AdBlue in the Diesel Tank in Robin Hood? Keep It Switched Off

AdBlue in your diesel tank? Then keep your engine off — and the ignition as well. AdBlue is urea mixed in water. As it is water-based, it will not ignite and never combines with diesel; damage only comes once your pump begins pulling it. Caught before the motor has been run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the vehicle is in Robin Hood. Phone 0333 366 0103 before you do anything else.

Robin Hood, AdBlue in the diesel tank: what to do at once

Do these:

  • So no one can switch the ignition on, pull the keys out.
  • Near moving traffic? So put your hazards on.
  • Which fluid, and roughly how much volume? Hang on to the bottle or your receipt, and our technicians will know.
  • Ring just where you are. Quote a WF3 3 postcode or the nearest street sign, and nobody has to search for you.

Things not to do:

  • Don't start the engine, even for a moment to move the car.
  • Your ignition remains off: on lots of diesels, switching it on is enough to run your fuel pump.
  • AdBlue does not mix in diesel — it separates out — so adding extra diesel won't weaken it.
  • Even a short way along Copley Lane is too far to drive the car.
  • Don't try to drain the vehicle yourself by the roadside.

Ask the attendants to help you move the car away from the pumps if you're at a forecourt around Robin Hood, whether it is the Robin Hood Service Station or elsewhere. Parked on your own drive? Then it stays just as it is.

AdBlue in a diesel tank, and what it does there

The engine isn't what AdBlue is made for; your exhaust is. Stored in a separate tank, it's injected into the exhaust stream to treat the gases. Nothing in it is supposed to pass through a fuel pump, and nothing in a fuel pump is built to handle it.

It does not blend. Once it is poured into the tank, AdBlue behaves nothing like fuel. Denser than diesel, it drops and collects underneath it — the very place the pickup draws from. A motor filled on a driveway in Lofthouse yesterday evening and left unstarted is the simple one. Nothing has pulled the AdBlue up so far — though once your engine runs, that's what is pulled first, directly from the bottom of that tank.

Two kinds of harm come from there. Crystals and corrosion. As the water evaporates, it strands urea that hardens in filters and tiny passages; meanwhile, because it eats at some metals, each part it touches suffers for as long as it remains in there. Overnight, a vehicle sitting around Robin Hood with AdBlue in its lines gets worse; where it's only in that tank, it doesn't. The water in it does damage of its own: your high-pressure pump and the injectors rely on diesel to lubricate them, and water gives them nothing.

Draining AdBlue from a diesel tank in Robin Hood

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

Petrol put into a diesel on Asda's forecourt makes your fuel watery — that's the main problem. No damage is done while it stays unused, blended into your diesel — only once your engine works on it.

The issue with AdBlue in a diesel is a totally wrong substance. Since it does not burn, running it through isn't an option. Nor can it be watered down, because it splits back out — and the next fill won't clear away crystals or corrosion. So the flush counts more with AdBlue, and turning the key "to see", in the heart of Robin Hood or out in Thorpe on the Hill, costs more than almost any other slip.

The good news is the same as with petrol. Anywhere in West Yorkshire the car has come to rest, an unstarted motor means the AdBlue still in the reservoir: the simplest part of any fuel system to empty.

How AdBlue ends up in a diesel tank in Robin Hood

Many vehicles put the AdBlue cap alongside the diesel one, occasionally behind one flap, and after dark the two may look identical. Nobody intends it. It mostly happens outside the house, from a bottle grabbed on the journey home, rather than at the forecourt.

It tends to happen 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 Robin Hood Primary School. A driver pours the bottle in at home, right off Sharp Lane, as the day ends. Or someone unfamiliar with that flap refills the vehicle in dim light, parked in the car park outside The Old Halfway House.

Rented cars, new cars, company motors, or the second car in a family with both fuels: the least familiar vehicles get it the most. Keep it off: that is the first response to the same mistake, anywhere in Robin Hood or the remainder of West Yorkshire you happen to be.

Robin Hood: started the motor with AdBlue in the diesel tank?

The AdBlue has left your tank, then. Via the filter, through the pipework, and — with any running time — on to the high-pressure pump and every injector: that is how far it has gone.

You may see the motor running unevenly, smoking, losing power, showing warning lights or cutting out, perhaps on the way back from Hopefield Park or halfway across Robin Hood. When you safely can, pull over and switch it off — with no turning it on again to test. Each start pulls more of it through.

Robin Hood sits under a mile from the M1; if you were on it, leave at the first junction and pull up somewhere safe rather than driving on.

A quick hop across Robin Hood to the car park by Robin Hood War Memorial is one matter; driving for Wakefield, under 5 miles away, is something else, because each mile pushes the AdBlue deeper in. So mileage matters. Roughly how far it had come is worth telling us.

Once the motor has run, the flush takes in more, and all of it is done where the vehicle has come to a stop. When it is noticed quickly, long-term damage is very unusual.

What draining AdBlue from a diesel involves in Robin Hood

The vehicle stays where it is, whether that's a street near Ramsgate Community Centre, a drive, a layby or a forecourt in Robin Hood, and the van travels to it. Before anything else our technicians ask what went in, roughly how much, and whether your motor has been run, because those replies determine the work.

Next, emptying your tank on the spot removes the polluted diesel and the AdBlue in one go. Your system is purged thoroughly, which matters more with AdBlue than with petrol, because what it leaves behind doesn't rinse out on its own. Clean diesel goes in once the fuel filter is flushed — or swapped, if it needs to be — and after that your car is tested. The majority of these jobs are a half-hour visit once our technicians arrive, provided the engine hasn't run. The pumps are explosion-proof, safe on a working forecourt and quiet enough to use outside a house at night.

Priming your system with clean diesel comes at the end. Starting the car comes next, and then you head off from where the car is parked, outside Outwood or on a drive around Robin Hood. Before we go, we confirm it is running smoothly with clean diesel in. Our technicians do it all wherever the car 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 want.

AdBlue drains around Robin Hood and across West Yorkshire

Carlton, Ouzlewell Green and Thorpe on The Hill are among the places around Robin Hood that the same teams reach, along with most of West Yorkshire beyond, throughout the WF postcode area. Phone and ask instead of guessing if you are close to a county line, or anywhere tricky to explain.

A mobile service suits Robin Hood, a village: there's no need to bring your vehicle to us, since our technicians empty it there, on a driveway, a side street, a car park or a filling station.

What AdBlue in a diesel tank costs to put right around Robin Hood

There's no fair single quote, because the jobs aren't the same. The cost changes first with how long, if at all, your engine has been running, and next with the amount of AdBlue that got in. After that it depends on where the car is and whether our van can get to it safely, which is simpler on an open drive than in a tight spot behind Middleton Library.

That's why every call from Robin Hood starts with the same three questions, asked before giving a figure, not after: what went in, how much, and if it's run. Those replies narrow the range right down to a single number.

Before anyone sets off, you hear our quote on the phone. And you pay on the day, card or by phone, with nothing upfront. Look at your policy while we are on the way: many include misfuelling cover.
