# Don't Start It: AdBlue in a Diesel Tank in Merry Hill

With AdBlue in the diesel tank, your ignition remains off and so does your engine.

Water with urea dissolved in it: that's AdBlue.

Being water-based, it will not burn and never combines with diesel; trouble only comes when your pump starts drawing it.

In Merry Hill, AdBlue in a diesel tank caught before the motor runs usually means a drain and a thorough flush, just where the vehicle is.

No step comes before ringing 0333 366 0103.

## AdBlue in the diesel tank in Merry Hill: the first few minutes

Things to do:

- So no one can turn the ignition on, take your keys away.

- Near moving traffic? Then put the hazards on.

- Keep the till receipt or the empty bottle, and so you can tell us what was put in and about how much.

- Ring us from where you are. A postcode starting B66 2, or the name of the nearest street, brings our van to you without a search.

Don't:

- Do not start your motor, even for a moment to shift your car.

- The ignition remains off: on lots of diesels, switching it on is enough to start your fuel pump.

- No more fuel on top. The AdBlue will not blend, and so it is wasted.

- Even a short stretch along Kitchener Street is too far to drive the car.

- Emptying the tank yourself beside the road is not one to try.

Ask the people behind the counter to help you roll your vehicle away from the island if you're on a forecourt in Merry Hill, whether it is the JET or elsewhere.

On your own drive, don't move it at all.

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

Not your motor but the exhaust is where AdBlue belongs.

Kept in a separate tank, it is injected into the exhaust stream to clean the fumes.

No part inside an injection pump is designed for this fluid — and no part of that was intended to travel that way.

Inside a diesel tank it behaves really differently from fuel. It does not mix in.

The intake takes fuel from the deepest part of your tank, and that is precisely where AdBlue ends up: as it is heavier than diesel, it sinks.

When the pump runs, the AdBlue is first to go through. Until then it sits underneath the diesel, which is why a vehicle filled in Gib Heath yesterday and not switched on stays the straightforward case, provided nobody touches your key.

After it's drawn in, the harm takes two forms.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps working on the components it gets to for as long as it stays there.

If the AdBlue is in the pipework, waiting till morning around Merry Hill makes it worse. Inside that tank alone, waiting does nothing.

Water lubricates nothing. The high-pressure pump and every injector need diesel running through them, and so the water part harms them in its own right.

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

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

Mixed through your diesel and left unused, it's no threat for now; running the motor does the damage.

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

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

Whether your vehicle sits in Summerfield Park or the heart of Merry Hill, turning it over "to see" does more harm with AdBlue than nearly any other error, and the flush counts for more. The reasons: it will not remain mixed, so diluting it is impossible; and deposits and corrosion survive the following tankful.

The good news is the same as with petrol.

Emptying a tank is the simplest part on any fuel system, and with no start-up, the AdBlue remains in there — anywhere in West Midlands the car has stopped.

## How AdBlue ends up in a diesel tank around Merry Hill

In dim light, two caps together — the AdBlue cap and the diesel cap, occasionally under one flap — can appear the same. No one means it; many designs allow it.

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

The ways it happens are few and familiar.

The top-up gets hurried outside Oasis Academy Foundry, after your dash flashed with a warning while the children were dropped in.

After work, a bottle is tipped in on a drive close to Foundry Lane.

Otherwise, in dim light outside Soho Foundry Tavern, the vehicle gets refilled by a driver opening that flap the first time.

The least known vehicles see it the most — rentals, new ones, fleet cars, and the other car of a family with one of each fuel types.

Wherever across West Midlands, Merry Hill as well, the mistake does not change, and neither does the first step: keep it off.

## Already started your engine with AdBlue in the diesel tank around Merry Hill?

The AdBlue has left that tank, then.

Given any running time, it goes on to the high-pressure pump and every injector, having passed via your filter and lines.

Maybe coming back from Black Country Millennium Forest, or part way across Merry Hill, your engine may go lumpy, smoke, drop power, light up your dash or cut out.

Once safe, pull over then switch it off — with no turning it on again to see.

More of it is pulled through with each start.

Merry Hill lies under 3 miles from the M5; if you were on it, leave by the next junction and stop somewhere safe rather than driving on.

Every mile carries the AdBlue further in. That is why a hop across Merry Hill to park near Blue Plaque: Soho Foundry and a drive of under 3 miles for Birmingham are very different jobs.

Let us know roughly how far it had come.

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

When it is spotted early, long-term damage is very unusual.

## What emptying AdBlue from a diesel involves in Merry Hill

Wherever it has come to rest in Merry Hill — a forecourt, a layby, a drive, a road by Bishop Latimer Reformed Church — the van comes to the vehicle.

Before anything else we ask what got in, about how much, and whether the motor has run, since those answers settle the work.

Then that tank is emptied where the car sits, and so the contaminated fuel and the AdBlue come out together.

A careful flush counts far more after AdBlue than after petrol, since what remains won't clear away on its own.

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

Most of these jobs are a half-hour visit once our technicians turn up, if your engine has not run.

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

The last step is to bleed the system on fresh diesel.

You drive off as soon as we have fired it up, and it makes no difference whether the vehicle is on a drive around Merry Hill or in a bay outside The Hawthorns.

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

The whole job is done where your car is, so it never needs to be taken to a garage.

Insurers ask for a VAT invoice and an engineer report, and both come at the end.

## About Merry Hill, for a moment

Merry Hill is a suburban area in the West Midlands, situated on the riverside near Birmingham. Merry Hill has a mix of terraced housing and local amenities, with the area being approximately 2.1 miles from Birmingham city centre. Merry Hill sits at an elevation of 133 metres, with nearby places including Black Patch, Soho, and Winson Green. Merry Hill is part of the larger West Midlands conurbation, with London being around 103 miles to the southeast.

## AdBlue drains across Merry Hill and West Midlands

Black Patch, Soho and Winson Green are among the places around Merry Hill that the same teams serve, along with much of West Midlands beyond, throughout the B postcode area.

Close to a boundary, or anywhere awkward to explain? Asking beats assuming, and so phone.

Wherever your car stands — your drive at home, a side street, a car park, a forecourt — our engineers drain it on the spot, and there's no need to take it to us; which suits Merry Hill, a residential suburb, well.

## AdBlue in a diesel tank around Merry Hill: the cost of fixing it

Because each callouts vary, a flat figure would not be fair.

The price shifts first with how long, if at all, the engine has been running, and next with the amount of AdBlue that went in. After that it depends on where the car is and whether our van can reach it safely, which is simpler on an open driveway than in a tight gap behind James Watt's Mad Machine (Winson Green Metro Entrance).

For that in mind, every call from Merry Hill begins with the identical trio — which fluid went in, how much, if it ran — before any figure.

Given them, a range shrinks to one firm figure.

Quoted by phone before the van sets out, it is settled on the day — card or phone, no deposit.

While our engineer is travelling, dig out your insurance: plenty cover misfuelling.

## In Merry Hill and still alongside the car?

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

Keys out; motor and ignition off.

Say it's AdBlue, about how big an amount, and whether the engine ran, on 0333 366 0103. From there Petrol in Diesel takes over, in Merry Hill or wherever within West Midlands.
