# AdBlue in the Diesel Tank in Cranswick? Keep It Switched Off

With AdBlue in your diesel tank, your ignition stays off and so does your engine.

In plain terms, AdBlue is simply urea in water.

It does not burn, it doesn't mix with diesel, and the damage it does begins when the system draws it in.

In Cranswick, AdBlue in a diesel tank caught before the engine runs usually comes down to a drain and a thorough flush, right where the car is.

No step comes before calling 0333 366 0103.

## Cranswick, AdBlue in your diesel tank: what to do at once

To do:

- Pocket the keys, and that stops someone switching the electrics on.

- Put the hazard lights on if you are at all near moving traffic.

- Keep the receipt or the empty bottle, and so you can tell us what was put in and roughly how much.

- Ring right where you are. Say a YO25 9 postcode or the nearest street sign, and no one has to search for you.

Not to do:

- Do not start the motor, even for a moment to move the car.

- Plenty of diesels run their fuel pump the moment the ignition goes on, so keep the car off.

- Adding extra diesel doesn't work: AdBlue settles out instead of thinning.

- Do not drive it anywhere, not even a short distance up Londesborough Road.

- No draining it yourself, at all, on the verge.

The staff on duty at any Cranswick forecourt — the Rix included — will normally help pushing it clear if you ask.

Parked on your own driveway? Then it stays exactly where it is.

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

The engine is not what AdBlue is made for; the exhaust is.

Its own tank keeps it, and from there it's fed into the exhaust, where it treats the gas.

Nothing inside an injection pump is designed for this fluid — and no part of that was intended to go through one.

Tipped in with the diesel, it keeps apart rather than blending — quite unlike fuel.

Heavier than diesel, it sinks and collects below it — the very place the pickup sucks from.

The first thing your fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Cawkeld last night, and hasn't been started since, is still the easy case: the AdBlue is lying at the bottom of your tank, and nothing has sucked it in.

Once it's drawn in, the harm takes 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 running on the parts it hits for as long as it stays there.

By daybreak, a car parked in Cranswick with AdBlue in its lines gets worse; where it is only in your tank, it doesn't.

Water lubricates nothing. The injection pump and each injector depend on diesel flowing through them, and so the water part damages them in its own right.

## AdBlue in a diesel: why it's often worse than petrol

Top up a diesel with petrol in error over at the JET, and the problem is thinned fuel.

Damage just comes from driving on it. Mixed into your diesel and sitting inside the tank, it causes nothing.

AdBlue in a diesel is another problem: not thin fuel, but no fuel at all.

It does not burn, so it cannot just be run through.

Nor can it be thinned, since it separates again — and the following tankful will not rinse away deposits or corrosion. So the flush counts for more here, and trying the engine "to see", in the centre of Cranswick or out in Kilnwick, does more harm than nearly any other error.

As with petrol, there's good news.

Anywhere around East Riding of Yorkshire your car has stopped, an unrun engine means the AdBlue yet in the tank: the simplest part of any fuel system to clear.

## How does AdBlue end up in a diesel tank in Cranswick?

After dark, two caps together — the AdBlue cap and the diesel cap, now and then behind a single flap — may appear the same. No one intends it; plenty of layouts allow it.

It usually occurs outside the house, from a bottle bought on the journey home, not at the filling station.

It tends to occur in a couple of familiar ways.

Rushing, outside Hutton Cranswick Community Primary School, after a warning light flashed on during the school run, someone refills the car.

A bottle is poured in at the end of the day on a drive just off Beverley Road.

Else, after dark by The White Horse, your vehicle is topped up by a driver using that flap for the first time.

Rented motors, new cars, company cars, or the spare vehicle in a family with one of each: the least known vehicles see it most.

Anywhere in East Riding of Yorkshire, Cranswick included, the mistake does not change, and nor does the first response: keep it switched off.

## Started the motor with AdBlue in the diesel tank in Cranswick?

The AdBlue has left the tank, then.

Through the filter, along the lines, and — with any running time — on to the high-pressure pump and every injector: that is where it has gone.

You may notice your motor running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Centenary Wood or halfway across Cranswick.

Pull over when it is safe. Turn off. Keep the vehicle off rather than testing it again.

Each start pulls more of that through.

Cranswick sits under 25 miles from the M62; if you were on it, leave at the next junction and stop somewhere safe rather than carrying on.

Every mile pushes the AdBlue further into your system. That's why crossing Cranswick to park near St Peter's Church and a drive of under 25 miles towards Kingston upon Hull are such distinct jobs.

Tell us roughly how far it had come.

Our technicians do all of the rinsing where your car has come to a stop, and once the motor has been run there is more of it.

Caught soon, it very seldom leaves long-term damage.

## What emptying AdBlue from a diesel involves around Cranswick

The car stays where it is, whether that's a street near Walton Abbey Remains, a drive, a lay-by or a forecourt around Cranswick, and our van comes to it.

Which fluid went in, roughly how much, plus if the engine has been run: our engineers check before all else, because those shape the job.

The contaminated diesel and the urea come out together after the tank is drained, right there.

The fuel system is flushed thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own.

A test of the vehicle follows at the end, after clean diesel goes in and your filter gets cleaned or, where necessary, swapped.

The majority of these jobs are a half-hour visit once our engineers turn up, if the engine has not run.

Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough to spare the street at night.

Bleeding the system with fresh diesel comes at the end.

You head off as soon as our technicians have fired it up, and it makes no difference whether your car is on a driveway around Cranswick or in a bay by Hutton Cranswick.

Our technicians make sure it runs smoothly on clean diesel before we leave.

Our engineers do it all wherever the vehicle has stopped, and it never has to go to a garage.

The insurer will want an engineer's report and the VAT invoice — both yours afterwards.

## AdBlue drains across Cranswick and East Riding of Yorkshire

Over the YO postcode area, the vans taking AdBlue jobs around Cranswick reach much of East Riding of Yorkshire too, Hutton Cranswick, Hutton and Watton included.

Assuming won't help by a border or anywhere tricky to pin down; ring and check.

Wherever your car stands — a drive at home, a side street, a car park, a forecourt — our engineers drain it there, with no need to take it to us; which suits Cranswick, a residential suburb, well.

## Cranswick: what AdBlue in a diesel tank costs to fix

Each job is different, so not one fixed price would be fair.

Whether the engine has run, and for how long, comes first in what changes the price. How much AdBlue got in comes next, and then the location of the vehicle, since an open drive is easier for a technician to reach safely than a tight spot behind St Mary.

What got in, what quantity, plus whether it ran: every Cranswick call begins by asking exactly those, ahead of any quote, never after.

Those replies turn a range into a straight quote.

Before a van heads out, you hear the quote on the phone. Then you pay on the day, card or over the phone, with nothing upfront.

Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.

## Alongside the car in Cranswick, still?

Then, the most helpful thing to do with your car is to leave it.

Ignition off, engine off, keys out.

Tell us it's AdBlue, roughly what quantity, and if the engine ran, on 0333 366 0103. From there Petrol in Diesel handles it, across Cranswick or anywhere in East Riding of Yorkshire.
