--- title: Poolfields: AdBlue in a Diesel Tank, Explained canonical: https://www.petrolinadieselcar.co.uk/adblue-in-diesel/poolfields-staffordshire/ location: Poolfields county: Staffordshire latitude: 53.010230 longitude: -2.237910 service: AdBlue in a Diesel Tank updated: 2026-10-24 --- # Why It Occurs and How to Avoid It: AdBlue in a Diesel Tank in Poolfields Leave the engine and ignition off and phone 0333 366 0103 first — reading can wait when AdBlue is already in the diesel tank. A drain plus a full flush, carried out right where your car sits around Poolfields, is normally all it needs when caught before the motor runs. If you're reading before it has happened, the remainder of this page is about why it happens and how to make sure it does not. ## AdBlue in a diesel vehicle, and its separate tank Plenty of current diesels on the roads round Poolfields and The Brampton carry two liquids, not one. Diesel goes to your engine. Kept in a tank of its own, AdBlue is fed into your exhaust stream to clean it. Each tank has a filler of its own. Many of vehicles have a single flap for the two, while some move the AdBlue filler to your boot or under the bonnet. At the pump, the diesel side gets filled all the time. Much less often, the AdBlue side gets topped up — normally from a bottle, by a person working out where it goes. Mistakes happen in the gap between them. ## AdBlue in your diesel tank around Poolfields: how it happens Carelessness seldom explains it. Instead is three things coming up at once. The warning comes first. As AdBlue runs low the vehicle tells you, and if it runs out altogether, the vehicle goes into limp mode. So the top-up is done in a hurry: on a drive off St. Mary's Drive before work, or in the car park outside The Thistleberry on the way home. The old car's filler is where the hand reaches — yet a hire car, a new vehicle or a company car keeps the fillers elsewhere. That's a second factor: a new vehicle. Lastly, the bottle goes in: diesel filler or AdBlue one, it slides in as readily, and once the pour begins, nothing stops it. Whether it occurs in Newcastle-under-Lyme or the middle of Poolfields, it's the same few seconds. ## The AdBlue filler and the diesel filler: telling them apart A few seconds is all these take — so check them before you pour anything, on a driveway in Cross Heath or a forecourt in Poolfields. - Check the cap rather than going by position: AdBlue ones are regularly blue or marked "AdBlue", and diesel caps usually are not. - Check the size: the smaller filler neck is, on plenty of vehicles, the AdBlue one. - The flap. Look inside your fuel flap for a label. Plenty of motors say there which fuel goes where. - The handbook says which it is when your filler is not next to the diesel cap: the boot, or under the bonnet. - Ask the person who drove it last — before you leave, not when the light comes on — when you collect a hire or company car from somewhere like the car park outside Longport. ## AdBlue top-ups that never reach your diesel tank When the light goes on, anywhere across Staffordshire, follow this routine. - Park and switch off. Not on a slope, not with your motor running, and not in a rush on the side of Saint Paul's Road. - Say "AdBlue" out loud as you unscrew the cap, after you find the AdBlue filler and read it. Silly, perhaps, yet it does the trick. - If both sit under one flap, check your diesel cap is still closed before you lift the bottle — and leave it on. - Stop when your tank is topped up or the bottle is empty; before that, tip gently using its own spout. - Only after that, start the car: close the cap, check once more, and make sure your diesel cap was never opened. Find at stage two or three that it's already gone into the diesel side? Then stop just there. Stage five stays off limits. ## Poolfields: already put AdBlue in the diesel tank? Short list, then. First: the motor stays unstarted. On plenty of diesels your ignition alone runs the fuel pump, and so do not switch the vehicle on. AdBlue does not mix with diesel — it sinks to the bottom of your tank, where your fuel is drawn from — so do not top up with diesel to dilute it. If you are on a forecourt, whether it is the Texaco or the Sainsbury's, ask the staff to help roll your car away from the petrol pump. If you are on your own driveway in Poolfields, leave the vehicle where it is. Already run? Stop when it is sensible, then switch off. Poolfields sits under 3 miles from the M6; there, use the next exit. About how far did it go? Crossing Poolfields is smaller a job than a trip of under 3 miles to Stoke-on-Trent, so tell us. ## What takes place when our technicians get there around Poolfields The van reaches the car wherever it stopped — your own driveway, beside Newcastle under Lyme Castle, or by St Giles' and St George's Church of England Academy. What fluid went in, the amount, and whether it ran: we ask because those replies decide both work and quote. That quote is given over the phone, ahead of any van leaving. Then your tank is emptied and the fuel system cleaned thoroughly. With AdBlue that matters more than with petrol: it crystallises and is corrosive to some of the metals in a fuel system, and so it does not wash out on its own. The fuel filter is flushed, or replaced where it needs to be; clean diesel goes in; and the car is tested. Then we fire it up and check it runs correctly before we go. If the engine hasn't run, most jobs take about half an hour once we are there, using pumps that are safe on a busy forecourt and quiet enough to use outside a house after dark. Nothing upfront; you settle up that day. Afterwards, the VAT invoice and a report from the engineer go to you for the insurer. It is worth looking at your policy as the van travels to you: misfuelling cover is included with plenty of policies. ## About Poolfields and where it is Poolfields is a suburban area located on the riverside in Staffordshire, with a mix of semi-detached housing and a population of around 5165 residents.
