Barry Dock: AdBlue in the Diesel Tank? Leave It Off

With AdBlue in the diesel tank, the ignition remains off and so does the engine. In plain terms, AdBlue is simply urea in water. The trouble starts once it's pulled through your lines — it won't burn, and it won't combine with diesel. A drain and a thorough flush, done where the car is around Barry Dock, is usually all AdBlue in a diesel tank needs — if it is caught before the engine has been run. First, ring us on 0333 366 0103.

Those opening minutes: AdBlue in your diesel tank in Barry Dock

Do:

  • Pocket the keys, and that prevents someone turning the power on.
  • Hazards on, if moving traffic is at all near.
  • The empty bottle or your receipt tells us the fluid and the amount, and so do not throw it out.
  • Call us from where you are. A postcode starting CF63 4, or the name of the nearest street, gets the van to you without a search.

Things not to do:

  • Do not start the motor, even for a moment to shift your car.
  • Don't switch the ignition on. On plenty of diesels that alone runs the fuel pump.
  • Do not top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.
  • Any driving at all is best avoided, even a short distance down Merthyr Street.
  • Beside the road, do not attempt draining it on your own.

On a forecourt around Barry Dock, whether it is the Morrisons or another one, ask the staff to help you roll the vehicle clear of the petrol pump. At your own driveway, do not move it at all.

AdBlue in a diesel tank: what it does

The motor isn't what AdBlue is made for; your exhaust is. It goes into its own tank and is sprayed into the exhaust gas to clean it. No part inside an injection pump is designed for this liquid — and none of it was meant to go that way.

Fuel mixes; AdBlue, once poured in, will not. The behaviour is not at all like diesel's. The intake takes fuel from the deepest part of the tank, and that is precisely where AdBlue ends up: as it is denser than diesel, it sinks. The first thing your fuel system pulls through, after it runs, is the AdBlue. So a car that had AdBlue poured in on a drive in Gibbonsdown last night, and has not been started since, is still the easy case: the AdBlue is lying at the bottom of the tank, and nothing has drawn it in.

After it is pulled in, the harm takes two forms. What is left once the water evaporates is urea, which forms crystals: they settle in tiny channels and clog filters. Worse, it eats at certain metals in a fuel system, and keeps going till it's flushed out. Overnight, a car sitting in Barry Dock with AdBlue in its lines grows worse; where it's only inside your tank, nothing changes. The water in it does harm of its own: the high-pressure fuel pump and your injectors rely on diesel to lubricate them, and water offers them nothing.

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

Fill a diesel with petrol by mistake at the Asda, and the issue is thinned fuel. No harm comes as long as it sits put, mixed into your diesel — only once the engine works on it.

With AdBlue in a diesel, the liquid as such is simply the wrong one. It does not burn, and so it cannot simply be run through. Whether your car sits in Merthyr Dyfan or the centre of Barry Dock, turning it over "to see" costs more with AdBlue than almost any other error, and the flush matters more. Why: it won't remain mixed, and so diluting it fails; and deposits and corrosion survive the following fill.

As with petrol, there's good news. Wherever around The Vale of Glamorgan your vehicle has come to rest, an unrun engine leaves the AdBlue still inside the reservoir: the easiest part of any fuel system to empty.

How does AdBlue end up in a diesel tank in Barry Dock?

Plenty of vehicles place the AdBlue filler beside the diesel one, now and then behind a single flap, and after dark the two can appear identical. No one intends it. It mostly takes place outside the house, from a bottle grabbed on the journey home, rather than at the forecourt.

The ways it occurs are few and familiar. Midway through the drop-off, the dashboard flags it up, and outside the local primary school the top-up is hurried. Near Greenwood Street, a driver tips a container in at home in the evening. Else, in dim light outside The Butterfly Collector, the vehicle gets refilled by a driver opening that flap for the first time.

The least familiar cars get it most — rentals, brand-new cars, fleet cars, and the other motor in a family with one of each fuel types. Wherever around The Vale of Glamorgan, Barry Dock included, the mistake does not change, and nor does the first response: leave it off.

Barry Dock: started your engine with AdBlue in the diesel tank?

In that case, the AdBlue is no longer in your tank. With any running, it travels to the high-pressure pump and every injector, after passing via the filter and lines.

Lumpy running, smoke from the exhaust, lost power, dashboard warnings or stalling: any may show up, maybe midway across Barry Dock or returning from Belvedere Crescent Park. Pull over when safe. Switch off. Keep it off instead of restarting it to check. Every start pulls more of it through.

If you were on the M4, under 10 miles from Barry Dock, come off at the next junction and stop somewhere sensible instead of pressing on.

Every mile carries the AdBlue deeper in. That's why a hop across Barry Dock to park near Salem Baptist Church and a drive of under 10 miles for Cardiff are such separate jobs. Tell us about how far it had come.

Wherever your car came to a stop is where all of it gets done, even with more to clean out after your engine has been running. Very rarely does it leave lasting damage if it's caught early.

Barry Dock: how AdBlue is emptied from a diesel

The car remains put, whether that is a street near Pioneer Hall, a drive, a layby or a forecourt in Barry Dock, and our van comes to it. What got in, about the quantity, plus if your engine has been run: we check first, since those decide the work.

On the spot, the tank is then drained, and both the polluted diesel and the urea come out at once. The fuel system is cleaned thoroughly, which counts more with AdBlue than with petrol, since what it leaves behind doesn't rinse out on its own. Fresh diesel goes in once your filter is flushed — or replaced, if it needs to be — and after that your car is tested. Most of these jobs are a half-hour visit once our technicians get there, provided your engine has not run. Our pumping gear is explosion-proof, so a busy filling station is no problem, and it is hushed enough for a residential street late at night.

The last step is to bleed the fuel system on fresh diesel. Firing it up comes next, and then you drive off from where the car is parked, by Barry Docks or on a driveway in Barry Dock. It's tested on new diesel to make sure it runs properly before our technicians leave. The entire job is done where the car is, so it never needs to be taken to a workshop. At the end, you are given paperwork for your insurer: a VAT invoice plus a written report from the engineer.

What AdBlue in a diesel tank costs to put right around Barry Dock

Every job is different, so no single quote would be fair. The price changes first with how long, if at all, your engine has been running, and next with the quantity of AdBlue that went in. After that it turns on where the vehicle is and whether a van can reach it safely, which is easier on an open driveway than in a tight space behind Castleand Community Centre.

That's why each call from Barry Dock starts with the same three questions, asked before giving a figure, not after: what was put in, how much, and whether it has run. The answers turn a range into a straight price.

Our quote is quoted during the call, before anyone leaves; payment comes on the day, by card or over the phone, and nothing upfront. While our engineer is travelling, check your policy: plenty cover misfuelling.
