# AdBlue in a Diesel Tank in Sutton on Sea? Don't Start It

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

Water with urea dissolved in it: that's AdBlue.

Unlike fuel, it neither burns nor blends, and nothing happens until the engine sucks it through.

In Sutton on Sea, AdBlue in a diesel tank caught before the motor runs usually comes down to a drain and a thorough flush, right where the car is.

Before you do anything else, phone 0333 366 0103.

## AdBlue in the diesel tank around Sutton on Sea: the first few minutes

To do:

- Remove your keys, and that stops someone turning the electrics on.

- Near moving traffic? So put the hazards on.

- The empty bottle or the receipt shows us the fluid and the amount, and so do not throw it away.

- Call us from where you are. A postcode starting LN12 2, or the name of the nearest street, brings the van to you without a search.

Not to do:

- No starting your engine — not briefly, not to shift the vehicle.

- Plenty of diesels power their fuel pump the instant the ignition comes on, so keep it off.

- AdBlue doesn't dilute in diesel — it separates out — so adding extra fuel won't thin it.

- Even a short way along High Street is too far to drive it.

- Don't try to drain the car yourself at the kerbside.

Ask the people behind the counter to help you roll your vehicle off the island if you're on a forecourt around Sutton on Sea, whether it's the J.D Birch or elsewhere.

If you're on your own drive, leave it precisely where it sits.

## What AdBlue does in a diesel tank

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

From a separate reservoir it goes straight to your exhaust, treating what the motor emits.

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

Tipped in with your diesel, it stays apart instead of mixing — quite unlike fuel.

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

A car filled on a driveway in Thorpe overnight and left unstarted is the straightforward one. No pump has pulled the AdBlue up yet — but when the engine turns, that's what is pulled first, straight from the bottom of that tank.

Two kinds of damage come from there.

Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filters and tiny passages; and, because it eats at some metals, each part it touches suffers for as long as it remains in there.

Pipes holding AdBlue spell harm by morning for a vehicle parked in Sutton on Sea. Just in that tank, it stays the same.

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

## Why is AdBlue in a diesel regularly the bigger issue?

Petrol put into a diesel on Empire Garage's forecourt makes the fuel thin — that's the whole fault.

No harm is done as long as it stays unused, mixed into your diesel — only when your motor runs on it.

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

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

Crystals and corrosion remain after the following fill, and AdBlue splits again out of the diesel, so thinning it won't work. That is why the flush counts more, and trying your engine "to see" does more harm here than nearly any other mistake — in Mablethorpe or the heart of Sutton on Sea equally.

The good news is the same as with petrol.

Anywhere around Lincolnshire your vehicle has stopped, an unrun motor leaves the AdBlue still in the tank: the easiest bit of a fuel system to empty.

## AdBlue in a diesel tank in Sutton on Sea: how it ends up there

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

It usually happens at home, from a container grabbed en route home, not at the forecourt.

It tends to occur in a few familiar ways.

The refill is hurried outside Sutton-on-Sea Community Primary School, after your dash lit up with a warning as the children were taken off.

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

Or your car is topped up in the car park outside Bacchus Hotel, in poor light, by someone who has never opened that flap before.

It crops up the most in a rental, a brand-new car, a fleet vehicle, or the other car of a family with one of each fuel types — the vehicles drivers know the least.

Wherever around Lincolnshire, Sutton on Sea as well, the mistake does not change, and nor does the first step: leave it off.

## Sutton on Sea: started the motor with AdBlue in your diesel tank?

The AdBlue has left that tank, then.

The filter and pipework have had it sucked through, and any running takes it on to the high-pressure pump and every injector.

Watch for lumpy running, exhaust smoke, lost power, lights on your dash, or a stall — returning from Meridale Community Garden, perhaps, or midway across Sutton on Sea.

Pull over when it is safe. Turn off. Leave the car off rather than restarting it to check.

Each start pulls more of that through.

Leave the M180, under 50 miles from Sutton on Sea, at the next junction and park somewhere safe, not carrying on.

How far it went matters. A few hundred yards across Sutton on Sea to the car park by Martin Robertson memorial bench is a very different job from a run towards Lincoln, under 50 miles away, with the AdBlue reaching further into the fuel system with every mile.

About how far it had come is worth telling us.

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

When it's noticed soon, lasting damage is very unusual.

## What emptying AdBlue from a diesel involves around Sutton on Sea

Our engineers come to the vehicle, wherever it has stopped in Sutton on Sea: a side street close to If, a drive, a lay-by or a forecourt.

Three replies decide the work, so before anything else our technicians ask what went in, roughly what quantity, plus if your motor has turned over.

Then the tank is drained where the vehicle stands, so the contaminated fuel and the AdBlue come out together.

A full flush matters much more after AdBlue than after petrol, because residue won't clear out on its own.

Next, your filter: flushed, or changed when it has to be. Then clean diesel, and then a test of your car.

Roughly half an hour once we arrive is typical for most jobs when your engine hasn't run.

The equipment is explosion-proof, and so a busy forecourt is no issue, and it's quiet enough for a residential street after dark.

Lastly, the system is primed with fresh diesel.

Whether it's a parking space by Skegness or a drive in Sutton on Sea, that is where our engineers fire it up and you set off.

The check before we leave is that it runs properly on new diesel.

The entire job is done where your car is, so it never needs to be taken to a workshop.

At the end, you are given paperwork for the insurer: a VAT invoice and a written report from the engineer.

## What does AdBlue in a diesel tank cost to sort out around Sutton on Sea?

Each job differs, so no fixed price is honest.

What moves the cost is, firstly, whether the engine has run and for how long; then how much AdBlue got in; and finally where the car is and whether a technician can reach it safely, which is simpler on an open driveway than in a tight spot behind Meridale Youth and Community Centre.

Which fluid went in, how much, plus whether the engine ran: every Sutton on Sea enquiry opens with exactly that, before any quote, never afterwards.

Their replies narrow the range right down to one figure.

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

As our engineer is on the way, dig out your policy: many include misfuelling.
