--- title: AdBlue in a Diesel Tank Badbrook? Read This canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/badbrook-gloucestershire/ location: Badbrook county: Gloucestershire latitude: 51.748910 longitude: -2.216060 service: AdBlue in a Diesel Tank updated: 2026-10-25 --- # Avoiding AdBlue in a Diesel Tank in Badbrook: Why It Happens If AdBlue is already in your diesel tank, stop reading for a moment: leave your motor and the ignition off and phone 0333 366 0103. A drain and a thorough flush, carried out right where your car stands around Badbrook, is normally what it needs if caught before your motor runs. Nothing happened yet? Below, the page explains the why it takes place and the ways to prevent it for good. ## Two fillers, two tanks: AdBlue in a diesel motor Diesel goes to your motor — but many current diesels seen about Badbrook and Uplands hold another liquid too. Kept in a tank of its own, AdBlue is sprayed into the exhaust stream to clean it. There is a filler on each tank. Under one flap, next to each other: that is the arrangement on many vehicles. Elsewhere, AdBlue's filler is under the bonnet or in the boot instead. At the petrol pump, your diesel side is topped up constantly. The AdBlue side is filled far less commonly, normally from a bottle, and normally by a person who has to stop and think where it goes. It is in the gap that the slip lives. ## How does AdBlue in your diesel tank take place around Badbrook? It is seldom carelessness. Three things tend to line up. The warning comes first. As AdBlue runs low your car tells you, and if it runs out completely, your vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off Delmont Grove before work, or in the car park outside The Queen Victoria on the way home. The old car's cap is where your hand reaches — yet a hire car, a new vehicle or a company car puts the fillers elsewhere. That is the second thing: an unfamiliar motor. A spout-topped bottle meets no resistance at a diesel filler no more than at an AdBlue one. So the tip, after begun, keeps on. Whether it occurs in Beeches Green or the middle of Badbrook, it's the same few seconds. ## Telling the AdBlue filler from the diesel filler Check these before pouring, at a forecourt around Badbrook or a drive over in Mount Pleasant. A few seconds, no more. - Where it sits misleads; the cap does not. AdBlue ones are often blue or bear the name "AdBlue" — diesel caps usually don't. - Plenty of motors give AdBlue the smaller neck of the two. - Check inside the fuel flap: plenty of motors have a label there saying which fuel goes where. - In the boot or under the bonnet: that is where your filler is if it is not by the diesel cap, and the handbook says which. - Ask the person who drove it last — before you leave, not when the light comes on — if you pick up a hire or company car from somewhere like the car park outside Stroud. ## Keeping AdBlue out of the diesel tank when you top up For the day the light comes on — anywhere you are across Gloucestershire — a simple routine to use. - Switch off after you park — level ground, motor stopped, and not in a rush by Shooters End on the verge. - Find the AdBlue filler and read the cap. Say "AdBlue" out loud as you unscrew it. It sounds daft and it works. - The diesel cap stays on. Where the two share a flap, make sure it's shut before the bottle comes up. - Using the bottle's own spout, pour slowly — and stop when it is full or the bottle is empty. - Before you start the car, shut the cap and look a second time that your diesel cap was never came off. Stop there if you find, at stage two or three, that you've already poured into the diesel side. Skip step five altogether. ## Badbrook: already put AdBlue in your diesel tank? What follows is a short order of things, starting with not starting the motor. On plenty of diesels the ignition alone runs the fuel pump, and so do not switch the vehicle on. Topping up with diesel will not thin it: rather than mixing, AdBlue sinks to the bottom of the tank, right where fuel is drawn from. If you're on a forecourt, whether it is the Tesco or the BP, ask the attendants to help roll the vehicle away from the pump. If you're on your own drive around Badbrook, leave the vehicle where it is. Where the motor has run by now, stop somewhere safe and turn the car off. The next junction is the place to come off if you're on the M5, under 5 miles from Badbrook. Mileage counts — a short hop across Badbrook makes a smaller job than driving under 10 miles to Gloucester — so say roughly how far it went. ## Badbrook: what happens when our engineers turn up The van reaches the vehicle anywhere it has come to rest — your own drive, beside Lockinghill Studio, or by Uplands Community Primary School. The answers settle the work and our price, and so our technicians ask what went in, roughly how much, and whether it's run. No one heads out until you have had the quote by phone. Then the tank is drained and the system rinsed thoroughly. AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't wash out on its own — which is why that counts more with AdBlue than with petrol. The fuel filter is cleaned, or replaced where it needs to be; fresh diesel goes in; and the car is tested. Before we leave, we start it and make sure that it's running smoothly. Most jobs are finished in roughly half an hour once we get there, provided your motor has not run — and the pumps we use are fine on a busy forecourt yet quiet at night beside a house. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. While we travel, have a look at your insurance documents; many include cover for misfuelling. ## About Badbrook and where it is Badbrook is a suburban area located on the riverside in Gloucestershire, with an elevation of 61 metres.
