# What Now? AdBlue in the Diesel Tank in Brynglas

What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the motor has run since it went in.

Over in Marshes or here around Brynglas, an unstarted motor should stay unrun.

Ring 0333 366 0103 with the ignition and engine still off. In Brynglas, such a case is typically emptied and cleaned on the spot.

Pull over the moment you safely can then turn off, if it has been run.

The job is bigger, yet the first stage is the same.

Anywhere across Newport it took place, one of the cases below fits yours.

## Brynglas forecourt: AdBlue in a diesel at the pump

Picture it: standing by the petrol pump, holding the nozzle, you spot the cap you opened wasn't the right one.

Anywhere in Brynglas, then — Sainsbury's, Shell, or somewhere else close by.

Meaning? Finding out here is the best it gets.

The AdBlue is in the tank and nowhere else. Nothing has pulled it in.

Do this: stay out of the driver's seat, even if the pump needs clearing.

Phone us from the forecourt once the car is in a space — the attendants will lend a hand to roll it — and keep the bottle.

Emptying it there at the petrol pump is possible if it cannot be moved, since the equipment is explosion-proof.

## AdBlue in the diesel tank on a Brynglas drive?

For days the dashboard had been warning you.

Picked up a container, poured it in outside the house, binned the empty — and only then checked the cap again, after the fact.

Houses just off Bryn Bevan are hit as much as anywhere else.

Meaning? As long as your car has not moved since, it's second to the forecourt case.

Diesel and AdBlue keep apart: the AdBlue settles to the base of that tank and remains put, no matter how long the night.

What to do: leave the keys inside the house so nobody moves your car in the morning. Then ring.

Out in Crindau or here in Brynglas, the draining is done at your driveway.

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

## On the road around Brynglas with AdBlue in a diesel

Rough running, smoke, lost power or a lit dashboard started a mile or two beyond the top-up.

Possibly it was on Brynglas Tunnel, maybe on the way out towards Newport, under 3 miles away.

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

Past the filter, along the lines, and — the more the distance — deeper into the injection pump and every injector.

It goes further with each mile driven and each restart.

What to do: pull over where it is safe to do so then switch off.

On the M4, under a mile from Brynglas, that means the next junction, not the services further on.

Starting it again to test achieves nothing — AdBlue doesn't clear itself.

Let us know the mileage driven as you call.

## A hire or company car with AdBlue in the wrong tank?

You have just had this vehicle a week.

Unbeknown to you, the two fillers sit side by side here — unlike your own car, which has none or keeps it in another spot.

Throughout Newport, nobody is immune.

Put simply: an extra stage on top of the situations above, and those depend on if it has run.

Many rental and company contracts require the owner's sign-off before repairs.

Your move: hire firm or fleet manager to begin with, us next, since settling it early saves time.

Stranded near All Saints Community Church or outside Newport (South Wales) till the firm answers, your vehicle remains turned off the whole time.

## Brynglas: unsure whether it was AdBlue in your diesel tank?

At times, "I think so" is all anyone can honestly say.

A faint ammonia-like smell lingers near your filler, the bottle feels too light, and which cap came off is hard to recall.

A hurried stop by the gates of the local primary school, or a visit to a friend in East Usk: either fit.

Meaning? Drips around the inlet don't reach your engine at all.

The diesel tank with AdBlue inside is another story.

Turning on the vehicle cannot tell you which, and if there is AdBlue in the tank it will draw it in.

What to do: treat it as if it was put in. Don't start it.

Describe what you saw on your phone. A clean tank checked counts as a better outcome than a run one drained.

## Every AdBlue drain around Brynglas shares these steps

The job begins identically, whichever your situation.

Anywhere your vehicle is — Lyceum Tavern's car park, a street by Blaen-y-Pant Community Centre, a drive, a forecourt — the van gets there and asks about the liquid, the amount, and if the motor has turned over.

Answers shape the work; the price follows on the call whilst no one has set off yet.

Emptying that tank comes next, then a careful flush — more vital with urea than after petrol, since crystals and corrosion will not clear by themselves, however long it sits.

Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested.

The majority of unstarted cars are a half-hour job from the moment our technicians arrive.

Firing it up comes last.

Our test that it runs smoothly on new diesel comes before we head off.

Permanent damage is very unusual if it's noticed soon, and the whole job is done where the vehicle is.

Nothing is paid upfront, settlement happens on the day, and you get what the insurer wants: an engineer report plus a VAT invoice.

Many policies include misfuelling, and so look at yours as we head over.

## AdBlue drains across Newport, Brynglas included

Malpas and Barrack Hill get the same teams as Brynglas, a residential suburb, plus other towns over NP postcodes.

The location is clearest from a postcode beginning NP20 5.

Stopped heading to Kimberley Park, or bang in the centre of Brynglas, your vehicle remains where it is — there is no need to move it anywhere.

The van empties it where it stands.

If you're somewhere hard to describe, close to Malpas Community Centre or close to a boundary, ring and ask rather than guessing.
