# AdBlue in a Diesel Tank in East Liss? Don't Start It

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

In plain terms, AdBlue is just urea in water.

Being water-based, it will not ignite and won't blend with diesel; trouble only comes once the pump starts drawing it.

Caught before the motor has been run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the vehicle is in East Liss.

Before anything, ring us on 0333 366 0103.

## East Liss, AdBlue in your diesel tank: what to do right away

Things to do:

- Pocket the keys, and that stops anyone turning the power on.

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

- Which product, and roughly how much quantity? Save the bottle or the till receipt, and our technicians can know.

- Ring just where you are. Quote a GU33 7 postcode or the closest street name, and nobody has to hunt for you.

Do not:

- Not even for a second, and not to roll the car: your motor remains off.

- Do not switch the ignition on. On many diesels that alone runs the fuel pump.

- Pouring in more diesel does not work: AdBlue settles out rather than blending.

- Any driving at all is best avoided, including a short stretch up Hatch Lane.

- Don't try to drain the vehicle yourself at the roadside.

Moving your car off the island is a job for staff to help with, whichever East Liss forecourt you are on, the Esso or any other.

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

## What does AdBlue do in a diesel tank?

Meant for the exhaust, AdBlue has no business in your motor.

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

A fuel pump is not designed to take it, and AdBlue was never intended to go through one.

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

It drops, because it is heavier than diesel, and settles down where the intake takes its supply from.

Easiest of all: a vehicle that got AdBlue in The Mint last night and has not turned since. The liquid sits at the base of that tank, undrawn — though it will be the first thing through once the motor runs, ahead of any diesel at all.

From there it causes two kinds of damage.

What remains once the water goes is urea, which forms crystals: they lodge in narrow passages and clog filters. On top of that, it eats at certain metals in a fuel system, and carries on till it is cleared out.

Where the AdBlue is in the lines, waiting overnight in East Liss makes it worse. In the tank only, time costs nothing.

And there is the water: it offers no protection to the parts that rely on it the most — the injection pump and every injector.

## Petrol or AdBlue in a diesel: why AdBlue is regularly worse

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

No damage comes while it stays put, blended into the diesel — only once your motor runs on it.

AdBlue in a diesel is a different problem: not thin fuel, yet no fuel at all.

Because it does not burn, running it through isn't an option.

Deposits and corrosion remain after the next fill, and AdBlue separates again out of your diesel, so thinning it won't work. Hence the flush matters more, and trying the engine "to see" costs more with AdBlue than almost any other slip — in Rake Common or the centre of East Liss alike.

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

Not started? Then the AdBlue sits just in that tank, the simplest section of the entire system to empty, anywhere the vehicle has come to rest in Hampshire.

## AdBlue in a diesel tank in East Liss: how it ends up there

After dark, two caps side by side — the AdBlue cap and the diesel one, occasionally under one flap — may appear the same. No one intends it; plenty of designs allow it.

A bottle picked up while driving home and poured in outside the house, rather than at the forecourt, is the typical route.

It tends to happen in a couple of familiar ways.

The refill is hurried outside Liss Junior School, because the dash lit up with a warning as the kids were dropped off.

Close to Highfield Gardens, a driver tips a bottle in on that drive in the evening.

Else, after dark outside Liss Royal British Legion, your car gets refilled by a driver using that flap the first time.

It crops up most in a rental, a new motor, a company motor, or the other car of a home with one of each fuel types — the cars drivers know the least.

Keep it off: that's the first response to the same slip, anywhere around East Liss or the rest of Hampshire you happen to be.

## AdBlue in your diesel tank in East Liss, and the engine started?

In that case, the AdBlue is no longer inside your tank.

It has been drawn through your filter and the fuel lines, and if your engine ran for any time, it has reached the high-pressure fuel pump and the injectors.

Expect lumpy running, exhaust smoke, lost power, lights on your dash, or a cut-out — coming back from Newman Collard Playing Field, perhaps, or midway across East Liss.

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

More of it is pulled through with each start.

If you were on the Waterlooville Bypass, under 10 miles from East Liss, come off at the next junction and stop somewhere sensible rather than pressing on.

Each mile pushes the AdBlue deeper into the system. That is why crossing East Liss to park near Hope Church and a drive of under 25 miles towards Chichester are such different jobs.

Let us know roughly how far it had come.

There is more to clean out once the motor has been run, and our engineers do all of it where the vehicle has stopped.

Very seldom does it leave permanent damage when it's spotted quickly.

## What does an AdBlue drain on a diesel involve in East Liss?

A road by Liss Triangle Community Centre, a driveway, a lay-by or a filling station: wherever the vehicle has stopped in East Liss, our technicians travel to it.

What was put in, about the quantity, and if the motor has been run: our engineers check before all else, since those shape the work.

The polluted diesel and the urea come out together after your tank is emptied, on the spot.

With AdBlue, more so than with petrol, flushing counts: the fuel system is cleaned right through since residue won't flush out unaided.

Fresh diesel goes in after the filter is cleaned — or replaced, if it needs to be — and after that your car is tested.

The majority of these jobs are a half-hour job once our technicians arrive, provided your engine hasn't run.

The pumping gear is explosion-proof, so a busy forecourt is no fault, and it's hushed enough for a residential street after dark.

Bleeding your system with fresh diesel comes last.

You head off as soon as our engineers have started the engine, and it makes no difference whether your car is on a drive around East Liss or in a bay outside Liss.

It's checked on fresh diesel to confirm it runs correctly before our engineers head off.

The whole job is done where the vehicle is, so it never has to go to a garage.

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

## AdBlue drains across East Liss and Hampshire

The vans that answer AdBlue calls around East Liss also cover the places about it, Lower Green, East Hill and Liss among them, and most of Hampshire beyond, across the GU postcode area.

If you are near a border, or somewhere hard to describe, ring and ask instead of assuming.

East Liss is a residential suburb, and a call-out drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, our engineers drain it where it sits, so it never needs to be moved to us.

## AdBlue in a diesel tank around East Liss: the cost of fixing it

Each job differs, so no single quote is honest.

Whether your engine has run, and for how long, comes first in what shifts the price. How much AdBlue was put in comes next, and then the position of the car, because an open drive is simpler for our van to reach safely than a tight space behind Liss War Memorial.

For that in mind, every call from East Liss opens by asking the same trio — what went in, how much, if it ran — before a quote.

Those answers turn a range into a straight quote.

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

Misfuelling cover comes with many insurance policies, so it pays to look at yours before the van gets there.

## East Liss: still next to the vehicle?

Right now, the best thing to do with the car is to not touch it.

Ignition off, motor off, keys out.

Petrol in Diesel handles the rest, across East Liss or anywhere within Hampshire, after you phone 0333 366 0103 saying it's AdBlue, roughly what quantity, and if it ran.
