# Bilston: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in your diesel tank, your ignition remains off and so does the motor.

AdBlue is urea mixed in water.

Not like fuel, it neither ignites nor blends, and nothing happens till your motor pulls it round.

In Bilston, AdBlue in a diesel tank found before your motor runs usually means a drain and a thorough flush, just where the car is.

Nothing comes before ringing 0333 366 0103.

## AdBlue in the diesel tank around Bilston: the first few minutes

Do:

- Keys out — then nobody can power anything on.

- Put the hazards on if you are at all close to moving traffic.

- Which fluid, and about how much volume? Save the bottle or the receipt, and we can know.

- Ring just where you are. Quote a EH25 9 postcode or the nearest street sign, and nobody has to hunt for you.

Don't:

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

- Switching the key to ignition alone starts the pump going on plenty of diesels. Avoid it.

- Do not top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.

- Any driving at all is best avoided, including a short stretch up Meadow Place.

- Beside the road, do not try draining it on your own.

The attendants working at any Bilston forecourt — the Asda among them — will usually help rolling it clear if you ask.

If you're on your own drive, leave the vehicle just where it stands.

## What AdBlue does in a diesel tank

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

Kept in a dedicated tank, it's squirted into the exhaust stream to treat the gases.

Neither side fits the other: urea does not belong in a pump, and an injection pump can't deal with urea.

Poured in with your diesel, it stays apart rather than blending — entirely unlike fuel.

Denser than diesel, it sinks and pools underneath it — the very place the intake sucks from.

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

Once it is drawn in, the harm takes two forms.

It attacks certain metals used in fuel systems, attacking whatever it touches until it is removed from your system. And when the water goes, the urea forms crystals that block filters and settle in tiny channels.

Pipes carrying AdBlue mean harm overnight for a vehicle sitting in Bilston. Only inside that tank, it stays stable.

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

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

Top up a diesel with petrol in error at the Costco, and this issue is thinned fuel.

Mixed into the diesel and left still, it is harmless at that stage; running your engine is the harm.

AdBlue in a diesel is a fault of the wrong substance altogether.

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

It does not stay mixed, and so it cannot be diluted. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than nearly anywhere else, whether the car is in Bush or the middle of Bilston.

As with petrol, there's good news.

Not run? Then the AdBlue waits just in that tank, the simplest section of the whole system to empty, anywhere your car has come to rest across Midlothian.

## How AdBlue ends up in a diesel tank around Bilston

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

Usually it's never the filling station: a driver buys a container driving home and pours it in at home.

Usually, it takes place in one of a few familiar ways.

Hurrying, outside the local primary school, after a warning lamp flashed on during the school run, someone refills the vehicle.

Close to Brookfield Terrace, a driver pours a container in on the drive after work.

Otherwise, in dim light outside the pub in the village, your vehicle is refilled by a driver opening that flap the first time.

It takes place most in the motors people know least: a hire car, a new motor, a company car, or the second motor of a household with one diesel and one petrol.

Wherever you are around Bilston or the rest of Midlothian, it is the same mistake and the same first answer: leave the vehicle off.

## Bilston: started the motor with AdBlue in the diesel tank?

Then the AdBlue has left the tank.

Your filter and pipework have had it pulled through, and some running takes it on to the high-pressure pump and each injector.

You may notice the engine running unevenly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Bilston Burn Park or halfway across Bilston.

Stop as soon as it is safe, switch off, and do not restart the vehicle to check.

More of that is pulled through with each start.

Leave the M8, under 10 miles from Bilston, by the next junction and stop somewhere safe, not carrying on.

How far it went matters. A few hundred yards across Bilston to the car park by Bilston Glen Colliery Memorial is a very different job from a run towards Edinburgh, under 10 miles away, with the AdBlue reaching further into the fuel system with every mile.

About how far it had come is worth telling us.

Once your engine has been started, the flush takes in more, and all of it is done where your car has ended up.

Caught quickly, it very rarely leaves long-term damage.

## Bilston: how AdBlue is emptied from a diesel

We come to the vehicle, wherever it has stopped in Bilston: a side street close to Bilston Parish Church, a drive, a lay-by or a forecourt.

The work rests on three answers, and our engineers get before all else — which fluid went in, the quantity, and if your engine has turned over.

The contaminated diesel and the urea leave together after that tank is emptied, right there.

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

Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested.

If your engine has not run, the majority of jobs take about half an hour once our engineers are there.

Our equipment is explosion-proof, so a live filling station is no issue, and it is hushed enough for a residential street after dark.

Fresh diesel goes in to bleed your system, and that's the final step.

You head off as soon as we have started the car, and it makes no difference whether your car is on a driveway in Bilston or in a bay outside Eskbank.

Before we go, our technicians make sure it's running smoothly with new diesel in.

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

Insurers want a VAT invoice and an engineer report, and you get both afterwards.

## About Bilston itself

Bilston is a village in Midlothian, situated on the riverside at an elevation of 163 metres, with semi-detached housing being the predominant type of accommodation. Bilston lies close to Edinburgh, Scotland's capital city, and is surrounded by other nearby places such as Seafield, New Pentland, and Old Pentland. Bilston has a population of approximately 1537 residents and is located about 5.7 miles from Edinburgh's city centre. Bilston is also relatively distant from London, being around 326.2 miles away.

## AdBlue drains across Midlothian, Bilston included

Throughout the EH postcode area, the teams answering AdBlue jobs around Bilston serve most of Midlothian too, Seafield, New Pentland and Old Pentland included.

Phone and ask instead of guessing if you are close to a border, or somewhere awkward to pin down.

No towing is needed. In Bilston, a village, a mobile service works: your vehicle is emptied where it stands, be it in a drive, a residential street, a parking area or a forecourt.

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

Because the jobs differ, a flat price wouldn't be fair.

Three things change the cost: whether the engine has run and for how long, how much AdBlue was put in, and where the car is. That last one rests on whether a van can reach it safely, and an open drive is easier than a tight gap behind Southside Free Baptist Church.

Which fluid got in, how much, plus if it ran: every Bilston call begins with precisely that, ahead of a quote, not after.

When they are answered, a range turns into a single fixed number.

You get that price on the phone, before anybody sets off, and you pay on the day, by card or over the phone, with nothing upfront.

Misfuelling cover comes with plenty of insurance policies, so it pays to look at yours before the van arrives.

## In Bilston and still next to your car?

Then, the best thing to do with the car is to leave it.

Keys out; engine and ignition off.

Phone 0333 366 0103 then tell us it is AdBlue, roughly how much, and whether it's run. Petrol in Diesel takes it from there, in Bilston or anywhere around Midlothian.
