under a mile from the M62; there, use the first exit.

About how far did it go? Crossing Round Hill is smaller work than a trip of under 10 miles towards Wakefield, so tell us.

## Our arrival around Round Hill, and what happens next

Wherever the car has stopped, whether by Half Acres Primary Academy, near Smawthorne Community Church or at home, the van comes to it.

Which liquid got in, the amount, and if it ran: our engineers ask because those replies set both work and quote.

On the call itself, you hear the quote — before anything else.

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

Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of it washes away unaided. Hence it matters more.

Testing comes at the end: before that, clean diesel goes in, and the filter is cleaned or replaced if necessary.

Next our engineers fire it up and check it runs correctly before we leave.

Unstarted cars mostly need a half-hour job after the moment we arrive. The kit is safe on a live filling station, and hushed enough for a driveway late at night.

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

It's worth checking your insurance as the van travels to you: misfuelling cover is included with many policies.

## AdBlue drains about Round Hill, and West Yorkshire beyond

Hightown and Castleford are among the towns around Round Hill, a residential suburb, that the same teams cover, over WF postcodes.

A postcode starting WF10 5 gets our van to you fastest.

Shifting the car is not necessary.

Wherever it stands — near Smawthorne Community Project @ The Link, on a lay-by heading to Quarry Park, at home — that is where it is emptied.

Assuming doesn't help behind St Michaels and All Angels Church, on a border, or somewhere hard to pin down; ring and ask.

## In short, for Round Hill drivers

Always, the cap; after that, the pour.
