Not run so far? Then leave the vehicle that way, whether your car sits — Ardstraw or Sion Mills. Switch nothing on, ring 0333 366 0103, then expect a proper flush after a drain, done just where the vehicle stands around Ardstraw. Already run? Stop when you safely can, then turn everything off. The job is bigger, but the first stage is the same. Match what happened to a situation from the ones below, anywhere around County Tyrone you are. ## Ardstraw forecourt: AdBlue in a diesel at the pump Just at this point, bottle yet in hand, you realise that the cap you opened was the wrong one, right at the petrol pump. Be it the nearest petrol station, another forecourt nearby or anywhere else in Ardstraw, the situation is identical. Meaning? Finding out here is the best it can be. Nothing has pulled it in, and so the AdBlue stays just inside your tank. What to do: do not get back in and crank it to clear the petrol pump. Have the attendants to help pushing it into a bay, save the bottle, then ring us from there. Can't move the vehicle by the petrol pump? Explosion-proof equipment makes a live forecourt safe, so it can be drained where it is. ## AdBlue in the diesel tank on a Ardstraw drive? Several days had gone by with the warning light on. You bought a bottle, poured it in on the drive, and only when you put the empty bottle in the recycling did you look a second time at the cap. Drives near Rock Street get it as much as anywhere. Meaning? As long as the car has not moved since, it is second to the pump case. At the floor of your tank sits exactly where AdBlue waits, since it won't blend with diesel — and a night passing makes nothing of the difference. Your move: keys indoors, and so nobody drives the car off first thing. Then, ring. Our technicians drain it on your driveway, whether that is in Ardstraw or out in Victoria Bridge. The pumps are quiet enough to use outside a house at night. ## Ardstraw: set off with AdBlue in a diesel? Rough running, smoke, lost power or a glowing dashboard started a short way beyond the fill. Crom Street, say, or the route to Derry — a run of under 25 miles. Meaning? Your pump has taken the AdBlue up. It has been through the filter and the fuel lines and, the further you went, into the high-pressure fuel pump and the fuel injectors. More miles, more restarts: deeper it goes. What to do: pull over where it is safe to do so and switch off. Service stations farther on are too far: from the M77, over 50 miles out of Ardstraw, use the next junction. It will not have cleared, so there is no point starting it again to find out. Let us know the mileage driven as you ring. ## A hire or company car with AdBlue in the wrong tank? It's a vehicle you have had for a week. Unbeknown to you, the AdBlue and diesel inlets sit next to each other here — unlike your own car, which has no AdBlue or keeps it elsewhere. It can happen to anyone, anywhere across County Tyrone. What it means: the same as the situations above, depending on whether it's run, with one more stage. Plenty of hire and company contracts require the owner's approval before repairs. Next: phone the rental company or your fleet manager first, and then us — sorting it before our arrival is faster. If you are stuck in the car park at the nearest station, or by the centre, while you wait for an answer, leave the car off. ## Unsure about AdBlue in your diesel tank around Ardstraw? At times the honest answer is "I think so". Lighter, the bottle; a hint of ammonia near your filler; no clear recollection of which cap. Sound familiar? The gates of the local primary school in a hurry, perhaps, or someone's driveway out in Erganagh. Meaning? Drips outside the inlet never reach the motor at all. AdBlue inside the diesel tank does. If there is AdBlue in that tank, starting the vehicle will suck it in, and it would not tell you which either. What to do: treat it as if it got in. Do not crank it. Ring with what you saw: we'd rather find a tank free of AdBlue than empty one once your motor has run. ## The common ground in every Ardstraw AdBlue drain Whichever situation you are in, the job starts the same way. Three things are asked once our engineers reach the car — 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 amount, and if the motor has been started. Answers shape the job; the price comes on the call whilst no one has set off yet. AdBlue forms crystals and eats at some metals in fuel systems, so it does not wash out on its own; that's why the flush, after the drain, matters much more here than with petrol. Next comes the fuel filter — flushed, or swapped when necessary — followed by fresh diesel, and a test of the vehicle. The majority of unrun vehicles are a half-hour job from the moment we turn up. Lastly, our engineers start it. We check it runs smoothly on fresh diesel before leaving. Permanent damage is very uncommon when it is spotted soon, and the whole job is done where the vehicle is. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Plenty of insurance policies include misfuelling cover, so it is worth checking yours while we are on the way. ## About Ardstraw itself Ardstraw is a small locality in County Tyrone, situated inland at an elevation of 34 metres, and is located near the towns of Victoria Bridge, Douglas Bridge, and Newtownstewart.

Fastest of all: a BT78 4 postcode for your location. No moving is needed, be it stopped centrally in Ardstraw or in a layby en route to the green space at the edge of the village, and so leave it where it is. Our engineers drain the vehicle where it is. Phone and ask rather than guess if you're by the far end of the built-up part, near a border, or somewhere awkward to explain. ## Your situation, summed up Still unrun?
