AdBlue in a diesel motor, and its separate tank

Diesel feeds your engine — yet many modern diesels seen about Bessbrook and Newry hold a second liquid too. AdBlue's own tank keeps it, and from there it is sent to the exhaust, and there a spray treats the fumes.

Each tank has a filler of its own. Under one flap, side by side: that's the arrangement on many cars. Elsewhere, AdBlue's filler is under the bonnet or in your boot instead. The diesel side is topped up at the petrol 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 regularly. That gap is where the slip lives.

Bessbrook: how AdBlue in your diesel tank takes place

Seldom is it carelessness: usually three things line up.

The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, the vehicle drops into limp mode. So the top-up is done in a hurry: on a driveway off Dunskey Street before work, or in the car park at the pub in the village on the way home.

Next, the hand goes for the cap it knew on the old vehicle — since a rental car, a new vehicle 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. So the tip, after started, keeps on. Whether it takes place in Mullaghglass or the middle of Bessbrook, it is the same few seconds.

How to tell the AdBlue filler from the diesel one

A few seconds is all these take — so run through them before you pour anything, on a driveway in Lurganare or a forecourt around Bessbrook.

  • Check the cap rather than going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel caps usually aren't.
  • Look at the size: the smaller neck is, on plenty of motors, the AdBlue one.
  • Look inside your fuel flap: plenty of cars carry a label there saying which fuel goes where.
  • The handbook. If the filler isn't by your diesel cap, it is in the boot or under the bonnet, and the handbook says which.
  • Picking up a hire or company car, say at the car park outside the nearest station? Ask the person who drove the vehicle last before leaving, not when the light goes on.

How to top up without AdBlue in your diesel tank

On the day the warning comes on — wherever you are in County Armagh — a routine to use.

  • Park then switch off. Not on a slope, not with your engine running, and not in a rush on the side of South Crescent.
  • Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, perhaps, yet it works.
  • Both under one flap? So confirm the lid on the diesel side stays shut before lifting the bottle.
  • Slowly does it, through the bottle's own spout, till it's full or the bottle runs out.
  • Before starting your car, shut the cap and check a second time that your diesel cap was never opened off.

Discover at the second or third stage that AdBlue went in the diesel tank? That is where you stop. Don't go on to step five.

Then the order of things is short. Do not start the motor. On many diesels your ignition alone runs the fuel pump, and so do not switch it on. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is sucked from — so do not top up with diesel to dilute it.

The staff at the nearest petrol station, another forecourt nearby or another forecourt will normally help pushing your car clear if you ask. Leave it where it is if you are on your own drive in Bessbrook.

When the engine has run by now, pull over safely and switch it off. The next exit is where to come off if you're on the M77, over 50 miles from Bessbrook. A short hop across Bessbrook is a smaller job than a run towards Newry, under 3 miles away, so tell us roughly how far it went.

Bessbrook: what occurs when our engineers turn up

Wherever the vehicle came to rest, whether outside the local primary school, beside the centre or on your own drive, our van comes to it. Both the work and our price depend on three answers — which fluid, what quantity, and whether it has run — so our engineers ask. You hear that quote by phone, before anybody heads out.

After that: draining, then a thorough flush of the whole system. Much more than with petrol, it counts here: crystals build up, certain metals corrode, and none of that clears away on its own, however long it is left. Filter cleaned or, if it must be, swapped; fresh diesel in; then a check of your car. We do not go until it has been fired up and is running smoothly.

Using pumps fine on a busy forecourt and quiet enough for use outside a house at night, most jobs where your engine has not run need about half an hour after our engineers are there. Your insurer usually wants the engineer's report and your VAT invoice, and both are yours at the end. Payment comes on the day, with no money upfront. Wrong-fuel cover is part of plenty of insurance policies — and so make use of the wait to look at yours.

Shifting the vehicle is not necessary. Draining takes place on the spot, whether a drive, a street by a street just off the centre, or a layby towards the green space at the edge of the village. Tricky to explain, like the back of the far end of the built-up part? Close to a border? Checking is better than guessing, so ring.
