# AdBlue in the Diesel Tank in Hobroyd? Keep It Switched Off

If AdBlue has gone into the diesel tank, keep the engine off then leave the ignition off.

In plain terms, AdBlue is simply urea in water.

It does not burn, it does not mix with diesel, and the harm it does starts when the fuel system draws it in.

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

Call 0333 366 0103 before you do anything else.

## Those opening minutes: AdBlue in your diesel tank in Hobroyd

To do:

- So nobody can turn your ignition on, pull your keys out.

- Hazards on, if moving traffic is anywhere near.

- So you can tell us which liquid it was and roughly how much, keep the till receipt or the empty bottle.

- Call right where you are. Say a SK13 6 postcode or the nearest street name, and nobody has to search for you.

Never do these:

- Not even for a second, and not to roll the vehicle: the engine stays off.

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

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

- Any driving at all is best avoided, including a short way along Longmoor Road.

- Draining your tank yourself by the road is not worth trying.

Ask the people behind the counter to help you move the vehicle away from the pumps if you're on a forecourt in Hobroyd, whether it is the the nearest petrol station or somewhere else.

If you are on your own drive, leave the car just where it sits.

## AdBlue in a diesel tank: what it does

Meant for the exhaust, AdBlue has no business in your motor.

It goes into its own tank and is sprayed into your exhaust gas to clean it.

Neither side suits the other: urea does not belong in a pump, and a pump cannot deal with urea.

It does not blend. After it is tipped into the tank, AdBlue behaves nothing like fuel.

Denser than diesel, it drops and collects below it — the same place the intake draws from.

A motor filled on a drive in Whitfield Park overnight and left unstarted is the straightforward one. Nothing has sucked the AdBlue up so far — though once the motor turns, that is what goes first, directly from the bottom of your tank.

From there it causes two kinds of harm.

Crystals and corrosion. As the water dries, it leaves urea that crystallises in filter elements and tiny passages; meanwhile, because it attacks some metals, each part it reaches suffers for as long as it remains inside.

A motor left sitting around Hobroyd with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not.

Diesel lubricates the injection pump and each injector as it flows; water offers no lubrication, and that is a separate kind of harm.

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

A fault of thin fuel is what you end up with after filling a diesel with petrol at the Tesco.

No damage comes as long as it stays unused, mixed into the diesel — only when the engine works on it.

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

It doesn't burn, and so it can't simply be run through.

It doesn't stay mixed, so it cannot be weakened. 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 your motor "to see" costs more here than nearly anywhere else, whether the vehicle is in Hargate Hill or the middle of Hobroyd.

The good news is the same as with petrol.

Wherever around Derbyshire your vehicle has stopped, an unstarted engine means the AdBlue still in the reservoir: the simplest part of a fuel system to empty.

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

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

Most of the time it happens with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

It tends to happen in a few familiar ways.

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

Someone pours the container in at home, just off Simmondley New Road, as the day ends.

Else, in dim light by Hare & Hounds, the car is refilled by someone using that flap for the first time.

Rented motors, brand-new vehicles, company motors, or the spare vehicle in a family with both fuels: the least known cars get it the most.

Keep it switched off: that is the first response to the same slip, wherever in Hobroyd or the rest of Derbyshire you happen to be.

## Started your engine with AdBlue in your diesel tank around Hobroyd?

Then the AdBlue has left that tank.

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

Expect rough running, smoke, falling power, warnings on your dash, or a stall — returning from Harehills Park, say, or part way across Hobroyd.

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

Each start pulls more of it through.

On the M67, under 3 miles from Hobroyd, the next junction is where to exit, and anywhere sensible is where to stop — not carrying on.

Each mile pushes the AdBlue further into the system. That's why crossing Hobroyd to park beside St James and a drive of under 15 miles for Manchester are such distinct jobs.

Let us know roughly how far it had come.

Our engineers do all of the cleaning where the car has stopped, and once the engine has been run there is more of it.

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

## What does an AdBlue drain on a diesel involve in Hobroyd?

The vehicle remains where it is, whether that's a road beside The Vineyard, a drive, a layby or a forecourt around Hobroyd, and our van comes to it.

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

Next, draining your tank right there takes out the contaminated diesel and the AdBlue in one go.

With AdBlue, more so than with petrol, the flush matters: the whole system is cleaned right through since residue won't flush out unaided.

After that, your filter: flushed, or replaced if it must be. After that clean diesel, then a check of your car.

Roughly half an hour once we arrive is typical for most jobs when the engine has not run.

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

Fresh diesel goes in to prime the fuel system, and that is the final step.

After that our engineers fire it up and you set off, whether from a parking bay outside Glossop or a drive around Hobroyd.

It's checked on clean diesel to confirm it runs smoothly before our engineers leave.

As the job is done in its entirety where the vehicle is, a workshop never comes into it.

You get a VAT invoice and an engineer report later on, which is what insurers ask for.

Guessing doesn't help by a county line or somewhere tricky to pin down; ring and check.

Hobroyd is a small village, and an on-site drain suits it: whether the car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it sits, so it never needs to be moved to us.

## What does AdBlue in a diesel tank cost to sort out around Hobroyd?

Because each jobs vary, a single price would not be fair.

Whether the motor has been running, and for how long, comes first in what changes the cost. How much AdBlue got in comes next, and then the position of your car, because an open driveway is easier for a van to get to safely than a tight gap behind Holy Trinity.

Before a quote, not after, each enquiry from Hobroyd begins with three checks: the fuel, the quantity, and whether it ran.

The answers turn a range into a straight quote.

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.

Look at your insurance while we are on the way: plenty carry misfuelling cover.

## Hobroyd: still alongside the car?

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

Keys out, motor off, ignition off.

Call 0333 366 0103 and tell us it's AdBlue, about how much, and whether it has run. Petrol in Diesel takes it from there, in Hobroyd or anywhere around Derbyshire.
