# What Now? AdBlue in the Diesel Tank in Cilfrew

Has your engine turned over since the AdBlue got in? This single point settles nearly everything else from here.

Not run so far? Then leave the vehicle like that, wherever your car sits — Cilfrew or Llantwit.

Switch nothing on, phone 0333 366 0103, then count on a proper flush after a drain, carried out just where the vehicle stands in Cilfrew.

Already run? Stop once you safely can, then switch everything off.

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

Match your case to a situation from the list below, wherever in Neath Port Talbot you happen to be.

## On a Cilfrew forecourt with AdBlue in a diesel

You're at the pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one.

Anywhere in Cilfrew, then — Morrisons, Tesco, or somewhere else nearby.

What it means: this is the ideal place to find out.

Still inside that tank, with no fuel pulled through: that's where the AdBlue is.

Next: resist the temptation to start it just to move away from the petrol pump.

Ring us from the forecourt once the vehicle sits in a bay — the attendants will help push it — and keep the bottle.

Draining it there at the petrol pump is possible when it can't be shifted, since the equipment is explosion-proof.

## AdBlue in your diesel tank at home around Cilfrew

On the dash, a reminder had shown for days.

A bottle bought at the garage, emptied in on the drive — and it's just by the recycling that the cap caught a second look.

Homes just off Penscynor are caught out as much as everywhere else.

What it means: if you have not driven since, this is nearly as good as the forecourt.

At the bottom of your tank sits exactly where AdBlue stays, because it will not blend with diesel — and a night going by changes no difference.

Next: prevent any early-morning move by putting your keys in the house, then ring us.

Your drive is where it is drained, be it in Cilfrew or Aberdulais.

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

## Cilfrew: drove off with AdBlue in a diesel?

A short way after topping up, your motor began misbehaving: roughness, smoke, less power, lights on the dash.

Maybe driving to Swansea, under 10 miles away, or just along March Hywel.

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

The high-pressure pump and every injector see it as well on a bigger trip, once the fuel filter and lines have had it.

Every restart, like every mile, pushes it deeper.

Do this: pull up anywhere sensible, then turn your engine off.

Cilfrew sits under 5 miles from the M4; there, pull off at the next junction instead of pressing on for the services.

It will not have cleared, and so there is no point restarting to find out.

Tell us know the distance covered when you call.

## AdBlue in the wrong tank: hire, lease and company motors

You have had the vehicle barely a week.

On your own vehicle, AdBlue is missing or somewhere else. On this one, the cap is right next to your diesel inlet — a surprise to you.

It can happen to anyone, anywhere around Neath Port Talbot.

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

Work on your vehicle often requires the owner's go-ahead under rental or company agreements.

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

Stuck near Aberdulais Community Centre or outside Neath till the firm replies, the car stays switched off throughout.

## Cilfrew: unsure if it was AdBlue in the diesel tank?

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

Too light, that bottle; a trace of ammonia round your filler; a hazy memory of the cap. Sound familiar?

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

Meaning? Spills outside the inlet never touch the motor at all.

AdBlue inside the diesel tank does.

You can't tell which by turning the key, and doing so will suck in any AdBlue that is in the tank.

Next: assume it got in, then keep your engine off.

Describe what you saw on your phone. A clean tank looked at is a happier outcome than an already-run one drained.

## Cilfrew: what each AdBlue drain has in common

Whichever situation you are in, the job starts the same way.

Anywhere your vehicle stands — Aberdulais Royal British Legion's car park, a street beside Aberdulais Tin Works and Waterfall, a drive, a filling station — the van gets there and asks about the fluid, the amount, and whether the engine has turned over.

On the phone, ahead of anything else, you are told the quote, and those replies decide the job too.

Draining the tank comes first, then a careful flush — more vital with urea than after petrol, because crystals and corrosion will not clear on their own, no matter how long you wait.

Next is the fuel filter — flushed, or swapped when necessary — followed by fresh diesel, and a test of your car.

Where your engine has not been started, allow roughly half an hour once we arrive, in most jobs.

Our engineers fire it up at the end.

Before our engineers go, it's tested to confirm it runs smoothly on clean diesel.

When it's noticed quickly, the car very seldom has long-term damage, and the whole job takes place where it is.

Paying comes that day, never in advance. For your insurer, there is a VAT invoice and a report from the engineer.

It is worth remembering: lots of insurers include misfuelling cover, so a check of your documents while we travel is worthwhile.
