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

Engine off, ignition off: that is where you begin if AdBlue has gone into the diesel tank.

AdBlue is urea dissolved in water.

The trouble starts once it's pulled through the lines — it will not burn, and it won't combine with diesel.

If the motor hasn't run yet, AdBlue in a diesel tank is generally emptied and thoroughly cleaned where the car sits in Bankside.

Nothing comes before calling 0333 366 0103.

## Bankside, AdBlue in your diesel tank: what to do at once

Things to do:

- So no one can turn your ignition on, take the keys away.

- Put the hazards on if you're anywhere near moving traffic.

- So you can give us which fluid it was and roughly what quantity, keep the receipt or the empty bottle.

- Call us from where you are. A postcode starting FK2 7, or the name of the closest street, brings the van to you without a search.

Things not to do:

- No starting your engine — not for a second, not to shift your car.

- The ignition remains off: on many diesels, switching it on is enough to start the pump.

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

- Do not drive the vehicle anywhere, not even a short distance up Castle Road.

- Do not try to drain it yourself by the roadside.

At a forecourt around Bankside, whether it is the Tesco or another one, ask the attendants to help you push the vehicle away from the pump.

If you are on your own drive, leave it just where it is.

## What AdBlue does in a diesel tank

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

Kept in a separate tank, it's squirted into the exhaust to treat the fumes.

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

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

Denser than diesel, it sinks and collects below it — the same place the pickup sucks from.

Easiest of all: one that had AdBlue in Grahamston overnight and hasn't turned since. The AdBlue waits at the base of your tank, untouched — but it will be the first thing through if the engine runs, before any diesel at all.

From there it causes two kinds of damage.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps labouring on the parts it reaches for as long as it stays there.

If the AdBlue has reached the pipework, leaving it overnight around Bankside leaves things worse. Inside that tank alone, waiting costs nothing.

Diesel lubricates the high-pressure pump and each injector as it flows; water gives none of that, and that is a second form of damage.

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

Fill a diesel with petrol in error over at the Thames, and the problem is diluted fuel.

Blended into your diesel and left unused, it's no threat for now; using your engine is the harm.

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

Not burning, it can't just be run through.

It does not stay mixed, and so it can't be thinned. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting the motor "to see" costs more here than nearly anywhere else, whether the vehicle is in Ladysmill or the middle of Bankside.

As with petrol, there is good news.

Never started? Then the AdBlue waits just in your tank, the simplest section of the whole system to empty, wherever the vehicle has stopped in Falkirk.

## AdBlue in a diesel tank around Bankside: how it ends up there

It is not on purpose. Plenty of cars keep the AdBlue cap beside the diesel one, occasionally under one flap, and muddling them up is simple in poor light.

Usually it is not the forecourt: a driver buys a bottle driving home and tips it in outside the house.

It tends to happen in a couple of familiar ways.

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

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

Else, after dark outside The Colonial, the vehicle is refilled by someone using that flap for the first time.

Hired cars, new cars, company cars, or the second vehicle in a family with one of each: the least known cars get it the most.

Wherever you are around Bankside or the remainder of Falkirk, it is the same mistake and the same first answer: leave it off.

## Started your engine with AdBlue in your diesel tank in Bankside?

Then the AdBlue has left the tank.

With any running time, it travels to the injection pump and each injector, after passing through the filter and lines.

Expect rough running, exhaust smoke, falling power, lights on your dash, or a stall — returning from Victoria Park, say, or midway across Bankside.

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

With each start, more of it is pulled through.

If you were on the M9, under a mile from Bankside, come off at the next exit and stop somewhere sensible rather than pressing on.

Distance matters: every mile pushes the AdBlue deeper in, and so driving for Stirling, under 10 miles away, gives a far larger job than hopping across Bankside to the car park by Air Thrill.

Roughly how far it had come is worth telling us.

Our technicians do all of the flushing where the vehicle has stopped, and once your engine has been started there is more of it.

Long-term damage is very uncommon if it is caught soon.

## Bankside: how AdBlue is emptied from a diesel

Wherever it has stopped around Bankside — a forecourt, a layby, a driveway, a road beside Keep Inspiring Change — the van travels to the car.

The job rests on three replies, and our technicians get before all else — what got in, the quantity, and whether the engine has run.

The contaminated diesel and the urea leave together when your tank is drained, right there.

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

Clean diesel goes in once your filter is flushed — or replaced, when it needs to be — and after that your vehicle is tested.

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

Quiet enough for use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.

Bleeding the fuel system with clean diesel comes at the end.

Whether it's a parking bay at Falkirk Grahamston or a drive around Bankside, that is where we start it and you head off.

The test before our engineers go is that it runs smoothly on fresh diesel.

No workshop is required at any point, with the entire job done on the spot.

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

## About Bankside and where it is

Bankside is a suburban area in Falkirk, situated near the coast at a low elevation of around 10 metres. Bankside lies within commuting distance of Stirling, which is approximately 9 miles away, and is close to other nearby places such as Langlees and Bainsford. Bankside has a population of around 4194 people, predominantly living in flats.

## AdBlue drains in Bankside and across Falkirk

Our teams that answer AdBlue calls around Bankside also cover the places round it, Langlees, Bainsford and Middlefield among them, and most of Falkirk beyond, across the FK postcode area.

If you're near a boundary, or somewhere hard to explain, ring and ask instead of assuming.

Bankside is a residential suburb, 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, so it never needs to be shifted to us.

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

Since each jobs vary, a single price wouldn't be fair.

Three things shift the cost: whether the motor has run and for how long, how much AdBlue got in, and where the car is. That last one turns on whether a technician can get to it safely, and an open drive is easier than a tight gap behind Dawson Community Centre.

Ahead of a quote, never afterwards, every enquiry from Bankside begins with the same three questions: the liquid, the quantity, plus whether it ran.

With those replies, the range shrinks to one fixed number.

Priced on the call before the engineer heads out, it is paid for that day — card or phone, no deposit.

Many insurance policies include misfuelling cover, and so it is worth checking yours whilst we're on the way.

## In Bankside and still beside the vehicle?

In that case, do nothing — that's the best step available.

Keys out, engine off, ignition off.

Petrol in Diesel takes over the remainder, across Bankside or anywhere within Falkirk, once you call 0333 366 0103 saying it was AdBlue, roughly how big an amount, and whether the engine ran.
