Warminster Common: AdBlue in the Diesel Tank? Leave It Off

If AdBlue has got into the diesel tank, keep your motor off then leave the ignition off. Urea mixed in water is all AdBlue is. The trouble starts once it is sucked through the lines — it will not burn, and it will not combine with diesel. Caught before your motor has run, AdBlue in a diesel tank is normally a drain and a thorough flush, done where the car is around Warminster Common. Phone 0333 366 0103 before you do anything else.

Warminster Common, AdBlue in the diesel tank: what to do right away

To do:

  • Pull your keys out, so no one switches your ignition on.
  • Hazards on, if moving traffic is anywhere near.
  • So you can tell us which liquid it was and about how much, keep your receipt or the empty bottle.
  • Call us from where you are. A postcode starting BA12 8, or the name of the nearest street, brings the van to you without a search.

Things not to do:

  • Don't start the engine, even for a moment to shift your car.
  • Don't switch the ignition on. On plenty of diesels that alone runs the fuel pump.
  • Adding more diesel doesn't work: AdBlue settles out rather than blending.
  • Do not drive the vehicle anywhere, not even a short way along Alcock Crest.
  • Draining that tank yourself beside the road is not one to try.

The staff on duty at any Warminster Common filling station — the Morrisons among them — will usually lend a hand pushing it aside if you ask. At home, the vehicle remains just as it is.

What AdBlue does in a diesel tank

AdBlue is made for your exhaust, not the motor. From a separate tank it goes directly to the exhaust, treating what the engine lets out. A fuel pump isn't made to take it, and AdBlue was never intended to go through one.

Poured in with your diesel, it keeps separate instead of blending — entirely unlike fuel. It sinks, since it's denser than diesel, and settles low where the intake draws its supply from. A car filled on a drive in Sutton End yesterday evening and not started since counts as the simple case. No pump has sucked the AdBlue up yet — but once the engine runs, that is what is pulled first, directly from the bottom of the tank.

From there it causes two kinds of harm. Crystals and corrosion. As the water dries, it leaves urea that crystallises in filters and tiny channels; and, since it attacks some metals, each part it reaches suffers for as long as it stays in there. Where the AdBlue has reached the pipework, leaving it till morning around Warminster Common makes it worse. In the tank only, time costs nothing. The water in it does harm of its own: the high-pressure fuel pump and the injectors rely on diesel to lubricate them, and water offers them nothing.

AdBlue in a diesel: why it is often worse than petrol

Petrol pumped into a diesel on Esso's forecourt leaves your fuel watery — that is the whole issue. Damage only comes from running on it. Blended into the diesel and left inside your tank, it causes nothing.

With AdBlue in a diesel, the liquid as such is plainly the wrong one. It cannot just be run through, since it does not burn. It doesn't stay mixed, so it can't be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters 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 Henfords Marsh or the middle of Warminster Common.

The same good news holds as with petrol. Wherever across Wiltshire the car has stopped, an unstarted motor means the AdBlue yet inside the tank: the simplest bit of a fuel system to empty.

How does AdBlue end up in a diesel tank around Warminster Common?

It's not on purpose. Many cars have the AdBlue cap beside the diesel one, now and then behind a single flap, and mixing them up is simple in poor light. It mostly occurs at home, from a bottle bought on the journey home, not at the forecourt.

It tends to take place in a couple of familiar ways. A warning light comes on during the school run, and the top-up takes place in a hurry outside Princecroft Primary School. In the evening, a container goes in on a driveway near Brook Street. Or your car is topped up in the car park outside The Bell & Crown, in poor light, by someone who has never opened that flap before.

It takes place most in the cars motorists know least: a hire car, a new car, a company car, or the second vehicle of a household with one diesel and one petrol. An identical mistake, an identical first step — leave it off — anywhere you happen to be in Warminster Common or the rest of Wiltshire.

AdBlue in the diesel tank around Warminster Common, and the motor started?

Then that tank is no longer where the AdBlue is. Given any running, it goes on to the high-pressure pump and each injector, after passing through the fuel filter and lines.

Perhaps coming back from the green space at the edge of the village, or midway across Warminster Common, the engine might go lumpy, smoke, lose pace, light up the dash or stall. Stop when it is safe. Switch off. Leave the vehicle off rather than restarting it to check. Each start pulls more of that through.

If you were on the M4, under 25 miles from Warminster Common, come off at the next exit and stop somewhere sensible instead of pressing on.

Distance counts: every mile pushes the AdBlue deeper in, and so heading for Bath, under 15 miles away, makes a far bigger job than hopping across Warminster Common to the car park by Christ Church. Roughly how far had it come? Tell us.

Our technicians do all of the rinsing where your car has come to a stop, and once your engine has run there is more of it. Very seldom does it leave permanent damage when it is noticed early.

Warminster Common: how AdBlue is emptied from a diesel

The vehicle stays put, whether that's a street beside The Obelisk, a driveway, a layby or a forecourt around Warminster Common, and the van comes to it. Three replies shape the job, so first our technicians ask what was put in, roughly the amount, plus whether your motor has run.

Next, draining your tank on the spot removes the contaminated diesel and the AdBlue together. With AdBlue, more so than with petrol, flushing matters: the whole system is cleaned all the way through since what remains will not flush out by itself. Testing your vehicle comes at the end, after fresh diesel is added and the filter is cleaned or, if needed, swapped. The majority of these jobs are a half-hour job once our engineers get there, provided the motor hasn't run. Our equipment is explosion-proof, and so a busy forecourt is no issue, and it's quiet enough for a residential street after dark.

Fresh diesel goes in to bleed the fuel system, and that is the last step. Whether it's a parking bay outside Warminster or a drive in Warminster Common, that is where we fire it up and you set off. Before we leave, our technicians confirm it is running correctly with fresh diesel in. Our engineers do it all wherever the vehicle has ended up, and it never has to be taken to a garage. You receive a VAT invoice and an engineer report later on, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right around Warminster Common

Not one flat figure could be fair, because every job differs. The price moves first with how long, if at all, the engine has been running, and next with the quantity of AdBlue that went in. After that it turns on where the car is and whether a van can get to it safely, which is simpler on an open drive than in a tight gap behind The Library.

Before a figure, never after, each enquiry from Warminster Common opens with the same three checks: the fuel, the quantity, plus whether the engine ran. The answers turn a range into a straight quote.

The price is quoted during the call, before anyone leaves; payment happens on the day, by card or over the phone, with nothing upfront. Misfuelling cover comes with many insurance policies, so it is worth looking at yours before the van gets there.
