Caught before the engine runs, it's generally a drain and a thorough flush, done where your car is around Hilton. Nothing happened yet? Further down, the rest of the page explains the why it occurs and the how to avoid it altogether. ## Why does AdBlue in a diesel car need its own filler? Diesel goes to your engine — but plenty of current diesels seen about Hilton and Etwall hold a second fluid too. Kept in a tank of its own, AdBlue is fed into your exhaust gas to clean it. There's a filler on every tank. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in your boot or under the bonnet. At the pump, your diesel side gets filled constantly. A driver who has to stop and work out where it goes normally fills the AdBlue side, from a bottle, and much less frequently. The mistake lives in that gap. ## How does AdBlue in the diesel tank take place in Hilton? Carelessness rarely explains it. What does is three things coming up at once. On a driveway off Main Street before work, or in the car park outside The Old Talbot heading home: that is where the hurried top-up takes place. What is the reason for the rush? As AdBlue gets low the vehicle warns you, and if it's empty, limp mode kicks in. Unfamiliar motors are second, too. Hire cars, new vehicles and company motors place their fillers differently, and the hand goes for the cap it used on the old one. Third, the spout goes in: a diesel filler or AdBlue one, it goes in just as easily, and once the pour starts, nothing stops it. Whether it occurs in Burntheath or the middle of Hilton, it's the same few seconds. ## Telling the AdBlue filler from your diesel filler Before you pour anything, whether on a driveway in Etwall Common or a forecourt in Hilton, check these. They take a few seconds. - Read the cap rather than going by position: AdBlue caps are regularly blue or marked "AdBlue", and diesel ones usually are not. - On many cars, size gives it away: AdBlue has the smaller filler neck. - Look inside your fuel flap: many cars carry a label there saying which fuel goes where. - Can't find it beside your diesel inlet? In that case look below the bonnet or in the boot — the handbook will say which. - Collecting a hire or company car, perhaps at the car park outside Tutbury & Hatton? Check with whoever drove the car last before you set off, not when the light goes on. ## AdBlue top-ups that never reach your diesel tank For the day the light comes on — wherever it is around Derbyshire — a simple routine to follow. - Not in a rush on the side of Egginton Road, not on a slope, not with your engine running: park and switch off properly. - Find the AdBlue filler, read the cap, and say the name "AdBlue" aloud as you unscrew it. It sounds daft. It works. - Leave your diesel cap on. If both sit under one flap, check the diesel cap is still closed before you lift the bottle. - Gently does it, through the bottle's own spout, till it is full or the bottle runs out. - Shut the cap, and look again — making sure the diesel filler remained shut the whole time. After that, start the car. If at step two or three you find you have already poured into the diesel side, stop there. Don't go on to step five. ## AdBlue in the diesel tank already, around Hilton? Short list, then. First: the engine stays unstarted. The fuel pump starts on many diesels as soon as the ignition goes on — and so leave it off. Do not top up with diesel to dilute it: AdBlue doesn't mix with diesel, it sinks to the bottom of that tank, where your fuel is sucked from. Ask the attendants to help push the vehicle away from the petrol pump if you are at a forecourt — the Essar, the BP or somewhere else. Your own drive around Hilton is where it stays. Where your motor has been run already, stop somewhere safe and switch the car off. Hilton sits under 15 miles from the M42; there, use the first exit. About how far did it go? Crossing Hilton is less a job than a trip of under 10 miles to Derby, so say. ## Hilton: what occurs when our technicians arrive Outside Hilton Spencer Academy, near Hilton Methodist Church or on your own driveway: wherever the vehicle has stopped, our technicians come to it. The answers determine this work and our price, so we ask what was put in, roughly how much, and whether it has run. On the phone call itself, you hear our price — before dispatch. After that: a drain, then a thorough flush of the entire system. More than with petrol, it matters here: the crystals build up, certain metals are attacked, and none of that clears away unaided, no matter how long it sits. The filter flushed or, if it must be, replaced; fresh diesel in; and then a check of your vehicle. We do not leave until it has been started and is running smoothly. Unrun vehicles mostly mean a half-hour visit from arrival. The kit is safe on a busy forecourt, and hushed enough for a residential street after dark. Paying happens on the day, not upfront, and you receive the paperwork an insurer wants: an engineer report and a VAT invoice. Before we get there, have a look at your policy; many include cover for misfuelling. ## About Hilton, briefly Hilton is a village in Derbyshire, situated on the riverside at an elevation of around 60 metres, with detached housing being the predominant type of accommodation. Hilton lies approximately 7.5 miles from Derby and 114 miles from London, making it a commuter-friendly location. Hilton is surrounded by nearby places such as Burntheath, Marston on Dove, and Hatton Fields, and has a population of around 1726 residents. Hilton enjoys a peaceful setting, with the river running through the village. ## AdBlue drains about Hilton, and Derbyshire beyond Hilton is a village, and our vans that cover it also work the places near it, Marston on Dove and Hatton Fields among them, across the DE postcode area. Fastest of all: give a DE65 5 postcode for the van. The vehicle does not need to move. We drain it where it is — a side street close to Hilton Village Hall, a lay-by on the way to Hilton Park, a driveway. Assuming won't help at the back of Sculpture Garden, on a border, or somewhere awkward to describe; ring and check. ## Hilton drivers: the short version Pour nothing till you have read the cap. If AdBlue has gone in your diesel tank all the same, leave the car off then phone 0333 366 0103. Petrol in Diesel drains it where it waits, anywhere across Derbyshire.
