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

Everything turns on one fact: if the motor has started after the AdBlue was added — far more than anything else.

If it hasn't, keep it that way, whether your car is in Gorseinon itself or out in Grovesend.

Ring 0333 366 0103 with your key and engine both off. Across Gorseinon, such a case is typically emptied and flushed where it stands.

Already started? Stop once you safely can, then turn everything off.

Step one remains unchanged, even though the work grows.

Wherever across Swansea it happened, one of the situations below matches yours.

## At the petrol pump around Gorseinon: AdBlue in a diesel

Imagine it: standing by the petrol pump, holding the nozzle, you realise the filler you opened was not the correct one.

Perhaps you are at the Asda, perhaps at the Murco, maybe somewhere else in Gorseinon.

The point: of all places to find out, the forecourt is the best.

The AdBlue is inside that tank and nowhere else. Nothing has sucked it in.

Next: avoid the urge to fire it up just to free up the petrol pump.

Ask the staff to help you roll the car into a parking bay, keep your receipt or the bottle, and call us from the forecourt.

Emptying it there at the pump is fine when it cannot be moved, since the equipment is explosion-proof.

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

On the dash, a reminder had shown for days.

Only by the recycling, the empty container in your hand, did you look back at the cap you had opened on the driveway.

It happens on driveways just off Pontardulais Road as regularly as anywhere.

Meaning? Provided the vehicle has not been driven since, it's close to the forecourt case.

As it is reluctant to blend, AdBlue drops to the base inside that tank and waits. A night parked changes nothing.

What to do: leave your keys inside the house so no one moves the vehicle in the morning. Then call.

Your drive is where it gets drained, whether around Gorseinon or Penyrheol.

Even at night, our pumps stay quiet enough for a driveway.

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

You filled up, set off, and a mile or two later your motor began to run unevenly, smoke, lose power or light up the dashboard.

Maybe it was on West Street, perhaps on the way out towards Swansea, under 10 miles away.

Meaning? Your fuel pump has taken the AdBlue up.

Through the filter, along the lines, and — the more the distance — on into the injection pump and every injector.

Each mile and each restart takes it further.

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

Gorseinon lies under 3 miles from the M4; there, pull off at the first junction instead of pressing on for the services.

It won't have cleared, and so there is no point starting it again to find out.

Call us and say how far you drove.

## AdBlue in the wrong tank of a hire, lease or company car

It is a vehicle you have had for a week.

Your own vehicle either does without AdBlue or puts it elsewhere, so no one warned you the AdBlue cap was right beside your diesel.

Anywhere you are across Swansea, any motorist could be caught.

Meaning? Whatever case above counts too — run or not — plus one extra stage.

Plenty of hire and company contracts require the owner's approval before repairs.

Next: ring the rental company or the fleet manager first, then us — sorting it before our arrival is faster.

Stranded by Gorseinon Library or outside Gowerton until the firm answers, your car stays switched off the whole time.

## AdBlue in your diesel tank? Not sure, around Gorseinon

Honestly, the best answer might be that you think it did.

Which cap was taken off, you cannot recall; meanwhile the bottle feels lighter than expected, and a whiff of ammonia hangs by your filler.

Maybe at a friend's driveway in Penllergaer, or rushing outside the local primary school at the school run.

The upshot: the motor is not harmed by a little AdBlue splashed around the outside.

A diesel tank with AdBlue inside is another story.

If there is AdBlue in your tank, turning on your car will pull it in, and it wouldn't tell you which either.

Assume it got in, and never start your key.

Ring and give the details: we would sooner confirm a clean tank than drain one once your engine has run.

## The common ground in every Gorseinon AdBlue drain

Whatever the case, one opening is used.

Anywhere the car is — The Mardy Inn's car park, a road by Tabernacle, a drive, a forecourt — the van gets there and we ask about the liquid, the quantity, plus whether the engine has turned over.

Over the phone, ahead of dispatch, you hear our quote, and those answers shape the job too.

A thorough flush follows this drain. With petrol it is standard; with AdBlue it's crucial, because crystals build up and certain metals are attacked, and neither washes out unaided.

Next comes your filter — flushed, or replaced when needed — followed by fresh diesel, and a test of the car.

Never started? In that case roughly half an hour on site is most jobs.

Starting the engine comes last.

With fresh diesel in, it runs while we check it's running smoothly, and then we head off.

If it's caught early, the vehicle very rarely has long-term damage, and the whole job takes place where it is.

Paying comes on the day, never in advance. For the insurer, there is a VAT invoice plus a written report from the engineer.

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

## Gorseinon and Swansea: AdBlue drains across the area

As a coastal town, Gorseinon has the same vans as the surrounding towns — Loughor, Gorseinon Garden Village — right through SA postcodes.

The location comes quickest from a postcode that starts SA4 4.

Central Gorseinon or a lay-by towards Argyll Gardens: either way it sits, your car doesn't need to move an inch for us.

Where it stands, that is where it gets emptied.

Ring and check rather than guess when you are close to Gorseinon Gorsedd Circle, on a border, or somewhere tricky to explain.

## Your scenario, summed up

Where it has not started, ring then leave it that way.

Whichever case applies, Petrol in Diesel handles from there on 0333 366 0103, across Swansea and in Gorseinon — after you pull over, turn off then phone, if it has run.
