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

AdBlue in the diesel tank? Then leave the motor off — and the ignition as well.

Chemically, AdBlue is simply urea in water.

It doesn't burn, it doesn't mix with diesel, and the damage it does starts when your fuel system pulls it in.

If your engine hasn't run yet, AdBlue in a diesel tank is usually emptied and carefully rinsed where the car sits in Great Lumley.

First, phone us on 0333 366 0103.

## Those opening minutes: AdBlue in your diesel tank in Great Lumley

Things to do:

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

- Put your hazards on if you are at all close to moving traffic.

- Which fluid, and about how much amount? Hang on to the bottle or your receipt, and our technicians can know.

- The van locates you fastest with a postcode starting DH3 4, or simply the name of a street nearby, and so phone from the car.

Not to do:

- Not even briefly, and not to roll your car: the engine remains off.

- Your ignition stays off: on lots of diesels, switching it on is enough to run the fuel pump.

- Don't top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.

- Do not drive it anywhere, not even a short stretch along Scott Court.

- No emptying it yourself, at all, at the roadside.

Get the people behind the counter to help you move the vehicle off the pumps if you're at a forecourt around Great Lumley, whether it's the JET or somewhere else.

Parked on your own driveway? Then it stays exactly where it is.

## What AdBlue does in a diesel tank

Meant for the exhaust, AdBlue has no business in the engine.

Its own tank keeps it, and from there it is sprayed into your exhaust, and there it cleans the fumes.

A fuel pump is not made to take it, and AdBlue was never intended to go through one.

It doesn't combine. After it is tipped into a tank of diesel, AdBlue behaves nothing like diesel.

It's heavier than diesel, and so it sinks and collects at the bottom of that tank, which is where the pickup pulls 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 Bournmoor last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of your tank, and nothing has pulled it in.

Once it's sucked in, the damage takes two forms.

It eats at some metals found in fuel systems, working on whatever it reaches till it is cleared from your system. And when the water evaporates, the urea forms crystals that block filters and lodge in tiny channels.

Lines holding AdBlue mean damage by morning for a vehicle sitting around Great Lumley. Only inside that tank, it stays stable.

Diesel lubricates the injection pump and every injector as it passes; water offers none of that, and that is a separate kind of harm.

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

A fault of thinned fuel is what you get from fuelling a diesel with petrol at the Esso.

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

The trouble with AdBlue in a diesel is a completely unsuitable liquid.

It does not burn, so it can't simply be run through.

Deposits and corrosion stay through the next fill, and AdBlue separates back from your diesel, and so thinning it won't work. That is why the flush matters so much, and turning your key "to see" does more harm here than nearly any other mistake — in Fence Houses or the heart of Great Lumley equally.

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

Never started? Then the AdBlue sits only inside your tank, the simplest section of the entire system to clear, wherever the vehicle has stopped around Durham.

## AdBlue in a diesel tank around Great Lumley: how it ends up there

After dark, two caps together — the AdBlue cap and the diesel cap, occasionally under a single flap — may appear the same. No one means it; many layouts allow it.

It usually takes place at home, from a container grabbed on the journey home, not at the filling station.

It tends to take place in a few familiar ways.

A warning light comes on during the school run, and the top-up occurs in a hurry outside Lumley Junior School.

In the evening, a container is tipped in on a driveway near Churchside.

Else, in dim light outside The Old England, the car is refilled by someone using that flap for the first time.

It comes up most in a rental, a brand-new vehicle, a fleet car, or the spare motor in a family with both fuel types — the cars drivers know least.

Keep it off: that's the first response to an identical slip, anywhere in Great Lumley or the remainder of Durham you are.

## Already started the motor with AdBlue in the diesel tank around Great Lumley?

Then your tank is no longer where the AdBlue is.

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

You may see the engine running unevenly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Great Lumley Millennium Green or halfway across Great Lumley.

No restarting to test: pull over when safe, then turn everything off.

Each start pulls more of that through.

Great Lumley lies under a mile from the A1(M); if you were on it, leave by the first junction and pull up safely instead of carrying on.

Mileage matters: every mile pushes the AdBlue deeper in, and so driving towards Durham, under 5 miles away, makes a much bigger job than hopping across Great Lumley to the car park by Christ Church Lumley.

Tell us about how far it had come.

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

If it is caught early, long-term damage is very rare.

## What emptying AdBlue from a diesel involves in Great Lumley

Wherever it has stopped around Great Lumley — a forecourt, a layby, a driveway, a road by Lumley Evangelical Church — our van travels to the vehicle.

The work depends on three answers, which our engineers get first — what got in, the amount, and if the engine has run.

The contaminated diesel and the urea come out together when that tank is drained, right there.

The system is flushed thoroughly, which counts more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own.

The filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested.

Engine not run? Then expect roughly half an hour on site for most jobs.

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

Bleeding the system with new diesel comes last.

You drive off as soon as we have started it, and it makes no difference whether the vehicle is on a drive in Great Lumley or in a bay by Chester-Le-Street.

Our technicians confirm it runs correctly on clean diesel before we leave.

Our technicians do it all wherever the vehicle has stopped, and it never has to go to a garage.

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

## Great Lumley and Durham: AdBlue drains across the area

Our vans that answer AdBlue jobs in Great Lumley also cover the spots round it, Castle Dene, Lumley Thicks and Woodstone Village among them, and most of Durham beyond, across the DH postcode area.

Near a border, or anywhere awkward to explain? Checking is better than assuming, so phone.

Anywhere your car sits — a driveway at home, a residential street, a car park, a forecourt — we drain it on the spot, and there's no need to bring it to us; that suits Great Lumley, a village, well.

## What does AdBlue in a diesel tank cost to sort out in Great Lumley?

No flat figure could be honest, since every job is different.

What changes the price is, firstly, whether your engine has run and for how long; then how much AdBlue was put in; and after that where the car is and whether a technician can get to it safely, which is easier on an open drive than in a tight gap behind Great Lumley Community Centre.

Before a figure, not after, each call from Great Lumley begins with the same three checks: the liquid, the amount, plus if it ran.

Those replies turn a range into a straight price.

Before a van heads out, you hear the price on the phone. Then payment is on the day, card or over the phone, with nothing upfront.

As our engineer is on the way, dig out your policy: many cover misfuelling.

## Great Lumley: still next to the car?

Right now, the most helpful thing to do with your car is to leave it.

Motor off, keys out, ignition off.

Petrol in Diesel handles the remainder, in Great Lumley or anywhere within Durham, once you ring 0333 366 0103 saying it was AdBlue, roughly how big an amount, and whether it ran.
