One fact counts most when AdBlue is in a diesel tank, and that is if your engine has been started afterwards. Wherever the car stands — Burren, Mayobridge — don't run a motor that hasn't been started yet. Phone 0333 366 0103 with the key and motor both off. In Mayobridge, that is generally emptied and cleaned on the spot. Where your engine has been run, pull in somewhere safe first, then turn the car off. It is a larger job, though stage one doesn't change. Match your case to one of the list below, anywhere in County Down you are. ## On a Mayobridge forecourt with AdBlue in a diesel Picture it: standing by the petrol pump, gripping the bottle, you realise the cap you opened was not the correct one. Be it the nearest petrol station, another forecourt nearby or somewhere else in Mayobridge, the case is identical. Meaning? Finding out here is as good as it gets. Still inside the tank, and nothing drawn through: that is where the AdBlue is. Next: resist the temptation to fire it up just to free up the pump. Phone us from the forecourt after your car is in a bay — the attendants will help roll it — then keep the bottle. Stuck by the pump? Our explosion-proof equipment keeps a live forecourt sensible, and so it can be drained where it is. ## AdBlue in your diesel tank at home in Mayobridge The warning light had been on for days. Bought a bottle, poured it in at home, recycled the empty — and only then checked the cap a second time, too late. It takes place on drives just off B7041 as frequently as anywhere. Meaning? Provided your vehicle has not been driven since, it is close to the pump case. AdBlue doesn't mix with diesel; it sinks to the bottom of the tank and waits there. Overnight does not change that. Next: prevent an early move by putting the keys indoors, then ring us. We drain the car on your driveway, whether that is in Mayobridge or out in Sheeptown. Even at night, our pumps are quiet enough for a driveway. ## Mayobridge: set off with AdBlue in a diesel? Lumpy running, smoke, lost power or a lit dashboard arrived a mile or two beyond the fill. Maybe it was on B7065, maybe on the way out towards Newry, under 5 miles away. Put simply: the AdBlue has been sucked into the system. It has been through your filter and your lines and, the further you went, into the high-pressure pump and the injectors. Each restart, like every mile, pushes it deeper. Your move: stop somewhere sensible, then turn your motor off. Service stations farther on can wait: from the M77, over 50 miles out of Mayobridge, take the first junction. Don't restart the car to see if it has cleared; it will not have. Ring us and say how far you travelled. ## AdBlue in the wrong tank: hire, lease and company cars A week back, it was unknown to you. Your own motor either does without AdBlue or keeps it elsewhere, and so no one told you the AdBlue inlet sits just beside your diesel. Anywhere you happen to be in County Down, every motorist could slip up. The point: just as above, split by whether it ran, only with one added step. Plenty of hire and company agreements want the owner to approve work on the car. Sorting it before the van arrives is faster, so ring the hire company or your fleet manager, and then us. Keep the car switched off as the answer comes, whether you are parked outside the nearest station or close to the centre. ## Unsure about AdBlue in the diesel tank in Mayobridge? "I think so" is often the most honest answer there is. What cap was taken off, you can't say; but the bottle feels less than it ought to, and a whiff of ammonia hangs by your filler. Possibly it happened in a hurry at the school gates at the local primary school, or on a friend's drive in Corbet. Put simply: a spill near the filler leaves your motor no harm. If it's inside your diesel tank, though, that changes. Any AdBlue in your tank would be drawn in by starting the car, and the start would not settle which it is in any case. Next: assume it got in, and keep the motor off. Tell us what you noticed on the phone. A clean tank looked at counts as a happier result than a run one emptied. ## Each AdBlue drain around Mayobridge shares these stages The work opens identically, whichever your case. Our technicians come to your car, whether it's on a forecourt, a driveway, the car park outside the pub in the village or a side street close to a street just off the centre, and ask three things: what got in, about how much, and whether the engine has run. Your price is given over the phone, ahead of anyone setting off, and those replies shape the work. AdBlue crystallises and is corrosive to some metals used in fuel systems, and so it won't rinse out on its own; that's why the flush, after the drain, matters far more here than with petrol. Last are the fuel filter, flushed or replaced as needed; clean diesel; and a check of your car. If the motor hasn't run, the majority of jobs take about half an hour once we are there. The final step is firing it up. Our engineers confirm it runs properly on clean diesel before we leave. If it is spotted early, the car very rarely has long-term damage, and the entire job takes place where it is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Check your insurance while we arrive: misfuelling cover is included in many policies. ## About Mayobridge, briefly Mayobridge is a small locality in County Down, situated inland at an elevation of 117 metres, approximately 4.9 miles from Newry.
