# Avoiding AdBlue in a Diesel Tank in Locking Parklands: Why It Happens

If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and your ignition off then phone 0333 366 0103.

A drain plus a full flush, carried out just where your vehicle stands around Locking Parklands, is normally all it takes when found before the motor runs.

If you are reading before it has happened, the rest of this page is about why it takes place and how to make sure it doesn't.

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

Not one fluid but two: that's how plenty of modern diesels near Locking Parklands and Woolvers Hill carry, with diesel for the engine.

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

Every tank has a filler of its own.

Some motors put the AdBlue filler in your boot or under the bonnet; a lot more have both side by side behind one flap.

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

A driver who has to stop and think where it goes normally tops up the AdBlue side, from a bottle, and far less regularly.

The slip lives in that gap.

## AdBlue in the diesel tank around Locking Parklands: how it takes place

Three things tend to line up, and carelessness is rarely one of them.

To start with, the warning. Low AdBlue brings a message from your car, and running out means limp mode — hence a hurried top-up, perhaps before work off Lower Parade Ground Road, or outside The Coach House on the way home that evening.

Then, your hand reaches for the cap it knew on the old vehicle — because a hire car, a new vehicle or a company car puts the fillers where your last one did not.

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

Locking or the heart of Locking Parklands: it is the same few seconds in both.

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

A couple of seconds is all the checks take — so check them before you tip anything, on a drive in Knightcott or a forecourt in Locking Parklands.

- Position can mislead; the cap does not. AdBlue ones are often blue or bear the word "AdBlue" — diesel caps usually do not.

- Plenty of motors fit AdBlue the smaller neck of the two.

- A label inside your fuel flap frequently says which fuel goes where, on many vehicles. Look for it.

- The handbook says where it is if the filler isn't next to the diesel cap: your boot, or under the bonnet.

- Picking up a hire or company car, say at the car park at Worle? Ask whoever drove it last before you set off, rather than once the light comes on.

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

For the day the warning comes on — anywhere you are around Somerset — a simple routine to use.

- Switch off once parked — flat ground, engine off, and never rushed beside Engineers Gardens on the verge.

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

- The diesel cap stays on. Where both sit under a flap, confirm it's closed before the bottle comes up.

- Finish when the tank is topped up or the bottle runs dry; until then, pour gently using the own spout.

- Only after that, start the car: close the cap, check again, and make sure your diesel cap was never opened.

Find during the second or third stage that AdBlue went in the diesel tank? That's where you stop.

Don't carry on to step five.

## Locking Parklands: already put AdBlue in your diesel tank?

The short order of things, beginning with not starting your motor.

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

Topping up with diesel will not thin it: instead, AdBlue sinks to the base of your tank, just where fuel is drawn from.

The attendants at Asda Express, Morrisons or another forecourt will normally lend a hand to push the vehicle away if asked.

If you're on your own drive around Locking Parklands, leave it where it stands.

Stop as soon as it is safe then switch off, if the engine has already run.

Locking Parklands lies under a mile from the M5; there, take the first junction.

A short hop across Locking Parklands is a smaller job than a run towards Wells, under 15 miles away, so tell us about how far it went.

## What takes place when our technicians arrive in Locking Parklands

The van reaches your car wherever it stopped — your own drive, beside RAFLAA Monument, or by Parklands Educate Together Primary.

Both the work and our quote depend on three answers — which liquid, what quantity, and if it's run — so our technicians ask.

During the phone call itself, you are told our quote — ahead of dispatch.

After that: a drain, then a full flush of the whole system.

AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol.

Filter cleaned or, if it must be, swapped; clean diesel in; and then a test of the vehicle.

Before we leave, our engineers start it and confirm that it's running properly.

If your motor has not run, most jobs take about half an hour once we're there, using pumps that are fine on a working forecourt and quiet enough to use outside a house after dark.

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

Before we get there, have a look at your policy; many include cover for misfuelling.
