# AdBlue in the Diesel Tank in New Deer? Keep It Switched Off

AdBlue in your diesel tank? Then keep your motor off — and your ignition too.

AdBlue is urea mixed in water.

Not like fuel, it neither burns nor blends, and nothing happens till your motor sucks it through.

A drain and a thorough flush, done where your car is in New Deer, is usually what AdBlue in a diesel tank needs — if it is caught before your motor has been run.

Nothing comes before calling 0333 366 0103.

## Your next steps straight away, New Deer: AdBlue in your diesel tank

Do:

- So nobody can turn your ignition on, take your keys out.

- If you're at all near moving traffic, put your hazards on.

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

- The van locates you quickest with a postcode starting AB53 6, or just the name of a street nearby, and so call from the spot.

Not to do:

- Moving your vehicle even a few yards is no reason to fire up your engine.

- Do not switch your ignition on. On many diesels that alone runs the fuel pump.

- Pouring in more diesel does not help: AdBlue separates out instead of thinning.

- Any driving at all is best avoided, even a short way down Main Street.

- Draining your tank on your own by the road is not one to try.

Moving the vehicle off the island is a job for attendants to help with, wherever New Deer forecourt you're on, the the nearest petrol station included.

On your own driveway, don't move it at all.

## What AdBlue does in a diesel tank

Made for the exhaust, AdBlue has no business in your engine.

Stored in a dedicated tank, it is injected into the exhaust stream to clean the gases.

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

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

It sinks, since it is denser than diesel, and pools down where the pickup takes its supply from.

Once your system runs, the AdBlue is top of the list to go through. Before then it waits beneath your diesel, which is how a vehicle filled in Auchmaliddie yesterday and not switched on stays the simple one, provided no one turns the key.

It causes two kinds of harm from there.

What is left once the water goes is urea, which turns into crystals: they lodge in narrow passages and clog filters. Worse, it attacks some metals in a fuel system, and carries on till it's flushed out.

Lines carrying AdBlue spell damage overnight for a car sitting in New Deer. Only inside the tank, it stays the same.

The water in it causes damage of its own: your high-pressure pump and your injectors depend on diesel to lubricate them, and water offers them nothing.

## Why AdBlue in a diesel is regularly more serious than petrol

Fill a diesel with petrol in error at the another forecourt nearby, and the problem is thinned fuel.

It mixes with your diesel, and whilst it is inside your tank it does no harm; the harm comes from running your engine on it.

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

It cannot simply be run through, since it does not burn.

Crystals and corrosion stay after the next fill, and AdBlue splits again from the diesel, and so watering it won't help. Hence the flush counts so much, and turning your key "to see" does more harm with AdBlue than nearly any other slip — in Drymuir or the heart of New Deer alike.

As with petrol, there's good news.

Anywhere in Aberdeenshire the vehicle has come to rest, an unstarted motor means the AdBlue yet in the reservoir: the easiest bit of any fuel system to empty.

## New Deer: how AdBlue ends up in a diesel tank

It is not on purpose. Many vehicles have the AdBlue inlet beside the diesel inlet, now and then behind one flap, and muddling them up is easy in poor light.

It usually happens outside the house, from a bottle grabbed en route home, not at the forecourt.

The ways it happens are few and familiar.

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

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

Or your car is topped up in the car park at Brucklay Arms, in poor light, by a person who has never opened that flap before.

It comes up most in a rental, a new motor, a company motor, or the spare vehicle in a family with one of each fuel types — the cars drivers use least.

Wherever across Aberdeenshire, New Deer included, the mistake doesn't change, and neither does the first response: keep it off.

## Already started the motor with AdBlue in the diesel tank around New Deer?

If so, the AdBlue is no longer in the tank.

Via the fuel filter, through the lines, and — given any running time — on to the injection pump and each injector: that's where it has gone.

Maybe returning from Den of Old Maud, or part way across New Deer, the motor may go lumpy, smoke, lose power, light up your dash or stall.

Stop when safe. Turn off. Leave the vehicle off rather than restarting it to check.

More of it is pulled through with each start.

Leave the M90, over 50 miles from New Deer, at the next junction and park safely, rather than carrying on.

Every mile carries the AdBlue further in. That's why a hop across New Deer to park near St Kane's Kirk and a drive of under 50 miles towards Aberdeen are such separate jobs.

Approximately how far had it come? Tell us.

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

Very rarely does it leave lasting damage when it is caught early.

## Clearing AdBlue in a diesel in New Deer: what it takes

Wherever it has come to rest around New Deer — a forecourt, a lay-by, a drive, a road beside New Deer War Memorial — our van travels to the vehicle.

The work depends on three answers, and our engineers ask for before all else — which fluid went in, the amount, and whether the motor has run.

Next, draining that tank on the spot takes out the polluted diesel and the AdBlue in one go.

With AdBlue, far more than with petrol, the flush counts: the whole system is cleaned all the way through since what remains will not wash away unaided.

After that, your filter: flushed, or changed when it must be. After that clean diesel, then a check of the car.

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

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

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

At that point our technicians start the engine and you set off, whether from a parking bay by the nearest station or a drive in New Deer.

Before we leave, our technicians check it's running properly with fresh diesel in.

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

You get a VAT invoice and an engineer report later, which is what insurers want.

## About New Deer and where it is

New Deer is a small village in Aberdeenshire, situated inland at an elevation of 121 metres. New Deer lies approximately 25 miles west of Aberdeen and is surrounded by nearby places such as Turfhill, Culsh, and Milltown of Auchreddie. New Deer has a population of around 549 people and predominantly features detached housing.

## New Deer and Aberdeenshire: AdBlue drains across the area

Turfhill, Culsh and Milltown of Auchreddie are among the towns around New Deer that the same teams serve, along with much of Aberdeenshire further out, throughout the AB postcode area.

Near a boundary, or anywhere tricky to explain? Asking beats assuming, and so ring.

New Deer is a rural village, and a mobile drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, we drain it where it is, and so it never needs to be shifted to us.

## AdBlue in a diesel tank around New Deer: the cost of fixing it

Since the callouts vary, a single price would not be fair.

What changes the cost is, first, whether the engine has run and for how long; then how much AdBlue got in; and finally where the car is and whether a technician can reach it safely, which is simpler on an open drive than in a tight gap behind Dingwall Fordyce Monument.

That's why every call from New Deer starts with the same three questions, asked before giving a figure, not after: what went in, how much, and whether it's run.

The answers turn a range into a straight quote.

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

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

## Still beside the car in New Deer?

Then the most handy thing you can do is nothing to the vehicle.

Engine off, keys out, ignition off.

Petrol in Diesel handles the rest, in New Deer or anywhere within Aberdeenshire, after you call 0333 366 0103 saying it's AdBlue, about how big an amount, and if it ran.
