# AdBlue in the Diesel Tank in Whitstable? Keep It Switched Off

AdBlue in your diesel tank? Then leave your motor off — and the ignition as well.

In plain terms, AdBlue is just urea in water.

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

In Whitstable, AdBlue in a diesel tank found before the engine runs usually comes down to a drain and a thorough flush, just where the vehicle is.

Ring 0333 366 0103 before you do anything else.

## AdBlue in the diesel tank around Whitstable: the first few minutes

Do these:

- Pull your keys out, and so no one switches your ignition on.

- If you're anywhere near moving traffic, put your hazards on.

- The empty bottle or the till receipt tells us the fluid and the amount, so don't throw it away.

- Give us a postcode starting CT5 1, or whichever street is nearest, and our van reaches you directly — so ring from wherever you are.

Things not to do:

- Not even briefly, and not to shift the vehicle: your engine stays off.

- Your ignition stays off: on lots of diesels, switching it on is enough to start your pump.

- Do not top up with diesel to dilute it. AdBlue does not dilute in diesel; it separates out.

- Do not drive it anywhere, not even a short distance up Gladstone Road.

- Don't try to drain it yourself by the roadside.

Moving the vehicle off the island is a job for attendants to help with, wherever Whitstable forecourt you are on, the JET or any other.

Parked on your own driveway? Then it stays exactly where it is.

## AdBlue in a diesel tank: what it does

Not the motor but your exhaust is where AdBlue belongs.

It goes into its own tank and is sprayed into the exhaust gas to clean it.

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

It does not combine. After it's tipped into the tank, AdBlue behaves nothing like fuel.

Heavier than diesel, it sinks and pools below it — the very place the intake draws from.

Simplest of all: one that got AdBlue in Tankerton last night and hasn't been started since. The liquid sits at the foot of your tank, undrawn — though it will be first through once your engine runs, before any diesel at all.

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

Pipes carrying AdBlue mean harm overnight for a car parked around Whitstable. Just in the tank, it stays the same.

Then there's the water: it offers no lubrication to the parts that rely on it the most — the injection pump and each injector.

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

Petrol put into a diesel on Tesco's forecourt leaves your fuel watery — that's the main fault.

Blended into your diesel and sitting unused, it's no threat for now; running your motor is the damage.

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

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

Deposits and corrosion stay after the next tankful, and AdBlue splits back from the diesel, and so thinning it can't work. Hence the flush counts more, and turning your key "to see" does more harm here than almost any other mistake — in South Tankerton or the centre of Whitstable equally.

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

Wherever around Kent your vehicle has stopped, an unstarted motor leaves the AdBlue yet in the reservoir: the easiest bit of any fuel system to empty.

## How AdBlue ends up in a diesel tank in Whitstable

It is not on purpose. Plenty of cars keep the AdBlue cap alongside the diesel one, now and then behind a single flap, and muddling them up is easy in poor light.

Mostly it occurs with a bottle bought on the way home and poured in on the drive, not at the forecourt.

Mostly, it happens in one of a couple of familiar ways.

A warning light comes on during the school run, and the top-up happens in a hurry outside Whitstable and Seasalter Endowed Church of England Junior School.

A bottle is poured in at the end of the day on a drive just off High Street.

One more pattern: darkness, the car park outside The Smack Inn, and someone opening that flap for the first time.

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

Wherever you are around Whitstable or the rest of Kent, it's the same mistake and the same first answer: leave it off.

## AdBlue in the diesel tank in Whitstable, and the motor started?

Then the AdBlue has left that tank.

Your filter and lines have had it sucked through, and any running carries it on to the high-pressure pump and each injector.

Perhaps returning from Cornwallis Circle Recreation Ground, or midway across Whitstable, the motor might run lumpy, smoke, lose pace, light up the dash or stall.

Once you safely can, pull over then turn everything off — without restarting to test.

Each start pulls more of it through.

On the M2, under 10 miles from Whitstable, the first junction is where to leave, and somewhere sensible is where to stop — not carrying on.

How far it went matters. A couple of hundred yards across Whitstable to the car park by The Playhouse is a very different job from a run towards Canterbury, under 10 miles away, with the AdBlue reaching further into the system with each mile.

Roughly how far had it come? Tell us.

Wherever your car came to a stop is where all of it gets done, even with more to clean out once the engine has been running.

If it's spotted soon, permanent damage is very uncommon.

## Clearing AdBlue in a diesel around Whitstable: what it takes

The car remains where it is, whether that's a street near United Reformed Church, a drive, a layby or a forecourt around Whitstable, and our van comes to it.

What got in, about the quantity, plus whether the engine has been run: our technicians check before all else, since those decide the work.

Right there, your tank is then emptied, and all of the polluted diesel and the urea come out as one.

A careful flush counts much more after AdBlue than after petrol, since what remains won't wash away by itself.

Fresh diesel goes in after your filter is cleaned — or swapped, when it needs to be — and then your vehicle is tested.

If the engine has not run, the majority of jobs take about half an hour once we are there.

Explosion-proof pumps mean a busy forecourt safe to work on, and they're quiet enough to spare the neighbours at night.

Priming the system with clean diesel comes at the end.

You set off as soon as our engineers have started the car, and it makes no difference whether your car is on a driveway around Whitstable or in a space outside the nearest station.

The check before our technicians leave is that it runs properly on new diesel.

No workshop is needed at any stage, with the whole job done on the spot.

Insurers ask for a VAT invoice and an engineer report, and both come afterwards.

## About Whitstable, briefly

Whitstable is a coastal town situated in Kent, England, where the coastline meets the estuaries of the Swale and the Thames. It is located near the city of Canterbury and the town of Herne Bay. The town is known for its seaside setting and is a part of the Canterbury district. Whitstable has become a notable place in the region, with its own distinct character.

## AdBlue drains across Whitstable and Kent

Over the CT postcode area, the teams answering AdBlue jobs in Whitstable serve much of Kent as well, Lower Island, Thurston Park and Church Street among them.

Close to a border, or somewhere tricky to pin down? Checking beats assuming, so ring.

Whitstable is a coastal town, and an on-site drain suits it: whether your car is on a home drive, a residential street, a car park or a forecourt, we drain it where it sits, so it never needs to be shifted to us.

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

There's no honest single quote, because the jobs are not the same.

The cost changes first with how long, if at all, your engine has been running, and next with the amount of AdBlue that went in. After that it rests on where the car is and whether a van can get to it safely, which is easier on an open driveway than in a tight space behind St. Alphege Church.

What was put in, what quantity, plus if it ran: every Whitstable enquiry begins with precisely that, before a quote, not after.

Given those replies, the range narrows to a single fixed number.

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

Look at your insurance while we're on the way: many include misfuelling cover.

## Still alongside the vehicle in Whitstable?

Then the most handy thing you can do is nothing to your car.

Keys out; engine and ignition off.

Petrol in Diesel takes over the remainder, across Whitstable or anywhere in Kent, after you phone 0333 366 0103 to say it's AdBlue, about how big an amount, and whether it ran.
