AdBlue in a diesel vehicle: two tanks, two fillers

Not one liquid but two: that is what many newer diesels around Burntwood Pentre and Spon Green run, with diesel feeding your motor. Your exhaust, not the motor, is where AdBlue goes: dosed into the fumes to fresh them, from its own tank.

Different tanks, separate fillers. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. Filling the diesel side at the pump happens constantly. Much less commonly, the AdBlue side is topped up — mostly from a bottle, by a person thinking about where it goes. It is in the gap that the mistake happens.

How AdBlue in the diesel tank occurs around Burntwood Pentre

Seldom is it carelessness: usually three things line up.

On a drive off Standard Road before work, or in the car park outside The Burntwood on the way home: that is where the hurried top-up happens. Why the rush? As AdBlue gets low the car tells you, and once it's empty, limp mode kicks in.

Next, your hand reaches for the cap it would have used on the old motor — because a hire car, a new car or a company car puts the fillers where your last one didn't.

Third, the bottle goes in: diesel filler or AdBlue filler, it goes in as easily, and once the pour starts, nothing stops it. The same few seconds decide it, in the middle of Burntwood Pentre or out in Drury.

How to tell the AdBlue filler from the diesel one

Before you tip anything, whether on a drive in Buckley or a forecourt in Burntwood Pentre, check these. They take a couple of seconds.

  • Blue and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually does not. Trust the cap, not its position.
  • On plenty of vehicles, the size tells: AdBlue has the smaller filler neck.
  • The flap. Look inside your fuel flap for a label. Many motors say there which fuel goes where.
  • The handbook says which it lives when your filler isn't next to the diesel cap: your boot, or under the bonnet.
  • The person who drove it last. On a hire or company car collected from somewhere like the car park at Buckley, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

Anywhere across Flintshire the light comes on, this is a routine for the day.

  • Park and switch off. Not on a slope, not with the motor running, and not in a rush on the side of Mount Pleasant Road.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Daft, yes, yet it does the trick.
  • The diesel cap remains on. When the two sit under a flap, make sure it is closed before lifting the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty.
  • Shut the cap, then check once more — confirm your diesel cap stayed shut throughout. After that, start the car.

If at stage two or three you find you have already poured into the diesel side, stop there. Do not go on to stage five.

Put AdBlue in the diesel tank around Burntwood Pentre already?

Brief order, then. Top of it: your engine stays unstarted. Leave the ignition off too, since on many diesels it alone runs your fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of that tank, where the fuel is drawn from — so do not top up with diesel to thin it.

If you are at a forecourt, whether it's the Texaco or the BP, ask the staff to help push the vehicle away from the petrol pump. At home in Burntwood Pentre? So the vehicle remains put.

Stop as soon as it is safe then switch off, if your motor has already run. Burntwood Pentre sits under 10 miles from the M56; on it, take the next junction. Mileage counts — a short hop across Burntwood Pentre is a smaller job than heading under 10 miles to Chester — so say about how far it went.

When our engineers arrive around Burntwood Pentre, what occurs?

The van comes to the vehicle anywhere it stopped — your own driveway, near Globe Way Stadium, or by Dodleston CofE Primary School. Our technicians ask what went in, roughly how much, and if it's run, because those answers settle this work and our quote. The price is given over the phone, before any van leaves.

The fuel system is then purged thoroughly, after the tank is cleared. More than with petrol, it matters with AdBlue: crystals form, certain metals corrode, and none of that washes away on its own, however long it sits. Your filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before leaving, our engineers fire it up and check that it's running smoothly.

Unstarted vehicles mostly need a half-hour job from the moment we arrive. The equipment is fine on a busy filling station, and hushed enough for a driveway late at night. Paying happens on the day, not upfront, and you are given the paperwork your insurer wants: an engineer report and a VAT invoice. Wrong-fuel cover is included in many insurance policies — and so use the wait to look at yours.
