# AdBlue in the Diesel Tank in Okehampton, and What to Do Next

Has your motor turned over since the AdBlue got in? That one question decides almost everything about what comes next.

Over in Folly Gate or here around Okehampton, an unstarted engine must stay unrun.

Phone 0333 366 0103 with the key and engine still off. In Okehampton, such a case is generally drained and cleaned on the spot.

Already run? Pull over once you safely can, then switch it off.

Step one stays the same, even though the job grows.

Find the situation below that matches yours, wherever in Devon it happened.

## On a Okehampton forecourt with AdBlue in a diesel

Only at this point, nozzle still in your hand, you realise that the cap you opened was the wrong one, right at the pump.

It might be the MacCullock's Garage, or the Fuelling point, or a different station around Okehampton.

In short: no better spot to be to discover it.

Just your tank holds AdBlue; no component past it has drawn it in.

Freeing the petrol pump is no reason to run it — so don't get back in.

Ask the attendants to help you roll the vehicle into a parking bay, keep your receipt or the bottle, and ring us from the forecourt.

Can't move the car by the petrol pump? Explosion-proof equipment makes a live forecourt safe, and so it can be drained in place.

## At home in Okehampton with AdBlue in the diesel tank

For days the dash had been warning you.

Only at the recycling bin, the empty bottle in hand, did you glance back at the cap you'd used on the driveway.

It happens on driveways just off George Street as often as anywhere.

Meaning? Provided the car hasn't moved since, it is second to the forecourt case.

As it is reluctant to mix, AdBlue drops low in that tank and stays. A night parked alters none of that.

Keep your keys indoors overnight — or a person may take it off at breakfast — and phone us.

We drain the vehicle on your drive, whether that's in Okehampton or out in Chichacott.

Even at night, the pumps are quiet enough for a driveway.

## Okehampton: set off with AdBlue in a diesel?

A mile or two after topping up, your engine began playing up: roughness, smoke, lost power, lights on the dash.

Maybe driving to Exeter, under 25 miles away, or just down Market Street.

Meaning? The fuel pump has sucked the AdBlue up.

The high-pressure pump and each injector get it as well on a bigger run, after the fuel filter and lines have it.

More driving, more restarts: further it goes.

Do this: stop somewhere sensible, then switch your engine off.

Okehampton lies under 25 miles from the M5; on it, come off at the first junction rather than pressing on for the services.

Starting it again to check gets nothing — AdBlue doesn't clear on its own.

About how far did it gone? Say so when you phone.

## Hire, lease or company car with AdBlue in the wrong tank

It's a vehicle you have had for a week.

On your own vehicle, AdBlue is missing or elsewhere. On this one, its cap is right by your diesel cap — news to you.

Wherever you happen to be around Devon, every motorist can be caught.

In short: one extra step on top of the situations above, and those depend on if it's run.

Many hire and company contracts want the owner to approve work on the car.

Your move: hire firm or your fleet manager to begin with, us second, because sorting it early saves time.

Keep the car off as the reply comes, whether you're waiting at the nearest station or close to Town Hall.

## AdBlue in the diesel tank? Not sure, in Okehampton

"I think so" is often as honest answer there is.

What cap came off, you can't recall; but the bottle weighs less than it ought to, and ammonia hangs by your filler.

It might have been at a friend's drive in Padson, or rushing by Okehampton Primary School and Foundation Unit on the school run.

What it means: a little spilled round your filler does no harm to your motor.

AdBlue inside the diesel tank does.

You cannot tell which by turning the ignition, and doing so will pull in any AdBlue that is in your tank.

What to do: treat it as if it got in. Don't crank it.

Call us and explain what you saw; we'd rather check a tank that turns out clean than drain one that has already been run.

## The common ground in every Okehampton AdBlue drain

Whatever the situation, a single start applies.

Anywhere your vehicle stands — The Plume Of Feathers's car park, a road by New Carlton Cinema, a drive, a forecourt — our van arrives and we ask about the fluid, the amount, plus if the motor has been run.

Answers set the job; the price follows by phone whilst no one has left yet.

Then the tank is emptied and the fuel system cleaned thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not rinse out on its own.

Clean diesel goes in once the filter is flushed or replaced, and the car is then tested.

Where the motor has not been started, expect roughly half an hour on site, for most cases.

Firing it up comes at the end.

With clean diesel in, it runs while our technicians check it's running smoothly, and then we leave.

Our engineers do the entire job where the car is, and permanent damage is very rare when it has been spotted quickly.

Paying is on the day, never in advance. For the insurer, you get a VAT invoice and a written report from the engineer.

Many insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way.

## About Okehampton, for a moment

Okehampton has a population of approximately 8187 people, according to recent estimates.

## AdBlue drains around Okehampton and across Devon

Being a riverside town, Okehampton has the same vans as the surrounding places — Brightley, Stockley Hamlet — all the way across EX postcodes.

A postcode starting EX20 1 is the quickest way to tell us where you are.

Parked en route to Simmons Park, or bang in the centre of Okehampton, your car stays where it is — there's no need to move it at all.

Our van empties it in place.

Awkward to explain? Close to Museum Of Dartmoor Life or a county line? Checking beats assuming, and so phone.

## In one line: your situation

Not run yet: keep the car off then call.

Run already: pull over, power down, ring 0333 366 0103. Petrol in Diesel handles the rest, in Okehampton or wherever in Devon.
