AdBlue in the Diesel Tank in Glandwr, and What to Do Next
What to do about AdBlue in a diesel tank depends on one thing more than any other: whether the motor has run since it was put in. Anywhere the car stands — Cwm-nant-gwynt, Glandwr — never start a motor that has not been started yet. Ring 0333 366 0103 with the ignition and motor both off. In Glandwr, that is typically drained and cleaned where it stands. If it's run, stop as soon as it is safe then switch off. Step one remains the same, even though the work is bigger.
Compare your case to a situation from the ones below, wherever across Blaenau Gwent you are.
At the pump in Glandwr: AdBlue in a diesel
Only now, bottle yet in hand, you realise that the cap you opened was the wrong one, there at the pump. Maybe you're at the Texaco, maybe at the Tesco, possibly somewhere else in Glandwr.
What it means: this is the best location to find out. The AdBlue is inside the tank and nowhere else. Nothing has drawn it in.
What to do: do not get back in and crank it to clear the petrol pump. Phone us from the forecourt after your vehicle is in a space — the attendants will lend a hand to roll it — then keep the bottle. Draining it right at the petrol pump is fine when it cannot be shifted, because the equipment is explosion-proof.
Glandwr, at home: AdBlue in your diesel tank
On the dash, a warning had been lit for days. Bought a container, poured it in outside the house, recycled the empty — and at that point checked the cap a second time, after the fact. It happens on driveways just off Glandwr Industrial Estate as commonly as anywhere.
Put simply: if your vehicle has not been driven since, it is almost as good as spotting it at the forecourt. As it is reluctant to blend, AdBlue settles to the base in the tank and waits. One night parked changes nothing.
Next: stop any early-morning move by keeping the keys in the house, then phone us. Our engineers drain it on your driveway, whether that is in Glandwr or out in Brynithel. Our pumping kit works quietly enough that it won't wake the neighbours at night.
Glandwr: drove off with AdBlue in a diesel?
You filled up, set off, and a mile or two later your engine began to run unevenly, smoke, lose power or light up the dashboard. It might have been heading for Newport, under 15 miles away, or simply down Y Graig View.
Meaning? The fuel pump has sucked the AdBlue in. Mileage decides how far it goes: filter and lines first, then the injection pump and each injector. More miles, more starts: further it travels.
Pull in somewhere safe — that is the first step — then turn everything off. Leave at the first junction — not the services beyond — if you are on the M4, under 10 miles from Glandwr. Starting it again to test gets nothing — AdBlue never clears on its own. Call us and say how far you travelled.
Hire, lease or company car with AdBlue in the wrong tank
A week ago, it was new to you. The AdBlue filler is right beside the diesel one, which you didn't know, since your own car either has no AdBlue or keeps it somewhere else. Any driver, anywhere in Blaenau Gwent, could make it.
The point: just as above, split by whether it ran, only with one added step. Work on your vehicle frequently needs the owner's go-ahead under rental or company agreements.
Do this: hire firm or your fleet manager to begin with, us next, since sorting it early saves time. If you are stuck in the car park at Llanhilleth, or by Brynithel Community Centre, whilst you wait for an answer, leave the car off.
AdBlue in your diesel tank? Not sure, in Glandwr
"I think so" is often the most honest as it gets. A slight ammonia-like whiff lingers near your filler, the bottle seems too light, and which cap came off is hard to recall. It might have been at a friend's driveway in Trinant, or rushing outside the local primary school on the school run.
Meaning? Drips outside the inlet never touch your engine at all. If it's inside your diesel tank, though, that changes. If there is AdBlue in the tank, starting the car will pull it in, and it wouldn't tell you which either.
What to do: treat it as if it was put in. Do not fire it up. Phone and give what you saw: we would rather confirm a clean tank than drain one once the engine has been run.
Glandwr: what every AdBlue drain has in common
Whichever scenario you are in, the job starts the same way. Filling station, drive, Trinant Sports & Social Club's car park or a street by Trinant Community Centre — our van reaches the vehicle, and three questions come next: which liquid, which quantity, and whether it ran. Over the phone, before anything else, you are told our quote, and those replies shape the work too.
AdBlue forms crystals and eats at some metals used in fuel systems, so it does not wash out on its own; that is why the flush, after the drain, counts much more here than with petrol. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Most unstarted cars are a half-hour job after the moment our engineers get there.
Firing it up comes at the end. Our check that it runs smoothly on new diesel comes before our engineers leave. The entire job is done where the vehicle is, and if it's noticed early, permanent damage is very unusual. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Dig out your insurance while we arrive: cover for misfuelling comes included in many policies.
