AdBlue in a diesel vehicle, and its separate tank

Diesel goes to the motor — but plenty of newer diesels seen about Calder Grove and Durkar carry a second liquid as well. AdBlue's own tank holds it, and from there it goes to the exhaust, where a spray treats the fumes.

Each tank has a filler of its own. Many of motors share a single flap for the two, whereas some put the AdBlue filler to the boot or under the bonnet. Diesel gets filled at every filling station call-out, week in, week out. Someone who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and much less commonly. That gap is where the mistake lives.

Calder Grove: how AdBlue in your diesel tank happens

Seldom is it carelessness: normally three things line up.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, your vehicle drops into limp mode. So the top-up is done in a hurry: on a drive off Denby Dale Road before work, or in the car park at The Navigation on the way home.

Then, the hand goes for the cap it knew on the old motor — since a hire car, a new car or a company car places the fillers where your last one didn't.

A spouted bottle finds no obstacle at a diesel filler any more than at an AdBlue one. So the pour, once started, carries on. Whether it takes place in Great Cliff or the middle of Calder Grove, it's the same few seconds.

How to tell the AdBlue filler from the diesel one

Whether a Calder Grove forecourt or a drive out in Addingford, take a few seconds over these before any goes in.

  • Position can mislead; the cap does not. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel caps usually do not.
  • On many vehicles, the size gives it away: AdBlue has the smaller filler neck.
  • A label inside the fuel flap frequently shows which fuel goes where, on plenty of cars. Check for it.
  • The handbook. If the filler isn't by the diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • The person who drove the car last. On a hire or company car collected from somewhere like the car park at Sandal & Agbrigg, ask before you leave, not when the light comes on.

Keeping AdBlue out of the diesel tank when you top up

Wherever in West Yorkshire the light comes on, here is a routine for that day.

  • Switch off once parked — flat ground, motor stopped, and never rushed by Winden Close on the verge.
  • Find the AdBlue filler, read the cap, and say the word "AdBlue" out loud as unscrewing it. It sounds daft. It works.
  • The diesel cap remains on. When both share a flap, make sure it's shut before lifting the bottle.
  • Stop when the tank is topped up or the bottle runs dry; until then, pour slowly using the own spout.
  • Close the cap, and check again — making sure your diesel filler stayed closed throughout. Only then, start the car.

Spot at step two or three that it has already gone into your diesel side? So stop just there. Don't carry on to step five.

Already put AdBlue in your diesel tank in Calder Grove?

Brief list, then. First: your engine stays off. Leave your ignition off too, since on many diesels it alone runs your fuel pump. Filling up with diesel will not thin it: rather than mixing, AdBlue sinks to the bottom of your tank, just where fuel is drawn from.

If you are at a forecourt, whether it is the BP or the Shell, ask the attendants to help roll your car away from the petrol pump. If you're on your own drive around Calder Grove, leave the vehicle where it stands.

When the engine has run already, pull over safely and turn the car off. On the M1, under a mile from Calder Grove, that means the next junction. Tell us roughly how far it went: a run towards Wakefield, under 5 miles away, is a bigger job than a short hop across Calder Grove.

When our technicians get there around Calder Grove, what occurs?

Our van reaches your car wherever it stopped — your own drive, beside Crigglestone Community Centre, or by Crigglestone Mackie Hill Junior and Infant School. What liquid was put in, the quantity, and if it ran: we ask because the answers set both work and price. No one sets off until you've had the quote by phone.

Then your tank is emptied and your system cleaned thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. A test is at the end: before that, clean diesel is added, and the filter is cleaned or changed as needed. Before we go, we fire it up and confirm that it's running smoothly.

With pumps fine on a busy forecourt and quiet enough to use outside a house at night, most jobs in which your motor hasn't run take about half an hour once our engineers arrive. Paying is on the day, not upfront, and you are given the documents an insurer wants: an engineer's report and a VAT invoice. Misfuelling cover is part of many insurance policies — and so use the wait to look at yours.
