# AdBlue in a Diesel Tank in Simmondley? Don't Start It

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

In plain terms, AdBlue is simply urea in water.

Not like fuel, it neither burns nor mixes, and no harm happens till your motor sucks it through.

A drain and a thorough flush, done where your car is in Simmondley, is generally all AdBlue in a diesel tank needs — if it is caught before the engine has been run.

Phone 0333 366 0103 before you do anything else.

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

Do these:

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

- Near moving traffic? Then put the hazard lights on.

- Which fluid, and about what amount? Save the bottle or the receipt, and we can see.

- Call right where you are. Say a SK13 6 postcode or the nearest street sign, and no one has to search for you.

Never do these:

- Moving the vehicle even a few yards is no reason to fire up the motor.

- The ignition stays off: on many diesels, switching it on is enough to start your fuel pump.

- No more fuel added. The AdBlue won't mix, so it's wasted.

- Do not drive the vehicle anywhere, not even a short way along Storth Meadow Road.

- Do not try to drain the car yourself by the kerbside.

On a forecourt in Simmondley, whether it is the the nearest petrol station or another one, ask the staff to help you push the vehicle clear of the petrol pump.

Stopped on your own drive? Then it remains exactly where it is.

## AdBlue in a diesel tank, and what it does there

The engine is not what AdBlue is made for; your exhaust is.

From a separate tank it goes directly to your exhaust, cleaning what the engine emits.

A fuel pump is not designed to cope with it, and AdBlue was never supposed to travel through one.

Inside a diesel tank it acts very differently from fuel. It doesn't mix in.

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

Easiest of all: one that had AdBlue in Higher Gamesley overnight and has not turned since. The AdBlue sits at the foot of the tank, untouched — but it will be first through if the engine starts, ahead of any diesel at all.

From there it does two kinds of damage.

Crystals and corrosion. As the water evaporates, it leaves urea that hardens in filter elements and narrow passages; and, since it eats at certain metals, each part it touches suffers for as long as it stays inside.

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

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

## Why AdBlue in a diesel is frequently more serious than petrol

Top up a diesel with petrol by mistake at the Tesco, and this issue is diluted fuel.

It mixes with the diesel, and while it's in that tank it does no harm; the harm comes from running the motor on it.

The trouble with AdBlue in a diesel is a totally wrong liquid.

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

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

The same good news holds as with petrol.

Not started? Then the AdBlue waits just inside the tank, the simplest section of the entire system to empty, anywhere your car has come to rest in Derbyshire.

## How does AdBlue end up in a diesel tank in Simmondley?

Plenty of vehicles place the AdBlue cap alongside the diesel one, occasionally under one flap, and after dark the two may appear identical. Nobody intends it.

A bottle bought while heading home and poured in outside the house, instead of at the filling station, is the usual route.

Usually, it occurs in one of a couple of familiar ways.

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

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

Or your car is topped up in the car park at Hare & Hounds, in poor light, by a person who has never opened that flap before.

Rented cars, brand-new motors, fleet motors, or the spare car in a home with one of each: the least known cars see it the most.

Wherever across Derbyshire, Simmondley included, the slip doesn't change, and neither does the first response: keep it switched off.

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

The AdBlue has left the tank, then.

Your filter and lines have had it pulled through, and some running time takes it on to the high-pressure pump and each injector.

Expect rough running, exhaust smoke, falling power, warnings on your dash, or a stall — returning from Whiteley Nab, say, or part way across Simmondley.

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

With each start, more of it is pulled through.

On the M67, under 3 miles from Simmondley, the next junction is where to leave, and anywhere safe is where to stop — not driving on.

Each mile pushes the AdBlue deeper in. That's why crossing Simmondley to park beside Holy Trinity and a drive of under 15 miles for Manchester are very different jobs.

Roughly how far it had come is worth telling us.

Once the motor has been run, the flush covers more, and all of it is done where your car has ended up.

Noticed quickly, it very rarely leaves permanent damage.

## What clearing AdBlue from a diesel involves around Simmondley

Our technicians come to your car, wherever it has stopped around Simmondley: a side street near Charlesworth Independent Chapel, a drive, a lay-by or a forecourt.

The job depends on three answers, which our technicians ask for before all else — which fluid got in, the quantity, and whether your engine has turned over.

On the spot, your tank is then drained, and all of the contaminated diesel and the urea come out at once.

Your system is purged thoroughly, which matters more with AdBlue than with petrol, since what it leaves behind does not rinse out on its own.

A test of the car comes last, once clean diesel is added and the fuel filter is cleaned or, if needed, replaced.

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

Explosion-proof pumps mean a busy forecourt sensible to work on, and they run quiet enough not to disturb the neighbours at night.

The final step is to bleed the fuel system on clean diesel.

Whether it is a parking space by Dinting or a driveway around Simmondley, that is where we fire it up and you drive off.

Before leaving, our technicians confirm it's running correctly with new diesel in.

No garage is needed at any stage, with the entire job done then and there.

You receive a VAT invoice and an engineer report afterwards, which is what insurers ask for.

## About Simmondley, for a moment

Simmondley is a suburban area in Derbyshire, situated near the River Etherow and surrounded by nearby places such as Hobroyd, Hargate Hill, and Dinting Vale. Simmondley sits at an elevation of 184 metres, with a mix of housing types but predominantly detached homes. Simmondley is located close to Manchester, at a distance of 11.6 miles, and is approximately 154.3 miles from London. Simmondley has a population of around 3389 residents.

## Simmondley and Derbyshire: AdBlue drains across the area

AdBlue call-outs around Simmondley go to vans that cover the towns around it — Hobroyd, Hargate Hill as well as Dinting Vale — and much of Derbyshire further out, across SK postcodes.

Ring and ask rather than guess if you are by a county line, or anywhere awkward to pin down.

No moving is needed. In Simmondley, a residential suburb, a mobile service fits: the vehicle is drained where it stands, whether in a driveway, a residential street, a car park or a forecourt.

## What AdBlue in a diesel tank costs to put right around Simmondley

Each job is different, and so no single price would be honest.

Three things change the cost: whether your engine has been running and for how long, how much AdBlue was put in, and where the vehicle is. That last one turns on whether a technician can reach it safely, and an open driveway is simpler than a tight space behind St James.

Ahead of a quote, never after, each call from Simmondley opens with the same three checks: the fuel, the amount, and whether it ran.

Those answers shrink a range down to one number.

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

While our engineer is travelling, check your insurance: plenty include misfuelling.

## In Simmondley and still beside the car?

Then the most helpful thing you can do is nothing to your car.

Keys out, engine off, ignition off.

Petrol in Diesel takes over the remainder, across Simmondley or anywhere in Derbyshire, once you call 0333 366 0103 saying it was AdBlue, about how big an amount, and whether it ran.
