AdBlue in a diesel vehicle: two tanks, two fillers

No single fluid but two: that's what plenty of modern diesels near Horsehay and Little Dawley run, with diesel for the engine. Its own tank keeps it, and from there it goes to your exhaust, where a spray treats the gas.

Each tank has its own filler. Some motors keep the AdBlue filler in the boot or under the bonnet; a lot of others have both side by side under one flap. The diesel side is topped up at the petrol pump all the time. The AdBlue side is topped up far less frequently, usually from a bottle, and usually by somebody who has to stop and think where it goes. The mistake grows in that gap between them.

How AdBlue in your diesel tank takes place in Horsehay

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

On a driveway off Woodlands Lane before work, or in the car park at Foresters Arms heading home: that's where the hurried top-up takes place. What is the reason for the rush? As AdBlue runs low the car tells you, and if it's gone, limp mode follows.

New-to-you vehicles come second, as well. Rentals, new cars and company cars place their fillers in new places, and the hand goes for the cap used on the old one.

Third, the spout fits: diesel filler or AdBlue one, it goes in just as easily, and once the pour begins, nothing halts it. Whether it happens in Coalmoor or the middle of Horsehay, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Horsehay

The AdBlue filler and the diesel filler: telling them apart

Before you pour anything, whether on a drive in Coalbrookdale or a forecourt around Horsehay, check these. They take a few seconds.

  • The cap. The AdBlue cap is often blue, or marked "AdBlue". The diesel cap normally is not. Read it rather than going by position.
  • Check the size: the smaller filler neck is, on many vehicles, the AdBlue one.
  • The flap. Look inside your fuel flap for a label. Many cars say there which fuel goes where.
  • The handbook says where it lives when your filler isn't next to your diesel cap: the boot, or under the bonnet.
  • Whoever had it before knows. Ask when you collect a rental or company car — from Telford Central's car park, say — not once the warning appears.

AdBlue top-ups that never reach your diesel tank

On the day the light comes on — anywhere you are in Shropshire — a simple routine to follow.

  • Pull in on level, motor off, with time in hand — not hurried on the side of Round House Park.
  • Find the AdBlue filler, check the cap, and say the word "AdBlue" aloud 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 — then leave the vehicle on.
  • Slowly is best, through the bottle's own spout, until it is full or the bottle is empty.
  • Close the cap and check once more. Make sure the diesel cap was never opened. Only then start your car.

Stop there if you find, at step two or three, that you have already poured into your diesel side. Don't go on to stage five.

AdBlue in the diesel tank already, in Horsehay?

Do not start your motor: that is where the short order of things begins. Keep your ignition off as well, because on plenty of diesels switching it on alone starts the fuel pump. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where the fuel is drawn from — so do not top up with diesel to dilute it.

If you are on a forecourt, whether it is the Esso or the Asda, ask the staff to help push your car clear of the petrol pump. If you are on your own drive around Horsehay, leave it where it stands.

Where the motor has been run by now, pull over safely and turn the vehicle off. The next junction is where to come off if you're on the M54, under 3 miles from Horsehay. Tell us roughly how far it went: a run towards Wolverhampton, under 25 miles away, is a bigger job than a short hop across Horsehay.

When our engineers get there around Horsehay, what occurs?

Our engineers come to the vehicle wherever it has stopped, whether that's outside Lightmoor Village Primary School, near Horsehay Methodist Church or on your own drive. The replies decide the work and our quote, and so our engineers ask what was put in, about how much, and if it has run. You get that price by phone, before anyone sets off.

Then that tank is drained and the 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. Testing is last: before that, clean diesel goes in, and the filter is flushed or changed as needed. Before we go, our technicians start the engine and check that it is running properly.

Using pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the motor hasn't run need about half an hour after we arrive. The insurer will ask for an engineer's report and the VAT invoice, and both are yours once the job is done. Payment is on the day, with no money upfront. Wrong-fuel cover is included in many insurance policies — and so make use of the wait to check yours.
