Then set this page down for now, leave your ignition and engine off, then phone 0333 366 0103. Around Nuncargate, finding it before the engine turns usually leaves a drain and a thorough flush on the spot. The rest of this page covers why it occurs and how to make sure it doesn't — handy if you are reading before it has happened. ## AdBlue in a diesel motor, and its separate tank No single fluid but two: that's what many modern diesels around Nuncargate and Bentinck Town carry, with diesel for your engine. AdBlue's own tank keeps it, and from there it goes to the exhaust, and there spraying treats the fumes. Different tanks, different fillers. Under one flap, next to each other: that's the arrangement on a lot of vehicles. Elsewhere, AdBlue's filler sits under the bonnet or in the boot instead. Topping up the diesel side at the pump goes on constantly. Seldom filled, AdBlue normally comes out of a bottle, tipped by a driver who has to stop and think what cap it needs. It's in that gap that the error lives. ## How AdBlue in your diesel tank occurs around Nuncargate Three things tend to come together, and carelessness is rarely one of them. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out completely, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Carr Farm Road before work, or in the car park at Cricketers Arms on the way home. Then, your hand reaches for the cap it would have used on the old car — because a hire car, a new vehicle or a company car puts the fillers where your last one didn't. Nothing halts the tip after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's seconds, be it out in Kirkby Woodhouse or bang in the heart of Nuncargate. ## How to tell the AdBlue filler from the diesel one A few seconds is all these take — so run through them before you pour anything, on a drive in Kirkby-in-Ashfield or a forecourt around Nuncargate. - Read the cap instead of going by position: AdBlue caps are commonly blue or marked "AdBlue", and diesel ones usually aren't. - The size. On plenty of vehicles the AdBlue filler neck is the smaller of the two. - Lift the flap and check for a label — plenty of cars mark which belongs in which inlet right there. - The handbook says which it lives if the filler isn't next to the diesel cap: your boot, or under the bonnet. - Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Kirkby in Ashfield. ## How to top up without AdBlue in your diesel tank The day the light comes on, wherever around Nottinghamshire, use this routine. - Not in a rush on the side of Edison Street, not on a slope, not with the engine running: park then switch off properly. - Find the AdBlue filler, check the cap, and say the name "AdBlue" aloud while you unscrew it. It seems daft. It does the trick. - Both behind one flap? Then make sure the cap on your diesel side stays closed ahead of raising the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Close the cap and check once more. Make sure the diesel cap was never opened. Only then start the car. If at step two or three you find you have already poured into the diesel side, stop there. Never carry on to step five. ## AdBlue in the diesel tank already, around Nuncargate? The short order of things, starting with not starting your engine. Leave the ignition off too, since on plenty of diesels switching it on by itself starts the fuel pump. Don't top up with diesel to thin it: AdBlue doesn't mix with diesel, it sinks to the bottom of your tank, where the fuel is drawn from. At a forecourt — Shell, Esso or another — the staff will normally help roll the vehicle clear, when you ask. Leave it where it is if you're on your own drive in Nuncargate. Where your engine has been run by now, pull over somewhere safe and switch it off. On the M1, under 3 miles from Nuncargate, that means the next exit. Roughly how far did it go? Hopping across Nuncargate is less work than a run of under 10 miles to Nottingham, and so say. ## What occurs when our technicians arrive around Nuncargate Outside Kirkby Woodhouse School, close to St John the Evangelist or on your own drive: wherever the vehicle has stopped, our engineers come to it. Those replies decide this work and the quote, so our engineers ask what went in, about how much, and whether it's run. You hear that quote on the phone, before anybody sets off. Emptying the tank comes next, followed by a thorough flush of your system. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it does not wash out on its own — which is why that counts more with AdBlue than with petrol. Once the fuel filter is cleaned — or replaced, where required — clean diesel is added, and finally the car is tested. Before we leave, we start the car and check that it is running smoothly. Using pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine hasn't run need about half an hour after our technicians arrive. Nothing upfront; you settle up that day. Afterwards, the VAT invoice and a report from the engineer go to you for the insurer. Before we get there, take a look at your policy; many include cover for misfuelling. ## About Nuncargate Nuncargate is a suburban area in Nottinghamshire, situated approximately 9.7 miles from Nottingham and 118.8 miles from London.
