AdBlue in a diesel motor: two tanks, two fillers

Not one liquid but two: that is how plenty of modern diesels near Barrows Green and Westwood carry, with diesel feeding your motor. AdBlue goes to the exhaust, where it is sprayed into the gas to fresh it, and it lives in a tank of its own.

Each tank has its own filler. Under one flap, next to each other: that's the arrangement on a lot of vehicles. Elsewhere, AdBlue's filler sits beneath the bonnet or in your boot instead. Diesel gets filled on every forecourt call-out, again and again. Seldom filled, AdBlue normally comes from a bottle, poured by a driver who must stop and think which cap to use. The mistake lives in that gap.

How AdBlue in your diesel tank occurs in Barrows Green

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

First, the warning. Low AdBlue brings a warning from the vehicle, and letting it run dry means limp mode — hence a rushed top-up, perhaps before work off Wagstaff Lane, perhaps outside Bull and Butcher on the way home after work.

Next, your hand reaches for the cap it would have used on the old vehicle — because a rental car, a new car or a company car puts the fillers where your last one did not.

A spouted bottle finds no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, after begun, keeps on. It takes seconds, be it out in Toadhole or bang in the centre of Barrows Green.

Telling the AdBlue filler from your diesel filler

A few seconds is all the checks take — so check them before you tip anything, on a drive in Pye Hill or a forecourt around Barrows Green.

  • The cap. The AdBlue cap is commonly blue, or marked "AdBlue". Your diesel cap normally is not. Read it instead of going by position.
  • Check the size: the smaller filler neck is, on many cars, the AdBlue one.
  • A label inside the fuel flap often says which fuel goes where, on plenty of cars. Check for it.
  • The handbook. If your filler isn't by your diesel cap, it's in the boot or under the bonnet, and the handbook says which.
  • Collecting a hire or company car, perhaps at the car park outside Alfreton? Ask whoever drove the car last before leaving, not once the light comes on.

Keeping AdBlue out of the diesel tank when you top up

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

  • Not in a rush on the side of Barrows Hill Lane, not on a slope, not with your motor running: park then switch off first.
  • Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it does the trick.
  • The diesel cap remains on. Where both share a flap, confirm it's shut before lifting the bottle.
  • Stop when the tank is topped up or the bottle is empty; until then, pour slowly through the own spout.
  • Only then, start the car: close the cap, check once more, and make sure your diesel cap was never opened.

Find at the second or third stage that AdBlue went into the wrong filler? That's where you stop. Never go on to stage five.

Barrows Green: already put AdBlue in the diesel tank?

What follows is a short order of things, starting with not starting your motor. On many diesels your ignition alone runs the fuel pump, and so do not switch it on. Do not top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is pulled from.

On a forecourt — BP, another forecourt nearby or another — the staff will usually help roll your car clear, when you ask. Leave it where it is if you're on your own driveway in Barrows Green.

Stop as soon as it is safe and switch off, if the engine has already run. The next junction means the place to leave when you're on the M1, under 3 miles from Barrows Green. A short hop across Barrows Green is a smaller job than a run towards Nottingham, under 15 miles away, so tell us roughly how far it went.

What occurs when our technicians turn up around Barrows Green

Anywhere the vehicle has stopped, whether by Westwood Infant and Nursery School, near St Helen's Church Selston or on your own drive, our van travels to it. The answers settle the work and the price, so we ask what was put in, roughly how much, and if it's run. The price comes over the phone, ahead of any van leaving.

The fuel system is then flushed thoroughly, once the tank is emptied. Much more than with petrol, it matters with AdBlue: the crystals build up, some metals are attacked, and nothing clears away on its own, however long it sits. The filter cleaned or, where needed, replaced; fresh diesel in; then a test of the car. Before leaving, our engineers fire it up and check that it is running properly.

Unstarted vehicles usually mean a half-hour job from arrival. The kit is fine on a live filling station, and hushed enough for a driveway after dark. Paying is on the day, not upfront, and you receive the paperwork an insurer wants: an engineer's report and a VAT invoice. Misfuelling cover is part of many insurance policies — and so use the wait to look at yours.
