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

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

Water with urea mixed in it: that is AdBlue.

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

If the engine hasn't run yet, AdBlue in a diesel tank is usually drained and carefully purged where your car stands around Stow Heath.

No step comes before ringing 0333 366 0103.

## Your next steps straight away, Stow Heath: AdBlue in the diesel tank

Do these:

- Remove the keys, and that stops someone switching the electrics on.

- If you are anywhere close to moving traffic, put the hazards on.

- Hold on to the till receipt or the empty bottle, so you can tell us what went in and about how much.

- Give us a postcode starting WV1 2, or whatever street lies closest, and our van finds you straight — so call from wherever you stand.

Do not:

- Don't start your engine, even for a moment to move the vehicle.

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

- No more fuel on top. The AdBlue won't mix, so it's wasted.

- Even a short way up Lilac Road is too far to drive the vehicle.

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

The staff on duty at any Stow Heath forecourt — the Esso among them — will normally lend a hand pushing it clear if you ask.

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

## What does AdBlue do in a diesel tank?

The engine is not what AdBlue is made for; your exhaust is.

Stored in a dedicated tank, it is squirted into the exhaust to clean the gases.

A fuel pump is not made to cope with it, and AdBlue was never supposed to go through one.

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

Heavier than diesel, it sinks and pools underneath it — the same place the intake sucks from.

A car filled on a drive in Moseley Village yesterday evening and left unstarted is the simple case. No pump has pulled the AdBlue up so far — though once your engine turns, that's what goes first, directly from the bottom of your tank.

It causes two kinds of harm from there.

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, so it keeps running on the parts it hits for as long as it stays there.

Lines carrying AdBlue spell harm overnight for a vehicle sitting in Stow Heath. Only inside your tank, it stays the same.

The water in it does damage of its own: the high-pressure pump and the fuel injectors rely on diesel to lubricate them, and water offers them nothing.

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

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

Mixed through the diesel and sitting still, it is no threat at that stage; using the engine does the damage.

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

Since it doesn't burn, running it through is not an option.

Whether the vehicle is in Stowlawn or the heart of Stow Heath, firing it up "to see" does more harm in this case than nearly any other mistake, and the flush matters for more. The reasons: it won't stay blended, so watering it down is impossible; and deposits and corrosion outlast the following tankful.

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

Clearing a tank is the easiest part on any fuel system, and without running, the AdBlue stays in it — wherever around West Midlands the vehicle sits.

## AdBlue in a diesel tank in Stow Heath: how it ends up there

After dark, two caps side by side — the AdBlue one and the diesel one, occasionally behind one flap — can look the same. No one intends it; many layouts invite it.

A bottle bought while driving home and tipped in at home, instead of at the forecourt, is the usual story.

A couple of familiar ways account for most cases.

Rushing, outside East Park Academy, after a warning light came on during the school run, someone tops up the vehicle.

Near Culwick Street, someone tips a bottle in on the drive after work.

Else, after dark by The Gate Inn, your vehicle gets refilled by a driver using that flap for the first time.

The least familiar vehicles see it the most — hire cars, brand-new cars, fleet cars, and the spare vehicle in a home with both fuels.

Same mistake, an identical first response — leave it off — anywhere you are in Stow Heath or the remainder of West Midlands.

## AdBlue in the diesel tank around Stow Heath, and the motor started?

The AdBlue has left the tank, then.

Via the fuel filter, through the pipework, and — given any running time — on to the injection pump and every injector: that's how far it has gone.

Expect lumpy running, exhaust smoke, falling power, warnings on the dash, or a cut-out — coming back from Black Country Millennium Forest, perhaps, or midway across Stow Heath.

No restarting to check: stop when it is safe, then turn it off.

Each start pulls more of that through.

On the M6, under 5 miles from Stow Heath, the next junction is where to exit, and anywhere sensible is where to stop — not driving on.

Hopping across Stow Heath to the car park by East Park Library is one matter; heading for Wolverhampton, under 3 miles away, is something else, because each mile carries the AdBlue deeper in. So distance matters.

Tell us roughly how far it had come.

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

Caught early, it very rarely leaves long-term damage.

## Stow Heath: how AdBlue is emptied from a diesel

A road beside Ettingshall Village Community Activities Partnership Centre, a driveway, a lay-by or a filling station: anywhere the car has come to rest around Stow Heath, our engineers travel to it.

What went in, about how much, and if your motor has turned over: we check first, because those decide the work.

Then that tank is cleared where the car waits, so the polluted fuel and the AdBlue come out together.

With AdBlue, far more than with petrol, the flush counts: the whole system is flushed right through because what remains won't wash away unaided.

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

About half an hour on site is usual for most jobs where the motor has not run.

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

Fresh diesel goes in to prime the system, and that is the final step.

At that point our technicians start the car and you drive off, whether from a parking space outside Wolverhampton or a drive in Stow Heath.

The test before we leave is that it runs properly on clean diesel.

No garage is needed at any stage, with the entire job done then and there.

Your insurer is likely to want an engineer's report and your VAT invoice — both yours once this job is done.

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

Because the callouts differ, a single figure wouldn't be fair.

Whether your engine has run, and for how long, comes first in what moves the price. How much AdBlue got in comes next, and then the location of the car, since an open driveway is easier for our van to reach safely than a tight spot behind St Matthew.

Before any figure, not afterwards, each enquiry from Stow Heath begins with three questions: the liquid, the quantity, plus if the engine ran.

Those answers narrow a range down to one number.

Priced on the call before the engineer heads out, it is paid for that day — card or phone, nothing in advance.

Check your policy while we are on the way: plenty carry misfuelling cover.
