Around Cogry-Kilbride, catching it before the engine turns usually leaves a drain and a thorough flush where it stands. The rest of this page explains why it occurs and how to make sure it doesn't — handy if you are reading before it has happened. ## AdBlue in a diesel vehicle: two tanks, two fillers Not one liquid but two: that is what plenty of modern diesels around Cogry-Kilbride and Ballylinney run, with diesel feeding the engine. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Every tank comes with a filler of its own. Plenty of motors share a single flap for the two, whereas others put the AdBlue filler to your boot or under the bonnet. Topping up the diesel side at the pump happens all the time. The AdBlue side is topped up far less commonly, normally from a bottle, and normally by somebody who has to stop and think where it goes. The error lives in that gap. ## Cogry-Kilbride: how AdBlue in the diesel tank takes place Rarely 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 B738 before work, or in the car park outside the pub in the village on the way home. Next, the hand reaches for the cap it would have used on the old vehicle — because a rental car, a new car or a company car places the fillers where your last one didn't. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, so nothing stops the tip after it has started. It's a few seconds, whether out in Doagh or right in the centre of Cogry-Kilbride. ## The AdBlue filler and the diesel filler: telling them apart Before you pour anything, whether on a drive in Ballyrobert or a forecourt in Cogry-Kilbride, check these. They take a few seconds. - Where it sits can mislead; the cap doesn't. AdBlue caps tend to be blue or carry the name "AdBlue" — diesel ones usually don't. - On plenty of cars, size tells: AdBlue has the smaller filler neck. - Open the flap and look for a label — plenty of cars mark what goes in each inlet just there. - The handbook. If your filler isn't by your diesel cap, it's in your boot or under the bonnet, and the handbook says which. - 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. ## AdBlue top-ups that never reach your diesel tank Wherever around County Antrim the light comes on, this is a routine for that day. - Switch off once parked — level ground, engine stopped, and not rushed beside Chalet Road at the roadside. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Daft, perhaps, yet it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave it on. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Before you start the car, close the cap and look a second time that the diesel cap was never came off. Find during the second or third step that the bottle went in the diesel filler? That is where you stop. Leave out stage five entirely. ## Already put AdBlue in the diesel tank around Cogry-Kilbride? Do not start the engine: that is how the short order of things begins. The fuel pump runs on plenty of diesels as soon as your ignition goes on — so leave it off. Diluting it with extra diesel won't work, since AdBlue sinks to the base instead of mixing — and that's where your fuel is pulled from. Ask the staff to help push your car clear of the pump if you're on a forecourt — the the nearest petrol station, the another forecourt nearby or somewhere else. On your own drive in Cogry-Kilbride?

Those answers determine the work and our price, and so our engineers ask what was put in, roughly how much, and whether it's run. During the call itself, you hear our price — ahead of dispatch. Emptying your tank comes next, then a full flush of the fuel 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 doesn't wash out on its own. After the fuel filter has been cleaned — or renewed, if required — clean diesel is added, and finally the car gets tested. The motor is started next and checked to confirm it runs smoothly, all before we go. If the motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are safe 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. Before we get there, take a look at your policy; many carry cover for misfuelling. ## About Cogry-Kilbride and where it is Cogry-Kilbride is a small locality in County Antrim, situated inland at an elevation of 84 metres, approximately 11.9 miles northwest of Belfast.
