Two fillers, two tanks: AdBlue in a diesel motor

Many newer diesels on the roads about Wirksworth and Little Bolehill carry two liquids, not one. Diesel goes to your motor. Stored in a tank of its own, AdBlue is sprayed into the exhaust gas and cleans it.

Every tank comes with a filler of its own. On a lot of cars the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. The diesel side is topped up at the petrol pump all the time. 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.

Wirksworth: how AdBlue in the diesel tank takes place

Seldom is it carelessness: usually three things line up.

Haste comes from the warning. The car tells you as AdBlue runs low, and a dry tank sends it into limp mode — so the top-up happens in a rush, before work on a driveway off Dale End, or heading home in the car park at The Feather Star.

New-to-you motors come second, too. Rentals, new motors and company vehicles place their fillers differently, and the hand goes for the cap used on the old one.

And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the pour after it has started. It's seconds, whether out in Warmbrook or bang in the heart of Wirksworth.

Flushing a diesel fuel system after AdBlue, Wirksworth

The AdBlue filler and the diesel filler: telling them apart

Whether a Wirksworth forecourt or a driveway out in Bolehill, take a couple of seconds over these before any is poured in.

  • The cap. The AdBlue cap is regularly blue, or marked "AdBlue". Your diesel cap usually is not. Read it instead of going by position.
  • The size. On plenty of cars the AdBlue filler neck is the smaller of the two.
  • Open the filler flap and look for a label — many cars show which goes in which inlet right there.
  • Cannot see it next to the diesel filler? In that case look beneath the bonnet or in your boot — the handbook says where.
  • Check with the person who drove it last — before you leave, not when the light comes on — if you collect a hire or company car from somewhere like the car park outside Cromford.

AdBlue top-ups that never reach the diesel tank

A routine for the day the light comes on, wherever around Derbyshire that is.

  • Switch off once parked — flat ground, engine off, and never rushed beside St. Johns Street at the roadside.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it does the trick.
  • The diesel cap stays on. When the two share a flap, make sure it is closed before the bottle comes up.
  • Gently is best, through the bottle's own spout, until it's full or the bottle runs out.
  • Only after that, start the car: close the cap, check a second time, and make sure the diesel cap was never opened.

Stop there if you find, at step two or three, that you have already poured into your diesel side. Leave out stage five entirely.

Wirksworth: already put AdBlue in the diesel tank?

Do not start your motor: that's where the short order of things starts. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch the car on. AdBlue doesn't mix with diesel — it sinks to the bottom of your tank, where your fuel is pulled from — so do not top up with diesel to dilute it.

On a forecourt — The Co-operative, Murco or another — the staff will normally help push the car clear, when you ask. Leave it where it is if you're on your own drive around Wirksworth.

Where the motor has run by now, stop somewhere safe and turn the car off. On the M1, under 15 miles from Wirksworth, that means the next junction. Roughly how far did it go? Crossing Wirksworth is smaller work than a run of under 15 miles towards Derby, so tell us.

What occurs when our engineers turn up in Wirksworth

Our technicians come to the car wherever it has stopped, whether that's outside Wirksworth CofE Infant School, close to Wirksworth Library or on your own drive. What fluid went in, the amount, and if it ran: our technicians ask because those answers decide both work and quote. You hear that quote on the phone, before anybody sets off.

Then the tank is drained and the system rinsed thoroughly. Much more than with petrol, it counts here: the crystals form, some metals are attacked, and nothing washes away on its own, however long it is left. Testing is at the end: before that, fresh diesel is added, and your filter is flushed or changed if necessary. The motor is fired up next and checked to confirm it runs correctly, all before our engineers go.

Using pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs in which your motor has not run need roughly half an hour once our technicians arrive. No money in advance; you settle up on the day. At the end, a VAT invoice and a report from the engineer go to you for the insurer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours whilst we are on the way.
