# AdBlue in the Diesel Tank in Upper Armley? Keep It Switched Off

AdBlue in your diesel tank? Then keep your engine off — and the ignition too.

Water with urea mixed in it: that is AdBlue.

The trouble starts once it is sucked through your pump — it will not ignite, and it won't combine with diesel.

Caught before the engine has been run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where your car is around Upper Armley.

Nothing comes before calling 0333 366 0103.

## Those opening minutes: AdBlue in your diesel tank in Upper Armley

Do these:

- Pocket your keys, and that stops anyone turning the electrics on.

- Put the hazards on if you are at all near moving traffic.

- The empty bottle or your receipt shows us the product and the amount, and so don't throw it out.

- The van finds you quickest with a postcode starting LS12 3, or just the name of a street nearby, and so phone from the spot.

Not to do:

- Not even briefly, and not to shift your vehicle: your motor remains off.

- The ignition stays off: on lots of diesels, turning it on is enough to start the fuel pump.

- Do not top up with diesel to dilute it. AdBlue doesn't mix in diesel; it separates out.

- Never drive the vehicle anywhere, not even a short way up Armley Ridge Road.

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

On a forecourt in Upper Armley, whether it's the BP or another one, ask the staff to help you push the vehicle away from the pump.

At home, your car stays exactly where it was left.

## What does AdBlue do in a diesel tank?

Not your engine but the exhaust is where AdBlue belongs.

From a separate tank it goes straight to your exhaust, treating what your engine lets out.

No part inside an injection pump is made for this liquid — and none of that was intended to go through one.

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

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

The first thing your fuel system pulls through, once it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Armley last night, and has not been started since, is still the straightforward case: the AdBlue is lying at the bottom of your tank, and nothing has pulled it in.

Two kinds of harm come from there.

Crystals and corrosion. As the water evaporates, it strands urea that hardens in filter elements and tiny passages; and, since it eats at some metals, each part it reaches keeps suffering for as long as it remains in there.

Where the AdBlue has reached the lines, leaving it overnight in Upper Armley makes things worse. Inside the tank only, waiting does nothing.

Diesel protects the high-pressure pump and each injector as it flows; water offers no lubrication, which is a second form of damage.

## AdBlue in a diesel: why it's commonly worse than petrol

Petrol pumped into a diesel on Shell's forecourt leaves the fuel watery — that's the main problem.

No harm comes while it sits unused, blended into your diesel — only when the motor runs on it.

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

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

It does not stay mixed, so it cannot be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting your engine "to see" costs more here than almost anywhere else, whether the car is in Upper Wortley or the middle of Upper Armley.

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

Emptying a tank is the easiest part on a fuel system, and without running, the AdBlue stays in it — anywhere in West Yorkshire the car has stopped.

## Upper Armley: how AdBlue ends up in a diesel tank

In dim light, two caps side by side — the AdBlue one and the diesel one, now and then behind a single flap — can look the same. No one intends it; many designs invite it.

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

The ways it takes place are few and familiar.

Rushing, outside Christ Church Upper Armley Church of England Primary School, after a warning lamp flashed on during the school run, a parent tops up your car.

After work, a container is tipped in on a driveway near Armley Grange Avenue.

Or the car is topped up in the car park at The Travellers Rest, in poor light, by someone who has never opened that flap before.

It occurs most in the motors motorists know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol.

Wherever you're around Upper Armley or the remainder of West Yorkshire, it's the same mistake and the same first answer: leave it off.

## AdBlue in the diesel tank around Upper Armley, and your engine started?

Then your tank is no longer where the AdBlue is.

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

You may notice your motor running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Gotts Park Rose Garden or halfway across Upper Armley.

When safe, stop and switch everything off — with no restarting to see.

More of that is pulled through with each start.

Leave the Inner Ring Road, under 3 miles from Upper Armley, by the next junction and stop safely, rather than driving on.

How far it went matters. A couple of hundred yards across Upper Armley to the car park by Armley Tennis Club is a very different job from a run towards Leeds, under 3 miles away, with the AdBlue reaching further into the system with every mile.

Roughly how far it had come is worth telling us.

Our technicians do all of the rinsing where the vehicle has come to a stop, and once your engine has been run there is more of it.

Caught early, it very rarely leaves lasting damage.

## Draining AdBlue in a diesel around Upper Armley: what it takes

We come to the vehicle, wherever it has stopped around Upper Armley: a side street near Christ Church, a drive, a lay-by or a forecourt.

The work depends on three answers, and we ask for before all else — which fluid went in, the quantity, and if the motor has turned over.

On the spot, your tank is then drained, and all of the polluted diesel and the urea leave as one.

A full flush counts far more after AdBlue than with petrol, since what remains won't clear away by itself.

Next, your filter: flushed, or replaced if it has to be. Then clean diesel, then a test of the vehicle.

If your engine has not run, the majority of jobs take about half an hour once our engineers are there.

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

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

Whether it is a parking space outside Headingley or a drive around Upper Armley, that is where our engineers start it and you set off.

The check before our technicians go is that it runs smoothly on fresh diesel.

No workshop is required at any point, with the whole job done then and there.

You get a VAT invoice and an engineer report after that, which is what insurers want.

## AdBlue drains across West Yorkshire, Upper Armley included

Carr Crofts, Gamble Hill and Silver Royd Hill are among the towns around Upper Armley that the same teams serve, along with much of West Yorkshire beyond, throughout the LS postcode area.

If you are close to a boundary, or somewhere hard to describe, ring and ask rather than guessing.

Anywhere your car sits — a driveway at home, a residential street, a parking area, a filling station — we drain it there, with no need to bring it to us; which suits Upper Armley, a residential suburb, well.

## Upper Armley: what AdBlue in a diesel tank costs to fix

There is no fair single price, because the jobs are not the same.

Three things change the cost: whether your engine has been running and for how long, how much AdBlue got in, and where the car is. That last one rests on whether a van can reach it safely, and an open drive is simpler than a tight spot behind Interplay.

For that in mind, each call from Upper Armley begins by asking the same trio — what was put in, how much, whether the engine ran — ahead of a figure.

The replies turn a range into a straight quote.

Priced by phone before the van sets out, it is settled on the day — card or phone, nothing in advance.

Check your insurance whilst we're on the way: many carry misfuelling cover.

## In Upper Armley and still next to the vehicle?

Right now, the best thing to do with the car is to not touch it.
