One thing matters above all when AdBlue is in a diesel tank, and that is if your engine has run since. Not run yet? Then leave the vehicle like that, wherever the car is — Kilrea or Tamlaght. Leave the motor and your ignition off then call 0333 366 0103; it's normally a drain and a thorough flush, done where the vehicle is around Kilrea. Pull over the minute it is safe then switch off, if it has already run. The job is bigger, yet the first step is the same. Find the scenario below that matches yours, wherever across County Londonderry it happened. ## On a Kilrea forecourt with AdBlue in a diesel The cap you unscrewed was the wrong one — and you just notice it while you're standing at the pump, bottle or the nozzle in hand. Be it the nearest petrol station, another forecourt nearby or somewhere else in Kilrea, the case is identical. Meaning? Spotting it on the forecourt is the best it gets. Nothing has pulled it through, and so the AdBlue stays just in that tank. Next: avoid the urge to start it just to move away from the pump. Have the attendants to help rolling it to a space, save the receipt, then phone us right there. Can't move the vehicle beside the petrol pump? Explosion-proof equipment makes a live forecourt sensible, and so we can drain the car in place. ## AdBlue in your diesel tank at home in Kilrea On your dash, a reminder had shown all week. Only at the recycling bin, the empty container in hand, did you look back at the cap you'd used at the drive. Right off Wallace Cottages is no different from any other place. Meaning? As long as the car has not been driven since, it's close to the pump case. As it is reluctant to blend, AdBlue settles to the base in your tank and waits. One night parked alters none of that. Next: stop any early-morning drive by keeping the keys indoors, then phone us. Garvagh or Kilrea: whichever your driveway sits, that is where it gets emptied. Our equipment runs quietly enough that it won't wake the street at night. ## Drove off with AdBlue in a diesel around Kilrea? You filled up, set off, and a mile or two later the motor began to run unevenly, smoke, lose power or light up the dashboard. Perhaps it was on Dunaverty Court, perhaps on the way out towards Derry, under 50 miles away. Meaning? Your fuel pump has sucked the AdBlue up. It has been through the filter and the lines and, the further you went, into the high-pressure pump and your injectors. Each mile and each restart takes it further. Next: find a sensible place, pull in, then turn the engine off. Leave by the first junction — not the services beyond — if you're on the M77, over 50 miles from Kilrea. Starting it again to check achieves nothing — AdBlue never clears itself. Roughly how far had it gone? Say so as you phone. ## AdBlue in the wrong tank: hire, lease and company vehicles It's a motor you have had for a week. Unbeknown to you, the AdBlue and diesel inlets sit next to each other here — not like your own vehicle, which has none or stores it elsewhere. Across County Londonderry, nobody is safe from it. What it means: the same as the situations above, depending on whether it's run, with one more step. Any work on the car often requires the owner's go-ahead under hire or company terms. What to do: call the hire firm or your fleet manager first, then us. That is faster settled before our engineers get there than after. If you are stranded in the car park at the nearest station, or by the centre, whilst you wait for an answer, leave the car off. ## Unsure about AdBlue in your diesel tank around Kilrea? Now and then, "I think so" is all you can honestly say. Too light, the bottle; a trace of ammonia round your filler; no clear memory of which cap. Look familiar? The gates of the local primary school in a rush, perhaps, or someone's drive over in Aghadowey. In short: spillage near your filler does the motor no harm. If it's inside your diesel tank, though, it does. If there is AdBlue in that tank, starting your car would pull it in, and it would not tell you which either. What to do: treat it as if it went in. Do not fire it up. Tell us what you noticed on the phone. A clear tank checked counts as a happier result than a run one drained. ## Kilrea: what every AdBlue drain has in common The work opens identically, whatever your case. Three questions come once our technicians arrive — on a forecourt, a drive, a street by a street just off the centre or the car park outside the pub in the village: the fluid, the quantity, and if it has run. Answers shape the job; the price follows by phone while nobody has set off yet. Draining the tank comes next, then a careful flush — more important with urea than after petrol, since crystals and corrosion will not clear on their own, however long you wait. Clean diesel goes in once your filter has been cleaned or replaced, and your car is finally checked. If your engine hasn't run, most jobs take about half an hour once we're there. Lastly, our engineers fire it up. Our check that it runs correctly on fresh diesel comes before our technicians head off. The whole job is done where your car is, and if it's caught quickly, long-term damage is very uncommon. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies cover misfuelling, so look at yours as we head over. ## About Kilrea and where it is Kilrea is a small locality in County Londonderry, situated inland at an elevation of 38 metres.
