Then put this page down for now, keep your ignition and engine off, then phone 0333 366 0103. Around Evenley, catching it before your engine turns normally means a drain and a thorough flush where it stands. Reading before the event? Then what follows explains why it comes about and how to prevent it happening at all. ## AdBlue in a diesel vehicle, and its separate tank Diesel feeds your motor — but plenty of newer diesels driven around Evenley and Hinton-in-the-Hedges carry another fluid too. The exhaust, not your engine, is where AdBlue ends up: sprayed into the gas to clean them, from a separate tank. Separate tanks, different fillers. Many of vehicles have a single flap for the two, while others move the AdBlue filler to your boot or under the bonnet. At the petrol pump, the diesel side gets filled all the time. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and far less regularly. That gap is where the slip lives. ## AdBlue in your diesel tank in Evenley: how it takes place It's hardly ever carelessness. Three things tend to line up. First, the warning. Low AdBlue triggers a message from the car, and letting it run out means limp mode — hence a rushed top-up, maybe before work off Church Leys, or outside Red Lion on the way home that evening. Then, the hand reaches for the cap it knew on the old vehicle — since a hire car, a new motor or a company car puts the fillers where your last one did not. No part stops the tip after it has started, since a bottle with a spout goes into a diesel filler as easily as an AdBlue one. The bottle fits. It's seconds, be it in Juniper Hill or bang in the centre of Evenley. ## Telling the AdBlue filler from your diesel filler Before you tip anything, whether on a driveway in Turweston or a forecourt in Evenley, check these. They take a couple of seconds. - Check the cap rather than going by where it sits: AdBlue ones are frequently blue or marked "AdBlue", and diesel caps normally aren't. - The size. On many vehicles the AdBlue filler neck is the smaller of the two. - A label inside the fuel flap frequently says which fuel goes where, on many cars. Look for it. - Cannot find it next to the diesel inlet? Then look below the bonnet or in the boot — the handbook will say which. - Collecting a hire or company car, perhaps at the car park at Kings Sutton? Check with the person who drove the vehicle last before you set off, not when the light goes on. ## AdBlue top-ups that never reach your diesel tank Wherever in Northamptonshire the light comes on, here is a routine for that day. - Not in a rush on the side of Broad Lane, not on a slope, not with the engine running: park then switch off first. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — then leave the car on. - Finish once the tank is topped up or the bottle runs dry; before that, tip slowly through its own spout. - Close the cap and check a second time. Make sure your diesel cap was never opened. Only then start your car. Stop there if you find, at step two or three, that you've already poured into your diesel side. Don't go on to step five. ## Evenley: already put AdBlue in the diesel tank? Brief list, then. First: your motor stays unstarted. Don't switch the ignition on; on many diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where the fuel is pulled from — so don't top up with diesel to dilute it. On a forecourt — Tesco, Sainsbury's or another — the staff will usually help push the car away, if you ask. On your own drive in Evenley? Then the vehicle stays put. Stop as soon as it is safe and switch off, if your engine has already run. On the M40, under 5 miles from Evenley, that means the next exit. Tell us about how far it went: a run towards Milton Keynes, under 25 miles away, is a bigger job than a short hop across Evenley. ## Our arrival in Evenley, and what happens next Our van reaches your car wherever it stopped — your own driveway, near Evenley Village Hall, or by Waynflete Infants' School. Our engineers ask what went in, roughly how much, and whether it's run, because the answers settle this work and the price. That price comes on the call, ahead of any van leaving. Then that tank is cleared and the fuel system flushed thoroughly. More than with petrol, it counts here: the crystals build up, certain metals corrode, and none of that clears out unaided, however long it sits. Testing comes at the end: before that, clean diesel goes in, and your filter is flushed or replaced if necessary. After that we fire it up and make sure it runs correctly before leaving. Most jobs are finished in roughly half an hour after our technicians get there, provided your motor hasn't run — and the pumps we use are fine on a live forecourt and quiet at night beside a house. The insurer will ask for the engineer's report and the VAT invoice, and you get both at the end. Payment is on the day, with no money upfront. It's worth looking at your insurance while we travel to you: misfuelling cover is included with many policies. ## About Evenley Evenley is a small village in Northamptonshire, situated in the East Midlands region of England, with a population of around 584 people.
