Normally, if the motor has not run, it is emptied and fully flushed where the car sits around Little Linford. Reading before the event? In that case what follows covers how it comes about and what to prevent it happening at all. ## AdBlue in a diesel car: two tanks, two fillers Diesel goes to your engine — yet plenty of newer diesels seen around Little Linford and Gayhurst carry a second liquid as well. AdBlue's own tank holds it, and from there it is sent to your exhaust, and there spraying cleans the fumes. There is a filler on each tank. Many of motors share a single flap for both, while some move the AdBlue filler to your boot or under the bonnet. At the pump, your diesel side is topped up all the time. Much less often, the AdBlue side gets topped up — mostly from a bottle, by a person working out where it goes. It is in the gap that the error happens. ## Little Linford: how AdBlue in the diesel tank happens Seldom is it carelessness: usually three things line up. To start with, the warning. Low AdBlue brings a warning from the car, and letting it run out leads to limp mode — so a rushed top-up, perhaps before work off Little Linford Lane, perhaps at the pub in the village on the way home after work. The old car's cap is where the hand goes — but a hire car, a new motor or a company car puts the fillers elsewhere. That's a second thing: a new motor. A spouted bottle meets no obstacle at a diesel filler no more than at an AdBlue one. And so the tip, once started, keeps on. Whether it takes place in Redhouse Park or the middle of Little Linford, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart Check these first, on a forecourt around Little Linford or a driveway over in Great Linford. Seconds, no more. - The cap. The AdBlue cap is frequently blue, or marked "AdBlue". Your diesel cap normally is not. Read it rather than going by position. - Many vehicles fit AdBlue the smaller filler of the two. - Lift the flap and check for a label — many cars show which goes in which filler just there. - Can't see it next to the diesel inlet? In that case look below the bonnet or in the boot — the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — when you pick up a hire or company car from somewhere like the car park outside Wolverton. ## AdBlue top-ups that never reach your diesel tank For the day the warning appears — wherever you are in Buckinghamshire — a routine to use. - Switch off once parked — flat ground, motor stopped, and never in a rush beside M1 at the roadside. - Locate the AdBlue filler, read the cap, and say the word "AdBlue" aloud as you unscrew it. It seems daft. It works. - The two under one flap? Then make sure the lid on the diesel filler is still shut ahead of raising the bottle. - Stop once your tank fills or the bottle is empty; until then, tip gently using the built-in spout. - Before starting the vehicle, close the cap and check a second time that your diesel cap never opened off. Stop there if you find, at step two or three, that you have already poured into the diesel side. Stage five is off limits. ## Little Linford: already put AdBlue in your diesel tank? Short list, then. Top of it: the motor remains off. Leave your ignition off as well, since on plenty of diesels it by itself runs your fuel pump. Diluting it with more diesel won't work, because AdBlue settles to the bottom instead of mixing — and that's where your fuel is pulled from. The attendants at Shell, Esso or any forecourt will normally lend a hand pushing the vehicle away if asked. Your own driveway around Little Linford is where it stays. Already started? Pull over when it's sensible, then switch off. On the M1, under a mile from Little Linford, that means the next junction. A short hop across Little Linford is a smaller job than a run towards Milton Keynes, under 5 miles away, so tell us roughly how far it went. ## Our arrival around Little Linford, and what takes place next Our technicians come to the vehicle wherever it has stopped, whether that is outside Portfields Primary School, close to St Leonard or on your own drive. Those replies determine this work and the quote, so our technicians ask what went in, about how much, and if it has run. No one heads out until you have heard our price over the phone. Your system is then cleaned thoroughly, once your tank is cleared. Much more than with petrol, it matters here: crystals form, certain metals are attacked, and none of it clears out unaided, no matter how long it is left. The filter cleaned or, where needed, replaced; clean diesel in; and then a test of the vehicle. Next we fire it up and make sure it runs correctly before we go. Most jobs are finished in roughly half an hour once our engineers arrive, provided your motor hasn't run — and the pumps we use are safe on a busy forecourt and quiet after dark beside a house. No money in advance; you settle up that day. At the end, a VAT invoice and the report from the engineer are handed to you for the insurer. While we travel, take a look at your insurance documents; many include cover for misfuelling. ## About Little Linford itself Little Linford is a small hamlet situated on the riverside in Buckinghamshire, with a low elevation of around 77 metres.
