# AdBlue in the Diesel Tank in Church Green? Keep It Switched Off

Motor off, ignition off: that's how you start if AdBlue has gone into your diesel tank.

Urea dissolved in water is all AdBlue is.

The harm starts once it is sucked through the lines — it won't ignite, and it will not combine with diesel.

In Church Green, AdBlue in a diesel tank caught before the motor runs normally means a drain and a thorough flush, right where your car is.

Before you do anything else, call 0333 366 0103.

## Those opening minutes: AdBlue in the diesel tank around Church Green

Do:

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

- If you're anywhere close to moving traffic, put the hazards on.

- Hold on to the till receipt or the empty bottle, and so you can tell us what was put in and about how much.

- Call us from where you are. A postcode starting WA13 0, or the name of the nearest street, gets our van to you without a search.

Not to do:

- Not even briefly, and not to roll the car: the engine remains off.

- The ignition remains off: on lots of diesels, turning it on is enough to start your fuel pump.

- Pouring in more diesel does not work: AdBlue settles out rather than blending.

- Keep the car where it is rather than driving it anywhere, even a short stretch up Higher Lane.

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

Moving the car off the pumps is a job for staff to help with, wherever Church Green forecourt you are on, the Shell included.

At home, the car remains just where it was left.

## AdBlue in a diesel tank, and what it does there

Not the engine but your exhaust is where AdBlue is meant to go.

From a dedicated reservoir it goes directly to the exhaust, treating what your engine lets out.

Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

Fuel blends; AdBlue, once poured in, won't. Its behaviour is not at all like fuel's.

It sinks, because it's heavier than diesel, and pools low where the pickup takes its supply from.

Once the system runs, the AdBlue is first to go through. Until then it waits underneath your diesel, which is why a vehicle filled in Rushgreen yesterday and not switched on remains the straightforward one, provided no one turns the key.

After it is pulled in, the damage comes in two forms.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it's corrosive to some of the metals a fuel system is made from, so it keeps working on the components it hits for as long as it stays there.

By daybreak, a car sitting around Church Green with AdBlue in its lines gets worse; if it is only inside your tank, it doesn't.

Water protects nothing. The high-pressure pump and each injector depend on diesel flowing past them, and so the water part damages them in its own right.

## Why is AdBlue in a diesel frequently the bigger fault?

Petrol put into a diesel on another forecourt nearby's forecourt leaves the fuel watery — that is the main fault.

Harm just comes from driving on it. Mixed into your diesel and sitting in the tank, it causes none.

With AdBlue in a diesel, the liquid itself is plainly the wrong one.

It can't just be run through, because it does not burn.

Nor can it be watered down, because it splits again — and the following fill won't clear away crystals or corrosion. So the flush matters more here, and turning your key "to see", in the heart of Church Green or out in Oughtrington, does more harm than almost any other error.

With AdBlue, the good news is no distinct from petrol.

Wherever around Cheshire the vehicle has come to rest, an unrun engine leaves the AdBlue yet inside the tank: the easiest part of a fuel system to empty.

## AdBlue in a diesel tank around Church Green: how it ends up there

After dark, two caps side by side — the AdBlue one and the diesel one, occasionally under a single flap — can look the same. No one intends it; plenty of layouts allow it.

Mostly it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

The ways it takes place are few and familiar.

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

Near Rectory Lane, someone tips a container in on the drive after work.

Or a driver unfamiliar with that flap tops up your car in dim light, stopped in the car park outside the pub in the village.

It crops up most in a hire car, a brand-new vehicle, a company vehicle, or the spare vehicle in a family with both fuel types — the vehicles drivers know the least.

Keep it switched off: that's the first response to the same slip, wherever in Church Green or the remainder of Cheshire you happen to be.

## Started the engine with AdBlue in the diesel tank in Church Green?

The AdBlue has left the tank, then.

The filter and pipework have had it pulled along, and some running takes it on to the high-pressure pump and each injector.

Rough running, smoke from the exhaust, lost power, dashboard lights or stalling: each may appear, perhaps midway across Church Green or returning from The Sunken Garden.

Stop as soon as it is safe, switch off, and do not restart it to check.

Each start pulls more of it through.

On the M6, under 3 miles from Church Green, the next junction is where to leave, and anywhere safe is where to stop — not carrying on.

Distance counts: every mile carries the AdBlue further in, so heading for Salford, under 15 miles away, gives a much larger job than hopping across Church Green to the car park by St Mary's Church.

Tell us about how far it had come.

Once the engine has been run, the flush takes in more, and all of it is done where your car has stopped.

Very seldom does it leave long-term damage when it is caught early.

## What does an AdBlue drain on a diesel involve around Church Green?

We come to the vehicle, wherever it has stopped in Church Green: a side street close to Lymm Dam, a drive, a lay-by or a forecourt.

Before anything else we ask what got in, about how much, and whether your motor has been run, because those replies determine the work.

Next, emptying the tank on the spot removes the polluted diesel along with the AdBlue together.

With AdBlue, more so than with petrol, the flush counts: the fuel system is cleaned right through since what remains won't wash away unaided.

After that, the filter: flushed, or replaced when it has to be. After that fresh diesel, then a check of your vehicle.

Engine not run? Then count on roughly half an hour once we are there for most jobs.

The equipment is explosion-proof, so a busy forecourt is no fault, and it is quiet enough for a residential street after dark.

Fresh diesel goes in to bleed your system, and that is the final step.

You set off as soon as our engineers have fired it up, and it makes no difference whether the vehicle is on a driveway around Church Green or in a bay at Birchwood.

Before leaving, our technicians confirm it's running smoothly with new diesel in.

As the job is done in its entirety where the car is, a garage never comes into it.

Insurers want a VAT invoice and an engineer report, and both come at the end.

## Church Green and Cheshire: AdBlue drains across the area

Phone and ask instead of guessing when you're by a border, or anywhere awkward to pin down.

Wherever the car stands — your driveway at home, a side street, a parking area, a filling station — we empty it there, and there's no need to take it to us; that suits Church Green, a residential suburb, well.

## What AdBlue in a diesel tank costs to put right in Church Green

Because each jobs vary, a flat price wouldn't be honest.

Three things change the cost: whether the engine has run and for how long, how much AdBlue was put in, and where the vehicle is. That last one comes down to whether our van can reach it safely, and an open driveway is simpler than a tight gap behind Lymm Lawn Tennis and Croquet Club.

What went in, what quantity, and whether the engine ran: every Church Green call begins by asking exactly those, ahead of a figure, not afterwards.

With those replies, the range shrinks to a single firm figure.

Before a van heads out, you are told the quote on the phone. And payment is on the day, card or over the phone, with nothing upfront.

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

Petrol in Diesel takes over the rest, across Church Green or wherever in Cheshire, once you ring 0333 366 0103 saying it's AdBlue, about how big an amount, and if the engine ran.
