Why does AdBlue in a diesel car need its own filler?

Plenty of modern diesels in Aldgate, like those in Easton on the Hill, carry on two fluids; your engine takes only the diesel. Its own tank keeps it, and from there it is sent to your exhaust, where a spray treats the gas.

Every tank comes with one filler of its own. Under one flap, side by side: that's the layout on a lot of cars. On others, AdBlue's filler is beneath the bonnet or in your boot instead. The diesel side is fuelled at the petrol pump all the time. Seldom filled, AdBlue normally comes out of a bottle, poured by someone who has to stop and think what cap it needs. It's in that gap that the slip lives.

AdBlue in the diesel tank around Easton on the Hill: how it takes place

It's hardly ever carelessness. Three things tend to line up.

On a drive off Church Street before work, or in the car park at The Blue Bell Pub heading home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low your car warns you, and if it's empty, limp mode kicks in.

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

Nothing halts the pour once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. The same few seconds settle it, in the middle of Easton on the Hill or out in Collyweston.

How to tell the AdBlue filler from the diesel one

Before you tip anything, whether on a driveway in Wothorpe or a forecourt in Easton on the Hill, check these. They take a few seconds.

  • The cap. The AdBlue cap is frequently blue, or marked "AdBlue". The diesel cap normally is not. Read it instead of going by position.
  • On many motors, the size tells: AdBlue gets the smaller filler neck.
  • A label inside the fuel flap frequently says which fuel goes where, on many vehicles. Check for it.
  • The handbook shows which it is when your filler is not next to the diesel cap: the boot, or under the bonnet.
  • Whoever had it before knows. Ask as you pick up a hire car or company car — from Stamford's car park, perhaps — not once the warning comes on.

AdBlue top-ups that never reach the diesel tank

On the day the warning comes on — anywhere you are across Northamptonshire — a routine to use.

  • Stop on level, engine off, with time to spare — never rushing on the side of New Road.
  • Silly as it sounds, saying "AdBlue" aloud while you unscrew the cap does the trick — after you've located the filler and read the cap.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave the car on.
  • Slowly does it, through the bottle's own spout, until it is full or the bottle runs out.
  • Only then, start the car: close the cap, check a second time, and make sure the diesel cap was never opened.

Discover at the second or third stage that the bottle went in the diesel filler? That's where you stop. Leave out stage five entirely.

AdBlue in the diesel tank already, in Easton on the Hill?

Brief order, then. Top of it: your engine remains off. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch it on. Filling up with diesel won't dilute it: instead, AdBlue sinks to the base of the tank, just where the fuel is taken from.

At a forecourt — BP, Morrisons or any other — the attendants will normally help roll your car clear, if you ask. If you are on your own driveway around Easton on the Hill, leave the car where it stands.

If your engine has already run, stop as soon as it is safe and switch off. On the Great North Road, under 10 miles from Easton on the Hill, that means the next junction. Distance counts — a quick hop across Easton on the Hill is a smaller job than heading under 15 miles towards Peterborough — so say about how far it went.

Our arrival in Easton on the Hill, and what happens next

We come to your car wherever it has stopped, whether that's outside Stamford St Gilberts Church of England Primary School, near Village Hall Easton-on-the-Hill or on your own drive. Both the work and our quote rest on three answers — what fluid, which amount, and whether it has run — so our engineers ask. You get that quote on the phone, before anyone sets off.

Then that tank is cleared and your system rinsed thoroughly. With AdBlue that matters 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 comes at the end: before that, clean diesel is added, and the fuel filter is cleaned or changed if necessary. Next we start the car and make sure it runs correctly before we leave.

Most jobs are done in roughly half an hour once our technicians get there, as long as your engine has not run — and the pumps we use are safe on a busy forecourt and quiet after dark outside a house. The insurer usually wants an engineer's report and your VAT invoice, and you get both once the job is done. Payment is on the day, with no deposit. Wrong-fuel cover is included in many insurance policies — so use the wait to look at yours.
