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

Motor off, ignition off: that's how you start if AdBlue has gone into your diesel tank.

Urea dissolved in water is what AdBlue is.

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

Caught before your engine has run, AdBlue in a diesel tank is generally a drain and a thorough flush, done where the vehicle is in Ellacombe.

Nothing comes before ringing 0333 366 0103.

## AdBlue in your diesel tank in Ellacombe: the first few minutes

To do:

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

- Put the hazard lights on if you're at all close to moving traffic.

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

- Give us a postcode starting TQ1 1, or whatever street is nearest, and our van reaches you straight — so call from wherever you are.

Things not to do:

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

- Plenty of diesels power their pump the instant the ignition goes on, and so keep the vehicle off.

- Pouring in extra diesel does not work: AdBlue separates out instead of blending.

- Keep the vehicle where it is rather than driving it anywhere, even a short distance along Lower Ellacombe Church Road.

- Don't try to drain it yourself by the kerbside.

At a forecourt in Ellacombe, whether it's the Harvest Energy or another one, ask the staff to help you push the vehicle clear of the pump.

If you're on your own drive, leave the vehicle exactly where it stands.

## What AdBlue does in a diesel tank

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

From a dedicated reservoir it goes directly to the exhaust, treating what the motor lets out.

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

Fuel blends; AdBlue, after tipped in, won't. The behaviour is nothing like diesel's.

It's heavier than diesel, and so it sinks and gathers at the bottom of your tank, which is where the pickup sucks fuel from.

A motor topped up on a driveway in Babbacombe yesterday evening and left unstarted is the straightforward case. Nothing has pulled the AdBlue up yet — but when your motor turns, that is what is pulled first, straight from the bottom of that tank.

From there it does two kinds of damage.

As its water goes, the urea left behind crystallises, and the crystals block filters and settle in fine passages. And it is corrosive to some of the metals a fuel system is made from, and so it keeps working on the components it reaches for as long as it stays there.

A car left sitting in Ellacombe with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank is not.

Then there's the water: it offers no protection to the components that rely on it the most — the injection pump and each injector.

## AdBlue in a diesel: why it's often worse than petrol

Petrol put into a diesel on Esso's forecourt makes your fuel watery — that's the main issue.

Harm just comes from running on it. Mixed into the diesel and left inside that tank, it causes nothing.

AdBlue in a diesel is a different matter: not thin fuel, but no fuel at all.

Not burning, it cannot just be run through.

Crystals and corrosion stay through the following tankful, and AdBlue separates again out of your diesel, and so watering it can't work. Hence the flush counts so much, and trying your engine "to see" costs more with AdBlue than almost any other slip — in St Marychurch or the centre of Ellacombe equally.

The good news is the same as with petrol.

Wherever across Devon your vehicle has stopped, an unrun motor leaves the AdBlue still in the reservoir: the simplest part of a fuel system to clear.

## How AdBlue ends up in a diesel tank around Ellacombe

It's not deliberate. Plenty of cars have the AdBlue inlet beside the diesel one, now and then under a single flap, and muddling them up is simple in poor light.

Mostly it's not the forecourt: someone buys a container heading home and pours it in at home.

It tends to occur in a couple of familiar ways.

The refill gets hurried outside Ellacombe Church of England Academy, after your dash flashed with a warning while the kids were taken off.

Someone tips the container in outside their house, right off Ellacombe Church Road, as the day ends.

Else, in dim light by Twiggies, your vehicle gets topped up by a driver using that flap the first time.

It takes place most in the cars drivers know least: a hire car, a new car, a company car, or the second motor of a household with one diesel and one petrol.

Anywhere around Devon, Ellacombe included, the slip doesn't change, and nor does the first step: keep it off.

## Started the motor with AdBlue in the diesel tank around Ellacombe?

The AdBlue has left the tank, then.

The fuel filter and lines have had it sucked along, and any running time carries it on to the injection pump and every injector.

Watch for rough running, smoke, falling power, warnings on the dash, or a stall — returning from Brewery Park, perhaps, or midway across Ellacombe.

No restarting to check: stop once it is safe, then switch it off.

Each start pulls more of it through.

Ellacombe lies under 15 miles from the M5; if you were on it, exit at the first junction and pull up safely instead of driving on.

How far it went counts. A couple of hundred yards across Ellacombe to the car park by Christ Church Ellacombe is a very different job from a run towards Exeter, under 25 miles away, with the AdBlue reaching further into the system with each mile.

Tell us about how far it had come.

Wherever the vehicle came to a stop is where all of it gets done, even with more to clean out after the engine has been run.

Long-term damage is very uncommon if it's spotted quickly.

## What emptying AdBlue from a diesel involves around Ellacombe

A street beside Plainmoor, a driveway, a layby or a forecourt: wherever your car has stopped in Ellacombe, we come to it.

What got in, roughly the quantity, and whether the motor has turned over: our technicians ask before all else, since those decide the work.

The contaminated diesel and the urea come out together when your tank is drained, on the spot.

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

The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested.

Roughly half an hour once we arrive is typical for most jobs where your motor hasn't run.

Low-noise enough for use outside a house at night, and safe on a working forecourt, the pumps are explosion-proof.

Priming the fuel system with clean diesel comes last.

You drive off as soon as our technicians have started the car, and it makes no difference whether your car is on a drive in Ellacombe or in a space by Torre.

Before we leave, we check it is running properly with new diesel in.

No garage is required at any stage, with the whole job done on the spot.

You get a VAT invoice and an engineer report afterwards, which is what insurers ask for.

## About Ellacombe, briefly

Ellacombe is a suburban area in Devon, situated near the coast and approximately 17 miles from Exeter. Ellacombe has a mix of housing types, but is predominantly characterized by terraced homes. Ellacombe sits at an elevation of 52 metres, overlooking the surrounding landscape. Ellacombe is close to nearby places such as Torquay, Plainmoor, and Upton, and is about 164 miles from London.

## AdBlue drains across Devon, Ellacombe included

Torquay, Plainmoor and Upton are among the towns around Ellacombe that the same vans reach, together with most of Devon further out, throughout the TQ postcode area.

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

Ellacombe is a residential suburb, and a mobile drain suits it: whether the vehicle is on a home drive, a residential street, a car park or a forecourt, our technicians drain it where it stands, so it never needs to be shifted to us.

## What AdBlue in a diesel tank costs to put right in Ellacombe

There is no fair single price, because the jobs are not the same.

Three things shift the price: whether the engine has run and for how long, how much AdBlue went in, and where your car is. That last one turns on whether a technician can reach it safely, and an open drive is easier than a tight spot behind Indoor market.

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

Those answers turn a range into a straight price.

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

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

## In Ellacombe and still next to the car?

In that case, touch nothing — that's the best move available.

Ignition off, motor off, keys out.

Say it's AdBlue, roughly how big an amount, and whether it ran, on 0333 366 0103. From there Petrol in Diesel takes over, in Ellacombe or wherever in Devon.
