# Don't Start It: AdBlue in a Diesel Tank in Mill Shaw

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

Water with urea dissolved in it: that is AdBlue.

The harm begins once it's pulled through the lines — it will not burn, and it won't combine with diesel.

If the motor has not run yet, AdBlue in a diesel tank is usually emptied and thoroughly purged where the car sits around Mill Shaw.

Nothing comes before calling 0333 366 0103.

## Those opening minutes: AdBlue in the diesel tank in Mill Shaw

Things to do:

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

- Hazards on, if moving traffic is at all close.

- Which fluid, and about what volume? Save the bottle or your receipt, and we can see.

- Ring us from where you are. A postcode starting LS11 8, or the name of the nearest street, gets our van to you without a search.

Do not:

- No starting the motor — not briefly, not to reposition the car.

- Many diesels power their fuel pump the instant the ignition comes on, so keep the car off.

- AdBlue doesn't mix in diesel — it separates out — so adding more diesel will not thin it.

- Do not drive it anywhere, not even a short way along Millshaw.

- Beside the road, do not try emptying it on your own.

The staff working at any Mill Shaw forecourt — the Asda among them — will usually lend a hand pushing it clear if you ask.

If you are on your own drive, leave it just where it sits.

## What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not your motor.

Its own reservoir holds it, and from there it's sprayed into your exhaust, and there it treats the gas.

Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is designed to handle it.

Poured in with the diesel, it keeps separate rather than mixing — entirely unlike fuel.

It's heavier than diesel, so it sinks and gathers at the bottom of the tank, which is where the pickup sucks fuel from.

A vehicle topped up on a driveway in Beeston Royds overnight and not started since is the straightforward case. Nothing has pulled the AdBlue up so far — though when your engine turns, that is what is pulled first, directly from the bottom of your tank.

Two kinds of damage follow from there.

Crystals and corrosion. As the water evaporates, it strands urea that hardens in filters and tiny channels; and, since it eats at certain metals, each part it reaches suffers for as long as it remains inside.

Overnight, a car parked around Mill Shaw with AdBlue through its pipework gets worse; if it is only inside the tank, nothing changes.

Water protects nothing. The injection pump and each injector depend on diesel running through them, so the water content damages them by itself.

## Why AdBlue in a diesel is regularly more serious than petrol

Put petrol in a diesel at the Esso and you have a fault of thin fuel.

No damage is done as long as it sits unused, mixed into your diesel — only once your engine works on it.

With AdBlue in a diesel, the fluid itself is plainly the wrong one.

It can't just be run through, since it does not burn.

Deposits and corrosion remain after the next fill, and AdBlue splits again from the diesel, so watering it won't help. That is why the flush matters so much, and trying the engine "to see" does more harm with AdBlue than nearly any other mistake — in Beeston Hill or the heart of Mill Shaw equally.

The same good news applies as with petrol.

Not run? Then the AdBlue sits just in the tank, the easiest section of the entire system to clear, anywhere the vehicle has come to rest across West Yorkshire.

## How AdBlue ends up in a diesel tank around Mill Shaw

After dark, two caps together — the AdBlue cap and the diesel one, occasionally behind one flap — can look the same. Nobody intends it; many designs allow it.

It usually takes place at home, from a bottle bought on the journey home, rather than at the filling station.

The ways it happens are few and familiar.

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

After work, a bottle is tipped in on a drive near Global Avenue.

One more pattern: dim light, a pub car park by The Whistlestop, and a driver opening that flap the first time.

It crops up most in a hire car, a brand-new vehicle, a company car, or the spare motor in a home with both fuels — the vehicles people know the least.

Wherever in West Yorkshire, Mill Shaw as well, the mistake doesn't change, and nor does the first step: keep it off.

## Started your engine with AdBlue in your diesel tank around Mill Shaw?

Then the tank is no longer where the AdBlue is.

Via the filter, along the pipework, and — with any running — on to the injection pump and every injector: that's how far it travels.

You may notice your motor running roughly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Hunslet Nelson Cricket Club or halfway across Mill Shaw.

No starting it again to test: pull over when it is safe, then turn it off.

Every start pulls more of it through.

On the M621, under a mile from Mill Shaw, the first junction is where to exit, and somewhere sensible is where to stop — not carrying on.

Mileage counts: each mile pushes the AdBlue deeper in, so driving towards Leeds, under 3 miles away, makes a far bigger job than crossing Mill Shaw to the car park by The Church in Cottingley.

Tell us roughly how far it had come.

We do all of the cleaning where the vehicle has come to a stop, and once the engine has been run there is more of it.

Long-term damage is very rare when it's noticed early.

## What does an AdBlue drain on a diesel involve around Mill Shaw?

Anywhere it has come to rest around Mill Shaw — a forecourt, a lay-by, a drive, a street beside Marks & Spencer — the van comes to your vehicle.

Three answers decide the work, and so before anything else our technicians ask what was put in, roughly what quantity, plus if the motor has run.

The polluted diesel and the urea leave as one after that tank is drained, on the spot.

A careful flush counts far more after AdBlue than with petrol, because residue will not clear away on its own.

Next, your filter: cleaned, or replaced when it must be. Then fresh diesel, then a test of the vehicle.

The majority of these jobs are a half-hour job once our engineers arrive, if your motor has not run.

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

The last step is to prime the system on clean diesel.

Firing it up comes next, and then you set off from where the car is parked, by Cottingley or on a driveway around Mill Shaw.

The test before our engineers go is that it runs properly on clean diesel.

No workshop is needed at any stage, with the whole job done then and there.

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

Each job differs, so no single price is fair.
