# Don't Start It: AdBlue in a Diesel Tank in Wick Hill

If AdBlue has gone into the diesel tank, leave your motor off then leave the ignition off.

In plain terms, AdBlue is just urea in water.

The harm begins once it's pulled through the pump — it won't ignite, and it won't combine with diesel.

In Wick Hill, AdBlue in a diesel tank caught before your engine runs usually means a drain and a thorough flush, just where the car is.

No step comes before calling 0333 366 0103.

## Wick Hill, AdBlue in the diesel tank: what to do straight away

Things to do:

- Remove the keys, and that prevents anyone turning the electrics on.

- Hazards on, if moving traffic is anywhere close.

- So you can tell us which fluid it was and about how much, save the receipt or the empty bottle.

- Ring us from where you are. A postcode starting RG12 2, or the name of the nearest street, gets our van to you without a search.

Not to do:

- No starting your engine — not for a second, not to shift the vehicle.

- The ignition stays off: on many diesels, switching it on is enough to start the pump.

- Don't top up with diesel to thin it. AdBlue does not dilute in diesel; it separates out.

- Don't drive the car anywhere, not even a short way along Holly Spring Lane.

- No emptying it yourself, either, on the roadside.

Get the attendants to help you move your vehicle away from the pumps if you're at a forecourt around Wick Hill, whether it is the Tesco or somewhere else.

On the drive, the vehicle remains just as it was left.

## What does AdBlue do in a diesel tank?

AdBlue is made for the exhaust, not your engine.

It goes into its own tank and is sprayed into your exhaust gas to fresh it.

A fuel pump isn't designed to take it, and AdBlue was never supposed to travel through one.

Inside a diesel tank it behaves very differently from fuel. It does not mix in.

The pickup takes fuel from the deepest part of the tank, and that's precisely where AdBlue settles: as it is denser than diesel, it sinks.

Easiest of all: one that had AdBlue in Whitegrove overnight and has not been started since. The liquid waits at the foot of your tank, untouched — though it would be first through if the engine starts, ahead of any diesel at all.

It causes two kinds of harm from there.

It eats at some metals used in fuel components, attacking whatever it touches until it's cleared from the system. And when the water goes, the urea turns into crystals that block filters and lodge in tiny passages.

Where the AdBlue has reached the pipework, waiting till morning in Wick Hill makes it worse. In that tank alone, time does nothing.

And there is the water: it brings no lubrication to the components that rely on it the most — the high-pressure pump and each injector.

## AdBlue in a diesel: why it is commonly worse than petrol

Fill a diesel with petrol by mistake over at the Esso, and the issue is diluted fuel.

Mixed into your diesel and left unused, it is no threat at that stage; using the motor is the harm.

AdBlue in a diesel is a problem of the wrong substance altogether.

It can't simply be run through, since it does not burn.

It doesn't stay mixed, and so it cannot be diluted. And crystals and corrosion do not wash out with the next tank of fuel. That is why the flush counts more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether the vehicle is in Skimpedhill or the middle of Wick Hill.

The good news is the same as with petrol.

Never run? Then the AdBlue sits just inside that tank, the easiest section of the whole system to empty, anywhere your car has stopped across Berkshire.

## How AdBlue ends up in a diesel tank around Wick Hill

Many motors put the AdBlue cap alongside the diesel cap, now and then under a single flap, and in dim light the two can appear identical. No one means it.

Usually it is not the filling station: a driver picks up a bottle heading home and pours it in outside the house.

It tends to happen in a few familiar ways.

A warning light comes on during the school run, and the top-up occurs in a hurry outside Sandy Lane Primary School.

Near Goughs Lane, someone pours a bottle in on the drive after work.

Or someone unfamiliar with that flap refills the vehicle in dim light, parked in the car park outside The Boot.

It comes up the most in a hire car, a brand-new car, a company motor, or the other vehicle in a home with both fuels — the cars people use least.

