AdBlue in a diesel motor: two tanks, two fillers

Diesel goes to your motor — but many newer diesels seen about Witton and Primsland carry a second liquid as well. AdBlue's own tank keeps it, and from there it is sent to the exhaust, and there spraying treats the gas.

Separate tanks, separate fillers. Plenty of motors share a single flap for the two, whereas some move the AdBlue filler to your boot or under the bonnet. The diesel side is fuelled at the pump all the time. A driver who has to stop and work out where it goes usually tops up the AdBlue side, from a bottle, and far less commonly. That gap is where the slip lives.

How does AdBlue in your diesel tank occur in Witton?

Rarely is it carelessness: usually three things line up.

On a driveway off Evertons Close before work, or in the car park at The Red Lion heading home: that's where the rushed top-up happens. Why the rush? As AdBlue gets low the car tells you, and once it's empty, limp mode kicks in.

The old car's filler is where the hand reaches — but a hire car, a new motor or a company car keeps the fillers somewhere else. That is the second thing: a strange vehicle.

Lastly, the spout goes in: a diesel filler or AdBlue one, it goes in just as readily, and after the tip starts, nothing stops it. The same few seconds decide it, in the middle of Witton or out in Copcut.

Telling the AdBlue filler from your diesel filler

Before you tip anything, whether on a drive in Newtown or a forecourt in Witton, check these. They take a couple of seconds.

  • Position misleads; the cap does not. AdBlue ones are often blue or carry the name "AdBlue" — diesel ones usually do not.
  • The size. On many motors the AdBlue filler neck is the smaller of the two.
  • A label inside your fuel flap often shows which fuel goes where, on many vehicles. Look for it.
  • The handbook says where it lives if the filler is not next to your diesel cap: your boot, or under the bonnet.
  • Check with the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park at Droitwich Spa.

How to top up without AdBlue in your diesel tank

For the day the warning appears — anywhere you are in Worcestershire — a simple routine to follow.

  • Not in a rush on the side of Lawley Way, not on a slope, not with the engine running: park then switch off properly.
  • Locate the AdBlue filler, check the cap, and say the name "AdBlue" out loud while unscrewing it. It seems silly. It does the trick.
  • The two behind a single flap? So make sure the lid on the diesel side stays shut before lifting the bottle.
  • Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty.
  • Close the cap and check once more. Make sure your diesel cap was never opened. Only then start your car.

Spot at step two or three that it has already gone into your diesel side? So stop just there. Leave out stage five altogether.

Put AdBlue in your diesel tank in Witton already?

What follows is a short order of things, starting with no starting your engine. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch it on. Topping up with diesel won't thin it: instead, AdBlue sinks to the bottom of that tank, right where the fuel is drawn from.

Ask the attendants to help roll the vehicle clear of the petrol pump if you're at a forecourt — the BP, the Sainsbury's or somewhere else. At home in Witton? Then your car remains where it is.

If the motor has already run, stop as soon as it is safe then switch off. The next junction means where to come off if you are on the M5, under a mile from Witton. Distance counts — a short hop across Witton is a smaller job than driving under 10 miles towards Worcester — so say roughly how far it went.

What happens when we arrive in Witton

We come to the vehicle wherever it has stopped, whether that's outside Chawson First School, near The Church of the Sacred Heart and Saint Catherine of Alexandria or on your own driveway. Those replies decide the work and the price, and so our technicians ask what went in, about how much, and whether it has run. During the phone call itself, you are told the quote — before anything else.

The system is then flushed thoroughly, after the tank is cleared. Not like petrol, AdBlue forms crystals and eats at some fuel-system metals, and none of that washes away by itself. That is why it matters more. Your filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and your car is tested. Next our engineers fire it up and make sure it runs properly before we leave.

With pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs in which your engine has not run take about half an hour after our engineers are there. Nothing in advance; you settle up on the day. Afterwards, the VAT invoice and the report from the engineer go to you for your insurer. Before we get there, have a look at your insurance documents; plenty carry cover for misfuelling.
