Lundwood: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has got into the diesel tank, keep your engine off and leave your ignition off. Urea mixed in water is all AdBlue is. The harm starts once it is pulled through the pump — it won't burn, and it will not blend with diesel. In Lundwood, AdBlue in a diesel tank found before your motor runs normally means a drain and a thorough flush, just where the vehicle is. Before you do anything else, ring 0333 366 0103.

AdBlue in your diesel tank around Lundwood: the first few minutes

Do these:

  • Keys out — that way nobody can switch anything on.
  • Near moving traffic? Then put the hazard lights on.
  • Which fluid, and about what quantity? Hang on to the bottle or the receipt, and our technicians will know.
  • Tell us a postcode starting S71 5, or whatever street lies closest, and the van finds you directly — so ring from wherever you are.

Don't do these:

  • Not even for a second, and not to shift the car: the motor remains off.
  • Turning the key to ignition by itself sets the pump running on plenty of diesels. Skip it.
  • AdBlue does not dilute in diesel — it separates out — so adding more fuel won't thin it.
  • Leave it where it is rather than driving it anywhere, even a short way down Littleworth Avenue.
  • Beside the road, don't try emptying it yourself.

Rolling the vehicle away from the island is a job for attendants to help with, whichever Lundwood forecourt you are on, the JET included. If you're on your own drive, leave the car precisely where it is.

What AdBlue does in a diesel tank

Not your engine but the exhaust is where AdBlue is meant to go. From a dedicated reservoir it is fed straight to the exhaust, cleaning what the motor emits. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

Fuel mixes; AdBlue, once tipped in, won't. Its behaviour is not at all like diesel's. The pickup sucks fuel from the deepest part of that tank, and that is exactly where AdBlue ends up: as it is denser than diesel, it sinks. The first thing the fuel system pulls through, after it runs, is the AdBlue. So a motor that had AdBlue poured in on a drive in Monk Bretton last night, and hasn't been started since, is still the straightforward case: the AdBlue is lying at the bottom of that tank, and nothing has pulled it in.

Once it's drawn in, the harm comes in two forms. It attacks some metals used in fuel systems, attacking whatever it touches until it is removed completely. And once the water evaporates, the urea turns into crystals that clog filters and lodge in tiny passages. A vehicle left standing around Lundwood with AdBlue already in its lines is worse by the morning; one with AdBlue just in its tank isn't. Water protects nothing. The high-pressure pump and each injector depend on diesel flowing through them, so the water part damages them by itself.

Draining AdBlue from a diesel tank in Lundwood

Petrol or AdBlue in a diesel: why AdBlue is often worse

Petrol pumped into a diesel on Tesco's forecourt makes the fuel watery — that's the main fault. Blended through the diesel and sitting unused, it's no threat at that stage; running your engine does the harm.

AdBlue in a diesel is a fault of the wrong substance altogether. It does not burn, and so it can't simply be run through. Nor can it be watered down, because it splits back out — and the next tankful won't clear away deposits or corrosion. So the flush matters more with AdBlue, and trying your engine "to see", in the centre of Lundwood or out in Stairfoot, costs more than nearly any other error.

The good news is the same as with petrol. If your motor has not run, the AdBlue is still in the tank, and the tank is the quickest part of a fuel system to clear, wherever in South Yorkshire the car is standing.

AdBlue in a diesel tank in Lundwood: how it ends up there

After dark, two caps together — the AdBlue cap and the diesel one, now and then under one flap — can look the same. No one intends it; plenty of designs allow it. Mostly it occurs with a bottle bought on the way home and poured in on the drive, not at the pump.

The ways it takes place are few and familiar. A warning light comes on during the school run, and the top-up happens in a hurry outside Outwood Primary Academy Littleworth Grange. A bottle is poured in at the end of the day on a drive just off Pontefract Road. Or the vehicle is topped up in the car park outside Lundwood Social Club, in poor light, by a person who has never opened that flap before.

It crops up most in a hire car, a brand-new car, a company vehicle, or the other car of a home with one of each fuels — the cars drivers use least. Wherever you are around Lundwood or the rest of South Yorkshire, it is the same mistake and the same first answer: leave the vehicle off.

Started your engine with AdBlue in the diesel tank around Lundwood?

Then the AdBlue has left that tank. It has been drawn through the filter and the fuel lines, and if your motor ran for any time, it has got to the high-pressure fuel pump and your injectors.

Rough running, smoke from the exhaust, lost power, dashboard warnings or cutting out: each might show up, perhaps midway across Lundwood or coming back from Littleworth Park. When you safely can, stop then switch everything off — with no turning it on again to test. Each start pulls more of that through.

Lundwood sits under 5 miles from the M1; if you were on it, exit by the next junction and stop somewhere safe instead of driving on.

Mileage counts: each mile pushes the AdBlue further in, and so heading for Wakefield, under 10 miles away, makes a far bigger job than crossing Lundwood to the car park by Burton Grange Community Centre. Approximately how far had it come? Tell us.

There's more to rinse out once your engine has been run, and we do all of it where the car has ended up. Noticed early, it very seldom leaves lasting damage.

Lundwood: how AdBlue is emptied from a diesel

Wherever it has come to rest in Lundwood — a forecourt, a lay-by, a drive, a road beside St Mary Magdalene's Church — our van travels to the vehicle. Before anything else our engineers ask what was put in, about how much, and if the motor has been run, since those answers determine the work.

Right there, the tank is then drained, and all of the contaminated diesel and the urea leave at once. The fuel system is cleaned thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. Next, your filter: cleaned, or changed when it must be. Then clean diesel, then a check of the vehicle. If the motor has not run, most jobs take about half an hour once we arrive. Quiet enough for use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.

The last step is to bleed the system on clean diesel. Whether it's a parking space by Barnsley or a driveway around Lundwood, that is where our technicians fire it up and you set off. The check before we go is that it runs properly on clean diesel. As the job is done in its entirety where your car is, a garage never comes into it. Your insurer will want an engineer's report and the VAT invoice — each handed over afterwards.

AdBlue drains in Lundwood and across South Yorkshire

Throughout the S postcode area, the teams taking AdBlue call-outs in Lundwood serve most of South Yorkshire too, Cundy Cross, Ardsley and Hoyle Mill included. Ring and check instead of guessing if you are by a county line, or anywhere tricky to pin down.

Wherever the vehicle sits — a driveway at home, a residential street, a car park, a filling station — our engineers drain it there, and there's no need to bring it to us; that suits Lundwood, a residential suburb, well.

What does AdBlue in a diesel tank cost to sort out in Lundwood?

Each job differs, so no fixed price is fair. Three things shift the cost: whether the motor has run and for how long, how much AdBlue got in, and where your car is. That last one rests on whether our van can reach it safely, and an open drive is easier than a tight gap behind Gatehouse.

Which fluid was put in, what quantity, plus whether the engine ran: every Lundwood call begins with precisely those, before a quote, not after. Once they are answered, a range turns into one fixed figure.

Quoted on the call before the van sets out, the job is paid for that day — card or phone, no deposit. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we are on the way.
