Denscombe: AdBlue in the Diesel Tank? Find Your Situation

Has your engine turned over since the AdBlue went in? This one question settles almost everything about what comes next. Not started so far? Then leave the vehicle like that, wherever your car sits — Denscombe or Bryngwyn. Keep nothing on, call 0333 366 0103, then count on a proper flush after a drain, done right where your car sits in Denscombe. Already run? Stop once safe, then turn everything off. A bigger job, then, but the same opening step.

Further down: the cases we meet, wherever around Caerphilly. Pick the one that fits.

At the pump around Denscombe: AdBlue in a diesel

Imagine it: stood by the petrol pump, holding the bottle, you spot the cap you took off was not the right one. Whether Texaco, Morrisons or somewhere else in Denscombe, the situation is identical.

Meaning? Spotting it on the forecourt is as good as it gets. The AdBlue is inside your tank and nowhere else. Nothing has pulled it in.

Clearing the petrol pump is no reason to start it — so don't get back in. Ring us from the forecourt once the car sits in a space — the staff will help roll it — and save the receipt. If it cannot be shifted, it can be drained at the petrol pump: the equipment is explosion-proof and safe on a busy forecourt.

AdBlue in the diesel tank at home in Denscombe

Several days had passed with the dash light on. Picked up a bottle, poured it in at home, recycled the empty — and only then looked at the cap again, after the fact. Just off Florence Grove is no different from any other place.

Meaning? Provided the car has not been driven since, it is close to the forecourt case. Diesel and AdBlue keep separate: the AdBlue drops to the base of the tank and stays put, however long the night.

What to do: leave your keys inside the house so no one moves the vehicle in the morning. Then call. Out in Caerphilly or here in Denscombe, the draining happens at your driveway. Even at night, the pumps stay quiet enough for a residential street.

AdBlue drain on a forecourt in Denscombe

On the road around Denscombe with AdBlue in a diesel

Rough running, smoke, lost power or a lit dashboard arrived a mile or two beyond the top-up. Maybe heading for Cardiff, under 10 miles away, or simply down Stockland Street.

The upshot: your system has drawn AdBlue through already. The high-pressure pump and each injector see it too on a bigger run, after the filter and pipework have had it. Each restart, like each mile, pushes it deeper.

Next: find a sensible spot, pull in, and switch your engine off. Services further on can wait: from the M4, under 3 miles out of Denscombe, use the next junction. Don't restart the car to see if it has cleared; it will not have. Roughly what distance did it gone? Tell us as you call.

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

You've had the vehicle hardly a week. Unbeknown to you, the AdBlue and diesel inlets are side by side here — unlike your own vehicle, which has none or stores it in another spot. It can happen to anyone, anywhere around Caerphilly.

In short: one extra step on top of the cases above, which depend on whether it's run. Work on the vehicle frequently needs the owner's go-ahead under rental or fleet agreements.

Settling it before the van turn up is quicker, so ring the rental company or your fleet manager, and then us. Stuck near Connect Life (Caerphilly Elim Church) or outside Caerphilly till someone answers, your car remains turned off the whole time.

Not sure it was AdBlue in your diesel tank, Denscombe?

"I think so" is often as honest as it gets. Lighter, the bottle; a trace of ammonia round your filler; a hazy memory of which cap. Sound familiar? The gates of the local primary school in a rush, perhaps, or a friend's drive out in Castle Park.

The upshot: the engine is not harmed by a little AdBlue spilled around the outside. A diesel tank with AdBlue inside is a different story. Starting your car cannot tell you which, and if there is AdBlue in your tank it will suck it in.

Take it that it got in, and don't start the engine. Tell us what you noticed on the phone. A clean tank checked is a better outcome than a run one drained.

The common ground in each Denscombe AdBlue drain

Whichever situation you are in, this job starts the same way. Wherever the car stands — Kings Arms's car park, a street beside Wesley Methodist Church, a driveway, a forecourt — the van arrives and asks for the liquid, the amount, plus whether the motor has been run. Answers set the work; the quote follows on the call whilst nobody has left yet.

Emptying that tank comes next, followed by a careful flush — more vital with urea than after petrol, since crystals and corrosion will not clear on their own, no matter how long you wait. Next is your filter — flushed, or swapped when necessary — followed by clean diesel, and a test of your vehicle. If your engine hasn't run, most jobs take about half an hour once we are there.

Firing it up comes last. Before we leave, it's tested to confirm it runs correctly on clean diesel. When it's noticed soon, the car very rarely has lasting damage, and the entire job takes place where it is. For your insurer: the engineer's report and the VAT invoice. For you: payment on the day, no money upfront. It is worth knowing: many insurers offer misfuelling cover, so a quick look at your policy as you wait pays.
