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

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 was put in.

Over in Ogmore Vale or here around Pontycymer, an unstarted engine must stay that way.

Leave the engine and the ignition off then ring 0333 366 0103; it is normally a drain and a thorough flush, done where the car is around Pontycymer.

Already started? Pull over once safe, then switch everything off.

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

Match your case to a situation from the list below, anywhere across Bridgend you are.

## At the pump in Pontycymer: AdBlue in a diesel

Just at this point, nozzle still in your hand, you realise that the cap you took off was the wrong one, there at the pump.

Anywhere around Pontycymer, then — the nearest petrol station, Oils for Wales, or anywhere else close by.

The upshot: of every spot to find out, the forecourt is the best.

Nothing has drawn it in, and so the AdBlue sits only in the tank.

Your move: stay out of the driver's seat, even if the queue needs clearing.

Have the attendants to lend a hand pushing it into a space, save the bottle, then ring us from there.

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

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

Several days had passed with the dash light on.

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

Drives near Oxford Street get it as much as anywhere.

What it means: if you haven't driven since, this is almost as good as the forecourt.

Being unable to mix, AdBlue drops to the base in that tank and stays. One night standing changes none of that.

Next: stop an early drive by keeping your keys in the house, then phone us.

We drain the car on your drive, whether that is around Pontycymer or out in Blaengarw.

The pumps are quiet enough to use outside a house after dark.

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

Filled up, drove away, and soon your engine was turning roughly, smoking, losing power, or lighting up your dash.

Maybe driving to Swansea, under 25 miles away, or just along Commercial Place.

What it means: the fuel system has pulled the AdBlue in.

Past the fuel filter, through the lines, and — the further the mileage — on into the high-pressure pump and every injector.

It travels further with every extra mile driven and every restart.

Do this: stop anywhere safe, then switch your engine off.

Exit by the next junction — not the services further along — if you are on the M4, under 10 miles from Pontycymer.

Starting it again to test achieves nothing — AdBlue never clears on its own.

Let us hear the mileage driven as you ring.

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

You have had this car barely a week.

Unknown to you, the two fillers sit next to each other here — unlike your own vehicle, which has none or keeps it elsewhere.

Throughout Bridgend, no one is immune.

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

The owner often has to sign off the work, under plenty of rental and fleet contracts.

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

Stranded by Garw Valley Life Centre or outside Garth (Mid Glamorgan) until the firm replies, the car remains switched off throughout.

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

Now and then, "I think so" is the most you can honestly say.

Which cap was taken off, you cannot say; meanwhile the bottle feels lighter than it ought to, and a whiff of ammonia lingers by your filler.

The gates of the local primary school in a hurry, say, or a friend's driveway over in Tylagwyn.

Meaning? Spills around the inlet don't touch your motor at all.

AdBlue inside your diesel tank does.

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

Take it that it was put in, and don't turn the key.

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

## The common ground in every Pontycymer AdBlue drain

The work opens the same way, whatever the case.

Filling station, driveway, The W.E.X.A.'s car park or a road by St David's — the van comes to the vehicle, and three answers follow: which liquid, what amount, and whether it ran.

Answers set the job; the quote follows on the call whilst no one has left yet.

A thorough flush follows this drain. With petrol it is routine; with AdBlue it's essential, because deposits form and some metals corrode, and none of it washes out unaided.

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

Most unstarted vehicles are a half-hour visit from the moment our technicians turn up.

The last step is starting the car.

Before our engineers head off, it's checked to confirm it runs properly on fresh diesel.

Long-term damage is very unusual when it is noticed quickly, and the whole job is done where the car is.

You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer.

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