Two fillers, two tanks: AdBlue in a diesel vehicle

Plenty of modern diesels in Holywood, as well as Jordanstown, run on two fluids; your motor takes just your diesel. Its own tank holds it, and from there it is sent to your exhaust, where spraying treats the gas.

Different tanks, separate fillers. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. The diesel side is filled 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. The mistake grows in that gap between them.

How AdBlue in your diesel tank happens in Jordanstown

Carelessness rarely causes it. Instead is three things lining up together.

On a drive off Chalet Road before work, or in the car park at the pub in the village heading home: that's where the rushed top-up happens. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and once it is gone, limp mode kicks in.

The old car's cap is where the hand reaches — but a rental car, a new vehicle or a company car puts the fillers elsewhere. That's the second factor: a new vehicle.

A spout-topped bottle meets no resistance at a diesel filler no more than at an AdBlue one. So the tip, after started, carries on. The same few seconds settle it, in the middle of Jordanstown or out in Newtownabbey.

How to tell the AdBlue filler from the diesel one

Whether a Jordanstown forecourt or a driveway out in Carrickfergus, take a few seconds over these before anything goes in.

  • Position misleads; the cap does not. AdBlue caps tend to be blue or carry the word "AdBlue" — diesel caps normally don't.
  • Plenty of vehicles fit AdBlue the smaller neck of the two.
  • Look inside the fuel flap: many cars have a label there showing which fuel goes where.
  • Cannot see it beside your diesel filler? In that case look beneath the bonnet or in your boot — the owner's manual says where.
  • Collecting a hire or company car, say at the car park outside the nearest station? Check with whoever drove it last before leaving, not when the light goes on.

Keeping AdBlue out of your diesel tank when you top up

Wherever in County Antrim the light comes on, this is a routine for that day.

  • Pull in on level, motor off, with time in hand — never hurried on the side of North Crescent.
  • Find the AdBlue filler, check the cap, and speak the name "AdBlue" aloud as unscrewing it. It seems silly. It works.
  • If both sit under one flap, check the diesel cap is still closed before you lift the bottle — and leave it on.
  • Gently is best, through the bottle's own spout, until it's full or the bottle is empty.
  • Close the cap, then look once more — making sure your diesel cap remained closed the whole time. Only then, start your car.

If at step two or three you find you have already poured into your diesel side, stop there. Don't go on to stage five.

Jordanstown: already put AdBlue in the diesel tank?

The short order of things, starting with not starting your motor. On many diesels the ignition alone runs the fuel pump, so do not switch the vehicle on. Do not top up with diesel to thin it: AdBlue does not mix with diesel, it sinks to the bottom of your tank, where your fuel is sucked from.

Ask the staff to help roll the car clear of the petrol pump if you're on a forecourt — the the nearest petrol station, the another forecourt nearby or anywhere else. If you are on your own driveway around Jordanstown, leave the vehicle where it stands.

Already started? Pull over once it's safe, then switch off. Jordanstown lies over 50 miles from the M77; on it, take the first exit. A short hop across Jordanstown is a smaller job than a run towards Belfast, under 10 miles away, so tell us about how far it went.

Our arrival in Jordanstown, and what occurs next

Anywhere your car has stopped, whether by the local primary school, beside the centre or on your own drive, the van comes to it. Our engineers ask what was put in, about how much, and whether it has run, since those answers settle the work and our quote. You get that quote by phone, before anyone heads out.

Emptying the tank comes next, then a full flush of the system. Unlike petrol, AdBlue leaves crystals and eats at some fuel-system metals, and none of that washes out unaided. Hence it counts more. Testing comes at the end: before that, fresh diesel goes in, and the fuel filter is cleaned or replaced if necessary. We do not leave until it has been started and is running correctly.

With pumps safe on a busy forecourt and quiet enough to use outside a house at night, most jobs in which the engine has not run take roughly half an hour once our technicians are there. The insurer usually wants an engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no money upfront. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way.

If you are close to a boundary, or somewhere hard to describe like the back of the far end of the built-up part, ring and ask rather than guessing.
