--- title: AdBlue in a Diesel Tank Finchingfield? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/finchingfield-essex/ location: Finchingfield county: Essex latitude: 51.968470 longitude: 0.451160 service: AdBlue in a Diesel Tank updated: 2026-10-27 --- # Finchingfield: How Does AdBlue End Up in a Diesel Tank, and How Do You Prevent It? If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and the ignition off then call 0333 366 0103. A drain and a thorough flush, done just where the vehicle stands around Finchingfield, is usually what it takes if found before your engine runs. The rest of this page explains why it occurs and how to make sure it does not — useful if you are reading ahead of time. ## AdBlue in a diesel motor: two tanks, two fillers Plenty of newer diesels on the roads around Finchingfield and Bridge End carry two liquids, not one. Diesel goes to your engine. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. There is a filler for each tank. Under one flap, side by side: that's the layout on a lot of motors. Elsewhere, AdBlue's filler is beneath the bonnet or in the boot instead. Filling the diesel side at the pump goes on all the time. The AdBlue side is filled far less frequently, usually from a bottle, and normally by a person who has to stop and think where it goes. That gap is where the error lives. ## AdBlue in your diesel tank in Finchingfield: how it occurs Three things tend to line up, and carelessness is rarely one of them. On a driveway off Bridge Street before work, or in the car park at The Fox Inn heading home: that's where the rushed top-up takes place. Why the rush? As AdBlue gets low your car warns you, and if it's gone, limp mode follows. New-to-you motors are next, too. Rentals, new cars and company cars place their fillers differently, and the hand goes for the cap used on the old one. No part halts the tip once it has started, since a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It's seconds, whether in Duck End or right in the heart of Finchingfield. ## How to tell the AdBlue filler from the diesel one A few seconds is all the checks take — so run through them before you tip anything, on a driveway in Hawkins Hill or a forecourt in Finchingfield. - Where it sits can mislead; the cap doesn't. AdBlue ones tend to be blue or carry the word "AdBlue" — diesel ones usually don't. - Plenty of motors give AdBlue the smaller filler of the two. - Lift the filler flap and check for a label — many cars mark which goes in which filler just there. - The handbook. If the filler is not by the diesel cap, it is in the boot or under the bonnet, and the handbook says which. - Whoever had it before will know. Ask as you pick up a rental or fleet car — from Braintree's car park, perhaps — not once the light appears. ## Keeping AdBlue out of the diesel tank when you top up For the day the warning appears — wherever you are around Essex — a simple routine to use. - Park then switch off. Not on a slope, not with the motor running, and not in a rush on the side of The Pightle. - Silly as it sounds, speaking "AdBlue" aloud while you unscrew the cap works — once you've found your filler and read it. - Both under one flap? Then confirm the lid on your diesel filler stays shut before raising the bottle. - Finish once your tank fills or the bottle is empty; until then, pour gently through its built-in spout. - Close the cap and check once more. Make sure the diesel cap was never opened. Only then start the vehicle. Stop there if you find, at step two or three, that you've already poured into the diesel side. Stage five stays out. ## Put AdBlue in your diesel tank in Finchingfield already? Brief list, then. First: the motor stays off. Keep the ignition off as well, because on plenty of diesels switching it on alone runs your fuel pump. AdBlue doesn't 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 thin it. Ask the staff to help roll your car clear of the petrol pump if you are at a forecourt — the Gulf, the Tillbrooks Garage or anywhere else. Your own driveway in Finchingfield is where it should stay. Already started? Stop when it's sensible, then switch off. Finchingfield lies under 10 miles from the M11; there, use the first junction. Tell us about how far it went: a run towards Chelmsford, under 25 miles away, is a bigger job than a short hop across Finchingfield. ## Our arrival in Finchingfield, and what happens next Outside Finchingfield St John the Baptist CofE Primary Academy, close to Fitchingfield Village Sign or on your own driveway: wherever your car has stopped, we come to it. Both the work and our quote depend on three answers — which fluid, which quantity, and if it's run — so our technicians ask. On the call itself, you hear our price — ahead of dispatch. Next: draining, then a thorough flush of the entire system. Much more than with petrol, it matters here: crystals build up, some metals corrode, and none of it clears away unaided, however long it sits. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and your car is tested. After that we start it and confirm it runs properly before leaving. With pumps safe on a busy forecourt and quiet enough for use outside a house at night, most jobs in which the engine has not run take about half an hour after we are there. Nothing in advance; you settle up on the day. At the end, the VAT invoice and the report from the engineer go to you for the insurer. Plenty of insurance policies include misfuelling cover, and so it's worth checking yours whilst we're on the way. ## About Finchingfield, for a moment Finchingfield is a village situated in the county of Essex, located on the riverside at an elevation of 67 metres.
