Find Your Situation All of that turns on a single detail: whether the motor has been run since the AdBlue went in — more than anything else. Out in Tynan or right around Madden, an unrun engine must stay that way. Normally this is draining and thoroughly rinsing it on the spot in Madden — so leave the ignition and motor off and phone 0333 366 0103. If it's run, stop as soon as it is safe then switch off. The job is bigger, but the first stage is the same. Wherever around County Armagh it happened, one of the cases below fits yours. ## On a Madden forecourt with AdBlue in a diesel Just now, bottle still in your hand, you realise that the cap you opened was the wrong one, right at the pump. Whether the nearest petrol station, another forecourt nearby or anywhere else in Madden, the case is the same. Put simply: there is no better spot to be to spot it. Still in that tank, and nothing drawn through: that's where the AdBlue sits. Next: avoid the urge to start it just to free up the petrol pump. Ask the staff to help you push your car into a parking spot, keep your receipt or the bottle, and ring us from the forecourt. If it cannot be shifted, it can be drained at the pump: the equipment is explosion-proof and fine on a busy forecourt. ## AdBlue in your diesel tank at home in Madden On the dash, a reminder had shown all week. A bottle bought at the shop, tipped in at the driveway — and it's only at the bin that the cap caught your eye. Right off South Crescent is no less likely from anywhere. Put simply: if your vehicle hasn't moved since, it's almost as good as finding out at the pump. On the bottom of your tank is where AdBlue waits, since it won't mix with diesel — and a night passing changes nothing of the difference. Next: stop any early-morning drive by putting the keys in the house, then phone us. Your drive is where it is emptied, whether around Madden or Middletown. The equipment works quiet enough not to disturb the street at night. ## Set off with AdBlue in a diesel around Madden? You filled up, set off, and a mile or two later the engine began to run roughly, smoke, lose power or light up the dashboard. Dunskey Street, perhaps, or the route towards Armagh — a trip of under 10 miles. Meaning? The pump has taken the AdBlue up. It's been through your filter and your lines and, the further you went, into the high-pressure fuel pump and the injectors. It travels further with each mile covered and each restart. What to do: pull over where it is safe to do so then switch off. On the M77, over 50 miles from Madden, that means the next exit, not the services further on. No test restarts: clearing itself isn't something AdBlue will do. Roughly how far did it go? Tell us when you call. ## Hire, lease or company car with AdBlue in the wrong tank Seven days ago, it was unknown to you. The AdBlue filler sits right beside the diesel one, which you did not know, since your own vehicle either has no AdBlue or keeps it somewhere else. It can happen to anyone, anywhere around County Armagh. The point: exactly as above, split by if it ran, but with an added step. Plenty of hire and company agreements want the owner to approve work on your car. What to do: call the hire firm or your fleet manager first, then us. That is faster settled before we turn up than after. Leave the car off as the reply comes, whether you are waiting at the nearest station or near the centre. ## Unsure about AdBlue in the diesel tank in Madden? Occasionally the honest answer is "I think so". The bottle is lighter than it should be, there is a faint smell of ammonia about your filler, and you can't remember which cap you took off. The gates of the local primary school in a rush, perhaps, or someone's drive out in Killylea. Meaning? Spills outside the filler don't touch the motor at all. If it's inside the diesel tank, though, it does. If there is AdBlue in the tank, firing up the vehicle would pull it in, and it wouldn't tell you which either. Next: act as though it got in, and leave your engine off. Ring us and explain what you saw; we would rather check a tank that turns out clean than drain one that has already been run. ## Each AdBlue drain in Madden shares these stages Whatever the case, one start applies. Anywhere the car is — the pub in the village's car park, a street by a street just off the centre, a driveway, a forecourt — the van gets there and asks for the fluid, the amount, and whether the engine has been run. Your price comes on the call, before a van leaves, and those replies set the job. AdBlue crystallises and is corrosive to certain metals in fuel systems, so it won't wash out on its own; that is why the flush, after the drain, matters far more here than with petrol. Last are the fuel filter, flushed or replaced as needed; fresh diesel; and a test of the car. If your motor hasn't run, most jobs take about half an hour once we're there. We fire it up at the end. Our check that it runs correctly on fresh diesel comes before we head off. Our engineers do the entire job where the vehicle is, and permanent damage is very unusual if it has been noticed soon. 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're en route: cover for misfuelling is built into plenty of policies. ## About Madden itself Madden is a small locality in County Armagh, situated inland at an elevation of 89 metres, approximately 6.5 miles from the city of Armagh.
