AdBlue in a diesel motor, and its separate tank

Many newer diesels in Carrybridge, as well as Lisnaskea, run on two liquids; the engine takes just your diesel. The exhaust, not your motor, is where AdBlue goes: dosed into the gas to fresh it, from a separate tank.

Different tanks, different fillers. Plenty of vehicles have a single flap for the two, while some put the AdBlue filler to your boot or under the bonnet. At the petrol pump, the diesel side gets filled all the time. The AdBlue side is topped up far less frequently, normally from a bottle, and normally by someone who has to stop and think where it goes. The mistake lives in that gap.

AdBlue in the diesel tank in Lisnaskea: how it takes place

It's rarely carelessness. Three things tend to line up.

Hurry follows from the warning. Your car warns you as AdBlue runs low, and a dry tank sends the vehicle into limp mode — so the top-up happens quickly, before work on a drive off Chalet Road, or on the way home in the car park outside the pub in the village.

The old car's cap is where your hand goes — yet a hire car, a new motor or a company car keeps the fillers somewhere else. That is a second thing: an unfamiliar motor.

Third, the bottle goes in: a diesel filler or AdBlue one, it goes in just as easily, and once the tip begins, no part stops it. Donagh or the heart of Lisnaskea: it takes the same few seconds in both.

Flushing a diesel fuel system after AdBlue, Lisnaskea

How to tell the AdBlue filler from the diesel one

A few seconds is all these take — so run through them before you tip anything, on a driveway in Newtownbutler or a forecourt in Lisnaskea.

  • Colour and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually doesn't. Trust the cap, not its position.
  • Look at the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one.
  • The flap. Look inside the fuel flap for a label. Plenty of motors say there which fuel goes where.
  • The handbook says which it lives when the filler isn't next to your diesel cap: your boot, or under the bonnet.
  • Check with the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park at the nearest station.

How to top up without AdBlue in your diesel tank

Wherever in County Fermanagh the light comes on, here is a routine for that day.

  • Park and switch off. Not on a slope, not with the motor running, and not in a rush on the side of North Crescent.
  • Say "AdBlue" out loud as you unscrew the cap, once finding the AdBlue filler and read it. Silly, yes, but it works.
  • The diesel cap remains on. When both sit under a flap, confirm it is shut before lifting the bottle.
  • Stop when the tank fills or the bottle runs dry; before that, tip slowly using its own spout.
  • Shut the cap, and check again — confirm your diesel filler stayed closed throughout. Only then, start your car.

Find during the second or third step that AdBlue went in the diesel tank? That's where you stop. Stage five is off limits.

AdBlue in the diesel tank already, around Lisnaskea?

Then the order of things is short. Don't start the engine. The fuel pump starts on plenty of diesels as soon as the ignition goes on — so leave it off. AdBlue doesn't mix with diesel — it sinks to the bottom of the tank, where your fuel is drawn from — so don't top up with diesel to thin it.

Ask the attendants to help push 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. Your own driveway in Lisnaskea is the place it stays.

Stop as soon as it is safe and switch off, if your motor has already run. Lisnaskea lies over 50 miles from the M77; there, take the first exit. Tell us roughly how far it went: a run towards Armagh, under 50 miles away, is a bigger job than a short hop across Lisnaskea.

Lisnaskea: what occurs when our technicians get there

By the local primary school, close to the centre or on your own drive: wherever your car has stopped, our technicians come to it. Which liquid was put in, the quantity, and whether it ran: we ask since the answers decide both work and price. The quote is given on the call, ahead of any van leaving.

Then that tank is drained and your system rinsed thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it doesn't wash out on its own. The filter is flushed, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. We do not go until it has been started and is running correctly.

Unrun vehicles mostly mean a half-hour job after arrival. The kit is fine on a live forecourt, and hushed enough for a driveway after dark. Nothing upfront; you settle up that day. At the end, a VAT invoice and the report from the engineer are handed to you for the insurer. Before we get there, have a look at your policy; plenty include cover for misfuelling.

The car does not need to move. The drain happens right there, whether a drive, a road by a street just off the centre, or a lay-by on the way to the green space at the edge of the village. Awkward to explain, like the back of the far end of the built-up part? Close to a county line? Asking beats assuming, and so ring.
