What Now? AdBlue in the Diesel Tank in Ty-Sign

What to do about AdBlue in a diesel tank comes down to one thing more than any other: if your engine has been run since it went in. Not started so far? Then keep the vehicle like that, whether the car sits — Ty-Sign or Danygraig. Usually that means draining and properly purging it right there around Ty-Sign — and so keep your ignition and engine off then call 0333 366 0103. Already run? Pull over once safe, then turn it off. A larger job, then, but the same first move.

AdBlue in a diesel on a Ty-Sign forecourt

Only now, bottle still in hand, you realise that the cap you opened was the wrong one, there at the pump. Be it Valero, Tesco or anywhere else in Ty-Sign, the case is the same.

In short: no better spot exists to discover it. The AdBlue is inside the tank and nowhere else. Nothing has pulled it in.

What to do: don't get back in and fire it up to clear the petrol pump. Ask the staff to help you roll the vehicle into a parking spot, keep the till receipt or the bottle, then ring us from the forecourt. Stuck beside the pump? Our explosion-proof equipment keeps a live forecourt sensible, so it can be drained in place.

AdBlue in your diesel tank at home in Ty-Sign

Days had passed with the dash light on. A bottle bought at the shop, emptied in on the driveway — and it's only at the bin that the cap caught your eye. Right off Eppynt Close is not less likely from anywhere.

The upshot: zero miles since makes this almost as good to finding it at the petrol pump. AdBlue does not mix with diesel; it sinks to the bottom of the tank and waits there. Overnight doesn't change that.

Next: prevent an early-morning move by keeping your keys in the house, then ring us. We drain it on your drive, whether that's around Ty-Sign or out in Pontymister. The pumps are quiet enough to use outside a house at night.

AdBlue drain on a forecourt in Ty-Sign

On the road in Ty-Sign with AdBlue in a diesel

Rough running, smoke, falling power or a glowing dashboard started a mile or two beyond the fill. Somewhere along Holly Road or else on the road to Newport — under 5 miles away.

In short: the AdBlue has been pulled through your fuel system. Distance decides how deep it goes: filter and lines to begin with, then the injection pump and each injector. Each mile and each restart takes it further.

Stop safely — that's the next step — then turn it off. Service stations further along are too far: from the M4, under 3 miles out of Ty-Sign, use the next junction. It won't have cleared, so there is no sense restarting to check. About how far did it gone? Tell us as you phone.

A hire or company car with AdBlue in the wrong tank?

Seven days ago, it was unknown to you. Unknown to you, the AdBlue and diesel fillers are side by side here — unlike your own car, which has no AdBlue or stores it elsewhere. Across Caerphilly, nobody is immune.

The point: exactly as above, split by if it ran, only with an added stage. Plenty of hire and fleet contracts require the owner's approval for work.

Sorting it before we arrives is quicker, so phone the hire company or your fleet manager, then us. If you're stranded in the car park at Risca & Pontymister, or by Ty Isaf Baptist Church, whilst you wait for an answer, leave the car off.

Unsure about AdBlue in the diesel tank in Ty-Sign?

"I think so" is sometimes the most honest answer there is. Too light, the bottle; a hint of ammonia near your filler; a hazy memory of which cap. Look familiar? The gates of the local primary school in a rush, perhaps, or a friend's drive over in Risca.

The upshot: your engine isn't harmed by some AdBlue splashed around the filler. A diesel tank with AdBlue inside is another matter. Any AdBlue in that tank will be sucked in by starting the vehicle, and the start would not settle which it is in any case.

Your move: behave as though it did, and don't start the engine. Describe what you saw on your phone. A clean tank checked is a happier outcome than a run one emptied.

The common ground in every Ty-Sign AdBlue drain

Whichever situation you are in, the job starts the same way. Forecourt, driveway, Masons Arms's car park or a road beside Risca Youth Centre — our van reaches your car, and three answers come next: which liquid, what quantity, and whether it ran. Answers set the work; the quote follows by phone while no one has set off yet.

Emptying the tank comes next, followed by a full flush — more vital with urea than after petrol, because crystals and corrosion won't go by themselves, however long you wait. Clean diesel is put in after your filter is cleaned or replaced, and the car is finally tested. If the motor hasn't run, the majority of jobs take about half an hour once we are there.

Lastly, our technicians start it. With new diesel in, it runs while we make sure it is running smoothly, and then we go. If it is spotted soon, the vehicle very seldom has permanent damage, and the entire job takes place where it is. Nothing is taken upfront, settlement is made on the day, and you receive what your insurer asks for: an engineer report plus a VAT invoice. Many policies include misfuelling, and so look at yours while the van travels.
