Then set this page down a moment, keep your ignition and engine off, then call 0333 366 0103. Usually, when your motor hasn't turned, it's emptied and thoroughly cleaned where your car sits around Hepthorne Lane. The rest of this page covers why it takes place and how to make sure it doesn't — useful if you are reading ahead of time. ## AdBlue in a diesel motor: two tanks, two fillers Plenty of newer diesels around Lower Pilsley, like those in Hepthorne Lane, carry on two fluids; your engine takes just the diesel. AdBlue goes to the exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Separate tanks, different fillers. Under one flap, side by side: that's the layout on a lot of vehicles. On others, AdBlue's filler sits beneath the bonnet or in your boot instead. Filling the diesel side at the petrol pump happens all the time. Rarely filled, AdBlue normally comes out of a bottle, poured by someone who has to stop and think what cap to use. That gap is where the mistake lives. ## How does AdBlue in the diesel tank take place around Hepthorne Lane? Rarely is it carelessness: normally three things line up. To start with, the warning. Low AdBlue triggers a warning from your car, and running dry leads to limp mode — so a rushed top-up, maybe before work off Glebe Gardens, perhaps outside The Blue Bell on the way home after work. The old car's cap is where your hand reaches — but a hire car, a new motor or a company car keeps the fillers somewhere else. That is a second thing: 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 pour once it has started. The same few seconds decide it, in the middle of Hepthorne Lane or out in Egstow. ## The AdBlue filler and your diesel filler: telling them apart Check these before pouring, on a forecourt around Hepthorne Lane or a driveway over in Parkhouse Green. Seconds, no more. - Read the cap instead of going by where it sits: AdBlue caps are often blue or marked "AdBlue", and diesel ones normally are not. - Many motors fit AdBlue the smaller neck of the two. - A label inside your fuel flap often shows which fuel goes where, on many vehicles. Check for it. - The handbook says which it is when your filler isn't next to the diesel cap: the boot, or under the bonnet. - The person who drove the car last. On a hire or company car collected from somewhere like the car park at Chesterfield, ask before you leave, not when the light comes on. ## Keeping AdBlue out of the diesel tank when you top up Wherever in Derbyshire the light comes on, this is a routine for that day. - Stop somewhere level, engine off, with time in hand — never rushing on the side of Market Street. - Daft as it sounds, saying "AdBlue" out loud as you unscrew the cap does the trick — once you have found your filler and read it. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the vehicle on. - Slowly is best, through the bottle's own spout, till it is full or the bottle runs out. - Only after that, start the vehicle: close the cap, check a second time, and make sure your diesel cap was never opened. Spot at stage two or three that it has already gone into your diesel side? So stop right there. Stage five is off limits. ## AdBlue in your diesel tank already, around Hepthorne Lane? What follows is a short order of things, beginning with not starting the engine. On many diesels your ignition alone runs the fuel pump, and so do not switch the car on. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where the fuel is pulled from — so do not top up with diesel to thin it. At a forecourt — The Co-operative, Tesco or any other — the staff will normally help roll the car away, when you ask. Leave it where it is if you are on your own drive in Hepthorne Lane. Already started? Stop when it's sensible, then switch off. Hepthorne Lane lies under 3 miles from the M1; there, use the first junction. About how far did it go? Hopping across Hepthorne Lane is smaller a job than a trip of under 15 miles to Sheffield, so tell us. ## Hepthorne Lane: what occurs when we turn up Outside North Wingfield Primary and Nursery Academy, near St Lawrence or on your own driveway: wherever the car has stopped, our technicians come to it. Our engineers ask what was put in, about how much, and whether it has run, since those answers determine this work and the quote. Nobody heads out before you've had our quote over the phone. Then your tank is emptied and your system flushed thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own. After the fuel filter has been cleaned — or renewed, if required — clean diesel is added, and then your car is tested. After that our engineers fire it up and confirm it runs correctly before leaving. If your engine has not run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. Nothing upfront; you settle up on the day. Afterwards, a VAT invoice and the report from the engineer go to you for your insurer. Misfuelling cover is included in many insurance policies — and so make use of the wait to look at yours. ## About Hepthorne Lane itself Hepthorne Lane is a locality situated in a riverside setting in Derbyshire, with an elevation of around 132 metres.
