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

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

AdBlue is urea dissolved in water.

The trouble starts once it's pulled through the pump — it will not ignite, and it won't blend with diesel.

If the motor hasn't run yet, AdBlue in a diesel tank is normally drained and carefully flushed where the vehicle sits around Brecks.

Ring 0333 366 0103 before you do anything else.

## Your next steps right now, Brecks: AdBlue in your diesel tank

Things to do:

- Remove the keys, and that stops anyone switching the power on.

- Hazards on, if moving traffic is at all close.

- Which fluid, and roughly how much amount? Save the bottle or the till receipt, and our technicians will know.

- Ring just where you are. Quote a S65 3 postcode or the closest street name, and nobody has to hunt for you.

Not to do:

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

- Don't switch the ignition on. On many diesels that alone runs the fuel pump.

- No extra fuel on top. The AdBlue won't mix, and so it's wasted.

- Never drive it anywhere, not even a short stretch along Brecks Crescent.

- Do not try to drain the vehicle yourself at the roadside.

On a forecourt around Brecks, whether it is the Texaco or another one, ask the attendants to help you roll the car away from the pump.

If you're on your own drive, leave the car exactly where it is.

## AdBlue in a diesel tank: what it does

Meant for your exhaust, AdBlue has no place in your engine.

Its own reservoir keeps it, and from there it's fed into the exhaust, and there it treats the gas.

No part inside an injection pump is made for this fluid — and no part of it was intended to travel that way.

It doesn't combine. Once it is poured into the tank, AdBlue behaves not at all like fuel.

The intake sucks fuel from the deepest part of that tank, and that's just where AdBlue settles: being denser than diesel, it sinks.

A vehicle topped up on a drive in Herringthorpe overnight and left unstarted is the straightforward case. No pump has pulled the AdBlue up so far — but when your motor runs, that is what goes first, straight from the bottom of the tank.

It causes two kinds of damage from there.

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

Where the AdBlue has reached the lines, leaving it overnight in Brecks leaves things worse. Inside the tank only, time costs nothing.

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

## Why AdBlue in a diesel is commonly more major than petrol

Fill a diesel with petrol by mistake at the Esso Tesco Fuel Station, and this problem is thinned fuel.

Blended through your diesel and sitting still, it is no threat at that stage; using the engine does the damage.

AdBlue in a diesel is an issue of the wrong substance altogether.

It cannot just be run through, since it doesn't burn.

Nor can it be thinned, since it separates again — and the next tankful will not clear away deposits or corrosion. So the flush counts for more here, and trying the engine "to see", in the heart of Brecks or out in Flanderwell, does more harm than nearly any other error.

As with petrol, there's good news.

Not run? Then the AdBlue waits only in your tank, the simplest section of the entire system to empty, anywhere your car has come to rest across South Yorkshire.

## Brecks: how AdBlue ends up in a diesel tank

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

A container bought when driving home and tipped in at home, instead of at the forecourt, is the usual route.

It tends to take place in a few familiar ways.

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

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

Or the car is topped up in the car park at The Stag, 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 company car, or the other vehicle of a home with both fuel types — the cars people know least.

Wherever across South Yorkshire, Brecks included, the slip doesn't change, and nor does the first step: keep it switched off.

## AdBlue in your diesel tank around Brecks, and the motor started?

The AdBlue has left the tank, then.

The filter and pipework have had it pulled through, and any running time takes it on to the injection pump and every injector.

Perhaps coming back from Gibbing Greave Wood, or part way across Brecks, your motor may run lumpy, smoke, lose pace, light up the dash or cut out.

When you safely can, pull over and switch everything off — with no restarting to see.

Each start pulls more of it through.

If you were on the M1, under 3 miles from Brecks, come off at the next junction and stop somewhere sensible instead of pressing on.

A quick hop across Brecks to the car park by St Cuthbert is one thing; heading for Sheffield, under 10 miles away, is something else, because each mile pushes the AdBlue deeper in. So mileage counts.

About how far it had come is worth telling us.

Wherever the car came to a halt is where all of it gets done, even with more to flush after the motor has been running.

Very seldom does it leave lasting damage if it is noticed quickly.

## Brecks: how AdBlue is emptied from a diesel

A road by Herringthorpe United Reformed Church, a driveway, a lay-by or a filling station: wherever the car has come to rest around Brecks, our engineers come to it.

What was put in, about the quantity, plus if the motor has been run: we ask before all else, since those decide the job.

The polluted diesel and the urea leave together after that tank is emptied, on the spot.

Residue from AdBlue won't flush out by itself, so the fuel system gets a full flush, which matters much more here than for petrol.

Next, the filter: flushed, or changed when it must be. After that fresh diesel, and then a check of the vehicle.

If your motor has not run, most jobs take about half an hour once our engineers are there.

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

Last, the fuel system is bled with new diesel.

Firing it up comes next, and then you set off from where your car is parked, at Rotherham Central or on a drive around Brecks.

Before we go, we make sure it's running smoothly with fresh diesel in.

As the job is done in its entirety where your car is, a garage never comes into it.

Afterwards, you are given paperwork for your insurer: a VAT invoice plus a written report from the engineer.

## Brecks and South Yorkshire: AdBlue drains across the area

Throughout the S postcode area, the vans answering AdBlue jobs around Brecks reach most of South Yorkshire too, Listerdale, Dalton Magna and Church Field among them.

Close to a boundary, or somewhere awkward to pin down? Checking beats guessing, and so ring.

Wherever the vehicle stands — your drive at home, a side street, a car park, a forecourt — our engineers drain it on the spot, and there's no need to take it to us; that suits Brecks, a village, well.

## AdBlue in a diesel tank around Brecks: the cost of fixing it

Since each jobs differ, a single figure wouldn't be fair.

Three things change the cost: whether the motor has run and for how long, how much AdBlue went in, and where your car is. That last one rests on whether a technician can reach it safely, and an open drive is simpler than a tight gap behind Swinburne Place Neighbourhood Centre.

That is why every call from Brecks starts with the same three questions, asked before giving a figure, not after: what got in, how much, and whether it has run.

Those answers narrow a range right down to one number.

You get that quote on the phone, before anyone heads out, and you pay on the day, by card or by phone, with nothing upfront.

Misfuelling cover is part of many insurance policies, so it pays to look at yours before the van gets there.

## Brecks: still next to your car?

Then, touch nothing — that's the most helpful step there is.

Keys out; motor and ignition off.

Petrol in Diesel handles the rest, in Brecks or wherever in South Yorkshire, after you call 0333 366 0103 to say it was AdBlue, roughly how big an amount, and whether the engine ran.
