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

Many modern diesels on the roads around Gringley on the Hill and Walkeringham carry two liquids, not one. Diesel goes to the motor. Its own tank keeps it, and from there it is sent to the exhaust, where spraying cleans the fumes.

Each tank comes with one 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 the boot or under the bonnet. The diesel side is filled at the pump all the time. Far less commonly, the AdBlue side is filled — mostly from a bottle, by a person thinking about where it goes. The mistake grows in the gap between them.

How does AdBlue in your diesel tank happen around Gringley on the Hill?

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

On a driveway off Horsewells Street before work, or in the car park at The Blue Bell heading home: that's where the rushed top-up takes place. Why the rush? As AdBlue runs low your car warns you, and once it is gone, limp mode follows.

Unfamiliar cars are next, as well. Hire cars, new cars and company motors put their fillers in new places, and the hand reaches for the cap it used on the old one.

A spouted bottle meets no obstacle at a diesel filler any more than at an AdBlue one. So the tip, after started, keeps on. The same few seconds settle it, in the middle of Gringley on the Hill or out in Wiseton.

Telling the AdBlue filler from your diesel filler

A few seconds is all these take — so run through them before you tip anything, on a drive in Beckingham or a forecourt around Gringley on the Hill.

  • Where it sits misleads; the cap doesn't. AdBlue ones tend to be blue or bear the word "AdBlue" — diesel caps normally do not.
  • The size. On many vehicles the AdBlue filler neck is the smaller of the two.
  • A label inside the fuel flap often shows which fuel goes where, on many motors. Look for it.
  • The handbook shows where it is if the filler is not next to your diesel cap: your boot, or under the bonnet.
  • Whoever had it before will know. Check as you pick up a hire car or company car — from Gainsborough Central's car park, perhaps — not once the light comes on.

AdBlue top-ups that never reach the diesel tank

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

  • Park then switch off. Not on a slope, not with your motor running, and not in a rush on the side of Little Lane.
  • Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Silly, yes, but it works.
  • The two under one flap? So confirm the lid on your diesel filler stays shut before lifting the bottle.
  • Tip slowly, using the bottle's own spout. Stop when it is full or when the bottle is empty.
  • Shut the cap, then look again — confirm your diesel filler stayed closed the whole time. Only then, start your car.

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

Already put AdBlue in the diesel tank around Gringley on the Hill?

Don't start your engine: that is where the short order of things starts. Keep the ignition off too, because on many diesels switching it on alone runs your fuel pump. Don't top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where the fuel is drawn from.

The staff at JET, Tesco or another forecourt will usually help to push the vehicle clear when you ask. Your own driveway in Gringley on the Hill is the place it should stay.

When the motor has been run already, stop safely then turn the vehicle off. The next exit is the place to leave when you are on the Doncaster By-Pass, under 10 miles from Gringley on the Hill. Tell us roughly how far it went: a run towards Doncaster, under 15 miles away, is a bigger job than a short hop across Gringley on the Hill.

What happens when our engineers turn up around Gringley on the Hill

Wherever the car came to rest, whether outside St Peter's CofE Primary and Nursery School, beside St Peter & St Paul's Church or at home, our van comes to it. The answers decide this work and the quote, so our technicians ask what went in, roughly how much, and if it has run. The price is given on the call, before any van leaves.

Draining the tank comes next, followed by a thorough flush of the fuel system. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. After your filter has been flushed — or renewed, where needed — fresh diesel goes in, and finally your vehicle is tested. We don't go until it has been started and is running properly.

Most jobs are done in about half an hour after our technicians arrive, provided the engine has not run — and the pumps our engineers use are fine on a live forecourt and quiet at night beside a house. No money in advance; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for the insurer. While we travel, take a look at your policy; plenty carry cover for misfuelling.
