# Jocelyn Park: AdBlue in the Diesel Tank? Leave It Off

Engine off, ignition off: that's where you start if AdBlue has gone into your diesel tank.

Urea mixed in water is what AdBlue is.

The harm begins once it is sucked through the lines — it will not ignite, and it won't combine with diesel.

A drain and a thorough flush, done where the vehicle is in Jocelyn Park, is generally all AdBlue in a diesel tank takes — if it's caught before the motor has run.

No step comes before ringing 0333 366 0103.

## Those opening minutes: AdBlue in the diesel tank around Jocelyn Park

Do:

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

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

- The empty bottle or your receipt tells us the fluid and the amount, so don't throw it away.

- Ring us from where you are. A postcode starting TA20 2, or the name of the closest street, brings our van to you without a search.

Don't do these:

- Don't start the engine, even for a moment to shift your car.

- Plenty of diesels power their fuel pump the moment the ignition goes on, and so keep the vehicle off.

- Adding extra diesel does not work: AdBlue settles out instead of blending.

- Leave it where it is rather than driving it anywhere, even a short way along Forton Road.

- Don't try to drain the vehicle yourself by the kerbside.

At a forecourt around Jocelyn Park, whether it's the Texaco or another one, ask the attendants to help you roll your car away from the pump.

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

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

AdBlue is made for your exhaust, not the motor.

Kept in a separate tank, it's squirted into the exhaust to treat the gases.

Neither side suits the other: urea doesn't belong in an injection pump, and an injection pump can't take urea.

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

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

The first thing the system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Crimchard last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has pulled it in.

It does two kinds of damage from there.

Crystals and corrosion. As the water evaporates, it leaves urea that crystallises in filter elements and tiny channels; and, because it eats at certain metals, each part it reaches suffers for as long as it stays in there.

If the AdBlue has reached the lines, leaving it till morning around Jocelyn Park makes things worse. In that tank alone, time costs nothing.

Water protects nothing. The injection pump and every injector depend on diesel flowing past them, and so the water content damages them in its own right.

## Petrol or AdBlue in a diesel: why AdBlue is regularly worse

Petrol put into a diesel on Tesco's forecourt makes the fuel watery — that is the main fault.

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

AdBlue in a diesel is a fault of the wrong substance altogether.

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

Whether the car sits in Forton or the centre of Jocelyn Park, turning it over "to see" costs more in this case than almost any other error, and the flush matters for more. Why: it won't remain mixed, and so diluting it is impossible; and deposits and corrosion outlast the next fill.

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

Clearing a tank is the easiest job on a fuel system, and with no running, the AdBlue remains in there — wherever across Somerset the vehicle sits.

## Jocelyn Park: how AdBlue ends up in a diesel tank

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

A bottle picked up while driving home and poured in outside the house, rather than at the filling station, is the usual route.

A couple of familiar ways account for most cases.

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

Near Ken Close, a driver tips a bottle in on that drive after work.

Or someone unfamiliar with that flap tops up your car after dark, stopped in the car park outside The King's Head.

It crops up most in a rental, a new vehicle, a fleet motor, or the other car of a family with one of each fuels — the cars drivers use least.

An identical slip, an identical first response — keep it off — wherever you happen to be in Jocelyn Park or the remainder of Somerset.

## Already started your engine with AdBlue in your diesel tank around Jocelyn Park?

Then the AdBlue has left your tank.

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

You may see the engine running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Snowdon Park or halfway across Jocelyn Park.

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

More of that is pulled through with each start.

Jocelyn Park sits under 15 miles from the M5; if you were on it, leave at the first junction and stop somewhere safe instead of driving on.

Every mile pushes the AdBlue deeper in. That is why crossing Jocelyn Park to park near St Mary's and a drive of under 50 miles for Exeter are such separate jobs.

About how far it had come is worth telling us.

Wherever your car came to a stop is where all of it gets done, even with more to flush once your engine has been run.

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

## Emptying AdBlue in a diesel around Jocelyn Park: what it takes

Wherever it has stopped in Jocelyn Park — a forecourt, a layby, a driveway, a street by Chard Methodist Church — the van comes to your vehicle.

The job rests on three answers, which our technicians get before all else — which fluid was put in, the amount, and if the engine has run.

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

With AdBlue, far more than with petrol, flushing counts: the fuel system is flushed right through since residue won't wash away unaided.

Testing the vehicle comes last, once fresh diesel goes in and the filter is cleaned or, if necessary, replaced.

The majority of these jobs are a half-hour job once our engineers turn up, if your motor hasn't run.

Quiet enough for use outside a house at night, and safe on a working forecourt, our pumps are explosion-proof.

The final step is to prime your system on clean diesel.

At that point our engineers fire it up and you drive off, whether from a parking space outside Axminster or a drive in Jocelyn Park.

Our engineers check it runs correctly on new diesel before we go.

Our engineers do it all wherever your car has ended up, and it never has to go to a garage.

The insurer will want an engineer's report and the VAT invoice — both yours afterwards.

## About Jocelyn Park and where it is

Jocelyn Park is a suburban area in Somerset, situated inland at an elevation of 111 metres, and is located near the towns of Chard and Holbear. Jocelyn Park is characterized by its predominantly semi-detached housing stock, which reflects the typical residential development of the South West region. Jocelyn Park sits approximately 26.9 miles from Exeter and 130.4 miles from London, making it a relatively remote suburban community.

## AdBlue drains across Jocelyn Park and Somerset

AdBlue call-outs in Jocelyn Park go to teams that serve the towns around it — Holbear, Chard as well as Furnham — and most of Somerset further out, across TA postcodes.

Guessing doesn't help by a border or anywhere tricky to describe; phone and ask.

Jocelyn Park is a residential suburb, and an on-site drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it stands, and so it never needs to be moved to us.

## What does AdBlue in a diesel tank cost to sort out in Jocelyn Park?

Because each jobs differ, a flat price wouldn't be fair.

Whether the motor has been running, and for how long, comes first in what moves the cost. How much AdBlue went in comes next, and then the position of the vehicle, because an open drive is simpler for our van to reach safely than a tight spot behind Chard Baptist Church.

That's why each call from Jocelyn Park starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and if it's run.

When those are answered, a range becomes one firm figure.

You hear that quote on the phone, before anyone 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 cover misfuelling.

## Jocelyn Park: still next to the car?

Then, touch nothing — that is the best step there is.

Ignition off, engine off, keys out.

Petrol in Diesel handles the remainder, in Jocelyn Park or wherever in Somerset, after you call 0333 366 0103 to say it's AdBlue, about what quantity, and if the engine ran.
