--- title: Fenny Drayton: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/fenny-drayton-leicestershire/ location: Fenny Drayton county: Leicestershire latitude: 52.568350 longitude: -1.484520 service: AdBlue in a Diesel Tank updated: 2026-10-07 --- # How It Happens and How to Prevent It: AdBlue in a Diesel Tank in Fenny Drayton Stop reading for a moment when your diesel tank already has AdBlue in it: ignition off, motor off, and ring 0333 366 0103. Normally, when your motor has not run, it is drained and thoroughly purged where the car is around Fenny Drayton. Nothing happened yet? Further down, the page covers the why it happens and the ways to prevent it altogether. ## Two fillers, two tanks: AdBlue in a diesel motor Not one liquid but two: that's how plenty of newer diesels near Fenny Drayton and Mancetter run, with diesel for your motor. 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. Plenty of motors have a single flap for the two, while some move the AdBlue filler to the boot or under the bonnet. The diesel side is topped up at the pump all the time. The AdBlue side is filled far less regularly, normally from a bottle, and usually by somebody who has to stop and think where it goes. Mistakes happen in that gap between the two. ## AdBlue in your diesel tank around Fenny Drayton: how it takes place It is rarely carelessness. Three things tend to line up. Hurry follows from the warning. The car tells you as AdBlue runs low, and a dry tank puts the vehicle into limp mode — so the top-up happens in a rush, before work on a drive off Old Forge Road, or heading home in the car park at The Royal Redgate. Then your car is unfamiliar. A hire car, a new vehicle or a company car puts the fillers where your last one didn't, and the hand gets to for the cap it would have used on the old one. No part stops the tip after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. Whether it takes place in Atterton or the middle of Fenny Drayton, it is the same few seconds. ## Which filler is for AdBlue, and which for diesel? Before you pour anything, whether on a driveway in Higham on the Hill or a forecourt in Fenny Drayton, check these. They take a few seconds. - Position can mislead; the cap doesn't. AdBlue ones tend to be blue or carry the name "AdBlue" — diesel caps normally do not. - On many vehicles, the size gives it away: AdBlue gets the smaller filler neck. - Lift the filler flap and check for a label — many vehicles show which belongs in each inlet right there. - The handbook. If your filler is not by the diesel cap, it is in your boot or under the bonnet, and the handbook says which. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park outside Atherstone, ask before you leave, not when the light comes on. ## Topping up AdBlue without it reaching the diesel tank The day the light goes on, wherever around Leicestershire, use this routine. - Park and switch off. Not on a slope, not with the engine running, and not in a rush on the side of George Fox Lane. - Locate the AdBlue filler, check the cap, and speak the name "AdBlue" out loud while you unscrew it. It seems daft. It works. - The diesel cap remains on. When both share a flap, make sure it's shut before the bottle comes up. - Gently does it, through the bottle's own spout, till it is full or the bottle runs out. - Before you start the vehicle, close the cap and look again that your diesel cap was never came off. 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. ## AdBlue in your diesel tank already, in Fenny Drayton? The short order of things, starting with no starting the engine. The fuel pump runs on plenty of diesels the moment the ignition goes on — and so leave it off. Filling up with diesel won't thin it: rather than mixing, AdBlue sinks to the bottom of the tank, right where the fuel is taken from. Ask the attendants to help push the vehicle away from the pump if you're on a forecourt — the Nitrogen Station, the Fueling Zone or somewhere else. Leave it where it is if you're on your own drive in Fenny Drayton. Stop as soon as it is safe then switch off, if your engine has already run. The next exit is the place to leave if you are on the M69, under 10 miles from Fenny Drayton. About how far did it go? Hopping across Fenny Drayton is less a job than a run of under 15 miles to Coventry, and so tell us. ## Our arrival around Fenny Drayton, and what happens next Anywhere the vehicle has stopped, be it by Witherley Church of England Primary School, beside George Fox Monument or on your own drive, the van travels to it. What liquid was put in, the quantity, and whether it ran: we ask because those answers decide both work and price. Nobody sets off before you've had the quote over the phone. After that: a drain, then a full flush of the whole system. More than with petrol, it counts with AdBlue: crystals build up, certain metals are attacked, and none of it washes out on its own, however long it sits. Testing comes last: before that, fresh diesel goes in, and the filter is flushed or changed as needed. Before we go, our engineers start it and confirm that it's running properly. If the motor has not run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a busy forecourt and quiet enough to use outside a house at night. Nothing upfront; you settle up that day. At the end, a VAT invoice and a report from the engineer go to you for your insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours while we're on the way. ## About Fenny Drayton and where it is Fenny Drayton is a small village in Leicestershire, situated in the East Midlands region of England, with a population of around 527 people.
