What to do about AdBlue in a diesel tank depends on one thing more than any other: whether your engine has run since it got in. Out in Boothville or right around Round Spinney, an unrun engine should stay that way. Usually this is draining and thoroughly flushing it right there around Round Spinney — so keep your key and motor off then ring 0333 366 0103. If it has run, stop as soon as it is safe then switch off. Step one remains unchanged, even if the job is bigger. Wherever across Northamptonshire it happened, one of the situations below fits yours. ## AdBlue in a diesel on a Round Spinney forecourt The cap you unscrewed was the wrong one — and you just notice it as you are standing at the pump, bottle or the nozzle in your hand. Anywhere in Round Spinney, then — Shell, Tesco, or anywhere else nearby. Put simply: no better place exists to discover it. Still inside the tank, and no fuel pulled through: that's where the AdBlue is. What to do: do not get back in and crank it to clear the pump. Have the staff to help rolling it into a bay, save the bottle, then ring us right there. Emptying it right at the pump is possible if it cannot be shifted, because the equipment is explosion-proof. ## Round Spinney, at home: AdBlue in your diesel tank Several days had passed with the warning light on. Only at the recycling bin, the empty bottle in hand, did you glance back at the cap you'd used at the driveway. It takes place on driveways just off Edgemead Close as commonly as anywhere. The point: no miles since leaves this almost as good to spotting it at the pump. AdBlue doesn't mix with diesel; it sinks to the bottom of your tank and waits there. Overnight doesn't change that. Put the keys indoors overnight — or a person may drive it away at breakfast — then phone us. Out in Southfields or here around Round Spinney, the draining is done at your drive. Even at night, the pumps stay quiet enough for a driveway. ## On the road in Round Spinney with AdBlue in a diesel Lumpy running, smoke, falling power or a lit dashboard started a mile or two after the fill. Maybe driving for Milton Keynes, under 25 miles away, or simply down North Portway Close. What it means: the fuel system has drawn the AdBlue in. The injection pump and each injector see it too on a longer run, once the fuel filter and lines have it. Each mile and each restart takes it further. Your move: stop anywhere sensible, then switch your motor off. On the M1, under 10 miles from Round Spinney, that means the next junction, not the services further on. Do not restart the car to see if it has cleared; it will not have. Phone, and say how far your car went. ## Hire, lease or company car with AdBlue in the wrong tank A week back, the car was new to you. Unbeknown to you, the two inlets are side by side here — not like your own vehicle, which has none or keeps it in another spot. Wherever you happen to be around Northamptonshire, any driver could slip up. Put simply: an extra step on top of the cases above, which turn on if it has run. Many rental and fleet agreements require the owner's approval before repairs. What to do: ring the hire firm or your fleet manager first, then us. That is quicker settled before we get there than after. Waiting for an answer at the car park outside Northampton, or near Thorplands Community Hub? Leave the car off throughout. ## AdBlue in the diesel tank? Not sure, around Round Spinney "I think so" is sometimes the most honest as it gets. Lighter, that bottle; a hint of ammonia near the filler; a hazy recollection of the cap. Look familiar? It might have been on a friend's drive in Moulton Leys, or in a rush outside Thorplands Primary School at the school run. The upshot: your engine is not hurt by some AdBlue splashed on the outside. In the diesel tank, however, AdBlue harms it. Turning on the vehicle will not tell you which, and if there is AdBlue in that tank it will pull it in. Take it that it got in, and don't turn the engine. Checking a tank that proves clean beats draining one once it's been run — so phone then tell us what you noticed. ## The common ground in every Round Spinney AdBlue drain The job begins the same way, whichever your situation. Three things come when we arrive — at a forecourt, a driveway, a road beside Moulton Community Library or the car park at The Gallery: the fluid, the amount, and whether it has run. Answers set the job; the price comes on the call whilst nobody has left yet. Then that tank is cleared and your system rinsed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own. Next comes your filter — cleaned, or replaced where needed — then fresh diesel, and a test of the vehicle. Where your engine hasn't run, expect about half an hour on site, for most cases. Our engineers fire it up at the end. We make sure it runs properly on fresh diesel before leaving. Our technicians do the entire job where the vehicle is, and permanent damage is very uncommon if it has been noticed soon. Paying is that day, never in advance. For your insurer, there is a VAT invoice and a written report from the engineer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we are on the way. ## About Round Spinney, for a moment Round Spinney is a suburban area in Northamptonshire, situated inland at an elevation of 92 metres, and is located near the cities of Milton Keynes and Northampton.
