AdBlue in a diesel car: two tanks, two fillers

Plenty of modern diesels in Hamworthy, as well as Ham Hill, run on two fluids; the engine takes just the diesel. Its own tank keeps it, and from there it is sent to your exhaust, where a spray treats the gas.

There is a filler on each tank. Plenty of motors share a single flap for the two, whereas others move the AdBlue filler to your boot or under the bonnet. At the petrol pump, your diesel side is topped up constantly. A driver who has to stop and think where it goes usually fills the AdBlue side, from a bottle, and much less frequently. It is in the gap that the slip lives.

AdBlue in the diesel tank around Ham Hill: how it happens

Carelessness seldom causes it. What does is three things coming up at once.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Walcheren Place before work, or in the car park outside The Yachtsman on the way home.

The old car's filler is where the hand goes — but a rental car, a new car or a company car keeps the fillers somewhere else. That is a second thing: an unfamiliar vehicle.

No part stops the pour once it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. Rockley Sands or the heart of Ham Hill: it is the same few seconds either way.

Telling the AdBlue filler from the diesel filler

Before you tip anything, whether on a drive in East Holton or a forecourt around Ham Hill, check these. They take a few seconds.

  • Position misleads; the cap does not. AdBlue ones tend to be blue or bear the name "AdBlue" — diesel ones normally do not.
  • Check the size: the smaller neck is, on plenty of vehicles, the AdBlue one.
  • A label inside your fuel flap frequently says which fuel goes where, on many vehicles. Check for it.
  • In your boot or under the bonnet: that is where your filler sits if it is not by your diesel cap, and the handbook says which.
  • The person who drove it last. On a hire or company car picked up from somewhere like the car park outside Hamworthy, ask before you leave, not when the light comes on.

AdBlue top-ups that never reach the diesel tank

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

  • Not in a rush on the side of Rockley Holiday Park Road, not on a slope, not with your motor running: park then switch off properly.
  • Silly as it sounds, speaking "AdBlue" out loud while you unscrew the cap works — after you have located the filler and read the cap.
  • Leave the diesel cap on. If both sit under one flap, check your diesel cap is still closed before you lift the bottle.
  • Using the bottle's own spout, pour slowly — and stop when it's full or the bottle is empty.
  • Shut the cap, and check again — making sure the diesel cap remained shut throughout. Only then, start the vehicle.

If at step two or three you find you have already poured into your diesel side, stop there. Stage five is off limits.

Put AdBlue in the diesel tank in Ham Hill already?

Then the order of things is short. Don't start the engine. Don't switch the ignition on; on plenty of diesels that alone runs the fuel pump. Diluting it with more diesel fails, because AdBlue sinks to the bottom instead of mixing — and that's where your fuel is pulled from.

If you're at a forecourt, whether it is the Esso or the Shell, ask the attendants to help push your car away from the pump. If you're on your own drive around Ham Hill, leave the car where it stands.

Where your motor has run by now, pull over safely and switch it off. The next junction is where to come off if you are on the M27, under 25 miles from Ham Hill. Distance matters — a short hop across Ham Hill is a smaller job than heading under 50 miles to Salisbury — so say roughly how far it went.

When our engineers turn up in Ham Hill, what occurs?

Our engineers come to your car wherever it has stopped, whether that is outside Bayside Academy, close to Flying Boat fuel depot or on your own drive. We ask what got in, roughly how much, and whether it's run, because the answers determine this work and the quote. You hear that price by phone, before anyone sets off.

Then your tank is emptied and the fuel system flushed thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. The fuel filter is flushed, or replaced where it needs to be; fresh diesel goes in; and your car is tested. After that our technicians start the car and check it runs correctly before we go.

Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which your motor has not run take about half an hour once we are there. Your insurer will ask for the engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no money upfront. Before we get there, take a look at your insurance documents; plenty carry cover for misfuelling.
