--- title: AdBlue in a Diesel Tank Bozeat: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/bozeat-northamptonshire/ location: Bozeat county: Northamptonshire latitude: 52.221600 longitude: -0.675070 service: AdBlue in a Diesel Tank updated: 2026-10-20 --- # How It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Bozeat 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 car stands in Bozeat, is normally what it takes when found before the engine runs. Here before the event? Then the rest explains how it comes about and what to prevent it happening at all. ## AdBlue in a diesel car, and its separate tank Diesel feeds the motor — but many newer diesels seen around Bozeat and Lower End hold another fluid too. AdBlue goes to your exhaust, where it is sprayed into the gas to clean it, and it lives in a tank of its own. Separate tanks, different fillers. On a lot of motors the two sit side by side under the same flap; on others the AdBlue filler is in the boot or under the bonnet. Diesel goes in on every forecourt visit, week in, week out. A driver who has to stop and work out where it goes normally tops up the AdBlue side, from a bottle, and far less commonly. The mistake grows in the gap between them. ## How AdBlue in your diesel tank occurs in Bozeat It is seldom carelessness. Three things tend to line up. On a driveway off Warners Hill before work, or in the car park at The Red Lion on the way home: that's where the rushed top-up takes place. What is the reason for the rush? As AdBlue gets low your car warns you, and once it's empty, limp mode kicks in. The old car's filler is where the hand goes — yet a rental car, a new motor or a company car puts the fillers somewhere else. That is the second factor: an unfamiliar motor. Nothing halts the pour after it has started, because a bottle with a spout goes into a diesel filler as readily as an AdBlue one. The bottle fits. It takes seconds, whether in Easton Maudit or bang in the heart of Bozeat. ## The AdBlue filler and the diesel filler: telling them apart Look at these first, on a forecourt in Bozeat or a drive out in Wollaston. A few seconds, that's all. - Colour and lettering: an AdBlue cap is commonly blue, or says "AdBlue", where a diesel cap normally doesn't. Go by the cap, not its position. - Plenty of motors fit AdBlue the smaller filler of the two. - The flap. Look inside the fuel flap for a label. Plenty of cars say there which fuel goes where. - The handbook says which it is when your filler isn't next to the diesel cap: your boot, or under the bonnet. - The person who drove the vehicle last. On a hire or company car picked up from somewhere like the car park at Wellingborough, ask before you leave, not when the light comes on. ## How to top up without AdBlue in the diesel tank The day the light comes on, anywhere around Northamptonshire, follow this routine. - Not in a rush on the side of High Street, not on a slope, not with your motor running: park and switch off first. - Daft as it sounds, speaking "AdBlue" out loud as you unscrew the cap does the trick — after you have found the filler and read it. - Both under a single flap? Then confirm the lid on the diesel side stays shut ahead of lifting the bottle. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Before starting the vehicle, close the cap and look again that the diesel cap never opened off. If at step two or three you find you have already poured into your diesel side, stop there. Skip step five entirely. ## Already put AdBlue in the diesel tank in Bozeat? Then the order of things is short. Do not start your engine. Leave the ignition off as well, since on many diesels it alone starts the fuel pump. Thinning it with more diesel fails, since AdBlue sinks to the base rather than mixing — and that's where your fuel is sucked from. At a forecourt — Applegreen, Yardley Hastings Garage or another — the attendants will usually help roll your car away, when you ask. At home in Bozeat? Then the car stays where it is. When your engine has run already, stop safely and turn it off. The next exit is the place to leave if you are on the M1, under 10 miles from Bozeat. Distance matters — a quick hop across Bozeat is a smaller job than heading under 15 miles to Milton Keynes — so tell us roughly how far it went. ## Our arrival in Bozeat, and what happens next Our technicians come to the car wherever it has stopped, whether that's outside Bozeat Community Primary School, close to Bozeat Independent Wesleyan Chapel or on your own drive. Both the work and the price depend on three answers — which fluid, which quantity, and whether it has run — so we ask. That quote comes over the phone, ahead of any van leaving. Then that tank is drained and the fuel system cleaned thoroughly. More than with petrol, it counts with AdBlue: the crystals build up, certain metals are attacked, and nothing clears out on its own, however long it is left. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Next our engineers fire it up and confirm it runs smoothly before leaving. If your motor hasn't run, the majority of jobs take about half an hour once we are there, using pumps that are fine on a working forecourt and quiet enough to use outside a house at night. Nothing in advance; you settle up on the day. At the end, the VAT invoice and a report from the engineer are handed to you for the insurer. Before we get there, take a look at your policy; plenty include cover for misfuelling. ## About Bozeat and where it is Bozeat is a village in Northamptonshire, situated in the East Midlands region of England, with an elevation of around 79 metres above sea level.
