--- title: AdBlue in a Diesel Tank Lowford: Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/lowford-hampshire/ location: Lowford county: Hampshire latitude: 50.890420 longitude: -1.316360 service: AdBlue in a Diesel Tank updated: 2026-10-11 --- # AdBlue in a Diesel Tank in Lowford: How It Happens and How to Prevent It If AdBlue is already in your diesel tank, stop reading for a moment: leave your engine and the ignition off and ring 0333 366 0103. Normally, when your engine hasn't turned, it's emptied and fully cleaned where your vehicle sits around Lowford. Here before the event? Then what follows covers why it happens and what to prevent it ever happening. ## AdBlue in a diesel motor: two tanks, two fillers Diesel goes to the motor — yet plenty of newer diesels driven around Lowford and Netley Hill hold a second fluid too. Your exhaust, not the engine, is where AdBlue goes: dosed into the fumes to clean it, from its own tank. Each tank comes with one filler of its own. Many of vehicles share a single flap for the two, while others put the AdBlue filler to the boot or under the bonnet. Topping up your diesel side at the pump happens constantly. A driver who has to stop and work out where it goes usually fills the AdBlue side, from a bottle, and far less commonly. That gap is where the error lives. ## Lowford: how AdBlue in the diesel tank takes place Carelessness rarely causes it. Instead is three things lining up at once. To start with, the warning. Low AdBlue triggers a message from the vehicle, and running out leads to limp mode — so a hurried top-up, maybe before work off Sunnyfield Rise, perhaps at Linden Tree on the way home after work. Then the vehicle is new. A hire car, a new motor or a company car puts the fillers where your last one didn't, and your hand reaches for the cap it would have used on the old one. Third, the spout goes in: diesel filler or AdBlue filler, it slides in just as easily, and after the pour begins, nothing halts it. Oak Hill or the middle of Lowford: it takes the same few seconds either way. ## How to tell the AdBlue filler from the diesel one Whether a Lowford forecourt or a drive out in Hightown, take a couple of seconds over these before any is poured in. - Blue and lettering: an AdBlue cap is frequently blue, or says "AdBlue", where a diesel cap usually doesn't. Go by the cap, not where it sits. - On many vehicles, the size gives it away: AdBlue gets the smaller filler neck. - Check inside your fuel flap: many cars have a label there showing which fuel goes where. - In your boot or under the bonnet: that's where the filler is if it is not by your diesel cap, and the handbook says which. - The person who drove the car last. On a hire or company car picked up from somewhere like the car park outside Bursledon, ask before you leave, not when the light comes on. ## Keeping AdBlue out of the diesel tank when you top up The day the light comes on, anywhere around Hampshire, follow this routine. - Park and switch off. Not on a slope, not with your engine running, and not in a rush on the side of Humber Gardens. - Locate the AdBlue filler, check the cap, and say the word "AdBlue" aloud while unscrewing it. It seems daft. It works. - If both sit under one flap, check the diesel cap is still closed before you lift the bottle — then leave it on. - Pour slowly, using the bottle's own spout. Stop when it's full or when the bottle is empty. - Close the cap and check again. Make sure your diesel cap was never opened. Only then start your car. Discover during the second or third stage that AdBlue went in the wrong tank? That is where you stop. Don't carry on to step five. ## Already put AdBlue in your diesel tank in Lowford? Short order, then. First: the motor stays off. Don't switch the ignition on; on many diesels that alone runs the fuel pump. Diluting it with more diesel fails, since AdBlue sinks to the base rather than mixing — and that's where the fuel is drawn from. If you are on a forecourt, whether it's the Tesco or the BP, ask the attendants to help roll the car away from the pump. Leave it where it is if you're on your own driveway around Lowford. If the engine has already run, stop as soon as it is safe and switch off. The next junction is where to come off if you are on the M27, under a mile from Lowford. About how far did it go? Hopping across Lowford is less work than a trip of under 5 miles to Southampton, so tell us. ## What happens when our engineers turn up around Lowford Anywhere the vehicle came to rest, be it outside Bursledon Junior School(CA), near Bursledon Village Hall or on your own drive, the van travels to it. Our engineers ask what got in, roughly how much, and whether it has run, since the answers settle the work and the quote. That quote comes over the phone, before any van leaves. Emptying your tank comes next, then a thorough flush of your system. Not like petrol, AdBlue leaves crystals and eats at certain fuel-system metals, and neither washes out by itself. That is why it counts more. Your filter is flushed, or replaced where it needs to be; fresh diesel goes in; and the vehicle is tested. Next our technicians start the engine and check it runs smoothly before we leave. If your motor has not run, most 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. You pay on the day, with nothing upfront, and get a VAT invoice and an engineer report for your insurer. It's worth looking at your policy while we travel to you: misfuelling cover is included with plenty of policies. ## About Lowford Lowford is a small village in Hampshire, situated near the coast and approximately 4 miles from Southampton.
