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

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

Water with urea mixed in it: that is AdBlue.

It doesn't burn, it doesn't mix with diesel, and the damage it does starts when the fuel system pulls it in.

In Bulverton, AdBlue in a diesel tank caught before your engine runs usually comes down to a drain and a thorough flush, just where the car is.

Before you do anything else, phone 0333 366 0103.

## Bulverton, AdBlue in the diesel tank: what to do right away

Do these:

- Keys out — that way nobody can power anything on.

- Near moving traffic? So put the hazard lights on.

- Keep the till receipt or the empty bottle, so you can tell us what went in and about how much.

- Call us from where you are. A postcode starting EX10 9, or the name of the nearest street, brings the van to you without a search.

Do not:

- Don't start your engine, even for a moment to move the car.

- The ignition remains off: on many diesels, turning it on is enough to start the pump.

- Don't top up with diesel to dilute it. AdBlue does not mix in diesel; it separates out.

- Even a short distance up Dark Lane is too far to drive the vehicle.

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

The attendants working at any Bulverton filling station — the the nearest petrol station included — will usually lend a hand rolling it aside if you ask.

On your own driveway, do not move it at all.

## 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 your exhaust gas to fresh it.

No part inside an injection pump is made for this fluid — and no part of that was intended to go that way.

It does not blend. After it's tipped into a tank of diesel, AdBlue behaves not at all like diesel.

The intake takes fuel from the deepest part of the tank, and that is just where AdBlue settles: as it is heavier than diesel, it sinks.

Easiest of all: one that got AdBlue in Stowford last night and has not been started since. The AdBlue waits at the foot of that tank, undrawn — though it would be first through if your engine starts, ahead of any diesel at all.

Two kinds of harm come from there.

What is left when the water goes is urea, which turns into crystals: they settle in tiny passages and clog filters. On top of that, it eats at some metals in a fuel system, and carries on till it's flushed out.

Overnight, a car sitting around Bulverton with AdBlue in its lines grows worse; where it's only inside your tank, nothing changes.

The water in it causes damage of its own: the high-pressure pump and your injectors depend on diesel to lubricate them, and water gives them nothing.

## Why is AdBlue in a diesel commonly the bigger issue?

Fill a diesel with petrol by mistake at the East Budleigh Garage, and the issue is thinned fuel.

Harm just comes from driving on it. Blended into your diesel and sitting in your tank, it does nothing.

AdBlue in a diesel is another matter: not thin fuel, yet no fuel at all.

Not burning, it can't just be run through.

It does not stay mixed, and so it cannot be thinned. 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 your engine "to see" costs more here than nearly anywhere else, whether your car is in Land Part or the middle of Bulverton.

As with petrol, there's good news.

Not started? Then the AdBlue waits just inside your tank, the easiest bit of the entire system to empty, anywhere the vehicle has come to rest in Devon.

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

After dark, two caps together — the AdBlue cap and the diesel cap, now and then under one flap — may look the same. No one intends it; plenty of designs invite it.

It usually takes place at home, from a bottle bought on the journey home, rather than at the filling station.

The ways it takes place are few and familiar.

The refill gets rushed outside Sidmouth Church of England (VA) Primary School, after your dash flashed with a warning while the kids were dropped in.

Close to Bickwell Lane, a driver tips a container in at home in the evening.

Or a driver unfamiliar with that flap refills your car after dark, stopped in the car park outside The Balfour.

The least known vehicles see it most — hire cars, new ones, fleet ones, and the spare motor of a home with both fuels.

Keep it switched off: that is the first step to an identical slip, wherever in Bulverton or the remainder of Devon you are.

## Started your engine with AdBlue in the diesel tank around Bulverton?

Then your tank is no longer where the AdBlue is.

With any running time, it travels to the high-pressure pump and each injector, after passing through the filter and pipework.

Lumpy running, smoke from the exhaust, dropping power, dashboard warnings or stalling: any may appear, maybe part way across Bulverton or returning from Wheat Hill.

When you safely can, pull over then switch everything off — without turning it on again to test.

Every start pulls more of it through.

On the M5, under 10 miles from Bulverton, the next junction is where to leave, and somewhere sensible is where to park — not driving on.

Mileage matters: every mile carries the AdBlue deeper in, and so driving towards Exeter, under 15 miles away, gives a far bigger job than hopping across Bulverton to the car park by St Francis of Assisi.

About how far it had come is worth telling us.

Once the engine has been started, the flush includes more, and all of it is done where the car has stopped.

When it is spotted quickly, permanent damage is very unusual.

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

The car stays put, whether that's a road near Sidmouth Amateur Dramatic Society, a drive, a lay-by or a filling station in Bulverton, and our van comes to it.

What went in, roughly the quantity, plus whether the engine has turned over: our technicians ask first, because those decide the job.

Then your tank is emptied where the car waits, so the polluted fuel and the AdBlue come out together.

A careful flush counts far more with AdBlue than with petrol, since residue will not clear away on its own.

After that, your filter: flushed, or replaced when it has to be. After that clean diesel, then a check of your car.

The majority of these jobs are a half-hour job once our engineers turn up, if your motor hasn't run.

The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house at night.

Finally, your system is primed with fresh diesel.

Firing it up comes next, and then you drive off from where your car is parked, at Feniton or on a drive around Bulverton.

The check before we leave is that it runs correctly on fresh diesel.

We do it all wherever your car has stopped, and it never needs to go to a workshop.

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

## About Bulverton and where it is

Bulverton is a suburban area in Devon, situated near the coast and approximately 12.6 miles from Exeter. Bulverton sits at an elevation of around 65 metres, overlooking the surrounding countryside. Bulverton is characterized by its predominantly detached housing stock, with nearby places including Middle Woolbrook, Higher Woolbrook, and Lower Woolbrook. Bulverton is a relatively small community, with a population of around 1505 residents.

## AdBlue drains across Bulverton and Devon

Over the EX postcode area, the vans taking AdBlue jobs around Bulverton reach much of Devon too, Middle Woolbrook, Higher Woolbrook and Lower Woolbrook among them.

Guessing doesn't help close to a border or anywhere tricky to describe; phone and ask.

A van that comes to you suits Bulverton, a residential suburb: you have no need to bring your vehicle to us, since our technicians empty it on the spot, on a driveway, a side street, a car park or a filling station.

## What AdBlue in a diesel tank costs to put right around Bulverton

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

Whether your engine has run, and for how long, comes first in what changes the cost. How much AdBlue was put in comes next, and then the position of the vehicle, since an open drive is simpler for our van to get to safely than a tight spot behind Woolcombe Hall.

For that reason, every enquiry from Bulverton begins by asking the identical trio — which fluid went in, how much, if the engine ran — before a quote.

Those replies narrow a range down to one figure.

Our price is quoted during the call, before a van sets off; payment happens on the day, by card or by phone, and nothing upfront.

Check your insurance whilst we are on the way: plenty include misfuelling cover.

## In Bulverton and still alongside the vehicle?

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

Keys out, engine off, ignition off.

Phone 0333 366 0103 and tell us it is AdBlue, about how much, and if it's run. Petrol in Diesel takes it from there, around Bulverton or anywhere across Devon.
