Merthyr Tydfil: AdBlue in the Diesel Tank? Find Your Situation

What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the engine has run since it went in. Wherever your car is — Cae-draw, Merthyr Tydfil — never start an engine that hasn't run yet. Leave the motor and your ignition off and ring 0333 366 0103; it's generally a drain and a thorough flush, done where your car is around Merthyr Tydfil. Stop the moment it is safe and switch off, if it has already run. The job is bigger, yet the first stage is the same.

Find the scenario below that matches yours, wherever in Merthyr Tydfil it happened.

Merthyr Tydfil forecourt: AdBlue in a diesel at the pump

You are at the petrol pump, the nozzle or the bottle still in your hand, and you have just noticed the cap you opened was the wrong one. It might be the Applegreen, or perhaps the Esso, or another forecourt in Merthyr Tydfil.

Meaning? Spotting it on the forecourt is as good as it can be. No pump has drawn it in, so the AdBlue stays only in your tank.

Your move: keep out of the driver's seat, even if the pump needs clearing. Three jobs: a push into a bay with the attendants helping, the receipt saved, and a ring to us from the forecourt. If it cannot be shifted, it can be cleared at the pump: the equipment is explosion-proof and fine on a busy forecourt.

Merthyr Tydfil, at home: AdBlue in the diesel tank

On the dash, a warning had shown all week. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look a second time at the cap. Driveways near High Street get it as much as any other street.

Put simply: if your car hasn't moved since, it is almost equal to spotting it at the forecourt. At the bottom of the tank is where AdBlue stays, because it will not blend with diesel — and a night passing makes nothing of the difference.

Next: the keys indoors, so nobody drives your car anywhere at breakfast. Then, phone. Your drive is where it is emptied, whether in Merthyr Tydfil or Glebeland. The pumps are quiet enough to use outside a house at night.

On the road around Merthyr Tydfil with AdBlue in a diesel

A short way beyond filling up, the motor began playing up: rough running, smoke, less power, lights on the dash. Victoria Street, say, or the route towards Newport — a run of under 25 miles.

Put simply: the AdBlue has been pulled into the system. Mileage sets how deep it goes: filter and lines to begin with, then the high-pressure pump and every injector. More driving, more starts: deeper it goes.

Pull in somewhere safe — that is the first step — then turn everything off. On the M4, under 25 miles from Merthyr Tydfil, that means the next junction, not the services further on. It won't have cleared, so there is no point starting it again to find out. Call us and say how far you travelled.

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

It's a car you have had for a week. On your own car, AdBlue is missing or somewhere else. On this one, its cap is just by the diesel cap — a surprise to you. Across Merthyr Tydfil, nobody is immune.

In short: one extra stage on top of the situations above, which turn on if it has run. Plenty of hire and fleet contracts require the owner's approval for work.

Next: phone the hire company or your fleet manager first, then us — sorting it before our arrival is quicker. Stranded by Beacons Place Shopping Centre or outside the nearest station till the firm replies, the vehicle stays switched off throughout.

AdBlue in the diesel tank? Not sure, in Merthyr Tydfil

"I think so" is sometimes the most honest as it gets. Lighter, the bottle; a hint of ammonia round the filler; no clear memory of the cap. Sound familiar? The gates of the local primary school in a rush, perhaps, or someone's driveway out in Ynys-fach.

The point: the motor isn't harmed by a little AdBlue splashed around the filler. Once it is inside the diesel tank, though, it does. Any AdBlue in that tank will be sucked in by starting the car, and the start wouldn't settle which it is in any case.

Assume it went in, and never turn your key. Inspecting a tank that proves clean is better than emptying one once it's been run — so ring then tell us what you saw.

Merthyr Tydfil: what each AdBlue drain has in common

Each situation gets the same start to the job. Our engineers come to your car, whether it's on a forecourt, a driveway, the car park at The Belle Vue or a side street close to Saint David's Parish Church, and ask three things: what went in, about how much, and if the engine has run. Over the phone, ahead of anything else, you hear the price, and those answers decide the work too.

Draining the tank comes next, then a careful flush — more vital after urea than with petrol, since crystals and corrosion will not clear on their own, however long it sits. The filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Not started? Then roughly half an hour on site is most jobs.

We start the engine at the end. Our test that it runs smoothly on new diesel comes before our technicians go. If it's noticed soon, the vehicle very seldom has lasting damage, and the entire job takes place where it is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, so it's worth checking yours while we're on the way.
