Annbank: AdBlue in the Diesel Tank? Leave It Off

AdBlue in your diesel tank? Then leave your motor off — and the ignition too. Water with urea mixed in it: that is AdBlue. Not like fuel, it neither burns nor mixes, and no harm happens till your engine pulls it through. A drain and a thorough flush, done where the car is around Annbank, is normally what AdBlue in a diesel tank needs — if it is caught before the motor has been run. Phone 0333 366 0103 before you do anything else.

Those opening minutes: AdBlue in the diesel tank in Annbank

Do:

  • Remove the keys, which stops someone switching the power on.
  • Close to moving traffic? So put your hazards on.
  • The empty bottle or your receipt shows us the fluid and the quantity, and so do not throw it out.
  • Our van locates you quickest with a postcode starting KA6 5, or just the name of a street close by, and so call from the spot.

Not to do:

  • Not even briefly, and not to shift the vehicle: your engine remains off.
  • The ignition stays off: on many diesels, turning it on is enough to start the fuel pump.
  • Don't top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.
  • Even a short distance up Brown's Crescent is too far to drive it.
  • No emptying it yourself, either, on the roadside.

The attendants working at any Annbank forecourt — the Thames among them — will normally lend a hand rolling it aside if you ask. On that drive, the car stays exactly as it is.

AdBlue in a diesel tank, and what it does there

Not your engine but your exhaust is where AdBlue belongs. From a separate reservoir it goes straight to the exhaust, cleaning what your engine emits. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is made to handle it.

It doesn't blend. Once it's tipped into the tank, AdBlue acts not at all like fuel. It's heavier than diesel, and so it sinks and gathers at the bottom of the tank, which is where the pickup sucks fuel from. A car filled on a drive in Trabboch yesterday evening and left unstarted counts as the simple one. No pump has pulled the AdBlue up yet — though once the engine turns, that's what goes first, straight from the bottom of the tank.

Two kinds of harm come from there. Crystals and corrosion. As the water evaporates, it strands urea that hardens in filter elements and tiny passages; and, because it eats at certain metals, every part it reaches keeps suffering for as long as it remains in there. A car left standing in Annbank with AdBlue already in its lines is worse by the morning; one with AdBlue only in its tank is not. Diesel protects the high-pressure pump and each injector as it flows; water gives no lubrication, which is a second form of damage.

Draining AdBlue from a diesel tank in Annbank

Why is AdBlue in a diesel regularly the bigger issue?

Put petrol in a diesel at the Asda and you have a problem of thin fuel. Damage just comes from running on it. Blended into the diesel and left in that tank, it does nothing.

AdBlue in a diesel is a different problem: not thin fuel, but no fuel at all. Since it doesn't burn, running it through isn't an option. It does not stay mixed, and so it can't be weakened. And crystals and corrosion don't wash out with the next tank of fuel. That's why the flush counts more with AdBlue than with petrol, and why starting your motor "to see" costs more here than almost anywhere else, whether the vehicle is in Joppa or the middle of Annbank.

As with petrol, there's good news. If your engine hasn't run, the AdBlue is still inside the tank, and that tank is the simplest part of a fuel system to clear, wherever in South Ayrshire the car is sitting.

Annbank: how AdBlue ends up in a diesel tank

Nobody means to do it. The AdBlue filler on many motors sits right next to your diesel filler, at times under the same flap, and the two caps can look alike in poor light. It usually occurs at home, from a bottle bought en route home, rather than at the forecourt.

The ways it occurs are few and familiar. A warning light comes on during the school run, and the top-up occurs in a hurry outside the local primary school. Someone tips the container in at home, right off Weston Avenue, as the day ends. One more pattern: dim light, the car park outside the pub in the village, and a driver opening that flap for the first time.

It occurs most in the vehicles drivers know least: a hire car, a new vehicle, a company car, or the second vehicle of a household with one diesel and one petrol. Wherever in South Ayrshire, Annbank included, the mistake doesn't change, and neither does the first response: leave it switched off.

Already started the engine with AdBlue in the diesel tank in Annbank?

If so, the AdBlue is no longer in that tank. Given any running time, it goes on to the high-pressure pump and each injector, having passed through the fuel filter and pipework.

Watch for lumpy running, exhaust smoke, falling power, lights on your dash, or a stall — coming back from Brockle Wood, perhaps, or midway across Annbank. Pull over when it is safe. Turn off. Keep it off instead of restarting it to check. More of it is pulled through with each start.

Annbank lies under 15 miles from the M77; if you were on it, exit at the first junction and pull up safely instead of driving on.

Every mile pushes the AdBlue deeper into your system. That's why crossing Annbank to park beside James Brown Memorial and a drive of under 50 miles towards Glasgow are such distinct jobs. Let us know about how far it had come.

Wherever the car came to a halt is where all of it gets done, even with more to clean out once the motor has been running. Very rarely does it leave permanent damage if it's noticed early.

What draining AdBlue from a diesel involves in Annbank

The car remains where it is, whether that's a street near New Pebble Park, a driveway, a lay-by or a forecourt in Annbank, and our van travels to it. Three answers decide the work, and so first we ask which fluid was put in, about what quantity, plus whether your engine has run.

On the spot, the tank is then drained, and both the polluted diesel and the urea leave at once. A careful flush counts much more with AdBlue than after petrol, since residue will not wash away by itself. The filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Most of these jobs are a half-hour job once our engineers arrive, provided the engine hasn't run. Low-noise enough to use outside a house at night, and safe on a busy forecourt, the pumps are explosion-proof.

The last step is to bleed the fuel system on clean diesel. Firing it up comes next, and then you set off from where the vehicle is parked, outside Prestwick Town or on a drive around Annbank. Before we leave, we make sure it is running smoothly with fresh diesel in. The whole job is done where your car is, so it never needs to go to a workshop. You get a VAT invoice and an engineer report later, which is what insurers ask for.

About Annbank and where it is

Annbank is a small village situated on the banks of a river in South Ayrshire, with a relatively low elevation of 71 metres. Annbank lies near the villages of Mossblown, Sundrum, and Stair, and is approximately 28.9 miles from Glasgow. Annbank has a population of around 606 people, predominantly residing in flats. Annbank is located in a scenic area, with the city of Glasgow within commuting distance.

AdBlue drains across Annbank and South Ayrshire

Over the KA postcode area, the vans answering AdBlue call-outs around Annbank reach most of South Ayrshire as well, Mossblown, Sundrum and Stair among them. If you are close to a boundary, or somewhere hard to describe, ring and ask rather than guessing.

No moving is needed. In Annbank, a village, a van that comes to you works: your vehicle is drained on the spot, be it on a driveway, a side street, a car park or a filling station.

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

Each job differs, and so no single quote is fair. Three things change the cost: whether your engine has run and for how long, how much AdBlue was put in, and where your car is. That last one rests on whether our van can reach it safely, and an open driveway is easier than a tight gap behind Ayr Colliery No9 Pit.

That's why every call from Annbank starts with the same three questions, asked before giving a figure, not after: what got in, how much, and whether it has run. Given them, a range shrinks to a single firm number.

You get that quote on the phone, before anybody heads out, and you pay on the day, by card or by phone, with nothing upfront. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we are on the way.
