# Don't Start It: AdBlue in a Diesel Tank in Green Hammerton

If AdBlue has got into the diesel tank, keep your motor off then leave your ignition off.

Chemically, AdBlue is simply urea in water.

The harm starts once it's sucked through your pump — it won't ignite, and it will not combine with diesel.

A drain and a thorough flush, done where the vehicle is around Green Hammerton, is usually all AdBlue in a diesel tank needs — if it is caught before your motor has been run.

Before anything, ring us on 0333 366 0103.

## AdBlue in your diesel tank in Green Hammerton: the first few minutes

To do:

- So nobody can turn the ignition on, pull the keys out.

- Close to moving traffic? Then put your hazards on.

- Hold on to the till receipt or the empty bottle, so you can tell us what was put in and about how much.

- Call just where you are. Quote a YO26 8 postcode or the nearest street name, and no one has to hunt for you.

Never:

- No starting your engine — not for a second, not to shift your car.

- Do not switch your ignition on. On plenty of diesels that alone runs the fuel pump.

- Adding extra diesel does not help: AdBlue settles out rather than thinning.

- Even a short way up York Road is too far to drive the vehicle.

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

At a forecourt around Green Hammerton, whether it is the Texaco or another one, ask the staff to help you roll your car clear of the pump.

Parked on your own drive? Then it remains just where it is.

## AdBlue in a diesel tank: what it does

Not your engine but the exhaust is where AdBlue is meant to go.

Kept in a separate tank, it is squirted into the exhaust stream to clean the fumes.

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

Inside a diesel tank it behaves very differently from fuel. It does not mix in.

The intake takes fuel from the lowest part of that tank, and that is exactly where AdBlue ends up: being heavier than diesel, it sinks.

Simplest of all: one that had AdBlue in Thorpe Underwood last night and has not been started since. The AdBlue waits at the foot of that tank, untouched — but it will be first through once your motor runs, ahead of any diesel at all.

It does two kinds of harm from there.

What remains when the water goes is urea, which forms crystals: they settle in narrow channels and block filters. On top of that, it attacks some metals in a fuel system, and carries on until it's cleared out.

Overnight, a car sitting in Green Hammerton with AdBlue in its lines grows worse; where it's only in your tank, it doesn't.

Water protects nothing. The high-pressure pump and each injector need diesel running through them, and so the water content harms them in its own right.

## Why is AdBlue in a diesel frequently the bigger fault?

A problem of thinned fuel is what you get after fuelling a diesel with petrol from the another forecourt nearby.

Damage just comes from driving on it. Mixed into your diesel and sitting inside your tank, it causes none.

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

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

It does not stay mixed, so it can't be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting the engine "to see" costs more here than almost anywhere else, whether the car is in Cattal or the middle of Green Hammerton.

As with petrol, there's good news.

Never run? Then the AdBlue sits only inside that tank, the simplest section of the entire system to empty, wherever your car has come to rest across North Yorkshire.

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

Many motors put the AdBlue filler alongside the diesel cap, now and then behind a single flap, and after dark the two can look the same. Nobody intends it.

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

The ways it takes place are few and familiar.

The top-up is hurried outside Green Hammerton Church of England Primary School, after the dash lit up with a warning as the kids were dropped in.

In the evening, a container goes in on a drive near Back Lane.

One more pattern: darkness, a pub car park outside The Bay Horse Inn, and someone using that flap for the first time.

Rented motors, new motors, company motors, or the second vehicle in a family with one of each: the least known cars get it most.

Same mistake, same first step — keep it switched off — wherever you are in Green Hammerton or the remainder of North Yorkshire.

## Started the motor with AdBlue in the diesel tank around Green Hammerton?

In that case, the AdBlue is no longer in the tank.

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

Watch for rough running, exhaust smoke, lost power, lights on the dash, or a cut-out — coming back from Ox Close Plantation, say, or part way across Green Hammerton.

Stop as soon as it is safe, switch off, and do not restart the vehicle to check.

With each start, more of that is pulled through.

Green Hammerton sits under 3 miles from the A1(M); if you were on it, leave by the next junction and stop safely instead of driving on.

Hopping across Green Hammerton to the car park by St Thomas’s Church is one matter; driving for York, under 10 miles away, is another, since each mile carries the AdBlue deeper in. So distance matters.

Tell us roughly how far it had come.

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

Noticed quickly, it very seldom leaves permanent damage.

## Emptying AdBlue in a diesel around Green Hammerton: what it takes

Our technicians come to your car, wherever it has stopped around Green Hammerton: a side street close to Green Hammerton Village Hall, a drive, a lay-by or a forecourt.

What was put in, about how much, plus if the engine has been run: our engineers ask first, because those shape the job.

Next, draining the tank right there takes out the polluted diesel and the AdBlue in one go.

What remains from AdBlue will not wash away by itself, and so the fuel system gets a careful flush, which counts much more with urea than with petrol.

A test of your vehicle comes at the end, after clean diesel goes in and the fuel filter gets cleaned or, where necessary, swapped.

Engine not run? In that case expect about half an hour on site for most jobs.

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

The final step is to bleed your system on new diesel.

At that point we fire it up and you set off, whether from a parking space at Cattal or a driveway in Green Hammerton.

The test before our engineers leave is that it runs properly on clean diesel.

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

Afterwards, there is the paperwork for the insurer: a VAT invoice and a report from the engineer.

## AdBlue drains around Green Hammerton and across North Yorkshire

The vans that answer AdBlue call-outs in Green Hammerton also cover the locations about it, Kirk Hammerton, Tancred and Whixley among them, and most of North Yorkshire beyond, across the YO postcode area.

Guessing won't help by a county line or somewhere hard to pin down; phone and ask.

Wherever your car sits — a driveway at home, a side street, a car park, a filling station — our technicians empty it on the spot, and there's no need to bring it to us; that suits Green Hammerton, a village, well.

## AdBlue in a diesel tank in Green Hammerton: the cost of fixing it

Since each callouts differ, a flat figure wouldn't be fair.

Three things shift the cost: whether the motor has been running and for how long, how much AdBlue was put in, and where the vehicle is. That last one turns on whether a technician can get to it safely, and an open drive is easier than a tight space behind St John the Baptist.

That's why every call from Green Hammerton starts with the same three queries, asked before giving a figure, not after: what got in, how much, and if it's run.

Those replies turn a range into a straight quote.

You hear that quote on the phone, before anyone heads out, and you pay on the day, by card or by phone, with nothing upfront.

Misfuelling cover is part of plenty of insurance policies, so it pays to look at yours before the van gets there.
