# Don't Start It: AdBlue in a Diesel Tank in Hill Grove

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

Water with urea mixed in it: that is AdBlue.

The trouble starts once it's pulled through the lines — it will not burn, and it won't blend with diesel.

In Hill Grove, AdBlue in a diesel tank caught before your engine runs usually means a drain and a thorough flush, right where your car is.

Phone 0333 366 0103 before you do anything else.

## What to do right now, Hill Grove: AdBlue in your diesel tank

Things to do:

- Pull the keys out, and so nobody switches the ignition on.

- Put the hazards on if you're at all near moving traffic.

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

- Ring us from where you are. A postcode starting SO32 2, or the name of the closest street, gets the van to you without a search.

Things not to do:

- No starting your engine — not briefly, not to shift your vehicle.

- Plenty of diesels power their fuel pump the instant your ignition goes on, so leave the vehicle off.

- No more fuel added. The AdBlue will not blend, so it's wasted.

- Keep the car where it is rather than driving it anywhere, even a short way up Dodds Lane.

- No draining it yourself, at all, at the verge.

Ask the attendants to help you move your vehicle off the pumps if you're on a forecourt in Hill Grove, whether it is the Sainsbury's or somewhere else.

At your own drive, don't move it at all.

## What does AdBlue do in a diesel tank?

Not your engine but your exhaust is where AdBlue belongs.

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

A fuel pump isn't made to take it, and AdBlue was never supposed to travel through one.

Poured in with the diesel, it keeps separate rather than mixing — quite different from fuel.

It is heavier than diesel, so it sinks and collects at the bottom of your tank, which is where the pickup pulls fuel from.

The first thing the fuel system pulls through, after it runs, is the AdBlue. So a vehicle that had AdBlue poured in on a drive in Mislingford last night, and has not been started since, is still the simple case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.

Once it is drawn in, the harm comes in two forms.

What is left once the water goes is urea, which forms crystals: they lodge in tiny channels and clog filters. Worse, it eats at certain metals in a fuel system, and keeps going till it is flushed out.

A motor left sitting in Hill Grove with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank isn't.

Water lubricates nothing. The injection pump and each injector need diesel running past them, so the water part damages them by itself.

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

Fill a diesel with petrol by mistake over at the Premier, and this problem is diluted fuel.

No damage comes while it sits put, mixed into the diesel — only when your engine works on it.

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

Not burning, it cannot just be run through.

Deposits and corrosion remain through the following fill, and AdBlue separates back from the diesel, and so watering it can't help. That is why the flush counts so much, and trying your engine "to see" costs more with AdBlue than nearly any other mistake — in Waltham Chase or the heart of Hill Grove alike.

The good news is the same as with petrol.

Never run? Then the AdBlue waits only in the tank, the easiest section of the entire system to empty, wherever the vehicle has stopped across Hampshire.

## How AdBlue ends up in a diesel tank around Hill Grove

Nobody means to do it. The AdBlue filler on many motors waits right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light.

It mostly occurs at home, from a bottle grabbed en route home, rather than at the forecourt.

The ways it occurs are few and familiar.

Rushing, outside Swanmore Church of England Aided Primary School, after a warning lamp came on during the school run, a parent tops up your car.

Someone pours the bottle in outside their house, right off Cott Street, as the day ends.

Otherwise, in dim light outside The Hunters Inn, the vehicle is refilled by someone using that flap the first time.

It crops up most in a hire car, a new car, a fleet car, or the spare motor in a home with both fuels — the cars people use the least.

Keep it off: that is the first response to the same mistake, anywhere around Hill Grove or the remainder of Hampshire you happen to be.

## Hill Grove: started the motor with AdBlue in your diesel tank?

If so, the AdBlue is no longer in that tank.

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

Maybe returning from Swanmore Recreation Ground, or part way across Hill Grove, your engine might run lumpy, smoke, drop pace, flash the dash or stall.

Stop when safe. Turn off. Leave the car off instead of testing it again.

Each start pulls more of it through.

If you were on the M27, under 10 miles from Hill Grove, come off at the next junction and stop somewhere safe instead of pressing on.

Each mile pushes the AdBlue deeper in. That's why a hop across Hill Grove to park near Swanmore Methodist Church and a drive of under 15 miles towards Winchester are very separate jobs.

Let us know roughly how far it had come.

Once the engine has run, the flush covers more, and all of it is done where the car has stopped.

Very rarely does it leave long-term damage if it's spotted quickly.

## What does an AdBlue drain on a diesel involve around Hill Grove?

The vehicle stays put, whether that's a street near Swanmore War Memorial, a drive, a lay-by or a forecourt in Hill Grove, and the van comes to it.

Which fluid was put in, roughly the quantity, plus whether your engine has turned over: our engineers ask before all else, since those decide the job.

The polluted diesel and the urea leave as one after that tank is emptied, right there.

With AdBlue, far more than with petrol, the flush matters: the fuel system is flushed right through because what remains will not flush away by itself.

Clean diesel goes in after your filter is cleaned — or swapped, if it needs to be — and then the car is tested.

If your motor has not run, most jobs take about half an hour once we are there.

The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house after dark.

The last step is to bleed the fuel system on new diesel.

You drive off as soon as our technicians have started it, and it makes no difference whether your car is on a driveway around Hill Grove or in a space outside Botley.

Before leaving, we confirm it's running smoothly with fresh diesel in.

We do it all wherever the vehicle has ended up, and it never has to be taken to a workshop.

The insurer is likely to want an engineer's report and your VAT invoice — both yours afterwards.

## AdBlue drains around Hill Grove and across Hampshire

Over the SO postcode area, the teams taking AdBlue call-outs in Hill Grove reach much of Hampshire too, Hillpound, Swanmore and Upper Swanmore included.

Close to a boundary, or anywhere tricky to pin down? Asking beats guessing, and so phone.

Wherever your vehicle stands — your drive at home, a residential street, a car park, a filling station — we drain it on the spot, and there's no need to bring it to us; that suits Hill Grove, a rural hamlet, well.

## AdBlue in a diesel tank around Hill Grove: the cost of fixing it

Every job is different, so no fixed quote would be fair.

Three things move the cost: whether the motor has run and for how long, how much AdBlue went in, and where the vehicle is. That last one rests on whether a technician can get to it safely, and an open driveway is simpler than a tight spot behind Swanmore Lawn Tennis Club.

With that in mind, each call from Hill Grove opens by asking the same trio — which fluid got in, how much, if the engine ran — before a quote.

Their answers narrow the range down to a single figure.

Before anyone heads out, you hear the price by phone. And payment is on the day, by card or by phone, with nothing upfront.

Look at your insurance while we are on the way: many carry misfuelling cover.

## In Hill Grove and still next to the car?

Right now, the most helpful thing to do with your vehicle is to not touch it.

Keys out, motor off, ignition off.

Ring 0333 366 0103: AdBlue, the amount, and if it ran is all our technicians ask. Petrol in Diesel takes over the rest throughout Hampshire, Hill Grove too.
