# Don't Start It: AdBlue in a Diesel Tank in Yardley Gobion

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

AdBlue is urea mixed in water.

It doesn't burn, it doesn't mix with diesel, and the harm it does begins when your fuel system pulls it in.

In Yardley Gobion, AdBlue in a diesel tank caught before your engine runs normally comes down to a drain and a thorough flush, just where the vehicle is.

Before you do anything else, call 0333 366 0103.

## Yardley Gobion, AdBlue in your diesel tank: what to do straight away

Do these:

- Pocket your keys, which prevents someone turning the power on.

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

- So you can tell us which fluid it was and about what quantity, save the receipt or the empty bottle.

- Our van finds you fastest with a postcode starting NN12 7, or simply the name of a street nearby, and so phone from the spot.

Not to do:

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

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

- No more fuel on top. The AdBlue won't blend, and so it is wasted.

- Leave the vehicle where it is instead of driving it anywhere, even a short way up Moorend Road.

- By the road, do not attempt emptying it yourself.

On a forecourt around Yardley Gobion, whether it's the BP or another one, ask the attendants to help you push the car away from the petrol pump.

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

## AdBlue in a diesel tank: what it does

AdBlue is made for your exhaust, not your engine.

From a separate tank it goes straight to the exhaust, treating what your engine emits.

Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

Tipped in with your diesel, it keeps separate rather than blending — entirely different from fuel.

It's heavier than diesel, and so it sinks and collects at the bottom of the tank, which is where the pickup pulls fuel from.

Simplest of all: a vehicle that got AdBlue in Grafton Regis last night and has not turned since. The liquid sits at the foot of the tank, untouched — but it would be the first thing through once the motor runs, ahead of any diesel at all.

From there it causes two kinds of damage.

Crystals and corrosion. As the water evaporates, it strands urea that hardens in filter elements and tiny channels; meanwhile, because it eats at certain metals, every part it touches suffers for as long as it stays inside.

Pipes carrying AdBlue spell damage by morning for a car parked around Yardley Gobion. Only in that tank, it stays stable.

Diesel protects the injection pump and every injector as it passes; water offers none of that, which is a second form of damage.

## AdBlue in a diesel: why it's regularly worse than petrol

An issue of thinned fuel is what you get from filling a diesel with petrol at the Esso.

No harm comes while it stays put, blended into your diesel — only when your motor runs on it.

With AdBlue in a diesel, the fluid as such is simply the wrong one.

Since it does not burn, running it through is not an option.

Nor can it be thinned, because it splits back out — and the following fill will not clear away deposits or corrosion. So the flush matters more here, and turning the key "to see", in the centre of Yardley Gobion or out in Alderton, costs more than almost any other mistake.

With AdBlue, the good news is no distinct from petrol.

Wherever around Northamptonshire the car has stopped, an unstarted engine leaves the AdBlue still inside the reservoir: the simplest part of a fuel system to clear.

## How does AdBlue end up in a diesel tank around Yardley Gobion?

No one means to do it. The AdBlue filler on many cars sits right next to your diesel filler, sometimes under the same flap, and the two caps can look alike in poor light.

It mostly happens outside the house, from a bottle bought en route home, rather than at the forecourt.

The ways it happens are few and familiar.

Midway through the drop-off, the dashboard warns, and outside Yardley Gobion Church of England Primary School the refill is hurried.

Someone tips the container in outside their house, just off Grafton Road, as the day ends.

Or the car is topped up in the car park at Coffee Pot Tavern, in poor light, by a person who has never opened that flap before.

Rented motors, new vehicles, company cars, or the spare vehicle in a home with both fuels: the least familiar cars see it most.

Wherever you are in Yardley Gobion or the rest of Northamptonshire, it's the same mistake and the same first answer: leave the car off.

## Already started the engine with AdBlue in the diesel tank in Yardley Gobion?

Then your tank is no longer where the AdBlue is.

It's been pulled through your filter and the lines, and if your motor ran for any time, it has reached your high-pressure pump and your injectors.

Lumpy running, smoke, lost power, dashboard lights or stalling: each may show up, perhaps midway across Yardley Gobion or coming back from Fiery Furze.

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

Every start pulls more of it through.

If you were on the M1, under 5 miles from Yardley Gobion, come off at the next exit and stop somewhere safe instead of pressing on.

Hopping across Yardley Gobion to the car park by Saint Leonard's Church is one thing; heading for Milton Keynes, under 10 miles away, is another, since every mile carries the AdBlue deeper in. So distance matters.

Tell us about how far it had come.

Once the engine has been started, the flush covers more, and all of it is done where your car has come to a stop.

Very seldom does it leave permanent damage if it's spotted early.

## Yardley Gobion: how AdBlue is cleared from a diesel

The vehicle remains where it is, whether that is a road beside Yardley Gobion United Reformed Church, a drive, a layby or a filling station in Yardley Gobion, and the van travels to it.

Three replies decide the job, so before anything else our engineers ask which fluid went in, roughly the amount, and whether your motor has run.

Next, draining the tank right there takes out the contaminated diesel along with the AdBlue together.

A careful flush counts far more with AdBlue than with petrol, since what remains will not wash away by itself.

A test of your vehicle comes at the end, once clean diesel is added and the fuel filter gets flushed or, if needed, replaced.

If the motor hasn't run, most jobs take about half an hour once our engineers are there.

The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house after dark.

Bleeding the fuel system with fresh diesel comes last.

You drive off as soon as our technicians have started the car, and it makes no difference whether the vehicle is on a driveway around Yardley Gobion or in a space outside Wolverton.

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

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

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

## AdBlue in a diesel tank in Yardley Gobion: the cost of fixing it

Since each callouts vary, a single figure would not be fair.

What shifts the price is, firstly, whether the motor has run and for how long; then how much AdBlue went in; and finally where the vehicle is and whether our van can reach it safely, which is easier on an open driveway than in a tight space behind Yardley Gobion Children Centre.

With that reason, each enquiry from Yardley Gobion opens by asking the identical trio — which fluid got in, how much, if the engine ran — before any quote.

The answers turn a range into a straight quote.

The quote is quoted during the call, before a van leaves; payment happens on the day, by card or by phone, with nothing upfront.

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