--- title: AdBlue in a Diesel Tank Kibworth Harcourt? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/kibworth-harcourt-leicestershire/ location: Kibworth Harcourt county: Leicestershire latitude: 52.542220 longitude: -0.992670 service: AdBlue in a Diesel Tank updated: 2026-10-15 --- # Avoiding AdBlue in a Diesel Tank in Kibworth Harcourt: Why It Happens If AdBlue is already in your diesel tank, stop reading for a moment: leave the engine and your ignition off and phone 0333 366 0103. Caught before the engine runs, it is usually a drain and a thorough flush, done where the vehicle is in Kibworth Harcourt. If you're reading before it has happened, the rest of this page is about why it happens and how to make sure it does not. ## Why does AdBlue in a diesel vehicle need its own filler? Not one fluid but two: that is how plenty of modern diesels around Kibworth Harcourt and Carlton Curlieu carry, with diesel feeding the motor. Its own tank holds it, and from there it goes to the exhaust, and there a spray treats the fumes. Every tank has one filler of its own. Plenty of cars have a single flap for both, while others move the AdBlue filler to the boot or under the bonnet. Topping up the diesel side at the pump happens all the time. Seldom filled, AdBlue normally comes out of a bottle, poured by a driver who has to stop and think which cap to use. The slip lives in that gap. ## How AdBlue in your diesel tank happens in Kibworth Harcourt Carelessness rarely explains it. What does is three things lining up at once. To start with, the warning. Low AdBlue triggers a warning from your car, and letting it run dry leads to limp mode — hence a rushed top-up, maybe before work off Harborough Road, perhaps outside Coach and Horses on the way home that evening. The old car's filler is where the hand reaches — yet a hire car, a new car or a company car keeps the fillers somewhere else. That's the second thing: an unfamiliar car. A spouted bottle finds no resistance at a diesel filler no more than at an AdBlue one. And so the pour, after started, keeps on. Whether it takes place in Kibworth Beauchamp or the middle of Kibworth Harcourt, it is the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart A couple of seconds is all the checks take — so check them before you tip anything, on a driveway in Saddington or a forecourt in Kibworth Harcourt. - Blue and marking: an AdBlue cap is regularly blue, or says "AdBlue", where a diesel cap normally does not. Trust the cap, not its position. - On many cars, the size gives it away: AdBlue has the smaller filler neck. - Open the filler flap and check for a label — many vehicles show which goes in which filler right there. - In your boot or under the bonnet: that is where the filler is if it's not by your diesel cap, and the handbook says which. - The person who drove it last. On a hire or company car collected from somewhere like the car park outside Market Harborough, ask before you leave, not when the light comes on. ## How to top up without AdBlue in your diesel tank When the light goes on, wherever across Leicestershire, use this routine. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Marsh Drive. - Locate the AdBlue filler, check the cap, and say the name "AdBlue" out loud while you unscrew it. It sounds daft. It works. - The diesel cap stays on. When the two sit under a flap, confirm it's shut before lifting the bottle. - Stop once your tank fills or the bottle runs dry; until then, tip slowly using the own spout. - Close the cap and check again. Make sure the diesel cap was never opened. Only then start the vehicle. Spot at step two or three that it's already gone into the diesel side? Then stop right there. Don't carry on to step five. ## Put AdBlue in your diesel tank around Kibworth Harcourt already? Don't start the motor: that's how the short order of things begins. The fuel pump runs on plenty of diesels the moment the ignition is switched on — and so keep it off. Filling up with diesel won't dilute it: instead, AdBlue drops to the base of your tank, just where fuel is drawn from. The attendants at Mobil, BP or any forecourt will normally lend a hand pushing the vehicle clear when you ask. Your own driveway around Kibworth Harcourt is the place it should stay. Already run? Pull over once it is sensible, then switch off. Kibworth Harcourt lies under 10 miles from the M1; there, take the next junction. Distance counts — a quick hop across Kibworth Harcourt is a smaller job than heading under 10 miles towards Leicester — so tell us roughly how far it went. ## What happens when we turn up in Kibworth Harcourt Our technicians come to your car wherever it has stopped, whether that is outside Kibworth Church of England Primary School, close to Church Hall or on your own drive. We ask what was put in, roughly how much, and if it's run, because the answers settle the work and the quote. During the call itself, you are told our price — before dispatch. Then that tank is emptied and the system rinsed thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. Your filter is cleaned, or replaced where it needs to be; clean diesel goes in; and the vehicle is tested. Then our engineers fire it up and confirm it runs correctly before leaving. With pumps safe on a working forecourt and quiet enough to use outside a house at night, most jobs in which your motor hasn't run take roughly half an hour after our engineers arrive. No money upfront; you settle up on the day. At the end, the VAT invoice and the report from the engineer are handed to you for the insurer. It is worth looking at your insurance while we travel to you: misfuelling cover is included with many policies. ## About Kibworth Harcourt, briefly Kibworth Harcourt is a village in Leicestershire, situated approximately 8.6 miles southeast of Leicester, and is part of a wider area that includes the nearby villages of Kibworth Beauchamp and Smeeton Westerby.
