# AdBlue in the Diesel Tank in Henwood Green? Keep It Switched Off

If AdBlue has gone into the diesel tank, leave your engine off and keep the ignition off.

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

Unlike fuel, it neither ignites nor mixes, and nothing starts till your engine pulls it round.

In Henwood Green, AdBlue in a diesel tank caught before the motor runs usually comes down to a drain and a thorough flush, right where the car is.

Nothing comes before ringing 0333 366 0103.

## AdBlue in the diesel tank in Henwood Green: the first few minutes

To do:

- Pocket your keys, and that prevents someone turning the electrics on.

- Hazards on, if moving traffic is anywhere close.

- The empty bottle or the receipt tells us the product and the quantity, so don't bin it out.

- Tell us a postcode starting TN2 4, or whatever street lies nearest, and the van finds you directly — so call from wherever you stand.

Don't do these:

- Do not start the engine, even for a moment to shift the car.

- Plenty of diesels run their pump the moment the ignition comes on, so leave the car off.

- No extra fuel added. The AdBlue won't blend, so it's pointless.

- Even a short stretch down Heskett Park is too far to drive the car.

- By the road, do not try draining it yourself.

Get the people behind the counter to help you roll your car off the pumps if you are on a forecourt around Henwood Green, whether it's the Esso or somewhere else.

On your own drive, do not move it at all.

## What does AdBlue do in a diesel tank?

Made for the exhaust, AdBlue has no business in your engine.

Stored in a dedicated tank, it's injected into the exhaust to clean the fumes.

Nothing in it is meant to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Fuel blends; AdBlue, once tipped in, will not. Its behaviour is not at all like diesel's.

Denser than diesel, it sinks and collects underneath it — the same place the pickup sucks from.

A car topped up on a driveway in Kippings Cross overnight and not started since is the straightforward case. No pump has sucked the AdBlue up yet — though once your motor runs, that is what goes first, directly from the bottom of that tank.

After it's pulled 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's corrosive to some of the metals a fuel system is made from, so it keeps running on the components it gets to for as long as it stays there.

Where the AdBlue has reached the lines, leaving it till morning around Henwood Green leaves things worse. Inside your tank only, time costs nothing.

Water protects nothing. The injection pump and every injector depend on diesel flowing through them, so the water content harms them in its own right.

## Why is AdBlue in a diesel regularly the bigger issue?

Petrol put into a diesel on BP's forecourt leaves your fuel watery — that's the whole issue.

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

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

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

Whether your car sits in Keys Green or the centre of Henwood Green, firing it up "to see" costs more with AdBlue than nearly any other error, and the flush matters for more. Why: it will not stay blended, and so diluting it is impossible; and crystals and corrosion outlast the following fill.

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

Never run? Then the AdBlue waits only inside your tank, the easiest section of the entire system to clear, wherever your car has come to rest in Kent.

## Henwood Green: how AdBlue ends up in a diesel tank

No one means to do it. The AdBlue filler on many vehicles sits right next to the diesel filler, sometimes under the same flap, and the two caps can look alike in poor light.

Usually it's not the filling station: someone buys a bottle driving home and tips it in at home.

The ways it takes place are few and familiar.

Midway through the drop-off, the dashboard warns, and outside Pembury School the refill is hurried.

Near Berkeley Close, someone tips a container in at home after work.

Else, in dim light by King William IV, your vehicle is refilled by someone using that flap the first time.

It takes place most in the motors drivers know least: a hire car, a new vehicle, a company car, or the second motor of a household with one diesel and one petrol.

Leave it switched off: that's the first step to an identical mistake, wherever around Henwood Green or the rest of Kent you happen to be.

## Already started the engine with AdBlue in your diesel tank around Henwood Green?

The AdBlue has left your tank, then.

The filter and lines have had it sucked through, and any running time takes it on to the high-pressure pump and every injector.

Expect rough running, smoke, lost power, warnings on your dash, or a cut-out — returning from Woodside Recreation Ground, perhaps, or midway across Henwood Green.

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

More of that is pulled through with each start.

Leave the M26, under 15 miles from Henwood Green, at the next junction and park somewhere safe, rather than carrying on.

A quick hop across Henwood Green to the car park by Pembury Baptist Church is one thing; heading towards Brighton and Hove, under 50 miles away, is something else, since every mile pushes the AdBlue further in. So distance counts.

About how far it had come is worth telling us.

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

Caught quickly, it very seldom leaves long-term damage.

## What clearing AdBlue from a diesel involves in Henwood Green

Wherever it has stopped around Henwood Green — a filling station, a layby, a driveway, a street beside Pembury Library — our van travels to the vehicle.

Which fluid got in, about the quantity, and if the motor has turned over: we check first, since those decide the work.

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

With AdBlue, far more than with petrol, flushing counts: the whole system is flushed right through because residue will not flush out by itself.

After that, the fuel filter: flushed, or replaced if it has to be. Then fresh diesel, then a check of the car.

Roughly half an hour on site is usual for most jobs where the motor hasn't run.

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

Lastly, your system is primed with fresh diesel.

You set off as soon as our engineers have started the engine, and it makes no difference whether the car is on a drive around Henwood Green or in a space at High Brooms.

Our technicians make sure it runs smoothly on new diesel before leaving.

We do it all wherever your car has stopped, and it never has to be taken to a workshop.

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

## What does AdBlue in a diesel tank cost to sort out around Henwood Green?

Every job is different, and so no fixed price is honest.

What shifts the price is, first of all, whether your engine has run and for how long; then how much AdBlue was put in; and finally where your car is and whether a technician can get to it safely, which is easier on an open drive than in a tight space behind War Memorial.

Ahead of a quote, never afterwards, each call from Henwood Green begins with three questions: the liquid, the quantity, and whether it ran.

As the van is on the way, check your insurance: many include misfuelling.
