Two fillers, two tanks: AdBlue in a diesel car

Plenty of modern diesels in Houghton, as well as Kings Somborne, carry on two fluids; the engine takes only the diesel. Your exhaust, not the engine, is where AdBlue ends up: dosed into the fumes to clean them, from its own tank.

Different tanks, separate fillers. Other motors put the AdBlue filler in the boot or under the bonnet; plenty more place the two side by side under one flap. Diesel goes in on each forecourt call-out, week in, week out. Seldom topped up, AdBlue normally comes from a bottle, tipped by someone who must stop and think which cap it needs. The mistake lives in that gap.

AdBlue in your diesel tank in Kings Somborne: how it takes place

Carelessness seldom explains it. Instead is three things coming up at once.

To start with, the warning. Low AdBlue brings a message from your car, and letting it run out leads to limp mode — so a rushed top-up, perhaps before work off Church Road, perhaps at The Crown Inn on the way home after work.

Then the vehicle is strange. A hire car, a new motor or a company car puts the fillers where your last one did not, and your hand reaches for the cap it would have used on the old one.

A spouted bottle meets no resistance at a diesel filler no more than at an AdBlue one. And so the tip, after begun, carries on. Whether it occurs in Horsebridge or the middle of Kings Somborne, it is the same few seconds.

Flushing a diesel fuel system after AdBlue, Kings Somborne

Which filler is for AdBlue, and which for diesel?

Before you pour anything, whether on a drive in Ashley or a forecourt around Kings Somborne, check these. They take a couple of seconds.

  • Position misleads; the cap doesn't. AdBlue ones are often blue or carry the name "AdBlue" — diesel caps normally do not.
  • Look at the size: the smaller neck is, on many motors, the AdBlue one.
  • A label inside the fuel flap frequently says which fuel goes where, on plenty of vehicles. Look for it.
  • Cannot see it beside the diesel inlet? Then check beneath the bonnet or inside your boot — the owner's manual will say where.
  • Check with the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Mottisfont & Dunbridge.

Keeping AdBlue out of the diesel tank when you top up

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

  • Switch off once parked — level ground, motor stopped, and never rushed beside Old Palace Farm at the roadside.
  • Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — after you've located your filler and read it.
  • If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on.
  • Stop once your tank is topped up or the bottle runs dry; before that, pour gently using the built-in spout.
  • Shut the cap, then look once more — making sure your diesel cap stayed closed the whole time. After that, start your car.

Discover at the second or third stage that AdBlue went in the wrong filler? That's where you stop. Leave out step five altogether.

Already put AdBlue in the diesel tank in Kings Somborne?

Do not start the engine: that is how the short order of things starts. The fuel pump starts on many diesels the moment your ignition is switched on — and so leave it off. Topping up with diesel won't dilute it: instead, AdBlue drops to the bottom of your tank, just where the fuel is drawn from.

The attendants at the nearest petrol station, another forecourt nearby or any forecourt will normally help pushing the car clear if asked. Leave it where it is if you're on your own driveway in Kings Somborne.

Stop as soon as it is safe and switch off, if the motor has already run. On the M3, under 10 miles from Kings Somborne, that means the next junction. About how far did it go? Crossing Kings Somborne is smaller a job than a run of under 10 miles towards Winchester, and so tell us.

Kings Somborne: what takes place when we arrive

We come to the car wherever it has stopped, whether that's outside King's Somborne Church of England Primary School, near St. Peter & St. Paul or on your own drive. Both the work and our price rest on three replies — which liquid, what quantity, and if it's run — so we ask. That price is given over the phone, before any van leaves.

Next: a drain, then a full flush of the entire system. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. We do not leave until it has been fired up and is running smoothly.

If your motor has not run, most jobs take about half an hour once we're there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house after dark. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, have a look at your insurance documents; plenty carry cover for misfuelling.

The vehicle remains put. Our technicians drain it where it is — a side street close to John of Gaunt Palace Ruins, a lay-by on the way to Garlick Copse, a driveway. Guessing won't help behind Village Hall, close to a border, or anywhere awkward to describe; phone and ask.
