AdBlue in a diesel motor, and its separate tank

Not one liquid but two: that's what plenty of modern diesels near Wapping and Barkerend carry, with diesel feeding your motor. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own.

Each tank has one filler of its own. Under one flap, side by side: that's the layout on many vehicles. Elsewhere, AdBlue's filler is beneath the bonnet or in your boot instead. The diesel side is fuelled at the pump all the time. A driver who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and much less commonly. Mistakes happen in the gap between them.

How AdBlue in the diesel tank happens in Wapping

It's rarely carelessness. Three things tend to line up.

On a drive off Bolton Road before work, or in the car park at The Corn Dolly on the way home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low the vehicle warns you, and if it is gone, limp mode follows.

The old car's cap is where your hand reaches — but a rental car, a new vehicle or a company car keeps the fillers somewhere else. That is the second thing: a new motor.

Third, the bottle fits: diesel filler or AdBlue one, it slides in just as easily, and after the pour begins, no part halts it. The same few seconds settle it, in the middle of Wapping or out in Eastbrook.

How to tell the AdBlue filler from the diesel one

Whether a Wapping forecourt or a driveway over in Low Fold, take a few seconds on these before any goes in.

  • Where it sits misleads; the cap does not. AdBlue ones are often blue or bear the word "AdBlue" — diesel caps normally don't.
  • On many motors, the size gives it away: AdBlue has the smaller filler neck.
  • Look inside the fuel flap: many cars have a label there saying which fuel goes where.
  • Cannot see it next to the diesel filler? In that case check below the bonnet or in the boot — the handbook says where.
  • The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Bradford Forster Square, ask before you leave, not when the light comes on.

Keeping AdBlue out of your diesel tank when you top up

When the light goes on, anywhere in West Yorkshire, use this routine.

  • Not in a rush on the side of Lingard Street, not on a slope, not with the motor running: park then switch off first.
  • Say "AdBlue" out loud as you unscrew the cap, after finding the AdBlue filler and read it. Daft, perhaps, yet it does the trick.
  • The two behind one flap? So confirm the cap on your diesel side is still closed ahead of lifting the bottle.
  • Stop once the tank is topped up or the bottle runs dry; before that, pour gently through its own spout.
  • Close the cap and check once more. Make sure your diesel cap was never opened. Only then start the car.

Find at step two or three that it's already gone into the diesel side? Then stop right there. Don't carry on to step five.

Already put AdBlue in your diesel tank in Wapping?

Then the order of things is short. Don't start your motor. The fuel pump starts on many diesels the moment your ignition is switched on — so keep it off. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where the fuel is sucked from — so don't top up with diesel to dilute it.

The attendants at Shell, BP or any forecourt will usually lend a hand to push the car clear if you ask. If you are on your own driveway in Wapping, leave the vehicle where it stands.

If your motor has already run, stop as soon as it is safe and switch off. The next junction is where to come off when you're on the M606, under 3 miles from Wapping. Tell us roughly how far it went: a run towards Bradford, under a mile away, is a bigger job than a short hop across Wapping.

When we arrive around Wapping, what happens?

Wherever your car has stopped, whether outside Westminster Church of England Primary Academy, beside LIFE Church UK or on your own drive, the van comes to it. Those answers settle the work and the price, so our engineers ask what was put in, roughly how much, and whether it has run. You get that price on the phone, before anybody sets off.

After that: draining, then a full flush of the whole system. Not like petrol, AdBlue forms crystals and eats at certain fuel-system metals, and none of it washes away unaided. Hence it matters more. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Before leaving, our engineers start the car and check that it's running smoothly.

Most jobs are finished in roughly half an hour once we get there, provided your engine hasn't run — and the pumps our technicians use are safe on a busy forecourt and quiet after dark outside a house. No money in advance; you settle up that day. Afterwards, the VAT invoice and a report from the engineer go to you for your insurer. Wrong-fuel cover is included in many insurance policies — so make use of the wait to check yours.

Shifting the vehicle isn't needed. Our technicians drain it where it is — a side street near Al‐Mahdi Mosque, a lay-by on the way to Norfolk Gardens, a driveway. If you're near a border, or somewhere hard to explain like the back of Al Abrar Academy Masjid, ring and ask instead of guessing.
