AdBlue in the Diesel Tank in Lower Edmonton? Keep It Switched Off

If AdBlue has got into your diesel tank, keep your engine off then keep your ignition off. Urea mixed in water is all AdBlue is. Unlike fuel, it neither ignites nor blends, and nothing starts till the motor pulls it through. Caught before your engine has run, AdBlue in a diesel tank is usually a drain and a thorough flush, done where the car is around Lower Edmonton. Before you do anything else, phone 0333 366 0103.

AdBlue in your diesel tank in Lower Edmonton: the first few minutes

Things to do:

  • Pull the keys out, so nobody switches your ignition on.
  • If you're at all close to moving traffic, put the hazards on.
  • So you can tell us which fluid it was and about what quantity, keep the receipt or the empty bottle.
  • Our van finds you quickest with a postcode starting N9 7, or just the name of a street close by, so call from the car.

Do not do these:

  • No starting the engine — not for a second, not to reposition the vehicle.
  • Turning the key to ignition by itself starts the pump running on plenty of diesels. Skip it.
  • Do not top up with diesel to thin it. AdBlue doesn't dilute in diesel; it separates out.
  • Even a short distance along Millbrook Road is too far to drive the car.
  • Draining that tank yourself by the road is not worth trying.

On a forecourt in Lower Edmonton, whether it's the JET or another one, ask the attendants to help you push the vehicle away from the pump. Stopped on your own driveway? Then it remains just where it is.

What AdBlue does in a diesel tank

Not the motor but the exhaust is where AdBlue belongs. It goes into its own tank and is sprayed into the exhaust gas to fresh it. Not one side fits the other: urea doesn't belong in a pump, and a pump can't take urea.

Fuel mixes; AdBlue, once poured in, won't. The behaviour is nothing like diesel's. Heavier than diesel, it sinks and collects underneath it — the same place the intake sucks from. Simplest of all: a vehicle that got AdBlue in Southbury last night and has not been started since. The AdBlue sits at the base of that tank, untouched — but it would be first through if your engine starts, ahead of any diesel at all.

Two kinds of damage come from there. Crystals and corrosion. As the water dries, it leaves urea that hardens in filters and narrow channels; and, because it eats at certain metals, each part it reaches suffers for as long as it remains inside. If the AdBlue has reached the lines, leaving it overnight in Lower Edmonton leaves things worse. In the tank only, waiting does nothing. The water in it does damage of its own: the high-pressure pump and your injectors depend on diesel to lubricate them, and water gives them nothing.

Draining AdBlue from a diesel tank in Lower Edmonton

Why AdBlue in a diesel is often more serious than petrol

Petrol put into a diesel on Texaco's forecourt makes your fuel thin — that is the main issue. It mixes with the diesel, and whilst it is in your tank it causes no harm; the damage comes from running your engine on it.

With AdBlue in a diesel, the fluid as such is simply the wrong one. It can't simply be run through, since it doesn't burn. Nor can it be watered down, since it separates back out — and the following fill won't clear away crystals or corrosion. So the flush counts more with AdBlue, and trying your engine "to see", in the centre of Lower Edmonton or out in Ponders End, costs more than almost any other error.

The good news is the same as with petrol. If your motor hasn't run, the AdBlue is still in the tank, and that tank is the quickest part of a fuel system to clear, wherever across Greater London the vehicle is standing.

Lower Edmonton: how AdBlue ends up in a diesel tank

After dark, two caps side by side — the AdBlue one and the diesel one, now and then behind a single flap — may look the same. No one means it; many layouts allow it. It mostly takes place outside the house, from a bottle bought en route home, rather than at the filling station.

Mostly, it takes place in one of a few familiar ways. The refill is hurried outside St Edmund's Catholic Primary School, after the dash lit up with a warning as the kids were taken off. Near Findon Road, a driver pours a container in on the drive in the evening. Or the car is topped up in the car park outside The King William, in poor light, by a person who has never opened that flap before.

The least familiar vehicles get it the most — rentals, brand-new cars, company ones, and the spare car in a home with both fuels. Wherever you are in Lower Edmonton or the remainder of Greater London, it is the same mistake and the same first answer: leave it off.

AdBlue in your diesel tank in Lower Edmonton, and the motor started?

Then the tank is no longer where the AdBlue is. With any running, it travels to the injection pump and each injector, having passed via the filter and lines.

You may see the motor running roughly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Jubilee Park or halfway across Lower Edmonton. No restarting to test: pull over when safe, then turn everything off. With each start, more of it is pulled through.

Lower Edmonton lies under 5 miles from the M25; if you were on it, leave at the first junction and pull up safely instead of driving on.

A quick hop across Lower Edmonton to the car park by St Edmund's RC Church is one matter; driving towards London, under 10 miles away, is another, because each mile pushes the AdBlue further in. So mileage matters. Tell us roughly how far it had come.

Once your engine has been run, the flush includes more, and all of it is done where your car has come to a stop. Permanent damage is very unusual when it is noticed quickly.

What clearing AdBlue from a diesel involves in Lower Edmonton

A road by New River Church, a drive, a lay-by or a filling station: wherever the car has stopped around Lower Edmonton, our engineers come to it. Three answers decide the work, so first we ask which fluid was put in, roughly the amount, and whether your motor has run.

Then the tank is emptied where the car stands, so the contaminated fuel and the AdBlue come out together. What remains from AdBlue won't flush away by itself, so the fuel system gets a careful flush, which matters much more with urea than for petrol. Next, the fuel filter: flushed, or replaced if it has to be. After that clean diesel, and then a check of your vehicle. Not run? In that case expect about half an hour once we are there for most jobs. Low-noise enough to use outside a house at night, and fine on a working forecourt, the pumps are explosion-proof.

New diesel goes in to prime your system, and that's the final step. After that our engineers fire it up and you drive off, whether from a parking bay at Edmonton Green or a driveway in Lower Edmonton. Our technicians confirm it runs correctly on new diesel before we leave. The whole job is done where your car is, so it never has to go to a garage. You get a VAT invoice and an engineer report afterwards, which is what insurers ask for.

What AdBlue in a diesel tank costs to put right around Lower Edmonton

No single price could be fair, since each job differs. Three things change the cost: whether your engine has run and for how long, how much AdBlue got in, and where the vehicle is. That last one comes down to whether a van can reach it safely, and an open drive is simpler than a tight space behind Edmonton Baptist Church.
