# AdBlue in the Diesel Tank in Kings Heath? Keep It Switched Off

Motor off, ignition off: that is how you start if AdBlue has got into your diesel tank.

AdBlue is urea dissolved in water.

Unlike fuel, it neither burns nor mixes, and nothing starts until the engine sucks it round.

In Kings Heath, AdBlue in a diesel tank caught before the motor runs normally comes down to a drain and a thorough flush, just where the vehicle is.

Before you do anything else, ring 0333 366 0103.

## AdBlue in the diesel tank around Kings Heath: the first few minutes

Do:

- Keys out — then nobody can power anything on.

- If you're at all near moving traffic, put the hazard lights on.

- Which fluid, and about what volume? Hang on to the bottle or the till receipt, and our technicians will see.

- Give us a postcode starting B14 7, or whichever street lies nearest, and our van finds you straight — so call wherever you stand.

Don't:

- Moving your vehicle just a few yards is no reason to fire up the engine.

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

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

- Leave the vehicle where it is rather than driving it anywhere, even a short way along All Saints Road.

- Emptying the tank yourself beside the road isn't one to try.

At a forecourt in Kings Heath, whether it's the Shell or another one, ask the staff to help you push your car clear of the pump.

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

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

AdBlue is made for your exhaust, not your motor.

From a dedicated tank it is fed straight to the exhaust, cleaning what the motor lets out.

Not one side fits the other: urea doesn't belong in an injection pump, and a pump cannot take urea.

Poured in with your diesel, it keeps apart rather than mixing — entirely different from fuel.

Denser than diesel, it sinks and pools underneath it — the same place the intake draws from.

Simplest of all: one that got AdBlue in Stirchley overnight and has not turned since. The AdBlue waits at the base of the tank, undrawn — but it will be first through if the engine starts, ahead of any diesel at all.

It does two kinds of damage from there.

What remains once the water goes is urea, which turns into crystals: they lodge in narrow channels and clog filters. On top of that, it eats at some metals in the fuel system, and carries on till it is flushed out.

Where the AdBlue has reached the lines, waiting till morning in Kings Heath leaves things worse. Inside your tank alone, waiting does nothing.

Water protects nothing. The injection pump and each injector need diesel flowing through them, so the water part harms them by itself.

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

Put petrol in a diesel at the Gulf and you have an issue of thin fuel.

It mixes with your diesel, and whilst it's inside your tank it does no harm; the harm comes from running the engine on it.

AdBlue in a diesel is another problem: not thin fuel, but no fuel at all.

Since it does not burn, running it through is not an option.

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 matters more with AdBlue than with petrol, and why starting the engine "to see" costs more here than nearly anywhere else, whether the car is in Billesley Common or the middle of Kings Heath.

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

Anywhere across West Midlands the car has come to rest, an unstarted engine means the AdBlue yet inside the tank: the easiest bit of any fuel system to clear.

## How AdBlue ends up in a diesel tank around Kings Heath

Plenty of vehicles put the AdBlue cap beside the diesel one, occasionally under a single flap, and after dark the two may look the same. No one means it.

A bottle picked up while heading home and poured in at home, instead of at the filling station, is the typical story.

It tends to occur in a couple of familiar ways.

The refill gets hurried outside St Dunstan's Catholic Primary School, because your dash lit up with a warning while the children were dropped in.

A driver tips the bottle in at home, just off Alcester Road, as the day ends.

Or a driver new to that flap refills your car in dim light, parked in the car park by The Pub at Kings Heath.

The least known vehicles get it most — rentals, new cars, fleet ones, and the spare motor of a home with both fuels.

Wherever you are in Kings Heath or the remainder of West Midlands, it's the same error and the same first answer: leave it off.

## Kings Heath: started the motor with AdBlue in the diesel tank?

The AdBlue has left that tank, then.

It has been pulled through the filter and the fuel lines, and if the engine ran for any time, it has got to the high-pressure fuel pump and the fuel injectors.

Maybe returning from Kings Heath park, or midway across Kings Heath, the motor might run rough, smoke, lose pace, flash the dash or stall.

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

With each start, more of that is pulled through.

Leave the Aston Expressway, under 5 miles from Kings Heath, at the first junction and stop safely, not carrying on.

Mileage matters: every mile pushes the AdBlue deeper in, so driving for Birmingham, under 5 miles away, gives a much bigger job than hopping across Kings Heath to the car park by Kings Heath Farmers' Market.

Roughly how far had it come? Tell us.

There's more to rinse out once your engine has run, and our engineers do all of it where your car has come to a stop.

Very seldom does it leave lasting damage if it's spotted quickly.

## What clearing AdBlue from a diesel involves around Kings Heath

Wherever it has stopped in Kings Heath — a filling station, a lay-by, a driveway, a street beside All Saints Parish Church — the van travels to the vehicle.

The work rests on three answers, which our engineers get before all else — what was put in, the quantity, and whether your motor has turned over.

On the spot, the tank is then drained, and all of the polluted diesel and the urea leave at once.

Residue from AdBlue won't wash out by itself, and so the fuel system gets a full flush, which counts far more here than for petrol.

Fresh diesel goes in after your filter is flushed — or swapped, if it needs to be — and after that the vehicle is tested.

The majority of these jobs are a half-hour job once we turn up, if the engine hasn't run.

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

Priming your system with new diesel comes last.

Whether it is a parking bay at the nearest station or a drive in Kings Heath, that is where we fire it up and you set off.

The test before our technicians head off is that it runs correctly on new diesel.

The whole job is done where the vehicle is, so it never has to be taken to a garage.

Afterwards, you are given paperwork for your insurer: a VAT invoice plus a written report from the engineer.

## AdBlue drains in Kings Heath and across West Midlands

Our teams that answer AdBlue calls around Kings Heath also cover the spots round it, Alcester Lanes End, Moor Green and Moseley among them, and most of West Midlands beyond, across the B postcode area.

If you are near a border, or somewhere hard to explain, ring and ask rather than guessing.

Kings Heath is a residential suburb, and a mobile drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it stands, so it never needs to be moved to us.

## Kings Heath: what AdBlue in a diesel tank costs to fix

Each job is different, and so no single quote is honest.

Whether the engine 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 the vehicle, because an open drive is easier for a technician to get to safely than a tight gap behind CircusMASH.

That's why every call from Kings Heath starts with the same three questions, asked before giving a figure, not after: what went in, how much, and if it's run.

When those are answered, a range turns into a single fixed number.

Before anyone heads out, you are told our price on the phone. And payment is on the day, card or by phone, with nothing in advance.

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

## Kings Heath: still beside the vehicle?

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

Ignition off, motor off, keys out.

Call 0333 366 0103 then tell us it is AdBlue, about how much, and whether it's run. Petrol in Diesel takes it from there, in Kings Heath or anywhere in West Midlands.
