# AdBlue in a Diesel Tank in Penton Corner? Don't Start It

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

Water with urea dissolved in it: that is AdBlue.

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

If the engine hasn't run yet, AdBlue in a diesel tank is normally emptied and carefully rinsed where the vehicle sits in Penton Corner.

Before anything, call us on 0333 366 0103.

## AdBlue in your diesel tank in Penton Corner: the first few minutes

Do:

- Remove your keys, which stops anyone switching the electrics on.

- If you're at all close to moving traffic, put your hazards on.

- The empty bottle or your receipt tells us the product and the quantity, so do not bin it away.

- Call just where you are. Say a SP11 8 postcode or the nearest street name, and no one has to hunt for you.

Never do these:

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

- Many diesels run their pump the instant your ignition comes on, and so keep the car off.

- No more fuel on top. The AdBlue will not blend, so it is wasted.

- Any driving at all is best avoided, even a short way up Short Lane.

- Emptying the tank yourself beside the road isn't one to try.

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

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

## What does AdBlue do in a diesel tank?

The engine isn't what AdBlue is made for; the exhaust is.

Stored in a separate tank, it's squirted into the exhaust stream to clean the fumes.

No part in a fuel pump is designed for this fluid — and no part of it was meant to go through one.

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

It sinks, since it's heavier than diesel, and pools down where the pickup takes its fuel from.

Once your pump runs, the AdBlue is first to go through. Until then it waits beneath the diesel, which is why a car topped up in Foxcotte yesterday and never started remains the straightforward one, provided nobody turns your key.

It does two kinds of damage from there.

It attacks certain metals found in fuel systems, working on any part it reaches till it's removed from the system. And once the water evaporates, the urea forms crystals that clog filters and lodge in narrow passages.

Overnight, a vehicle parked around Penton Corner with AdBlue through its pipework grows worse; where it is only in the tank, nothing changes.

Diesel protects the high-pressure pump and every injector as it passes; water offers none of that, and that is a separate form of harm.

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

Fill a diesel with petrol in error at the BP, and this issue is diluted fuel.

Blended through your diesel and left unused, it's harmless at that stage; running the motor is the damage.

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

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

It doesn't stay mixed, so it can't be thinned. And crystals and corrosion don't wash out with the next tank of fuel. That is why the flush matters more with AdBlue than with petrol, and why starting your motor "to see" costs more here than nearly anywhere else, whether the car is in Charlton or the middle of Penton Corner.

The same good news holds as with petrol.

Emptying a tank is the easiest job on any fuel system, and without running, the AdBlue remains in there — anywhere in Hampshire the vehicle sits.

## How AdBlue ends up in a diesel tank in Penton Corner

It is not deliberate. Plenty of vehicles keep the AdBlue cap alongside the diesel one, now and then behind one flap, and mixing them up is easy in poor light.

It mostly happens at home, from a container bought en route home, not at the forecourt.

A few familiar ways cover most cases.

Hurrying, outside Portway Junior School, after a warning lamp came on during the school run, a parent tops up the vehicle.

After work, a bottle is tipped in on a driveway near Beech Close.

Or your car is topped up in the car park outside The Bell Inn, in poor light, by a person who has never opened that flap before.

It crops up the most in a rental, a brand-new motor, a fleet motor, or the other car of a home with both fuel types — the cars drivers use least.

Leave it switched off: that is the first response to an identical slip, wherever in Penton Corner or the rest of Hampshire you are.

## Started your engine with AdBlue in your diesel tank around Penton Corner?

Then that tank is no longer where the AdBlue is.

Through the filter, along the pipework, and — given any running time — into the high-pressure pump and every injector: that's where it has gone.

Expect rough running, smoke, lost power, warnings on your dash, or a cut-out — returning from Gorse Plantation, perhaps, or midway across Penton Corner.

No starting it again to check: pull over once it is safe, then switch it off.

Every start pulls more of that through.

Leave the M3, under 15 miles from Penton Corner, at the next junction and park safely, not carrying on.

Hopping across Penton Corner to the car park by Penton Village Hall is one thing; driving for Winchester, under 15 miles away, is something else, because every mile carries the AdBlue further in. So mileage counts.

About how far it had come is worth telling us.

There is more to rinse out once your engine has been started, and our technicians do all of it where the vehicle has ended up.

When it is caught soon, lasting damage is very unusual.

## Emptying AdBlue in a diesel in Penton Corner: what it takes

We come to the car, wherever it has stopped around Penton Corner: a side street close to Holy Trinity, a drive, a lay-by or a forecourt.

The job depends on three answers, which we get before all else — what went in, the quantity, and whether the engine has turned over.

Next, draining the tank on the spot removes the contaminated diesel along with the AdBlue together.

A careful flush matters far more after AdBlue than after petrol, because what remains won't wash out on its own.

Next, your filter: flushed, or changed when it must be. Then fresh diesel, and then a check of the vehicle.

If the engine hasn't run, most jobs take about half an hour once our technicians arrive.

Quiet enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.

Bleeding your system with fresh diesel comes last.

Whether it's a parking space outside Andover or a driveway around Penton Corner, that is where our technicians fire it up and you set off.

We make sure it runs properly on new diesel before we leave.

Because the job is done in its entirety where the car is, a garage never comes into it.

Your insurer will want an engineer's report and your VAT invoice — each handed over afterwards.

Penton Corner lies within a network of similar small settlements, including Penton Mewsey and Penton Grafton, and is characterized by its semi-detached housing stock.

## AdBlue drains around Penton Corner and across Hampshire

The teams that answer AdBlue call-outs in Penton Corner also cover the locations about it, Penton Mewsey, Penton Grafton and Weyhill among them, and most of Hampshire beyond, across the SP postcode area.

Close to a border, or somewhere tricky to explain? Checking beats guessing, so ring.

A van that comes to you fits Penton Corner, a rural hamlet: there's no need to take the car to us, since our technicians drain it there, on a driveway, a residential street, a parking area or a forecourt.

## Penton Corner: what AdBlue in a diesel tank costs to fix

Because the callouts vary, a single price wouldn't be fair.

Whether the motor has been running, and for how long, comes first in what changes the cost. How much AdBlue was put in comes next, and then the location of your car, since an open driveway is simpler for a technician to reach safely than a tight spot behind The DEPOT.

That's why each call from Penton Corner starts with the same three queries, asked before giving a figure, not after: what got in, how much, and whether it's run.

With them, a range narrows to a single fixed number.

The quote is quoted during the call, before a van sets off; payment comes on the day, by card or over the phone, and nothing upfront.

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