Black Horse Corner: AdBlue in the Diesel Tank? Leave It Off

Engine off, ignition off: that is how you start if AdBlue has gone into the diesel tank. Chemically, AdBlue is simply urea in water. It doesn't burn, it doesn't mix with diesel, and the damage it does begins when the fuel system draws it in. If your engine has not run yet, AdBlue in a diesel tank is normally drained and thoroughly rinsed where the vehicle stands in Black Horse Corner. Before you do anything else, phone 0333 366 0103.

AdBlue in the diesel tank around Black Horse Corner: the first few minutes

To do:

  • So no one can turn your ignition on, take your keys away.
  • If you are at all near moving traffic, put the hazards on.
  • Which product, and about what quantity? Hang on to the bottle or your receipt, and we can know.
  • Tell us a postcode starting CO7 9, or whichever street lies nearest, and our van finds you straight — so call wherever you stand.

Never:

  • Shifting your vehicle even a short way is no reason to start the engine.
  • Many diesels run their fuel pump the instant your ignition goes on, and so keep it off.
  • Adding extra diesel does not work: AdBlue settles out rather than thinning.
  • Don't drive it anywhere, not even a short way down Alresford Road.
  • Don't try to drain the vehicle yourself by the kerbside.

Ask the people behind the counter to help you roll your car away from the pumps if you are at a forecourt in Black Horse Corner, whether it is the Esso or somewhere else. At your own driveway, don't touch it at all.

AdBlue in a diesel tank, and what it does there

The engine is not what AdBlue is made for; your exhaust is. It goes into its own tank and is sprayed into your exhaust gas to fresh it. A fuel pump isn't made to take it, and AdBlue was never supposed to go through one.

Inside a diesel tank it behaves really differently from fuel. It doesn't mix in. Heavier than diesel, it sinks and collects below it — the very spot the pickup sucks from. When the system runs, the AdBlue is first to be pulled through. Until then it sits beneath your diesel, which is how a vehicle topped up in Rowhedge last night and never started stays the straightforward case, provided nobody turns the key.

Once it is drawn in, the harm comes in two forms. It attacks some metals used in fuel systems, attacking whatever it reaches till it's cleared from the system. And when the water goes, the urea turns into crystals that block filters and settle in narrow passages. If the AdBlue has reached the lines, waiting till morning around Black Horse Corner makes things worse. In your tank alone, waiting does nothing. Water lubricates nothing. The injection pump and every injector depend on diesel flowing past them, and so the water part harms them by itself.

Draining AdBlue from a diesel tank in Black Horse Corner

Why is AdBlue in a diesel often the bigger fault?

Petrol pumped into a diesel on Murco's forecourt leaves your fuel thin — that's the whole fault. It mixes with your diesel, and whilst it is in the tank it does no harm; the damage comes from running your engine on it.

AdBlue in a diesel is a problem of the wrong substance altogether. It does not burn, so it cannot just be run through. It does not stay mixed, and so it cannot be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That is 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 your car is in Alresford or the middle of Black Horse Corner.

As with petrol, there's good news. Anywhere around Essex your car has come to rest, an unrun motor means the AdBlue still inside the tank: the easiest bit of a fuel system to empty.

Black Horse Corner: how AdBlue ends up in a diesel tank

Nobody means to do it. The AdBlue filler on plenty of cars sits right next to the diesel filler, at times under the same flap, and the two caps can look alike in poor light. Usually it is not the forecourt: someone picks up a container driving home and tips it in outside the house.

A few familiar ways cover most cases. Halfway through the morning drop-off, the dashboard warns, and outside Millfields Primary School the refill is hurried. A driver pours the container in outside their house, right off Keelars Lane, as the day ends. Else, after dark outside Horse and Groom, your car gets refilled by a driver using that flap the first time.

It takes place most in the motors people know least: a hire car, a new motor, a company car, or the second vehicle of a household with one diesel and one petrol. Anywhere around Essex, Black Horse Corner as well, the slip doesn't change, and nor does the first step: keep it off.

AdBlue in your diesel tank around Black Horse Corner, and the motor started?

If so, the AdBlue is no longer inside your tank. Via the filter, along the lines, and — given any running — on to the injection pump and each injector: that is how far it travels.

You may see the engine running roughly, smoking, losing power, showing warning lights or cutting out, possibly on the way back from Gravel Pit Grove or halfway across Black Horse Corner. When safe, stop then switch everything off — with no turning it on again to see. Each start pulls more of it through.

On the M11, under 50 miles from Black Horse Corner, the next junction is where to leave, and anywhere safe is where to stop — not driving on.

A quick hop across Black Horse Corner to the car park by Wivenhoe Town Cricket Club is one matter; driving towards Colchester, under 5 miles away, is something else, since every mile pushes the AdBlue deeper in. So mileage matters. About how far it had come is worth telling us.

Once the engine has been started, the flush covers more, and all of it is done where the vehicle has ended up. Lasting damage is very rare when it is noticed soon.

Emptying AdBlue in a diesel in Black Horse Corner: what it takes

Wherever it has stopped around Black Horse Corner — a forecourt, a lay-by, a drive, a road beside Wivenhoe Methodist Church — the van comes to your car. Before anything else our engineers ask what went in, about how much, and whether the engine has run, since those answers settle this work.

Then your tank is drained where the car sits, and so the tainted fuel and the AdBlue come out together. With AdBlue, more so than with petrol, flushing counts: the fuel system is cleaned right through because residue will not wash away by itself. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Roughly half an hour once we arrive is usual for most jobs when your engine has not run. The pumps are explosion-proof, safe on a busy forecourt and quiet enough to use outside a house at night.

Lastly, the fuel system is primed with new diesel. Whether it's a parking space at Wivenhoe or a driveway around Black Horse Corner, that is where we fire it up and you set off. Our technicians check it runs properly on new diesel before we leave. The whole job is done where the vehicle is, so it never has to be taken to a garage. Insurers want a VAT invoice and an engineer report, and you get both at the end.

There's no honest single quote, because the jobs aren't the same. Whether the engine has run, and for how long, comes first in what moves the cost.
