# AdBlue in the Diesel Tank in Mapperley Park? Keep It Switched Off

AdBlue in your diesel tank? Then leave your engine off — and your ignition as well.

AdBlue is urea mixed in water.

The trouble starts once it is pulled through your pump — it won't burn, and it will not combine with diesel.

Caught before the engine has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the vehicle is in Mapperley Park.

Nothing comes before ringing 0333 366 0103.

## Those opening minutes: AdBlue in the diesel tank in Mapperley Park

Do these:

- Take the keys out, so nobody switches the ignition on.

- Hazards on, if moving traffic is at all near.

- The empty bottle or the receipt tells us the fluid and the quantity, so don't bin it out.

- Ring just where you are. Quote a NG3 5 postcode or the nearest street name, and no one has to hunt for you.

Never do these:

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

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

- Pouring in more diesel doesn't work: AdBlue separates out instead of blending.

- Don't drive the car anywhere, not even a short stretch along Mapperley Park Drive.

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

Get the people behind the counter to help you move your car away from the pumps if you're on a forecourt around Mapperley Park, whether it is the Valero or somewhere else.

On your own drive, do not touch it at all.

## What AdBlue does in a diesel tank

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

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

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

Inside a diesel tank it acts very differently from fuel. It doesn't mix in.

The intake sucks fuel from the lowest part of that tank, and that is precisely where AdBlue ends up: as it is heavier than diesel, it sinks.

A car filled on a driveway in Carrington yesterday evening and not started since is the straightforward one. Nothing has pulled the AdBlue up yet — though once your engine runs, that is what goes first, straight from the bottom of the tank.

From there it does two kinds of harm.

Crystals and corrosion. As the water dries, it strands urea that crystallises in filter elements and narrow channels; and, because it eats at certain metals, each part it reaches keeps suffering for as long as it stays in there.

Lines holding AdBlue mean harm by morning for a vehicle parked in Mapperley Park. Only inside your tank, it stays the same.

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

## Why AdBlue in a diesel is frequently more significant than petrol

Petrol pumped into a diesel on Shell's forecourt makes your fuel watery — that's the main problem.

No damage comes while it sits put, blended into the diesel — only once the motor runs on it.

AdBlue in a diesel is a different matter: not thin fuel, yet no fuel at all.

Not burning, it cannot just be run through.

Nor can it be watered down, since it splits again — and the following fill will not clear away deposits or corrosion. So the flush matters for more with AdBlue, and turning your key "to see", in the heart of Mapperley Park or out in New Basford, costs more than nearly any other error.

The good news is the same as with petrol.

Anywhere across Nottinghamshire your vehicle has stopped, an unrun engine leaves the AdBlue still in the tank: the easiest bit of any fuel system to empty.

## How does AdBlue end up in a diesel tank around Mapperley Park?

Plenty of motors place the AdBlue filler beside the diesel one, occasionally behind a single flap, and after dark the two can appear identical. Nobody means it.

Mostly it's not the filling station: a driver picks up a bottle heading home and tips it in outside the house.

The ways it takes place are few and familiar.

The top-up gets rushed outside Carrington Primary and Nursery School, because the dash lit up with a warning while the kids were taken off.

Someone pours the bottle in outside their house, just off Hucknall Road, as the day ends.

Or the vehicle is topped up in the car park at The Grosvenor, in poor light, by somebody who has never opened that flap before.

The least known cars get it the most — rentals, new ones, company ones, and the other vehicle of a family with one of each fuel types.

An identical mistake, an identical first step — leave it off — wherever you happen to be in Mapperley Park or the remainder of Nottinghamshire.

## Mapperley Park: started your engine with AdBlue in your diesel tank?

Then the AdBlue has left that tank.

Via the filter, along the lines, and — given any running — on to the injection pump and every injector: that is how far it has gone.

Lumpy running, smoke, dropping power, dashboard warnings or cutting out: each may show up, perhaps midway across Mapperley Park or returning from John Farr Rest Garden.

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

Each start pulls more of that through.

If you were on the M1, under 5 miles from Mapperley Park, come off at the next junction and stop somewhere safe instead of pressing on.

Hopping across Mapperley Park to the car park by Church of Our Lady of Czestochowa is one thing; heading towards Nottingham, under 3 miles away, is another, since every mile pushes the AdBlue deeper in. So distance matters.

Approximately how far had it come? Tell us.

Wherever the car came to a stop is where all of it gets done, even with more to clean out after the motor has been running.

Noticed soon, it very rarely leaves lasting damage.

## Draining AdBlue in a diesel in Mapperley Park: what it takes

A road beside Mansfield Road Baptist Church, a driveway, a lay-by or a filling station: wherever your car has come to rest around Mapperley Park, we come to it.

What was put in, about how much, and whether the motor has been run: our engineers check before all else, because those decide the job.

The contaminated diesel and the urea leave as one when that tank is drained, on the spot.

What remains from AdBlue will not wash out by itself, so the whole system gets a full flush, which matters far more here than for petrol.

Fresh diesel goes in once the filter is cleaned — or swapped, when it needs to be — and then the vehicle is tested.

Engine not run? Then count on roughly half an hour on site for most jobs.

Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough not to disturb the street at night.

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

You drive off as soon as our engineers have started the engine, and it makes no difference whether the car is on a driveway in Mapperley Park or in a space at Nottingham.

The test before our engineers leave is that it runs correctly on clean diesel.

Since the job is done in full where the car is, a garage never comes into it.

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

## About Mapperley Park itself

Mapperley Park is a suburban area located just outside Nottingham city centre, with Mapperley Park sitting at an elevation of 63 metres above sea level. Mapperley Park forms part of the larger urban area surrounding Nottingham, with nearby places including Sherwood Rise, Forest Fields, and Alexandra Park. Mapperley Park is predominantly composed of flat housing, reflecting its character as a residential suburb. Mapperley Park is close to the city of Nottingham, being only 1 mile away from the city centre.

## AdBlue drains across Mapperley Park and Nottinghamshire

Sherwood Rise, Forest Fields and Alexandra Park are among the places around Mapperley Park that the same vans reach, along with much of Nottinghamshire beyond, over the NG postcode area.

Ring and ask instead of guessing if you're close to a county line, or somewhere awkward to explain.

Wherever the car stands — your driveway at home, a residential street, a car park, a filling station — our technicians drain it there, with no need to bring it to us; which suits Mapperley Park, a residential suburb, well.

## AdBlue in a diesel tank in Mapperley Park: the cost of fixing it

There's no fair single price, because the jobs aren't the same.

Three things shift the cost: whether your engine has been running and for how long, how much AdBlue went in, and where your car is. That last one turns on whether a technician can get to it safely, and an open drive is simpler than a tight spot behind Mount Zion Apostolic Church.

That's why each call from Mapperley Park starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it's run.

Once those are answered, a range becomes a single fixed figure.

Before a van sets off, you hear the price by phone. Then you pay on the day, by card or by phone, with nothing in advance.

Check your policy whilst we are on the way: plenty include misfuelling cover.

## Next to the vehicle in Mapperley Park, right now?

Then, touch nothing — that is the most helpful step there is.

Motor off, keys out, ignition off.

Say it's AdBlue, roughly how big an amount, and whether the engine ran, on 0333 366 0103. From there Petrol in Diesel handles it, across Mapperley Park or wherever in Nottinghamshire.
