--- title: Kilmore: AdBlue in a Diesel Tank, What Next canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/kilmore-county-down/ location: Kilmore county: County Down latitude: 54.388000 longitude: -5.786700 service: AdBlue in a Diesel Tank updated: 2026-10-15 --- # What Now? AdBlue in the Diesel Tank in Kilmore What to do about AdBlue in a diesel tank comes down to one thing more than any other: if the motor has been run since it went in. Over in Loughinisland or here in Kilmore, an unrun engine must remain that way. Normally that is emptying and thoroughly purging it right there in Kilmore — so leave the key and engine off and call 0333 366 0103. Already started? Stop when you safely can, then turn everything off. The job is bigger, but the first stage is the same. Below: the cases we meet, anywhere across County Down. Choose the one that fits. ## AdBlue in a diesel on a Kilmore forecourt Only at this point, bottle still in hand, you realise that the cap you opened was the wrong one, there at the pump. Perhaps you're at the the nearest petrol station, maybe at the another forecourt nearby, possibly somewhere else in Kilmore. Meaning? Finding out here is as good as it can be. Only that tank holds AdBlue; not one part beyond it has taken it in. Do this: keep out of the driver's seat, even if the queue wants freeing. Get the attendants to lend a hand pushing it to a space, hold on to the receipt, then ring us from there. Can't move the vehicle beside the petrol pump? Our explosion-proof equipment makes a live forecourt safe, so it can be drained where it is. ## AdBlue in your diesel tank at home in Kilmore The warning light had been on for days. You bought a bottle, poured it in on the driveway, and only when you put the empty bottle in the recycling did you look a second time at the cap. Drives close to B7041 get it as much as any other street. What it means: if you haven't driven since, this is nearly as good as the forecourt. Being reluctant to blend, AdBlue settles low inside that tank and stays. One night standing changes none of that. Put the keys indoors overnight — otherwise a person may drive it off at breakfast — then phone us. Your drive is where it is emptied, be it in Kilmore or Crossgar. The pumping kit runs quiet enough not to disturb the neighbours at night. ## AdBlue in a diesel and already driving in Kilmore? A mile or two beyond filling up, the engine began misbehaving: roughness, smoke, less power, lights on the dash. Anywhere on B7065 or on the road to Lisburn — under 15 miles away. Meaning? The fuel pump has sucked the AdBlue in. Past your filter, through the pipework, and — the more the mileage — on into the injection pump and every injector. It travels deeper with every extra mile covered and every restart. Pull in safely — that's the first job — then turn everything off. On the M77, over 50 miles from Kilmore, that means the next exit, not the services further on. No trial restarts: clearing is not something AdBlue does. Call, and say how far the car was driven. ## Hire, lease or company car with AdBlue in the wrong tank Seven days ago, it was unknown to you. On your own vehicle, AdBlue is missing or elsewhere. On this one, the cap is just next to the diesel cap — a surprise to you. Anyone, wherever across County Down, could make the same. Meaning? Whichever case above counts too — run or unrun — and one further step. Many hire and fleet contracts require the owner's sign-off for repairs. What to do: ring the hire firm or your fleet manager first, then us. That is faster settled before our engineers turn up than after. If you are stranded in the car park outside the nearest station, or by the centre, whilst you wait for an answer, leave the vehicle off. ## AdBlue in your diesel tank? Not sure, around Kilmore Occasionally the fair answer is "I think so". A faint ammonia smell lingers near the filler, the bottle feels too light, and which cap came off is hard to recall. The gates of the local primary school in a hurry, say, or a friend's drive over in Ballynahinch. Put simply: a spill near the filler leaves the engine no harm. Inside the diesel tank, however, AdBlue damages it. Any AdBlue in your tank will be sucked in by turning on your car, and the start would not settle which it is in any case. What to do: treat it as if it was put in. Do not start the vehicle. Checking a tank that turns out clean beats draining one once it has been run — so ring and tell us what you saw. ## Every AdBlue drain around Kilmore shares these steps Whatever the situation, a single opening is used. Forecourt, drive, the pub in the village's car park or a street beside a street just off the centre — our van reaches the vehicle, and three answers follow: which fluid, what amount, and if it has run. Replies set the work; the price follows on the call whilst nobody has left yet. AdBlue forms crystals and eats at some metals used in fuel systems, so it does not rinse out on its own; that's why the flush, after this drain, counts much more with AdBlue than with petrol. Clean diesel is put in once the filter has been flushed or replaced, and the car is then tested. If the motor has not run, most jobs take about half an hour once we're there. We start the engine last. Our engineers check it runs smoothly on clean diesel before we go. Long-term damage is very unusual when it's spotted early, and the entire job is done where your car is. Nothing is paid upfront, payment happens on the day, and you get what the insurer wants: an engineer report plus a VAT invoice. Worth knowing: many insurers offer misfuelling cover, so a quick look at your policy as you wait is worthwhile. ## About Kilmore itself Kilmore is a small locality in County Down, situated inland at an elevation of 26 metres, approximately 13 miles from Lisburn.
