# AdBlue in the Diesel Tank in Garvetagh: What Now?

One thing matters above all when AdBlue is in a diesel tank, and it is if the engine has been started since.

Wherever your vehicle is — Erganagh, Garvetagh — never start an engine that has not run yet.

Keep nothing on, call 0333 366 0103, then count on a proper flush plus a drain, done right where your vehicle sits in Garvetagh.

When the engine has been run, stop somewhere safe first, then turn the vehicle off.

The job is bigger, but the first step is the same.

Below: the situations we see, wherever around County Tyrone. Pick the one that fits.

## On a Garvetagh forecourt with AdBlue in a diesel

The cap you unscrewed was the wrong one — and you just spot it while you are stood at the petrol pump, bottle or the nozzle in your hand.

It might be the the nearest petrol station, or perhaps the another forecourt nearby, or another forecourt around Garvetagh.

Meaning? Spotting it on the forecourt is as good as it can be.

No pump has pulled it through, so the AdBlue sits only in that tank.

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

A few jobs: a shove into a bay with the attendants helping, the bottle kept, and a call to us from where you stand.

The equipment is explosion-proof and safe on a live forecourt, and so a car that can't be pushed away gets drained right at the pump.

## Garvetagh, at home: AdBlue in the diesel tank

Days had passed with the warning light on.

A bottle bought at the garage, tipped in at the driveway — and it's just at the recycling that the cap caught a second look.

It happens on drives just off Crown Street as regularly as anywhere.

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

At the bottom of that tank is exactly where AdBlue stays, because it won't mix with diesel — and a night passing changes nothing of the difference.

Next: stop any early drive by keeping your keys indoors, then ring us.

Our engineers drain the vehicle on your driveway, whether that is around Garvetagh or out in Castlederg.

The pumps are quiet enough to use outside a house at night.

## On the road in Garvetagh with AdBlue in a diesel

A mile or two beyond filling up, the engine started playing up: roughness, smoke, less power, lights on your dash.

It might have been driving to Derry, under 25 miles away, or simply along Crom Street.

What it means: the system has sucked the AdBlue in.

It's been through the filter and the lines and, the further you went, into your high-pressure pump and the fuel injectors.

Each mile and each restart takes it further.

What to do: pull over where it's safe to do so and switch off.

On the M77, over 50 miles from Garvetagh, that means the next exit, not the services further on.

Don't restart it to see if it has cleared; it will not have.

About how far did it go? Tell us as you call.

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

You've had the car hardly a week.

Your own vehicle either has no AdBlue or keeps it elsewhere, and so no one told you the AdBlue cap was right beside your diesel.

It can happen to anyone, anywhere across County Tyrone.

What it means: the same as the scenarios above, depending on whether it has run, with one more step.

Work on your vehicle frequently needs the owner's approval under rental or fleet agreements.

Do this: rental firm or your fleet manager first, us second, since settling it beforehand saves time.

If you're stuck in the car park at the nearest station, or by the centre, whilst you wait for an answer, leave the car off.

## Garvetagh: unsure if it was AdBlue in your diesel tank?

Honestly, the best answer might be that you think so.

The bottle is lighter than it should be, there's a faint smell of ammonia around the filler, and you cannot remember which cap you took off.

Possibly it happened in a hurry at the school gates at the local primary school, or on a friend's drive in Killeter.

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

AdBlue inside the diesel tank does.

If there is AdBlue in your tank, starting the car would suck it in, and it would not tell you which either.

Next: act as though it went in, and leave the motor off.

Ring us and explain what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run.

## The common ground in every Garvetagh AdBlue drain

Each situation has the same start to the work.

Wherever the vehicle stands — the pub in the village's car park, a street by a street just off the centre, a drive, a filling station — our van gets there and asks for the liquid, the quantity, plus whether your engine has been run.

Answers set the work; the quote comes on the call whilst nobody has left yet.

A thorough flush comes after this drain. With petrol it's routine; with AdBlue it's crucial, because crystals build up and certain metals corrode, and neither rinses away unaided.

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

Not started? In that case roughly half an hour on site covers most jobs.

Starting it comes last.

Before our technicians go, it's tested to be sure it runs correctly on new diesel.

When it's caught early, the car very seldom has long-term damage, and the entire job happens where it is.

For your insurer: the engineer's report and the VAT invoice. For you: payment that day, no money in advance.

Worth remembering: many insurers offer misfuelling cover, and so a check of your documents as we travel pays.
