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

Diesel feeds the motor — but many newer diesels seen round Milehill and Grassmoor hold another fluid as well. Kept in a tank of its own, AdBlue is fed into the exhaust gas and cleans it.

There's a filler for each tank. Other motors keep the AdBlue filler in the boot or under the bonnet; a lot of others have the two side by side under one flap. The diesel side is fuelled at the pump all the time. Seldom filled, AdBlue usually goes in from a bottle, poured by a driver who must stop and think what cap to use. It is in that gap that the slip lives.

Milehill: how AdBlue in the diesel tank takes place

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

Hurry comes from the warning. Your car tells you as AdBlue runs low, and a dry tank puts it into limp mode — so the top-up gets done in a rush, before work on a drive off Mansfield Road, or on the way home in the car park at Three Cottages.

Next, your hand reaches for the cap it would have used on the old vehicle — because a hire car, a new motor or a company car places the fillers somewhere your last one didn't.

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 once it has started. Winsick or the middle of Milehill: it takes the same few seconds in both.

How to tell the AdBlue filler from the diesel one

Be it a Milehill forecourt or a driveway over in Temple Normanton, spend a couple of seconds on these before any goes in.

  • Colour and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not its position.
  • On many motors, size tells: AdBlue has the smaller filler neck.
  • Open the flap and check for a label — many cars mark what goes in which inlet just there.
  • The handbook shows where it lives when your filler is not next to the diesel cap: the boot, or under the bonnet.
  • Whoever had it before will know. Check as you pick up a rental or fleet car — from Chesterfield's car park, say — not once the light appears.

AdBlue top-ups that never reach the diesel tank

When the light comes on, wherever in Derbyshire, follow this routine.

  • Stop on level, engine off, with time in hand — not hurried on the side of Furnace Hillock Way.
  • Silly as it sounds, speaking "AdBlue" out loud while you unscrew the cap works — once you have found the filler and read the cap.
  • The two under a single flap? Then confirm the cap on the diesel filler is still closed ahead of 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 check once more — making sure the diesel cap remained shut throughout. After that, start the car.

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

Already put AdBlue in your diesel tank in Milehill?

Brief list, then. First: your motor remains off. Don't switch your ignition on; on many diesels that alone runs the fuel pump. Diluting it with extra diesel fails, because AdBlue settles to the base instead of blending — and that is where your fuel is pulled from.

If you are at a forecourt, whether it is the BP or the another forecourt nearby, ask the attendants to help push the car clear of the petrol pump. Leave it where it is if you're on your own drive around Milehill.

If the engine has already run, stop as soon as it is safe then switch off. Milehill sits under 3 miles from the M1; on it, take the first exit. Tell us about how far it went: a run towards Sheffield, under 15 miles away, is a bigger job than a short hop across Milehill.

Our arrival in Milehill, and what takes place next

Our van comes to the car anywhere it stopped — your own drive, beside St Pauls Church, or outside Hasland Junior School. Both the work and the quote rest on three answers — what liquid, what amount, and whether it has run — so our engineers ask. No one sets off until you've heard our quote by phone.

Then the tank is drained and the fuel system rinsed thoroughly. Unlike petrol, AdBlue leaves crystals and attacks some fuel-system metals, and none of it clears out by itself. Hence it matters more. The fuel filter is cleaned, or replaced where it needs to be; clean diesel goes in; and your car is tested. Before we leave, we fire it up and check that it's running smoothly.

Using pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs in which your motor hasn't run need about half an hour once we are there. Payment is on the day, not upfront, and you receive the documents an insurer asks for: an engineer report and a VAT invoice. It's worth looking at your insurance while we travel to you: misfuelling cover is included with many policies.
