AdBlue in a diesel vehicle, and its separate tank

No single fluid but two: that is how plenty of modern diesels around Holywell Green and Little Bradley run, with diesel for your engine. AdBlue's own tank holds it, and from there it goes to the exhaust, and there a spray cleans the fumes.

Each tank has its own filler. Under one flap, next to each other: that's the layout on a lot of vehicles. Elsewhere, AdBlue's filler sits beneath the bonnet or in the boot instead. At the petrol pump, the diesel side gets filled constantly. The AdBlue side is fuelled far less commonly, normally from a bottle, and normally by somebody who has to stop and think where it goes. It's in the gap that the mistake lives.

Holywell Green: how AdBlue in your diesel tank takes place

Three things tend to line up, and carelessness is rarely one of them.

To start with, the warning. Low AdBlue brings a message from the car, and letting it run out means limp mode — so a rushed top-up, perhaps before work off Station Road, or at Duke of York on the way home that evening.

Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one did not, and the hand hits for the cap it would have used on the old one.

A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. So the pour, once started, keeps on. Whether it occurs in Northgate or the middle of Holywell Green, it is the same few seconds.

The AdBlue filler and your diesel filler: telling them apart

Look at these first, on a forecourt in Holywell Green or a drive out in Stainland. A few seconds, no more.

  • Position can mislead; the cap doesn't. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel caps normally don't.
  • The size. On many cars the AdBlue filler neck is the smaller of the two.
  • Look inside your fuel flap: plenty of motors have a label there showing which fuel goes where.
  • Can't find it beside your diesel inlet? Then look beneath the bonnet or in your boot — the handbook will say where.
  • Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park at Sowerby Bridge.

Topping up AdBlue without it reaching your diesel tank

A routine for the day the light comes on, wherever in West Yorkshire that is.

  • Switch off once parked — level ground, engine stopped, and not in a rush beside Shaw Lane on the verge.
  • Locate the AdBlue filler, read the cap, and say the word "AdBlue" out loud as you unscrew it. It sounds silly. It works.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the vehicle on.
  • Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
  • Before starting the vehicle, shut the cap and check again that your diesel cap never came off.

Discover during the second or third stage that the bottle went in the diesel tank? That is where you stop. Don't carry on to stage five.

Put AdBlue in the diesel tank in Holywell Green already?

Brief order, then. Top of that: the motor stays unstarted. The fuel pump runs on many diesels as soon as the ignition goes on — and so leave it off. AdBlue doesn't 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.

Ask the staff to help push your car away from the petrol pump if you are at a forecourt — the JET, the Scientific Lubricants or somewhere else. At home around Holywell Green? So your car remains where it is.

Stop as soon as it is safe then switch off, if the engine has already run. On the Outlane Interchange, under a mile from Holywell Green, that means the next junction. Mileage matters — a short hop across Holywell Green is a smaller job than driving under 10 miles to Bradford — so say roughly how far it went.

When our engineers arrive in Holywell Green, what occurs?

Wherever the car came to rest, be it outside Holywell Green Primary School, beside Stainland and Holywell Green United Reformed Church or on your own drive, our van comes to it. We ask what was put in, about how much, and whether it has run, since those answers settle the work and our price. Nobody sets off until you've heard the price over the phone.

Emptying that tank comes next, followed by a full flush of your system. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and neither washes away by itself. That is why it counts more. Testing is last: before that, fresh diesel is added, and the fuel filter is flushed or replaced as needed. We don't go until it has been fired up and is running properly.

With pumps fine on a working forecourt and quiet enough for use outside a house at night, most jobs in which your motor has not run take about half an hour after our technicians are there. Nothing upfront; you settle up that day. Afterwards, a VAT invoice and a report from the engineer are handed to you for your insurer. While we travel, take a look at your policy; plenty carry cover for misfuelling.
