AdBlue already in your diesel tank? Then set this page aside for now, leave the ignition and engine off, then call 0333 366 0103. Caught before your engine runs, it's generally a drain and a thorough flush, done where the car is around Cropwell Bishop. Reading before the event? Then what follows explains how it happens and what to stop it ever happening. ## Two fillers, two tanks: AdBlue in a diesel motor Many newer diesels around Owthorpe, as well as Cropwell Bishop, run on two fluids; the engine takes only the diesel. The exhaust, not your engine, is where AdBlue ends up: dosed into the gas to clean them, from its own tank. Separate tanks, different fillers. On a lot of vehicles the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. At the pump, the diesel side is topped up all the time. The AdBlue side is topped up far less often, normally from a bottle, and usually by someone who has to stop and think where it goes. Mistakes happen in the gap between them. ## Cropwell Bishop: how AdBlue in your diesel tank happens It is rarely carelessness. Three things tend to line up. First, the warning. Low AdBlue brings a warning from the vehicle, and letting it run out leads to limp mode — hence a hurried top-up, perhaps before work off Fern Road, perhaps at The Wheatsheaf on the way home after work. Unfamiliar cars are second, as well. Rentals, new cars and company vehicles place their fillers in new places, and the hand goes for the cap it used on the old one. No part halts the pour after it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, be it in Blue Hill or right in the centre of Cropwell Bishop. ## Which filler is for AdBlue, and which for diesel? Whether a Cropwell Bishop forecourt or a drive over in Colston Bassett, take a couple of seconds on these before anything goes in. - Position misleads; the cap doesn't. AdBlue ones tend to be blue or carry the name "AdBlue" — diesel caps normally don't. - On plenty of cars, the size tells: AdBlue has the smaller filler neck. - Look inside the fuel flap: many cars have a label there saying which fuel goes where. - The handbook shows which it lives if the filler is not next to your diesel cap: your boot, or under the bonnet. - The person who drove the vehicle last. On a hire or company car collected from somewhere like the car park outside Radcliffe (Nottinghamshire), ask before you leave, not when the light comes on. ## AdBlue top-ups that never reach your diesel tank The day the light goes on, wherever around Nottinghamshire, follow this routine. - Park then switch off. Not on a slope, not with the engine running, and not in a rush on the side of Church Street. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds silly and it works. - The diesel cap stays on. Where the two share a flap, confirm it is shut before lifting the bottle. - Using the bottle's own spout, tip slowly — and stop when it is full or the bottle is empty. - Only after that, start the vehicle: close the cap, check again, and make sure the diesel cap was never opened. Stop there if you find, at stage two or three, that you've already poured into the diesel side. Leave out stage five altogether. ## Put AdBlue in your diesel tank around Cropwell Bishop already? What follows is a short order of things, beginning with no starting your motor. Don't switch your ignition on; on plenty of diesels that alone runs the fuel pump. AdBlue does not mix with diesel — it sinks to the bottom of the tank, where your fuel is sucked from — so do not top up with diesel to dilute it. On a forecourt — Applegreen, JET or any other — the staff will usually help roll the vehicle away, when you ask. If you are on your own driveway around Cropwell Bishop, leave the vehicle where it is. Already run? Stop once it is safe, then switch off. Cropwell Bishop sits under 15 miles from the M1; on it, take the first exit. Tell us about how far it went: a run towards Nottingham, under 10 miles away, is a bigger job than a short hop across Cropwell Bishop. ## Cropwell Bishop: what occurs when we arrive Our van comes to your car wherever it stopped — your own driveway, near St Giles, or by Cropwell Bishop Primary School. Our engineers ask what went in, roughly how much, and if it's run, since those answers determine the work and the price. During the call itself, you are told our quote — ahead of anything else. Emptying the tank comes next, then a full flush of your system. Unlike petrol, AdBlue forms crystals and eats at some fuel-system metals, and neither clears away by itself. Hence it matters more. A test is last: before that, fresh diesel is added, and your filter is cleaned or changed as needed. Your engine is started next and checked to make sure it runs smoothly, all before our engineers go. Most jobs are finished in about half an hour once our engineers get there, as long as your motor has not run — and the pumps our engineers use are safe on a live forecourt and quiet after dark beside a house. Your insurer usually wants the engineer's report and your VAT invoice, and both are yours once this job is done. Payment comes on the day, with no money upfront. Plenty of insurance policies include misfuelling cover, and so it is worth checking yours whilst we are on the way. ## About Cropwell Bishop, briefly Cropwell Bishop is a village in Nottinghamshire, situated approximately 7.6 miles south of Nottingham, and is characterized by its semi-detached housing stock.