Wherever you are in Wick Hill or the rest of Berkshire, it's the same mistake and the same first answer: leave the car off.

## AdBlue in the diesel tank in Wick Hill, and the motor started?

Then your tank is no longer where the AdBlue is.

The filter and pipework have had it sucked through, and some running takes it on to the high-pressure pump and every injector.

You may notice your engine running unevenly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from The Elms Recreation Ground or halfway across Wick Hill.

When you safely can, pull over then turn it off — without turning it on again to see.

With each start, more of that is pulled through.

If you were on the A329(M), under 3 miles from Wick Hill, come off at the next exit and stop somewhere safe rather than pressing on.

A quick hop across Wick Hill to the car park by Bracknell (Central) Library is one matter; heading for Westminster, under 50 miles away, is something else, since every mile pushes the AdBlue deeper in. So mileage matters.

Roughly how far had it come? Tell us.

Our engineers do all of the rinsing where the vehicle has stopped, and once the engine has been started there is more of it.

Very rarely does it leave permanent damage when it is noticed early.

## What does an AdBlue drain on a diesel involve around Wick Hill?

Wherever it has stopped in Wick Hill — a forecourt, a layby, a drive, a road beside Fenwick — the van comes to your vehicle.

What went in, roughly the quantity, and whether your motor has turned over: our engineers ask first, since those shape the work.

Right there, your tank is then emptied, and both the contaminated diesel and the urea leave at once.

A full flush matters far more after AdBlue than after petrol, since what remains won't clear out by itself.

After that, the fuel filter: flushed, or replaced if it has to be. After that clean diesel, and then a check of your car.

Not run? Then count on about half an hour on site for most jobs.

Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough to spare the neighbours at night.

The final step is to bleed your system on clean diesel.

You head off as soon as we have started it, and it makes no difference whether the car is on a drive in Wick Hill or in a bay at Bracknell.

It is tested on new diesel to confirm it runs properly before our engineers go.

We do it all wherever the vehicle has stopped, and it never needs to be taken to a workshop.

You get a VAT invoice and an engineer report afterwards, which is what insurers ask for.

## About Wick Hill, for a moment

Wick Hill is a suburban area in Berkshire, situated on the riverside with an elevation of 87 metres. Wick Hill lies near the towns of Bracknell and Bullbrook, and is characterized by a high proportion of flat housing. Wick Hill is located approximately 27 miles from London, making it a commuter base for those working in the capital. Wick Hill is also close to the village of Newell Green, and forms part of the wider urban area around Bracknell.

## Wick Hill and Berkshire: AdBlue drains across the area

AdBlue jobs around Wick Hill are passed to teams that cover the places around it — Bracknell, Bullbrook as well as Newell Green — and most of Berkshire beyond, across RG postcodes.

Near a border, or somewhere tricky to pin down? Asking is better than guessing, and so ring.

Wherever your vehicle stands — a drive at home, a residential street, a car park, a filling station — we empty it on the spot, and there's no need to take it to us; that suits Wick Hill, a residential suburb, well.

## What does AdBlue in a diesel tank cost to sort out in Wick Hill?

Since the callouts differ, a flat figure would not be honest.

The price changes first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that was put in. After that it turns on where the car is and whether a technician can get to it safely, which is simpler on an open driveway than in a tight gap behind The Lexicon.

Before any figure, never after, each enquiry from Wick Hill begins with the same three questions: the liquid, the amount, and whether the engine ran.

The answers turn a range into a straight quote.

Quoted by phone before the engineer heads out, the job is settled on the day — card or phone, nothing in advance.

While our engineer is on the way, dig out your policy: plenty cover misfuelling.

## Still beside your car around Wick Hill?

In that case, touch nothing — that's the best move there is.

Ignition off, motor off, keys out.

Phone 0333 366 0103: AdBlue, the amount, and whether it ran is all our technicians need. Petrol in Diesel takes over the rest throughout Berkshire, Wick Hill too.
