# AdBlue in the Diesel Tank in Toll Bar? Keep It Switched Off

Motor off, ignition off: that is where you start if AdBlue has got into your diesel tank.

AdBlue is urea mixed in water.

Being water-based, it will not ignite and won't blend with diesel; trouble only starts when the pump starts drawing it.

If the motor hasn't run yet, AdBlue in a diesel tank is generally emptied and carefully purged where the vehicle stands around Toll Bar.

No step comes before ringing 0333 366 0103.

## AdBlue in the diesel tank in Toll Bar: the first few minutes

Do these:

- Keys out — that way no one can switch anything on.

- Close to moving traffic? So put the hazards on.

- So you can tell us which fluid it was and roughly how much, keep your receipt or the empty bottle.

- Ring us from where you are. A postcode starting DN5 0, or the name of the nearest street, gets our van to you without a search.

Don't:

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

- Many diesels power their fuel pump the instant your ignition goes on, so leave the vehicle off.

- No more fuel added. The AdBlue will not blend, so it is wasted.

- Do not drive it anywhere, not even a short stretch up Hall Villa Lane.

- No draining it yourself, at all, at the roadside.

Get the attendants to help you move your vehicle away from the island if you're on a forecourt in Toll Bar, whether it is the JET or elsewhere.

At home, the car stays just as it is.

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

Not the motor but the exhaust is where AdBlue is meant to go.

Its own reservoir holds it, and from there it's fed into your exhaust, where it cleans the gas.

No part in a fuel pump is made for this fluid — and no part of it was meant to travel through one.

Fuel blends; AdBlue, once poured in, will not. Its behaviour is nothing like diesel's.

The pickup sucks fuel from the deepest part of that tank, and that's exactly where AdBlue ends up: being denser than diesel, it sinks.

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

From there it causes two kinds of damage.

What remains once the water evaporates is urea, which forms crystals: they lodge in tiny channels and clog filters. On top of that, it attacks some metals in a fuel system, and carries on till it is flushed out.

If the AdBlue is in the pipework, waiting overnight in Toll Bar makes things worse. Inside that tank alone, waiting does nothing.

Diesel protects the high-pressure pump and every injector as it passes; water gives no lubrication, which is a separate form of harm.

## AdBlue in a diesel: why it is frequently worse than petrol

Put petrol in a diesel at the Esso and you have a problem of thin fuel.

Damage only comes from running on it. Blended into the diesel and left in that tank, it does none.

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

Because it doesn't burn, running it through isn't an option.

Deposits and corrosion stay after the next fill, and AdBlue separates again from the diesel, and so watering it won't work. That is why the flush counts more, and turning your key "to see" does more harm with AdBlue than nearly any other slip — in Woodlands East or the heart of Toll Bar alike.

As with petrol, there is good news.

If the motor hasn't run, the AdBlue is still inside the tank, and that tank is the easiest part of a fuel system to clear, wherever across South Yorkshire your car is standing.

## AdBlue in a diesel tank in Toll Bar: how it ends up there

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

Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

A couple of familiar ways cover the majority of them.

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

After work, a bottle goes in on a driveway close to Villa Gardens.

Otherwise, in dim light outside the pub in the village, the vehicle gets topped up by a driver opening that flap the first time.

It occurs most in the cars motorists know least: a hire car, a new vehicle, a company car, or the second motor of a household with one diesel and one petrol.

Wherever you're in Toll Bar or the remainder of South Yorkshire, it is the same mistake and the same first answer: leave the vehicle off.

## Already started the engine with AdBlue in the diesel tank in Toll Bar?

The AdBlue has left that tank, then.

It has been drawn through your filter and the lines, and if your engine ran for any time, it has got to the high-pressure fuel pump and the fuel injectors.

Lumpy running, smoke, dropping power, dashboard lights or stalling: each may show up, maybe part way across Toll Bar or returning from Bentley Colliery FC.

Stop as soon as it is safe, switch off, and don't restart the car to check.

Every start pulls more of that through.

If you were on the A1(M), under 3 miles from Toll Bar, come off at the next exit and stop somewhere safe instead of pressing on.

Every mile pushes the AdBlue further into the system. That's why crossing Toll Bar to park beside St Philip & St James and a drive of under 5 miles towards Doncaster are very separate jobs.

Let us know roughly how far it had come.

We do all of the flushing where your car has come to a stop, and once your engine has run there is more of it.

Spotted early, it very rarely leaves permanent damage.

## Toll Bar: how AdBlue is drained from a diesel

A street by St Joseph & St Teresa's, Askern, a drive, a layby or a filling station: anywhere your vehicle has stopped in Toll Bar, we travel to it.

Three replies shape the work, so first we ask what went in, about the amount, and if the engine has run.

On the spot, the tank is then emptied, and all of the contaminated diesel and the urea come out at once.

A full flush matters far more after AdBlue than with petrol, because residue won't clear away by itself.

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

Roughly half an hour on site is usual for most jobs when the motor hasn't run.

Explosion-proof pumps make a live forecourt safe to work on, and they run quiet enough to spare the neighbours at night.

Bleeding the system with fresh diesel comes at the end.

After that our technicians start it and you set off, whether from a parking space by Adwick or a driveway in Toll Bar.

The test before we go is that it runs correctly on clean diesel.

We do it all wherever your car has ended up, and it never needs to go to a garage.

Insurers ask for a VAT invoice and an engineer report, and you get both at the end.

## About Toll Bar itself

Toll Bar is a small village in South Yorkshire, situated near the town of Doncaster and close to the villages of Rostholme and Shaftholme. Toll Bar lies in a low-lying area, with an elevation of around 6 metres, and is characterized by its semi-detached housing stock. Toll Bar is located near Carcroft Common and is part of the wider Doncaster urban area.

## AdBlue drains across Toll Bar and South Yorkshire

AdBlue call-outs in Toll Bar are passed to teams that serve the places near it — Rostholme, Shaftholme plus Carcroft Common — and much of South Yorkshire beyond, throughout DN postcodes.

Near a boundary, or anywhere tricky to pin down? Checking is better than guessing, and so phone.

Toll Bar is a rural village, and a mobile drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it stands, and so it never needs to be moved to us.

## What AdBlue in a diesel tank costs to put right around Toll Bar

Not one single price would be honest, because each job differs.

Whether the motor has been running, and for how long, comes first in what moves the cost. How much AdBlue went in comes next, and then the location of the vehicle, since an open drive is simpler for a technician to reach safely than a tight spot behind Bentley Baptist Church.

Before a figure, not after, every enquiry from Toll Bar begins with three questions: the fuel, the quantity, plus whether it ran.

Those replies narrow the range right down to a single figure.

The quote is quoted during the call, before anyone sets off; settling up comes on the day, by card or by phone, and nothing upfront.

Misfuelling cover comes with many insurance policies, so it is worth looking at yours before the van arrives.

## Toll Bar: still next to the car?

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

Keys out, engine off, ignition off.

Say it's AdBlue, about what quantity, and if the engine ran, on 0333 366 0103. From there Petrol in Diesel takes over, in Toll Bar or anywhere within South Yorkshire.
