Two fillers, two tanks: AdBlue in a diesel vehicle

Diesel feeds the engine — but plenty of current diesels seen around Kings Worthy and Easton carry another fluid too. Kept in a tank of its own, AdBlue is sprayed into your exhaust gas to clean it.

Different tanks, separate fillers. 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 fuelled at the pump all the time. Rarely filled, AdBlue normally comes from a bottle, tipped by a driver who has to stop and think what cap to use. The slip lives in that gap.

Kings Worthy: how AdBlue in your diesel tank occurs

Carelessness rarely explains it. What does is three things coming up at once.

On a driveway off Church Lane before work, or in the car park at Cart & Horses heading home: that is where the hurried top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle tells you, and once it's gone, limp mode follows.

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

Lastly, the spout fits: diesel filler or AdBlue filler, it slides in as readily, and after the tip begins, nothing halts it. Whether it happens in Abbots Worthy or the middle of Kings Worthy, it's the same few seconds.

Telling the AdBlue filler from your diesel filler

Look at these before pouring, on a forecourt around Kings Worthy or a drive out in Abbotts Barton. Seconds, no more.

  • Colour and marking: an AdBlue cap is often blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not where it sits.
  • The size. On many cars the AdBlue filler neck is the smaller of the two.
  • Look inside the fuel flap: plenty of motors carry a label there saying which fuel goes where.
  • In the boot or under the bonnet: that is where the filler is if it is not by the diesel cap, and the handbook tells you which.
  • Whoever had it before knows. Ask when you collect a rental or fleet car — at Winchester's car park, perhaps — not when the light comes on.

How to top up without AdBlue in the diesel tank

A routine for the day the light comes on, wherever in Hampshire that is.

  • Not in a rush on the side of London Road, not on a slope, not with your motor running: park then switch off properly.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Daft, yes, yet it works.
  • Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Stop once that tank is topped up or the bottle is empty; before that, pour slowly through its own spout.
  • Only after that, start the car: close the cap, check a second time, and make sure your diesel cap was never opened.

Spot at step two or three that it has already gone into your diesel side? So stop just there. Step five stays off limits.

AdBlue in your diesel tank already, around Kings Worthy?

Do not start your motor: that is where the short order of things begins. On many diesels your ignition alone runs the fuel pump, and so do not switch the vehicle on. Thinning it with more diesel fails, because AdBlue settles to the bottom instead of mixing — and that is where the fuel is sucked from.

Ask the staff to help roll the vehicle away from the pump if you are on a forecourt — the Shell, the Tesco or somewhere else. At home in Kings Worthy? So the vehicle remains put.

Stop as soon as it is safe then switch off, if your motor has already run. On the M3, under a mile from Kings Worthy, that means the next exit. Tell us about how far it went: a run towards Winchester, under 3 miles away, is a bigger job than a short hop across Kings Worthy.

What occurs when our technicians arrive in Kings Worthy

Our engineers come to your car wherever it has stopped, whether that's outside Kings Worthy Primary School, near Saint Mary or on your own drive. The replies settle this work and the quote, so our technicians ask what went in, about how much, and if it's run. On the call itself, you hear the price — ahead of anything else.

Next: draining, then a thorough flush of the entire system. Unlike petrol, AdBlue leaves crystals and attacks certain fuel-system metals, and none of that clears out unaided. Hence it counts more. The filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Before we leave, our technicians start the car and confirm that it is running properly.

With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which the motor hasn't run need about half an hour once our technicians arrive. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth checking your insurance as the van travels to you: misfuelling cover comes with plenty of policies.
