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

AdBlue in your diesel tank? Then leave your engine off — and the ignition too.

Chemically, AdBlue is just urea in water.

Not like fuel, it neither ignites nor mixes, and no harm starts until the motor sucks it through.

A drain and a thorough flush, done where the vehicle is in Howell, is normally what AdBlue in a diesel tank needs — if it is caught before the engine has been run.

Before anything, phone us on 0333 366 0103.

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

To do:

- Remove your keys, and that prevents someone turning the power on.

- Near moving traffic? Then put the hazard lights on.

- The empty bottle or your receipt shows us the product and the amount, so do not throw it away.

- Ring just where you are. Say a NG34 9 postcode or the closest street sign, and no one has to search for you.

Not to do:

- Not even for a second, and not to roll your car: your engine remains off.

- Many diesels run their pump the instant the ignition comes on, and so leave the car off.

- AdBlue doesn't dilute in diesel — it separates out — so adding extra fuel won't thin it.

- Even a short stretch down Howell Fen Drove is too far to drive the vehicle.

- By the road, do not attempt emptying it yourself.

Ask the people behind the counter to help you move your car off the island if you're at a forecourt in Howell, whether it's the Power or somewhere else.

At your own driveway, do not touch it at all.

## What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not the engine.

Stored in a separate tank, it's squirted into the exhaust to treat the gases.

A fuel pump is not made to cope with it, and AdBlue was never supposed to go through one.

Tipped in with the diesel, it stays separate rather than mixing — quite unlike fuel.

The pickup sucks fuel from the lowest part of that tank, and that is just where AdBlue settles: as it is denser than diesel, it sinks.

A car filled on a drive in Asgarby overnight and left unstarted is the simple one. Nothing has pulled the AdBlue up yet — but once the engine runs, that is what is pulled first, straight from the bottom of the tank.

Once it is pulled in, the damage takes two forms.

What remains once the water goes is urea, which turns into crystals: they settle in narrow passages and block filters. On top of that, it attacks certain metals in the fuel system, and keeps going until it is flushed out.

If the AdBlue is in the lines, leaving it till morning in Howell leaves it worse. In the tank only, waiting costs nothing.

Then there's the water: it offers no lubrication to the parts that need it most — the high-pressure pump and each injector.

## Petrol or AdBlue in a diesel: why AdBlue is commonly worse

Put petrol in a diesel at the Tesco and you have a fault of thin fuel.

Blended into your diesel and sitting still, it is no threat at that stage; running the motor does the damage.

The issue with AdBlue in a diesel is a completely wrong liquid.

Not burning, it cannot just be run through.

Nor can it be watered down, since it separates back out — and the following fill will not clear away crystals or corrosion. So the flush counts for more with AdBlue, and trying the engine "to see", in the centre of Howell or out in Heckington, does more harm than almost any other error.

The good news is the same as with petrol.

Not run? Then the AdBlue waits only inside your tank, the simplest section of the whole system to clear, anywhere your vehicle has stopped around Lincolnshire.

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

Nobody means to do it. The AdBlue filler on many vehicles sits right next to your diesel filler, occasionally under the same flap, and the two caps can look alike in poor light.

A bottle bought while driving home and tipped in at home, rather than at the forecourt, is the typical route.

Usually, it happens in one of a few familiar ways.

The top-up is rushed outside Heckington St Andrew's Church of England School, after your dash lit up with a warning as the kids were dropped in.

In the evening, a bottle goes in on a driveway near Heckington Road.

Or your car is topped up in the car park at the pub in the village, in poor light, by somebody who has never opened that flap before.

Rented motors, new motors, fleet cars, or the second car in a family with both fuels: the least familiar vehicles get it most.

Anywhere around Lincolnshire, Howell included, the mistake doesn't change, and nor does the first step: keep it off.

## Started the motor with AdBlue in your diesel tank around Howell?

Then the AdBlue has left the tank.

With any running time, it travels to the injection pump and every injector, having passed via your filter and lines.

Maybe returning from Fox Covert, or part way across Howell, your motor might go rough, smoke, drop power, flash your dash or cut out.

No starting it again to test: stop when safe, then turn everything off.

Each start pulls more of that through.

Howell sits under 50 miles from the Great North Road; if you were on it, exit at the next junction and stop safely rather than carrying on.

Mileage counts: every mile pushes the AdBlue deeper into the system, and so driving towards Lincoln, under 25 miles away, gives a far bigger job than crossing Howell to the car park by St Oswald.

Roughly how far it had come is worth telling us.

Wherever the car came to a stop is where all of it gets done, even with more to clean out once your engine has been started.

When it's spotted early, long-term damage is very unusual.

## What draining AdBlue from a diesel involves around Howell

A road by St. Andrew, a driveway, a layby or a filling station: wherever your car has stopped in Howell, our technicians travel to it.

Three replies shape the work, and so before anything else we ask what went in, about what quantity, plus if your engine has run.

Next, draining the tank on the spot takes out the polluted diesel along with the AdBlue together.

A full flush matters far more after AdBlue than with petrol, since what remains won't wash out on its own.

Next, the filter: cleaned, or replaced if it must be. After that clean diesel, and then a check of your car.

Engine not run? Then expect about half an hour once we are there for most jobs.

The pumping gear is explosion-proof, so a live filling station is no issue, and it's hushed enough for a residential street late at night.

The final step is to prime the fuel system on new diesel.

Whether it's a parking bay outside Heckington or a drive around Howell, that is where our engineers start the engine and you drive off.

We check it runs smoothly on clean diesel before we go.

Our technicians do it all wherever the car has ended up, and it never has to be taken to a garage.

Insurers ask for a VAT invoice and an engineer report, and both come afterwards.

## About Howell, briefly

Howell is a small hamlet in Lincolnshire, situated in a low-lying area of the East Midlands at an elevation of around 12 metres. Howell lies near the villages of Boughton, Ewerby Thorpe, and Ewerby, and is approximately 18.6 miles from the city of Lincoln. Howell has a population of around 500 people, with a predominance of detached housing. Howell is located inland, about 103.6 miles north of London.

## Howell and Lincolnshire: AdBlue drains across the area

AdBlue call-outs around Howell are passed to vans that cover the places near it — Boughton, Ewerby Thorpe plus Ewerby — and much of Lincolnshire further out, across NG postcodes.

If you are close to a boundary, or somewhere hard to describe, ring and ask rather than assuming.

Wherever your car stands — a driveway at home, a side street, a parking area, a filling station — we empty it there, with no need to take it to us; which suits Howell, a rural hamlet, well.

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

Not one flat price could be honest, since each job is different.

Whether the engine has been running, and for how long, comes first in what moves the price. How much AdBlue went in comes next, and then the position of the vehicle, because an open drive is simpler for a technician to reach safely than a tight spot behind Ewerby Reading Room.

That is why every call from Howell starts with the same three queries, asked before giving a figure, not after: what went in, how much, and if it has run.

With those replies, a range narrows to a single fixed number.

Before anyone sets off, you are told the quote by phone. And you pay on the day, card or over the phone, with nothing in advance.

Misfuelling cover is part of plenty of insurance policies, so it is worth looking at yours before the van gets there.

## Alongside your car around Howell, right now?

Then, the best thing to do with your vehicle is to not touch it.

Keys out; motor and ignition off.

Petrol in Diesel takes over the remainder, across Howell or anywhere within Lincolnshire, once you phone 0333 366 0103 saying it's AdBlue, about how big an amount, and if the engine ran.
