Then put this page down for now, keep your ignition and motor off, then call 0333 366 0103. A drain and a full flush, carried out right where the vehicle stands in Wootton, is usually what it takes when caught before the motor runs. Here in advance? Then what follows covers why it happens and what to prevent it happening at all. ## Why does AdBlue in a diesel car need its own filler? No single liquid but two: that is how plenty of modern diesels around Wootton and Merefield run, with diesel feeding the engine. Your exhaust, not the engine, is where AdBlue goes: dosed into the fumes to clean it, from a separate tank. Each tank has its own filler. Many of motors share a single flap for both, while some put the AdBlue filler to the boot or under the bonnet. The diesel side is fuelled at the pump all the time. The AdBlue side is filled far less commonly, usually from a bottle, and normally by somebody who has to stop and think where it goes. That gap is where the slip lives. ## Wootton: how AdBlue in your diesel tank occurs Three things tend to come together, and carelessness is rarely one of them. The warning comes first. As AdBlue runs low your car tells you, and if it runs out altogether, your vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Farmclose Road before work, or in the car park outside Yeoman of England on the way home. The old car's filler is where the hand goes — but a hire car, a new car or a company car puts the fillers somewhere else. That is a second factor: an unfamiliar vehicle. And the bottle fits. A bottle with a spout goes into a diesel filler as easily as an AdBlue one, and so nothing stops the tip after it has started. Hardingstone or the heart of Wootton: it is the same few seconds either way. ## The AdBlue filler and your diesel filler: telling them apart Look at these first, on a forecourt in Wootton or a drive over in Brackmills. Seconds, that's all. - Read the cap rather than going by where it sits: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones usually aren't. - On many cars, the size tells: AdBlue gets the smaller filler neck. - Check inside the fuel flap: many vehicles have a label there saying which fuel goes where. - The handbook. If the filler is not by your diesel cap, it is in the boot or under the bonnet, and the handbook says which. - The previous driver will know. Check when you pick up a hire car or company car — from Northampton's car park, perhaps — not once the light appears. ## Topping up AdBlue without it reaching your diesel tank When the light comes on, wherever around Northamptonshire, use this routine. - Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Water Lane. - Say "AdBlue" out loud as you unscrew the cap, once you find the AdBlue filler and read it. Daft, perhaps, yet it does the trick. - The two behind one flap? So make sure the cap on the diesel filler is still shut before lifting the bottle. - Finish when the tank fills or the bottle runs dry; until then, pour slowly through its own spout. - Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start the car. Discover during the second or third step that the bottle went in the wrong filler? That's where you stop. Stage five is off limits. ## Put AdBlue in your diesel tank around Wootton already? Brief list, then. Top of that: the motor stays off. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch the vehicle on. Diluting it with more diesel won't work, since AdBlue sinks to the base instead of mixing — and that is where your fuel is pulled from. If you are at a forecourt, whether it is the Shell or the BP, ask the staff to help push the car clear of the petrol pump. Leave it where it is if you are on your own drive around Wootton. Where your motor has run already, stop safely and switch the vehicle off. On the M1, under 3 miles from Wootton, that means the next junction. Distance matters — a quick hop across Wootton makes a smaller job than heading under 15 miles to Milton Keynes — so tell us roughly how far it went. ## When our technicians get there in Wootton, what takes place? The van comes to the vehicle wherever it has come to rest — your own drive, beside Wootton Memorial Hall, or by Wootton Primary School. Both the work and our quote depend on three replies — which fluid, which amount, and whether it has run — so our engineers ask. That price comes over the phone, ahead of any van leaving. Then your tank is cleared and the system flushed thoroughly. With AdBlue that counts more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. Filter flushed or, where it must be, replaced; fresh diesel in; and then a check of the vehicle. The engine is started next and checked to make sure it runs correctly, all before our technicians go. If your engine hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. Many insurance policies include misfuelling cover, so it's worth checking yours whilst we're on the way. ## About Wootton Wootton is a suburban area in Northamptonshire, situated approximately 12 miles from Milton Keynes and 58 miles northwest of London.
