AdBlue in a diesel motor: two tanks, two fillers

Diesel feeds your engine — but many modern diesels driven around Wrea Green and Bryning hold a second fluid as well. Stored in a tank of its own, AdBlue is fed into the exhaust gas and cleans it.

Each tank has one filler of its own. Other cars keep the AdBlue filler in the boot or under the bonnet; plenty of others place the two together behind one flap. At the pump, the diesel side is topped up all the time. Rarely topped up, AdBlue normally comes out of a bottle, poured by someone who has to stop and think what filler it needs. The error lives in that gap.

Wrea Green: how AdBlue in your diesel tank takes place

Three things tend to come together, and carelessness is rarely one of them.

On a drive off Ribby Road before work, or in the car park at The Grapes on the way home: that is where the rushed top-up happens. Why the rush? As AdBlue runs low your car warns you, and if it is gone, limp mode follows.

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

No part stops the tip after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's a few seconds, whether out in Ribby or bang in the centre of Wrea Green.

Flushing a diesel fuel system after AdBlue, Wrea Green

Which filler is for AdBlue, and which for diesel?

Before you tip anything, whether on a drive in Little Plumpton or a forecourt in Wrea Green, check these. They take a couple of seconds.

  • Where it sits can mislead; the cap does not. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel ones usually do not.
  • Plenty of motors fit AdBlue the smaller neck of the two.
  • A label inside your fuel flap often says which fuel goes where, on many motors. Check for it.
  • In your boot or under the bonnet: that's where your filler is if it's not by your diesel cap, and the handbook tells you which.
  • Collecting a hire or company car, say at the car park at Moss Side? Ask the person who drove the vehicle last before leaving, not when the light comes on.

AdBlue top-ups that never reach your diesel tank

The day the light comes on, wherever in Lancashire, follow this routine.

  • Stop somewhere level, engine off, with time to spare — not rushing on the side of Fox Lane Ends.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Daft, perhaps, yet it does the trick.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on.
  • Gently does it, through the bottle's own spout, until it's full or the bottle runs out.
  • Before you start your car, shut the cap and check a second time that the diesel cap never opened off.

If at step two or three you find you have already poured into your diesel side, stop there. Step five stays out.

Wrea Green: already put AdBlue in the diesel tank?

Then the order of things is short. Do not start your engine. On many diesels the ignition alone runs the fuel pump, and so do not switch the car on. Filling up with diesel won't weaken it: rather than mixing, AdBlue sinks to the base of your tank, just where the fuel is taken from.

The attendants at EG On the Move, Shell or another forecourt will usually help pushing your car clear if asked. At home around Wrea Green? So the car stays where it is.

If the motor has already run, stop as soon as it is safe and switch off. The next exit is where to come off if you are on the M55, under 3 miles from Wrea Green. Mileage counts — a short hop across Wrea Green is a smaller job than heading under 10 miles towards Preston — so say about how far it went.

When our technicians turn up around Wrea Green, what happens?

Wherever the car has stopped, whether by Ribby with Wrea Endowed CofE Primary School, near Wrea Green Village Sign or on your own drive, our van comes to it. Both the work and our price rest on three answers — which liquid, which amount, and whether it's run — so our technicians ask. You get that quote on the phone, before anyone heads out.

The fuel system is then flushed thoroughly, after your tank is emptied. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Next our technicians start the car and confirm it runs correctly before we go.

Unrun cars usually mean a half-hour job from the moment we arrive. The equipment is fine on a busy filling station, and quiet enough for a driveway after dark. Nothing in advance; you settle up that day. At the end, a VAT invoice and the report from the engineer are handed to you for the insurer. Before we get there, take a look at your policy; plenty carry cover for misfuelling.
